Topical rapamycin and rapamycin cream for skin

Rapamycin skin cream, sometimes listed as transdermal rapamycin cream, is one of the few longevity products with a real dermatology track record behind it and almost no topical rapamycin evidence in front of it. The gap between those two facts is where most of the marketing lives.

This page holds the two apart. It covers what the trial measured, what strengths of rapamycin cream for face and hands are actually sold, what Hyftor is approved for, and what a prescription sirolimus cream route legitimately looks like. We sell nothing on this page and take no commission from any clinic named on it.

What is topical rapamycin?

Topical rapamycin is sirolimus formulated for application to the skin rather than swallowed, where it inhibits mTOR locally in keratinocytes and dermal fibroblasts.^[6] As an mTOR inhibitor it is used on-label as Hyftor 0.2% gel for facial angiofibromas in tuberous sclerosis complex, and off-label as compounded sirolimus at concentrations from 0.001% to 8% for skin aging. It is prescription-only in the United States in every form.

The appeal is straightforward. Oral rapamycin suppresses mTOR throughout the body, with the systemic trade-offs that implies. A cream aims the same mechanism at the tissue you can see, and the trial evidence suggests that at low concentrations it stays there.^[7]

How we assess claims on this page

Every health claim here carries a citation to a primary source, and where a study is small we print the sample size next to the result rather than the p-value alone. That is the whole of our method, and it is the reason this page reads differently from the clinic pages ranking beside it.

• Sample sizes, not just significance. A p-value from eight people is reported as a p-value from eight people.
• Honest comparison. We state who each option is not for, not only who it suits.
• No prescription sales. We do not sell, supply or facilitate any prescription drug, and we earn nothing from the routes described below.
• Dated corrections. When the evidence changes, the page changes and says so. Our editorial standards page sets out how that works.

We have no in-house clinician and claim none. What we have is the literature, read carefully and cited line by line.

Does topical rapamycin work?

On the only randomized evidence that exists, there is a genuine mechanistic signal from a very small number of people. The trial enrolled 36 adults over 40, 17 completed the protocol, and 8 provided tissue samples that could be analyzed.^[1] In those samples the senescence marker p16INK4A fell significantly (p = 0.008) and collagen VII protein rose (p = 0.0077).

Participants also showed decreased fine wrinkles, increased dermal volume, improved skin tone, less skin sagging and reduced vein prominence. No treatment-related adverse events were reported.

Read plainly: this is the beginning of an evidence base. It has not been replicated, and no confirmatory trial has followed in the years since.

One exploratory trial · 8 analyzable participants · not replicated

The trial was on hands, not faces

Participants applied 0.5 cc of 0.001% rapamycin to the dorsal hands every 24 to 48 hours for six to eight months.^[1] The face was not the treated site.

Every facial before-and-after image circulating under this keyword is therefore an extrapolation from hand skin, which differs from facial skin in thickness, sebum production and sun-exposure history. The extrapolation may well hold. It has not been tested.

The concentration problem nobody selling it explains

Published topical sirolimus formulations span a concentration range of 0.001% to 8%, an eight-thousand-fold spread, and there are no comparative dose response trials establishing an optimal strength.^[2] The only anti-aging trial sits at the very bottom of that range.

Clinics commonly offer 0.01%, 0.25% and a 1% rapamycin cream. Those are ten times, two hundred and fifty times and one thousand times the strength behind the trial's 8 analyzable samples.

Higher is not better-evidenced here. Higher is simply unstudied for this purpose, which is a different and much less comfortable statement.

Concentration, evidence and what is actually sold

If a clinic will not tell you which concentration it is dispensing, you cannot place it on this table. That is reason enough to ask before paying. The same reasoning applies to oral dosing, where the studied ranges are equally specific and equally often rounded up in practice.

