No. Pause retinol during active chemotherapy.

Stop at diagnosis or at the start of your first cycle, whichever comes first. Do not taper. Do not alternate nights. Do not save it for the days when you feel better. Pause it and keep it paused through the end of active treatment and for a few weeks of barrier recovery afterward.

This is the consensus recommendation across oncology dermatology. Every conventional source agrees, and on this specific question, the sources are right. What most of them fail to give you is the why — the specific mechanisms that make retinol the wrong tool during chemo — and they fail to give you the what now, the alternative that preserves the anti-aging work you were doing before your diagnosis without creating new problems.

This post gives you both.

If you came here looking for permission to keep your retinol in your routine, you are not going to find it. What you will find is a clear explanation of why pausing is the right call, and a specific alternative that most clean-beauty brands cannot offer you because they do not have formulations designed for skin in this particular state.

Your skin during chemotherapy is not the same skin you had three months ago. Even if it looks similar at first, the biology underneath it has changed, and the change matters for every ingredient decision you make.

Chemotherapy works by targeting rapidly-dividing cells. Cancer cells divide rapidly, which is why chemotherapy works on them. But the skin's barrier-producing cells also divide rapidly, which is why chemotherapy damages skin as a predictable side effect. We walked through the underlying biology in What Is Cancer? The Zombie Invasion Explanation and how this shapes every skincare decision in What Skincare Is Best to Use During Cancer Treatment? — the short version is that chemotherapy thins the skin barrier, slows its ability to repair itself, and increases its sensitivity to just about everything it encounters.

Retinol, at its core, is a rapid-cell-turnover drug. It works by telling your skin cells to divide faster, shed their outer layer more quickly, and produce new cells underneath. In normal conditions, this is why retinol is so effective for anti-aging — faster turnover means smoother texture, more even tone, and less visible sign of accumulated sun damage. In a healthy skin barrier, the brief irritation retinol causes is manageable, and the benefits are substantial.

During chemotherapy, the math flips. Four mechanisms turn retinol from a useful tool into a specifically wrong one.

• Barrier disruption on a barrier that is already compromised. Retinol temporarily disrupts the skin barrier as a side effect of its turnover mechanism. On healthy skin, the disruption is minor and transient. On chemo-era skin, where the barrier is already thinner and repairing more slowly than usual, the disruption stacks — you are adding an irritant to a surface that has lost most of its normal capacity to recover from irritation. The result is often significantly more peeling, redness, and sensitivity than the same product produced before treatment.
• Photosensitivity stacked on photosensitivity. Retinol increases the skin's sensitivity to ultraviolet light. So does chemotherapy, through several different mechanisms depending on the specific drugs involved. ¹ 5-fluorouracil, methotrexate, and several other chemotherapies are known photosensitizers; some taxane regimens produce significant sun sensitivity as well. Adding retinol's photosensitizing effect on top of chemotherapy's photosensitizing effect might produce dramatic reactions to sun exposure that neither drug would have caused alone.
• Irritation on reactive skin. Skin during chemo is more reactive to ingredients it previously tolerated without issue. Fragrances that used to be fine can flare. Actives that used to be comfortable can burn. Retinol, which is always at least slightly irritating, is much more likely to cause significant irritation during treatment than during the months before it.
• Interference with repair that is already behind schedule. The skin barrier's ability to rebuild itself is reduced during chemotherapy. Every night your skin is doing repair work it is working uphill. Retinol, which accelerates turnover but does not accelerate barrier repair, can push turnover ahead of what the barrier can keep up with, leaving the outer layer of your skin structurally thinner than it should be.

None of these four mechanisms is subtle, and none of them is controversial in the oncology dermatology literature. Every single one gets worse if you keep using retinol through chemo.

Pausing retinol during chemo means completely stopping, from the day of your diagnosis or the start of your first cycle, until several weeks after your last active infusion. Specifically:

• Stop at diagnosis, not at the start of treatment. The gap between diagnosis and the first cycle is usually at least a few weeks, and it is often the stretch of time when women are most tempted to get one last month of the good routine in before treatment starts. Do not. The skin changes during chemo begin at the first infusion, and restarting normal skin the week before treatment is not useful work.
• Do not taper. Tapering doses is appropriate for some medications but unnecessary here. Retinol is not addictive and there is no withdrawal benefit to gradually stopping. Just stop.
• Do not alternate nights. Using retinol every other night, or twice a week, or only on the good weeks, does not solve the problem. It just applies the four mechanisms above at slightly lower frequency. The skin barrier is still being disrupted every time you use the product, and a compromised barrier does not get the benefit of the other nights to catch up.
• Keep it paused through the end of active treatment. The barrier recovery that begins after your last infusion takes weeks, not days. A reasonable guideline is to wait four to eight weeks after the final cycle before considering reintroduction, and even then, reintroduction should be gradual and carefully monitored. We cover reintroduction in detail in Is Retinol Safe After Chemotherapy?, which is the companion post to this one.
• Pause everything in the retinoid family, not just retinol specifically. The same guidance applies to retinoids in any formulation — retinaldehyde, prescription tretinoin, adapalene, and the newer bakuchiol-conjugate retinoids. All of them work through related mechanisms and all of them carry the same concerns during active chemo.

If you are on a prescription retinoid your dermatologist prescribed, talk to her directly about pausing it. She will confirm the recommendation and may give you specific guidance about when to restart.

Here is what this post is ultimately here to tell you.

You do not have to give up your anti-aging work during chemo. You have to switch tools. The right alternative is a plant compound called bakuchiol, and it has been widely studied as a retinol alternative specifically for skin that cannot tolerate retinol's mechanism.

