Protect your skin from viral beauty trends.
COSMO-Check is a safety app that analyzes skincare trends, ingredient combos, and dermatologist input to warn you before your skin gets burned, irritated, or damaged.
COSMO-Risk Score: 92 / 100 (High damage potential)
Most common issues: chemical burns, hyperpigmentation, barrier breakdown. Dermatologist consensus: “Avoid this trend.”
Why COSMO-Check?
Viral skincare hacks spread faster than good science. Dermatologists are seeing more burns, pigment problems, and barrier damage from DIY trends — and there’s no simple way for people to check if a trend is safe for their skin. COSMO-Check is here to change that.
Viral doesn’t mean safe
People copy beauty trends from TikTok and Instagram without knowing the risk. Aesthetic filters hide real skin damage until it’s too late.
Derm visits after the damage
Dermatologists often only see patients after burns, peeling, and dark marks have already appeared. Most of this harm was preventable.
Safety checks before you try it
COSMO-Check gives you a clear risk score, expert insights, and safer alternatives before you put anything on your skin.
How COSMO-Check works
1. Search a trend or routine
Type in a viral hack (“microneedling with vitamin C”, “slugging, “skin cycling”) or paste a product combo you’re thinking of using.
2. We analyze risk
Our engine combines ingredient data, dermatology literature, real-world harm reports, and expert reviews to compute a COSMO-Risk Score tailored to your skin profile.
3. You get a clear answer
See how risky the trend is, what could go wrong, what dermatologists say, and which safer alternatives you can try instead.
What COSMO-Check does for you
A calm, science-driven guide in a world of loud beauty advice. COSMO-Check is built to be useful on day one, even before the full app launches.
Trend Safety Scanner
Search any trend or hack and see a COSMO-Risk Score, a simple safety label, and a breakdown of the most common skin issues linked to it.
Ingredient Interaction Checker
Enter products or ingredients and instantly see if the combo is likely to irritate, over-exfoliate, or increase sun sensitivity.
Personalized Skin Profile
Tell us your skin type, tone, and sensitivities so we can highlight trends that are especially risky (or safe) for your skin.
Safe Alternatives
Instead of just “don’t do this,” COSMO-Check suggests gentler, evidence-based options you can discuss with your dermatologist or try yourself.
