How to Use OnSkin

1. Let’s Get to Know Your Skin

First, answer a few questions about your skin type and goals. That way, we can flag ingredients to avoid and ones that work well for you.

2. Snap, Scan, or Type In a Product

Simply take a photo of a cosmetic product, scan its barcode, or look it up in the app. That’s where science comes in.

3. See If It’s Safe for You

You’ll see one of four safety scores: Excellent, Good, Not great, or Bad.

“Bad” means certain ingredients may pose health risks, such as allergic reactions or endocrine disruption. “Excellent” means the product is unlikely to pose health risks. All the scores are 100% unbiased.

4. Check If It’s a Match for Your Skin

You’ll also learn if a product is a match, a potential match, or not a match for your skin—and why. This assessment is based on the product’s ingredients, their effects, and your skin survey.

5. Find Better Alternatives

Did your product’s safety score turn out to be poor? OnSkin will suggest safer alternatives from the same category.

You might just find your new go-to product.