How rapamycin acts on skin at the cellular level

Rapamycin binds and inhibits mTOR, the nutrient-sensing kinase that drives cell growth. In aging skin, senescent cells among the keratinocytes show elevated mTOR activity alongside IGF-2 overexpression, a state associated with cellular hypergrowth and the accumulation of p16INK4A.

Inhibiting mTOR locally is intended to interrupt that loop. The trial's endpoints were chosen to test the mechanism directly rather than to produce a flattering photograph, which is a point in its favor even at n = 8.

Skin autophagy is frequently cited as a third mechanism, alongside claims about the skin barrier and resilience against UV damage and oxidative stress. All are plausible and well described elsewhere in rapamycin biology, and none was demonstrated in this human skin trial. We separate the two in our explainer on how rapamycin inhibits mTOR.

Is sirolimus cream available over the counter?

No. Every topical sirolimus formulation is prescription only in the United States, and sirolimus cannot lawfully appear in the ingredient list of a US cosmetic. Cosmetic use is off label use in every case.

This has a practical consequence worth internalising before you shop. A product sold over the counter as rapamycin cream either does not contain sirolimus, or is not being sold lawfully. Read the ingredient list, and if sirolimus is named on a cosmetic sold without a prescription, that is a red flag rather than a feature.

Can I buy rapamycin over the counter?

No, and the same applies to the tablets. Oral rapamycin is dispensed as sirolimus and is licensed for the prevention of transplant rejection.^[9] Every longevity use is off-label and requires a prescriber.

We do not supply it, do not link to a checkout for it, and do not recommend any route that bypasses a clinician. The practical picture for the oral form is covered in rapamycin cost and how people access it.

Hyftor: the one approved topical sirolimus, and what it is approved for

Hyftor is sirolimus topical gel 0.2%, the first and only FDA-approved topical sirolimus product.^[3] Its licensed indication is facial angiofibroma associated with tuberous sclerosis complex, in patients aged 6 and over.^[4]

It is not approved for skin aging. That distinction matters the moment a clinic cites FDA approval at you while selling a compounded anti-aging cream, because the approval belongs to a different product treating a different condition.

The dermatologic track record predates the longevity interest

Topical sirolimus was being used for angiofibromas well before anyone framed it as an anti-aging compound, and it has been studied in conditions including facial discoid dermatosis and vitiligo.

This history is genuinely the strongest honest argument for topical rapamycin: the safety of putting this molecule on facial skin is not being invented from scratch. It is also why the aging evidence looks so thin by comparison, because the dermatologic literature sets a bar the cosmetic literature has not met.

Nobody's going to make enough money off of rapamycin to do the clinical trials that really should be done.

How much of it gets into your blood

In the 0.001% trial, no blood sample collected contained detectable rapamycin, against an assay detection limit of 1 ng/mL.^[1] Nothing measurable crossed over at that strength.

Reviews covering the wider 0.001% to 8% range report a different picture: levels that are measurable but remain below the 4 ng/mL immunosuppressive threshold.^[2]

Both statements are true, and together they say something the marketing does not. The reassurance about systemic absorption is strongest at the lowest concentrations and weakens as concentration rises, which is one more reason to know which strength you have been given.

What is the downside of rapamycin?

The topical rapamycin side effects that show up most are local and manageable: dryness, peeling, redness and itching at the application site, usually mildest after the first week.

Photosensitivity is the one that changes your routine. Local irritation fades; sun sensitivity does not, so SPF 30 daily at broad spectrum stops being optional. It is contraindicated in pregnancy, planned pregnancy and breastfeeding.

Then there is the downside no product page lists. At every strength above 0.001%, the person applying it is the dose-finding study, because the dose-finding study has not been done.

Who this is not for

• Anyone pregnant, planning pregnancy or breastfeeding. This is a hard contraindication, not a caution.
• Anyone immunosuppressed or on immunosuppressive therapy. A prescriber's call, and not a close one to make casually.
• Anyone unwilling to wear sunscreen every day. The photosensitivity is real and the whole point is reducing photoaging.
• Anyone wanting a result inside eight weeks. The trial measured nothing before month six.
• Anyone who cannot get a straight answer on concentration. Without that number, nothing else on this page applies to your product.

