Teen Skincare — Your First Moisturizer, Cleansing the Face and Busting TikTok Myths

The TikTok algorithm is not a dermatologist. And yet millions of teenagers build their skincare routines around 60-second clips in which peers or influencers recommend retinol, glycolic acid and vitamin C serum. Meanwhile, the American Academy of Dermatology (AAD) has been saying the same thing for years: teenage skin needs simplicity. Three products, not thirteen.

What happens to skin during puberty?

Puberty triggers a hormonal cascade that directly affects the skin. Androgens — testosterone and dehydroepiandrosterone (DHEA) — stimulate the sebaceous glands to increase sebum production by up to 500% compared with the pre-pubescent stage (Zouboulis, Dermato-Endocrinology, 2009).

The consequences:

• Skin becomes oily — especially in the T-zone (forehead, nose, chin).
• Pores enlarge — under the influence of excess sebum and the keratinization of the sebaceous ducts.
• Acne appears — comedones, papules, and in more severe cases inflammatory nodules. It affects 85% of teenagers aged 12–18 (Journal of the American Academy of Dermatology).
• Sweating intensifies — the apocrine glands around the armpits become active, which calls for regular hygiene.

Step 1: Gentle cleansing — not a "war on pimples"

The biggest mistake teenagers make is reaching for harsh cleansers that promise to "dry out the pimples." Products with SLS (sodium lauryl sulfate) and a pH above 7 destroy the skin's lipid barrier, which paradoxically increases sebum production — the skin tries to compensate for the lost lipids.

What should you choose?

• A cleansing gel with a pH of 5.0–5.5 — close to the skin's natural pH. It doesn't have to foam like shampoo to work.
• Mild surfactants: cocamidopropyl betaine, sodium cocoyl isethionate, decyl glucoside. Check the formula in the PurScore ingredient database.
• Wash twice a day — morning and evening. No more than that. Over-washing damages the barrier and worsens acne.

Step 2: A light moisturizer — yes, even for oily skin

"I have oily skin, so I don't need a moisturizer" — that's a myth that dominates among teenagers. Oiliness is excess sebum, not excess water. Skin can be oily and dehydrated at the same time. A lack of hydration leads to:

• The compensatory production of even more sebum.
• Irritation and flaking, which deepen the acne.
• A damaged barrier through which C. acnes bacteria more easily trigger inflammation.

Which formula should you choose?

A light gel-cream or emulsion (lotion) — no heavy oils, no essential oils (they can irritate and sensitize), no artificial dyes. Look for products containing:

• Hyaluronic acid — hydrates without weighing the skin down.
• Glycerin — a humectant with proven benefits.
• Centella asiatica — soothes irritation and supports regeneration.

Step 3: SPF 30 — even in winter, even on cloudy days

Teenage skin is healthier and regenerates faster, but UV damage accumulates from childhood onward. A study by Godar et al. (Photochemistry and Photobiology, 2003) found that around 25% of a person's total lifetime UV dose is received before the age of 18. Protection during this period therefore carries disproportionately large significance for the future health of the skin.

• SPF 30 is a sufficient minimum for everyday use.
• Light, mattifying sunscreen formulas are better tolerated by oily teenage skin.
• There are no excuses: SPF protects against skin cancer, hyperpigmentation and premature aging.

2% niacinamide — the only active that makes sense for a teenager with acne

If the acne is mild to moderate (comedones, the occasional papule), niacinamide (vitamin B3) is the best first active. A study by Draelos et al. (International Journal of Dermatology, 2006) found that 4% niacinamide was comparable to 1% clindamycin (a prescription antibiotic) in reducing acne lesions after 8 weeks of use.

Why 2% and not 4–5%?

• Teenage skin is more reactive — a lower concentration minimizes the risk of irritation.
• 2% is enough to regulate sebum and deliver an anti-inflammatory effect.
• Consider higher concentrations only after consulting a dermatologist.

What you should ABSOLUTELY not use before the age of 18

This isn't a matter of opinion — it's a matter of safety:

• Retinol / retinoids — teenage skin has a fast renewal cycle (about 21 days). Retinol is unnecessary and can cause excessive flaking and photosensitivity.
• High-concentration acids (AHA >8%, BHA >2%) — a risk of damaging the skin barrier while it is still not fully mature.
• Vitamin C above 10% — L-ascorbic acid at a low pH can irritate young skin. If you want an antioxidant, a good SPF is enough.
• Mechanical scrubs with microbeads — micro-scratching skin with active acne spreads bacteria and deepens inflammation.

The TikTok problem — the algorithm doesn't know your skin

A study by Zheng et al. (Pediatric Dermatology, 2022) analyzed the 100 most popular skincare videos on TikTok. The result: only 11% contained information consistent with current dermatological guidelines. The rest promoted an excess of products, dangerous mixing of actives, or unrealistic expectations.

Teenagers approach skincare convinced that more = better. Yet dermatology is unequivocal: the younger the skin, the simpler the routine.
