PCOS skincare: which ingredients help and which to avoid

What does PCOS actually do to your skin?

PCOS produces four skin signs, and the American College of Obstetricians and Gynecologists names all four in one list: excess hair growth on the face, chest, abdomen or upper thighs, which is hirsutism; severe acne, or acne that starts after adolescence and does not respond to usual treatments; oily skin; and patches of thickened, velvety, darkened skin called acanthosis nigricans.

ACOG puts hirsutism at more than 7 in 10 women with PCOS. NICHD, at the National Institutes of Health, publishes the same four signs and adds that many people do not think of oily skin, increased hair growth or acne as symptoms of a serious condition, so they never mention them to a doctor.

The reason those four travel together is that two hormones are doing the work, and both of them arrive at the skin through the blood. ACOG says high androgen levels also cause the unwanted hair growth and acne seen in many women with PCOS, and it is insulin resistance that is associated with acanthosis nigricans. NICHD describes how the two feed each other: the body makes more insulin to push glucose into cells, and to balance high insulin it makes more androgens. Its own conclusion is that it is difficult to disrupt this cycle, which is why treating PCOS can be challenging.

Is my acne PCOS?

Acne on its own is a weak signal, and the 2023 international evidence based guideline for PCOS says so in as many words: healthcare professionals should recognise that female pattern hair loss and acne in isolation, without hirsutism, are relatively weak predictors of biochemical hyperandrogenism. Hirsutism is the opposite: the same guideline says the presence of hirsutism alone should be considered predictive, and puts the threshold at a modified Ferriman Gallwey score of 4 to 6 depending on ethnicity. The AAD’s adult acne page reaches the same place from the other side, listing an undiagnosed medical condition among the reasons adult acne appears, and noting that once it is diagnosed and treated the acne often clears. Acne plus unwanted hair growth is a conversation to have with a doctor. Acne alone, for most people, is just acne, and our post on what actually clears a spot is written for that.

Which skincare ingredients should you avoid if you have PCOS?

No named body has published a list of skincare ingredients to avoid because you have PCOS. ACOG’s PCOS page names no ingredient. NICHD’s page on the treatments for PCOS names none either. And the 2023 international guideline, which runs to 77 evidence based recommendations, 54 consensus recommendations and 123 practice points, does not name a skincare ingredient anywhere in them.

That gap is the reason this page exists. A search for PCOS skincare returns a great many confident lists and almost no citations, and the honest position is that the lists are somebody’s reasoning rather than anybody’s finding. Where nobody has published a rule, this post says so.

There are two real reasons to read a label if you have PCOS, and neither of them is about hormones. The first is acne. ACOG describes PCOS acne as the kind that does not respond to usual treatments, which makes the ordinary advice worth more rather than less, and the AAD’s version of it is specific: look for non-comedogenic, non-acnegenic, oil-free or won’t clog pores on every container, moisturiser and sunscreen included. That is advice for anybody with adult acne. It is not a PCOS rule and it is not presented as one. Which filters are in that sunscreen is a separate question, and our guide to reading sunscreen filters sets out what each body has said about them.

The second is that PCOS is rarely the only profile a person is on. Pregnancy, breastfeeding and trying to conceive are where published ingredient rules actually live, and the overlap is common enough to deserve its own section further down. Truva keeps a PCOS list of its own, and it is worth being clear about what that list is: a precautionary sort of ingredients whose hormone activity has been raised somewhere, not a set of published findings. Nobody has published that removing any of them changes an androgen level. It exists so that a product which is fine for pregnancy does not come back clear for a different question, and it should be read the way this post reads everything else, by what is behind each entry.

What actually helps each PCOS skin sign?

Almost everything published for PCOS skin is a medicine, a procedure or a razor. Laid out as a grid, the column a skincare aisle could fill is the emptiest one on the page, and that is not a judgement about skincare. It is what four named bodies have actually written down.

Hirsutism, the best documented of the four

Unwanted hair growth is the sign with the most published behind it, and almost none of it comes in a bottle. NICHD names shaving, bleaching, plucking, waxing and depilatories as effective at temporarily removing or hiding it, with the caveat that several of them cause irritation and ingrown hairs. Removing hair that often makes those bumps a standing problem, so how to get rid of bumps after waxing or shaving has its own post, including which methods change in pregnancy. The one genuine topical is a prescription: eflornithine cream is FDA approved for the treatment of unwanted facial hair, but no studies have been published about its use specifically in women with PCOS. The hair grows back when you stop. Beyond that the published options are systemic or in a clinic: the 2023 guideline recommends the combined pill, puts anti androgens after a suboptimal response to at least six months of the pill or cosmetic therapy, and recommends mechanical laser and light therapies for reducing facial hirsutism.

Two lines in that guideline are the only PCOS specific skin findings this post could locate anywhere. The first is that a greater number of laser sessions may be required in women with PCOS than in women with hirsutism from another cause, which is worth knowing before paying for a course of sessions. The second is blunter, and it is about a product people buy for exactly this: there is no evidence to support the efficacy of home based IPL kits.