Topical rapamycin vs tretinoin

On evidence weight this is not close, and pretending otherwise would be dishonest. Topical retinoids carry decades of large randomized trials for photoaging, fine lines, skin texture and skin elasticity. Topical rapamycin has one exploratory trial with eight analyzable participants.

They also do different things. Retinoids act on retinoic acid receptors and drive cell turnover; rapamycin acts on mTOR and appears to target the senescent phenotype, a mechanism we unpack alongside collagen and skin aging.

No head-to-head trial has compared them. Anyone declaring a winner is guessing, in either direction.

Can they be layered?

Clinic guidance commonly suggests alternating nights rather than same-night layering, because both compounds raise photosensitivity and stacking them compounds the irritation risk.

Chemical peels, microdermabrasion and laser resurfacing should be avoided on treated areas. If significant redness or peeling appears, the usual advice is to pause rather than push through. All of that is prescriber territory and none of it is a protocol we issue.

Can you get rapamycin naturally?

No. Rapamycin is a macrolide produced by Streptomyces hygroscopicus, a soil bacterium collected on Rapa Nui in the 1960s, which is where the name comes from.^[9]

It is not present in any food, plant or botanical extract at a meaningful concentration, and the body does not make it. Supplements marketed as natural rapamycin alternatives contain other compounds with some mTOR-adjacent activity in cell culture, which is a far weaker claim resting on far weaker evidence. We take that apart in natural alternatives to rapamycin.

A note on before-and-after photos

Most of the striking imagery attached to this keyword comes from angiofibroma case series, not aging trials. Those are dramatic results for a different condition.

Beyond that, lighting, camera angle and facial expression move apparent wrinkle depth more than most topical actives do. The 2019 trial's primary outcome was a protein measured in a biopsy, precisely because photographs are unreliable.^[1]

Three questions defuse almost any before-and-after: what was measured, over how long, and in how many people.

Where can I buy rapamycin cream?

Through a prescription, and there is no fourth option. Searches for where to buy rapamycin cream turn up three legitimate routes in the United States, and we supply none of them and earn nothing from any of them.

1. A compounded prescription. A clinician, usually a board certified dermatologist, writes for a specific concentration and vehicle, and a compounding pharmacy prepares it for you individually.
2. Hyftor, for its licensed indication. Prescribed for facial angiofibroma in tuberous sclerosis complex and dispensed through normal pharmacy channels.^[3]
3. Licensed telehealth. Clinics that conduct a medical review, prescribe, and arrange dispensing through a certified pharmacy.

What compounded actually means

Compounded drugs are not FDA-approved. They are not reviewed for safety, efficacy or quality before they are dispensed, which is a legal fact about the category rather than a criticism of any particular pharmacy.

Two kinds of facility make them. A 503A compounding pharmacy prepares your individual prescription; a 503B outsourcing facility produces in bulk under stricter manufacturing requirements.

Ask which one made yours, and ask for the certificate of analysis: pharmaceutical-grade material is typically specified near 99.5% purity, with potency verification confirming each batch potency within 10% of label, plus trace metal testing. A compounder that will not answer has told you what you needed to know.

Buying from overseas pharmacies

Export listings for sirolimus cream appear openly in image search results for this keyword, and the price difference is substantial.

Personal importation of unapproved prescription drugs into the United States is generally not lawful. There is no chain of custody, no certificate of analysis and no recourse if the potency is wrong, which on a molecule where concentration is the entire question is a poor trade. We do not link to these sellers and do not recommend the route.

What it realistically costs

Prices displayed in US search results in August 2026 give a working range: one telehealth treatment listed from $115 per month, and one compounded 20 gram facial cream at $190.

