What's your skin type? Find out before you buy another product.

Watch how your skin behaves without products on it: how shiny it gets through the day, whether it feels tight after rinsing, and how it changes between summer and winter. The quiz asks exactly those questions and turns your answers into a skin type. If you would rather check at home, the bare-face and tissue tests work too.

Oily, combination, normal (balanced) and dry. They differ in how much oil your skin makes and where: oily skin makes more than average and shines all over, combination skin shines mainly in the T-zone, normal skin makes a moderate, even amount, and dry skin makes less than average. Sensitivity is not one of the four: the quiz reads it separately, because skin of any type can be reactive.

Oil balance, which sets your skin type: how much oil your skin makes and where. Sensitivity: how readily it reacts to products, scent and washing. Elasticity: how firm it is and where lines show. Acne: how prone it is to blackheads and breakouts. Tone: how even your color is, including dark marks, sun darkening and under-eye circles; this part also asks how light or deep your skin is. Texture: how smooth it looks and feels, and how foundation sits on it.

Your skin profile. It tells you whether your skin is oily, combination, normal or dry and gives your result on five more skin dimensions: sensitivity, elasticity, acne, tone and texture. It also lists any skin concerns your answers point to, with tips, and each dimension gets a note in plain language as you finish it. A free account saves the profile to the Skin Bliss app, which builds your routine around it.

Under five minutes. It asks 21 to 27 questions about your skin across six skin dimensions: oil balance, sensitivity, elasticity, acne, tone and texture. It asks more about a dimension only when your first answers there are mixed or unsure.

Yes. Every question is about something you already notice, like how your skin feels an hour after rinsing, so there is nothing to look up. When you know an answer, it tells the quiz about your skin. When you don't, that tells it something too: the quiz asks more about that dimension, and if most of your oil-balance answers are unsure, it leaves your skin type unsettled instead of guessing.

Yes. The quiz is free, and so is the Skin Bliss app on iOS and Android. Skin Bliss Pro is an optional upgrade inside the app.

No. You answer every question without one. A free account is what saves your skin profile and opens it in the Skin Bliss app, with no quiz to redo.

No. Every question is about something you can see in the mirror or remember from an ordinary day, like whether you wake up with a shiny face or how your skin feels an hour after rinsing with water. You won't need to know any ingredients, and the few skincare words it uses, like T-zone, are explained on the spot.

Only from your answers. For oil balance it asks whether you wake up shiny, how tight your skin feels an hour after rinsing with water, and how it changes with the seasons. If those first answers are mixed or unsure, it asks two more: how your skin would look in a close-up photo on a sunny day, and how foundation wears over a few hours.

The quiz works from how you describe your skin, so it is as accurate as your answers. It asks about things you can check, like whether your skin feels tight an hour after rinsing, and asks more when your first answers are mixed or unsure. If most of your oil-balance answers are ones like "I'm not sure", it leaves your skin type unsettled instead of guessing and lets you answer again. It uses the same questions and scoring as the Skin Bliss app. The face scanner in Skin Bliss Pro reads your skin from a photo instead.

It comes from Skin Bliss, the company behind the Skin Bliss app, and brands cannot pay for placement or a better score in Skin Bliss: its revenue comes from app subscriptions. It also looks past skin type, to five more skin dimensions that change what works on your skin.

The Skin Bliss team. Skin Bliss SIA builds the Skin Bliss app for iOS and Android in the EU, and its founders are two scientists: Dr. Maria Otworowska and Dr. Marvin Uhlmann. The quiz uses the same questions and scoring the app uses to set up your skin profile.

Yes. How much oil your skin makes shifts with age, hormones, pregnancy, medication and climate, and it tends to drop over the years. If your skin starts acting differently, it is worth taking the quiz again.

No. It is a self-assessment, not a diagnosis, and it is not medical advice. If a skin problem is painful, spreading, bleeding or not getting better, see a dermatologist or a doctor.