Acne, treated the ordinary way

PCOS acne is treated as acne. NICHD says retinoids, antibacterial agents and antibiotics are the common ways to treat it and that the choice depends on severity, which is the same sentence that would be written for anybody. The AAD splits that list by what you need a prescription for: a non prescription retinoid, adapalene, and benzoyl peroxide are both available in stores, while stronger retinoids and topical antibiotics are not. Truva holds an ingredient page for adapalene and for salicylic acid, both of which carry a PCOS verdict alongside five others.

Where PCOS acne diverges is not the cream, it is what comes after the cream fails. The AAD’s hormonal therapy page is written for exactly the pattern ACOG describes, acne that has not responded to the usual things, and names two options: oral contraceptive pills and spironolactone, and reports that of 85 women whose records were reviewed, a third cleared completely and a third had noticeably less acne. In clinic, the AAD’s position on lasers and lights is that they can reduce acne, and that rarely can these treatments alone clear it. Nothing on any of those pages, and no recommendation in the 2023 guideline, treats PCOS acne differently from other acne. That is the fourth column of the grid, and it is a gap rather than a reassurance.

Acanthosis nigricans, which is not dirt

Thickened, velvety, darkened patches are the sign most often mistaken for something washable, and the AAD addresses that first: people sometimes believe a dye or something they touched has discoloured the skin and try to scrub it away, but vigorous scrubbing will not get rid of it. The AAD’s treatment list holds nothing you can buy over a counter. It is prescription creams, ointments and gels to lighten the colour, laser to reduce thickness, and retinoids, with the note attached that none of those treatments is specifically designed for this. The part that connects back to PCOS is the first line of that page: many people see their skin clear when the condition causing it is treated, and getting pre diabetes under control often helps the patches fade.

Thinning hair, and the one shelf product that works

Female pattern hair loss is the one PCOS related sign with a genuinely effective product on an ordinary shelf. The AAD calls minoxidil the most recommended treatment for it, at 2% or 5%, approved by the FDA without a prescription for women, and asks for six to 12 months before judging. It is equally clear about the products next to it on that shelf: most studies of hair supplements found no effect on hair growth and thickness, and hair loss shampoos cannot regrow hair or prevent hair loss from worsening. Truva keeps an ingredient page for minoxidil, and the reason it is not a simple yes is in the next section.

Oily skin, the sign nobody treats

Oily skin is on both ACOG’s list and NICHD’s list of PCOS symptoms, and neither body publishes anything to do about it. It has no row in the grid above for that reason: four identical cells reading no published rule would be a sentence pretending to be a row. This is the sentence. Plenty has been written about oily skin in general, and none of it by these bodies in connection with PCOS, which is worth stating plainly rather than filling in.

Do hormone disrupting ingredients make PCOS worse?

No named body has published that a cosmetic ingredient makes PCOS worse, or that removing one makes it better. Endocrine disrupting chemicals are a real field with a real literature, and what is in that literature is narrower and considerably stranger than the lists PCOS searches return.

Start with the definition. The National Institute of Environmental Health Sciences describes endocrine disrupting chemicals as natural or human made chemicals that may mimic, block, or interfere with the body’s hormones, and names cosmetics among the everyday products they are found in. Its list of the most common and well studied ones runs to atrazine, bisphenol A, dioxins, perchlorate, PFAS, phthalates, phytoestrogens, flame retardants, PCBs and triclosan. Two of those ten are cosmetic ingredients.

The one entry on that page that names a skincare ingredient outright is not the one anybody expects. Under what NIEHS supported research has found, its puberty item reads that chemicals in lavender oil and tea tree oil are potential endocrine disruptors, associated with premature breast development in girls and abnormal breast development in boys. The rest of that list is attention, immunity, metabolism, preterm birth and reproduction. PCOS is not on it. Neither is acne, hirsutism or anything else in this article.

On the two ingredients every PCOS list names, the FDA’s published position is that it has not found harm at the levels used in cosmetics. On parabens: at this time, we do not have information showing that parabens as they are used in cosmetics have an effect on human health. On phthalates: the FDA does not have evidence that phthalates as used in cosmetics pose a safety risk, with the note that their use in cosmetics fell considerably between its 2004 and 2010 surveys. Both pages say the agency will act if that changes. Neither mentions PCOS, and neither is an all clear about exposure from every source at once, which is the thing NIEHS is actually measuring.

That is three separate statements and not one. The category is real and NIEHS studies it. The FDA has not found harm from these two ingredients as they appear in cosmetics. And nobody has published that either fact changes anything about polycystic ovary syndrome. NIEHS’s own advice is to reduce exposure where you reasonably can, noting that EDCs cannot be completely avoided or removed. That is a sensible thing to do. It is not a PCOS treatment, and a product sold as one is selling something nobody has measured.

