Girls Around the World Are Seeing a Surge in Mustache Growth — Doctors Warn Skincare Products Packed with Hormone Disruptors May Be the Cause

Across TikTok and Reddit, thousands of women are asking the same alarming question: “Why am I suddenly growing facial hair?”

Dermatologists and endocrinologists are starting to sound the alarm — the culprit may be what you’re putting on your skin.

The Hidden Hormone Disruptors Lurking in Skincare

Many popular skincare and cosmetic products contain endocrine-disrupting chemicals (EDCs) — synthetic compounds that mimic or block natural hormones like estrogen.

Over time, these chemicals can confuse your body’s hormone balance, leading to issues like irregular cycles, acne, mood swings… and yes, unexpected hair growth.

Sources note that “the skin absorbs up to 60% of what we put on it — yet most people have no idea that many ingredients in skincare were never tested for long-term hormonal safety.

Sunscreens Are The Worst Offenders

While endocrine-disrupting chemicals (EDCs) can hide in everything from perfumes to moisturizers, experts warn that sunscreens are the most deceptive offenders — even the ones labeled “clean” or “mineral.”

Oxybenzone: The Hormone Mimic

Oxybenzone is a common UV filter found in over 65% of non-mineral sunscreens, and it’s one of the most studied hormone disruptors in skincare.

Research from the Centers for Disease Control and Prevention (CDC) found oxybenzone in the urine of nearly 97% of Americans tested, showing how widespread absorption really is.

Studies show it can mimic estrogen, disrupt thyroid function, and even be detected in breast milk and amniotic fluid, raising serious concerns about long-term exposure.

Butyloctyl Salicylate: the “Clean” Imposter in Mineral Sunscreens

Many so-called “safe” mineral sunscreens now rely on butyloctyl salicylate, a chemical booster that makes zinc oxide spread more evenly.

But few realize it’s a salicylate ester — part of the same chemical family as UV filters like octisalate — and studies suggest it can enhance the skin’s absorption of other chemicals.

In one 2020 toxicity review, butyloctyl salicylate showed potential hormone activity and was listed by the European Chemicals Agency as a suspected endocrine disruptor.

In short: it helps your sunscreen feel silky… but may also help toxins sink deeper.

Synthetic Fragrances and Seed Oils: the Hidden Hormonal Load

Even beyond UV filters, the problem compounds. Many “natural” skincare products still include synthetic fragrances such as diethyl phthalate (DEP) — used to make scents last longer — which the Environmental Working Group (EWG) lists as a known endocrine disruptor and developmental toxin.

And the “plant-based” seed oils used to make formulas sound healthy, like soybean or grapeseed oil, are naturally high in phytoestrogens, compounds that can bind to estrogen receptors and throw off hormonal balance when applied daily.

So while you thought you were protecting your skin or choosing the safer option, your routine might actually be delivering a daily dose of hormone confusion — drop by drop, swipe by swipe.

That’s why a new generation of brands is emerging. One of the pioneers of this movement is Sky & Sol. It is made from ancestral, whole ingredients — like tallow, jojoba, beeswax, and zinc — that nourish and protect naturally, without a single synthetic chemical.