Those are the rapamycin cream price points sellers displayed on the date we checked, not quotes, and compounded pricing moves with concentration and quantity. Verify before ordering.

Insurance rarely covers compounding for a cosmetic indication, and HSA or FSA eligibility varies by plan. The figure that matters is not the first month but six to eight of them, because that is the duration the only supporting trial ran.

How people actually use it

The pattern reported across clinic instructions is consistent: apply in the evening to clean, dry skin, using a pea sized amount, starting at two to three nights per week and increasing as tolerated.

Broad-spectrum SPF 30 or higher goes on every morning without exception. Dryness in the first week is the most commonly reported complaint and usually settles.

That is reported practice, not our recommendation. Your prescriber's instructions override every line of it.

What six months of it actually looks like

Three starting points change how that timeline reads. Someone already on oral rapamycin has a total-exposure question to raise with their clinician. Someone retinoid-experienced has a tolerance advantage and a scheduling problem. Someone using their first active ingredient should probably not start with the one that has eight analyzable participants behind it.

Should you try it? An honest decision aid

• If you want proven wrinkle data, a topical retinoid has the far larger evidence base, and rapamycin is a speculative addition rather than a replacement.
• If you have tuberous sclerosis angiofibromas, topical sirolimus is an approved therapy for exactly that. See a dermatologist.^[4]
• If you want the trial's evidence specifically, that means 0.001%, on the hands, for six to eight months. Very few clinics offer it.
• If you are drawn to the mechanism, read the senescence argument first and decide whether an n of 8 justifies the spend.^[5]
• If a clinic will not state the concentration, you already have your answer.

Questions to take to a prescriber

The most useful thing this page can hand you is a short list to bring to the person who can actually prescribe.

1. What concentration are you prescribing, and what evidence supports that concentration for skin aging?
2. Which pharmacy compounds it, is it 503A or 503B, and may I see the certificate of analysis?
3. How will we judge whether it is working, and by what date?
4. What are the stopping criteria, and what happens to my skin if I stop?
5. Given my current routine, does this displace something with better evidence?

If you arrived here from an old rapamycin-cream link, the honest position has not moved much: locally acting, prescription-grade, with a real dermatologic history and one encouraging trial in eight people behind the cosmetic claim. The systemic picture is a different and much better-studied question, covered in the main rapamycin evidence guide.

Frequently asked questions

Does topical rapamycin work?

Partly, on very thin evidence. One exploratory randomized trial enrolled 36 adults over 40, 17 completed it, and 8 provided tissue that could be analyzed. In those samples the senescence marker p16INK4A fell (p = 0.008) and collagen VII rose (p = 0.0077). That is a real mechanistic signal from eight people, not proof that a cream smooths your face.

Where can I buy rapamycin cream?

Only through a prescription. A clinician writes for a compounded cream and a compounding pharmacy prepares it, or a dermatologist prescribes Hyftor for its licensed indication, or a licensed telehealth clinic prescribes and dispenses. There is no legal retail rapamycin cream in the United States, and we do not sell or supply any of these routes.

Is sirolimus cream available over the counter?

No. Sirolimus is the generic name for rapamycin and every topical form is prescription-only in the United States. Sirolimus cannot legally appear in the ingredient list of a US cosmetic, so any product sold over the counter as rapamycin cream either does not contain the drug or is not being sold lawfully.

Can I buy rapamycin over the counter?

No, and that applies to the tablets as well as the cream. Oral rapamycin is dispensed as sirolimus, licensed for the prevention of transplant rejection. Every longevity use of it, oral or topical, is off-label and requires a prescriber.

What is the downside of rapamycin?

For the topical form the common downsides are local: dryness, peeling, redness, itching, and increased sun sensitivity that makes daily SPF 30 or higher non-negotiable. It is contraindicated in pregnancy, planned pregnancy and breastfeeding. The downside nobody advertises is that at most strengths sold, you are the dose-finding study.