Does PCOS change what is safe to put on your skin, in pregnancy or while breastfeeding?

PCOS on its own changes nothing about which ingredient is safe, because no body has published a PCOS specific topical restriction to change it. What does change things is the profile you may be on at the same time, and the overlap here is not a rare case. ACOG says PCOS is one of the most common causes of female infertility, so a great many people meet PCOS treatment and a pregnancy question in the same year.

The uncomfortable part is that the published warnings cluster on exactly the treatments this article has just listed. NICHD says pregnant women should not use eflornithine cream because it can cause harm to a fetus, that those who are or wish to become pregnant should not use retinoids, and that anti androgens can cause congenital anomalies and are often taken with oral contraceptives to prevent pregnancy. The AAD puts the same warning on spironolactone in plainer language: if you get pregnant while taking it, your baby can have serious birth defects, and if you can get pregnant you will need to use birth control while taking it. On the hair side it says women who are pregnant, plan to become pregnant or are breastfeeding should avoid minoxidil, and that all of the prescription alternatives may cause birth defects. Not every body draws the breastfeeding line in the same place, and our post on minoxidil in pregnancy and while breastfeeding sets the AAD’s advice beside the others.

What remains available is the ordinary over the counter layer, and ACOG publishes a list of ingredients that can be used during pregnancy, which includes topical salicylic acid and glycolic acid, alongside the instruction that topical retinoid use is generally recommended to be avoided. That is the same ACOG page a pregnancy question would reach on any other subject, and it is doing all the work here, because the PCOS pages do not carry a topical position of their own. Truva keeps a separate list for pregnancy, for breastfeeding and for trying to conceive, and the reason they are separate lists rather than one is that they disagree with each other, and with the PCOS one, ingredient by ingredient. The comparison pages set out why a scanner that never asks your situation cannot make that split.

If you are trying to conceive

This is the overlap that matters most, because ACOG names PCOS as one of the most common causes of female infertility, so the people reading about PCOS skin and the people reading about conception are heavily the same people. Nothing changes on the topical side, for the same reason as everywhere else on this page: nobody has published a rule. What does carry published instructions is the prescription half of the ladder above, and those instructions are strict. The two medicines with a published stop before you conceive window are set out separately, and the spironolactone and isotretinoin warnings quoted earlier on this page are the reason that post exists.

If you are postpartum

No named body publishes anything about PCOS skin specifically for the postpartum period, and this page is not going to invent one. What changes after a birth is whether you are breastfeeding, which the paragraphs above cover, and whether a prescription paused for the pregnancy is being restarted, which is a conversation with the clinician who paused it rather than a question about an ingredient.

When should PCOS skin go to a doctor?

Three of the four signs above have a published reason to be looked at rather than managed at home. Darker, thicker skin is the clearest: the AAD asks you to see a dermatologist about any such patch, because acanthosis nigricans can be a sign of pre diabetes, and changes made before diabetes develops can prevent it.

Unwanted hair that is new, severe or getting worse is the second. The 2023 guideline asks for further investigation in that case, to rule out androgen secreting tumours and ovarian hyperthecosis, which is not a sentence a hair removal page will tell you. Thinning hair is the third, and it is about timing rather than danger: the AAD says treatment for female pattern hair loss delivers the best results when it is started at the first sign. If hormonal therapy comes up, expect blood tests before a spironolactone prescription and a visit every 4 to 6 weeks while the dose is raised.

And if you are pregnant, breastfeeding or trying to conceive, take the prescription list to your obstetrician or midwife rather than to a search box. On this subject the published warnings are attached to the treatments, not to the cosmetics.

Key takeaways

• PCOS has four published skin signs. ACOG names hirsutism, which affects more than 7 in 10 women with PCOS, severe or late onset acne that does not respond to usual treatments, oily skin, and acanthosis nigricans.
• There is no published list of skincare ingredients to avoid with PCOS. ACOG’s PCOS page, NICHD’s treatments page and the 2023 international guideline name none between them, and the guideline carries 77 evidence based recommendations without a skincare ingredient in any of them.
• What is published is mostly not skincare: the combined pill, anti androgens, insulin sensitising drugs, eflornithine cream, laser and IPL, and ordinary acne treatment. The only two PCOS specific findings in any of these sources are that laser may need more sessions, and that treating insulin resistance often fades acanthosis nigricans.
• On endocrine disruptors, the FDA says it has no information showing parabens as used in cosmetics affect human health and no evidence that phthalates as used pose a safety risk. NIEHS names lavender oil and tea tree oil among potential endocrine disruptors and links them to premature breast development, not to PCOS.
• The ingredient rules that do apply to you are probably not the PCOS ones. Eflornithine, retinoids, anti androgens, spironolactone and minoxidil all carry published pregnancy warnings, and PCOS is one of the most common causes of female infertility, so the two questions arrive together often.