Bakuchiol produces many of the same anti-aging benefits as retinol — improved texture, reduced visible lines, more even tone — through a genuinely different mechanism that does not disrupt the barrier, does not cause photosensitivity, and does not require the skin to accelerate turnover in a way it may not be able to keep up with. ²³ It has been the subject of clinical trials directly comparing it to retinol, with comparable efficacy on most anti-aging endpoints and dramatically lower irritation and sensitivity. ⁴ For skin during active cancer treatment, bakuchiol is not a consolation prize. It is the correct tool for the job.

Our Age-Well Routine for Sensitive Skin was built around bakuchiol specifically because the compromised barrier it addresses — from treatment, from hormonal transitions, from genetic sensitivity — is the skin state where retinol fails and gentler actives work better. The routine includes our Nighttime Bakuchiol Renewal Cream as the anti-aging hero, paired with a Gentle Cleanser that uses only the mildest plant-derived surfactants, the Deep Hydration Serum for the extra moisture compromised skin needs, the Everyday Hydration Cream for barrier support, and Dry Rescue Drops for the nights your skin is most vulnerable.

For a woman in active chemotherapy, the full routine is the most complete support you can give your skin during treatment. If you are not ready to commit to a full routine right now — which is a completely reasonable thing to feel in the middle of treatment — the two individual products that do the most work for the least effort are the Gentle Cleanser and the Deep Hydration Serum. Both are low-risk, barrier-first, and appropriate for every cancer type and every treatment regimen.

One important note for women with hormone-receptor-positive breast cancer.

If you are being treated for hormone-receptor-positive breast cancer and will be moving onto an aromatase inhibitor after your active chemotherapy, the bakuchiol recommendation comes with a specific nuance. Bakuchiol has been characterized as a weak phytoestrogen in preclinical research, and while there is no published evidence that topical use in a formulated face cream produces clinically meaningful effects, some women on AIs prefer to err on the side of avoiding even weak phytoestrogenic ingredients during their endocrine treatment years. We cover this situation in detail in Using Bakuchiol While on an Aromatase Inhibitor, and the alternative recommendation for that audience is the Deep Hydration Serum as the primary anchor product, with the Green Tea Shield Serum as a defensible secondary.

For chemotherapy specifically — which is shorter in duration and not driven by hormone signaling in the same way — bakuchiol remains the clear recommendation.

One practical reality that most skincare content ignores: you are probably too exhausted to execute a ten-step routine during chemo, and even a moderate routine can feel impossible on the worst days. The reality of treatment is that some days you will want to do the full routine, and some days you will barely want to wash your face before falling into bed.

That is fine. Here is a minimum-viable routine that still covers the fundamentals:

• Morning: Splash of cool water to rinse. Deep Hydration Serum while skin is still damp. Broad-spectrum mineral SPF 30 or higher. (Sunscreen is non-negotiable during chemo regardless of how you feel otherwise, because of the photosensitivity layer above.)
• Night: Gentle Cleanser if you wore sunscreen or feel the need. Deep Hydration Serum on damp skin. Everyday Hydration Cream or, on the rough nights, Dry Rescue Drops applied directly.

That is the whole thing. On good days, add the Nighttime Bakuchiol Renewal Cream into the evening routine. On rough days, skip whatever feels like too much and know that the barrier support you did include is what actually matters.

Your skin is not going to be offended if you do the short version on a hard night. It will be much more offended if you try to keep using retinol and end up with significant peeling, redness, or a reaction that makes the next few days worse.

Can I use retinol on the parts of my face that are not affected?

Retinol affects the skin systemically once absorbed, and chemo affects the skin systemically too. There is not really a part of your face that is not affected in the way this question usually imagines. Pause it everywhere.

What about a very low-strength retinol like 0.1%?

The mechanisms that make retinol problematic during chemo are not dose-dependent in the way the question implies. Lower concentrations are gentler, but they still do the four things above — they just do them a little less severely. Pause it entirely rather than trying to find a tolerable dose.

My dermatologist prescribed tretinoin before my diagnosis. What do I do?

Call your dermatologist and tell her about the diagnosis. She will almost certainly recommend pausing the prescription through active treatment, and she will be the right person to tell you when and how to restart.

Is this permanent? Can I never use retinol again?

For most women, retinol can be reintroduced weeks to months after the end of active chemotherapy, depending on what treatment comes next and how the skin barrier recovers. We cover the reintroduction question in detail in Is Retinol Safe After Chemotherapy?. If you are moving onto endocrine therapy for hormone-receptor-positive breast cancer, the reintroduction question gets more nuanced, and the right answer for some women is to stay on bakuchiol long-term rather than returning to retinol at all.

What if I have been using retinol for the first few weeks of chemo and only now found this post?

Stop now, do not beat yourself up, and give your skin a few weeks of uninterrupted barrier support. You have not done permanent damage — you have been using a product that was not ideal for your current skin state, and stopping is what solves that. If you are experiencing significant peeling, redness, or irritation, the Dry Rescue Drops are specifically designed to help. 

Chemotherapy is temporary. Your skin will recover. The work of protecting the barrier during active treatment is almost entirely about subtraction — removing the actives that were fine before treatment and are no longer fine now — and about gentle support, not about ambitious actives.

Retinol, for the duration of your active treatment, is an active that was fine before and is not fine now. The work you were doing with it can be continued with bakuchiol, which is designed for exactly this kind of skin state. The full Age-Well Routine for Sensitive Skin is the most complete support; the Gentle Cleanser and Deep Hydration Serum are the lowest-effort starting point.

Your skin does not need ambition right now. It needs reinforcement. The ambitious work resumes when your treatment ends and your barrier rebuilds, and we will walk you through that reintroduction when you are ready.