Can you get rapamycin naturally?

No. Rapamycin is a macrolide produced by the soil bacterium Streptomyces hygroscopicus, first collected on Rapa Nui. No food, plant extract or supplement contains it. Products marketed as natural rapamycin alternatives contain different compounds with weaker evidence, which is a different claim entirely.

What concentration of rapamycin cream should I use?

That is a prescriber's decision, but the evidence context matters. The only randomized anti-aging trial used 0.001%. Published formulations run as high as 8%, and clinics commonly offer 0.01%, 0.25% and 1%. No comparative dose-response trial has ever been run, so strengths above 0.001% are not better-studied, they are simply unstudied for this purpose.

How much does topical rapamycin cost per month?

On prices displayed in US search results in August 2026, one telehealth treatment was listed from $115 per month and one compounded 20 gram facial cream at $190. Insurance rarely covers compounding for a cosmetic indication. Budget across six to eight months, because that is the duration the trial actually ran.

Is topical rapamycin better than tretinoin?

On evidence weight, no. Topical retinoids carry decades of large randomized trials for photoaging. Topical rapamycin has one exploratory trial with eight analyzable participants. They also act differently, retinoids on cell turnover and rapamycin on mTOR and senescence, and no head-to-head trial has compared them.

Can I use topical rapamycin and a retinoid together?

Clinic guidance commonly suggests alternating nights rather than layering them on the same night, because both raise photosensitivity. Avoid chemical peels, microdermabrasion and laser treatments on treated skin. This is genuinely a prescriber conversation and not a protocol we issue.

Does topical rapamycin get into your bloodstream?

In the 0.001% trial, no blood sample contained detectable rapamycin at an assay limit of 1 ng/mL. Reviews covering the wider concentration range report measurable but sub-threshold levels against a 4 ng/mL immunosuppressive threshold. The reassurance is strongest at the lowest concentrations, which is another reason concentration matters.

What is Hyftor, and is it the same as a compounded rapamycin cream?

Hyftor is sirolimus topical gel 0.2%, the first and only FDA-approved topical sirolimus. It is licensed for facial angiofibroma in tuberous sclerosis complex in patients aged 6 and over. It is not approved for skin aging, and a compounded anti-aging cream is a different, unapproved product.

How long before topical rapamycin does anything?

The trial ran for six to eight months before biopsies were taken, and nothing was measured earlier than that. Expect irritation and dryness in the first fortnight and no measured evidence of benefit before month six. Anyone promising visible change in two weeks is describing marketing.

Are the before-and-after photos real?

Many circulating images come from angiofibroma case series rather than aging trials, and lighting, angle and expression shift apparent wrinkle depth more than most actives do. The 2019 trial's primary outcome was a protein measured in a biopsy, not a photograph. Ask what was measured, over how long, and in how many people.

Can I use topical rapamycin if I already take oral rapamycin?

That is a question for the clinician managing your oral protocol, because it changes the total exposure picture. The topical trial explicitly measured for systemic absorption and found none at 0.001%, but it did not enrol people already taking the drug. We do not issue combined protocols.

Is it legal to buy sirolimus cream from an overseas pharmacy?

Generally no. Personal importation of unapproved prescription drugs into the United States is not lawful in most circumstances, and export listings for sirolimus cream appear openly in image search results. There is no chain of custody, no certificate of analysis and no recourse if the potency is wrong.

How do I know the compounding pharmacy made it correctly?

Ask which pharmacy compounded it and whether it is a 503A pharmacy compounding against your individual prescription or a 503B outsourcing facility producing in bulk. Then ask for the certificate of analysis covering purity, potency tolerance and trace metals. A compounder unwilling to answer is the answer.

What happens if I stop using it?

Nobody has studied it. The trial had no washout arm and no follow-up after treatment ended, so there is no published evidence on whether the biomarker changes persist, fade or reverse. Any confident claim in either direction is invention.
