"How do I know my skin type?" is the first question of every skincare journey — and getting it wrong is why so many routines fail. Products built for oily skin strip dry skin; rich creams for dry skin clog oily skin. Here's the dermatologist-style way to test your skin type at home in under an hour, free.
Cleanse, apply nothing, wait 30–60 minutes. Shiny everywhere = oily. Tight, dull, or flaky = dry. Shiny forehead/nose with normal cheeks = combination. Easily stinging or flushing = sensitive. Comfortable and even = normal.
The bare-face test (the only test you need)
Dermatologists call it the "watch and wait" method, and it beats any quiz:
- Step 1: Wash your face with a gentle, fragrance-free cleanser.
- Step 2: Pat dry and apply nothing — no toner, no moisturizer.
- Step 3: Wait 30–60 minutes and look closely in natural light.
How your skin behaves with zero products on it is your true baseline. Everything you normally feel after applying products is the products talking, not your skin.
The five skin types, decoded
Oily: visible shine across forehead, nose, cheeks and chin within the hour; enlarged-looking pores; makeup slides off by midday.
Dry: feels tight after cleansing; flaky patches, dullness, fine lines look more pronounced; absorbs moisturizer instantly.
Combination: the most common type — an oily T-zone (forehead, nose, chin) while cheeks stay normal or dry. You need zone-aware care, not one heavy cream everywhere.
Sensitive: stings with new products, flushes with heat or wind, reacts to fragrance. Sensitivity overlaps any other type — you can be oily and sensitive.
Normal: balanced — no persistent shine, no tightness, rarely reactive. Your job is protection, not correction.
Your skin type is not permanent
The biggest myth in skincare is that you test once at 19 and you're "oily forever." Skin shifts with seasons (oilier in humid summers, drier in heated winters), hormones (oil production swings across the menstrual cycle — see our guide on breakouts before your period), stress, climate, and age. A routine that worked in July can fail in January for no other reason than your skin type quietly moved.
The smarter way: track it, don't guess it
A one-time bathroom test tells you today's answer. Daily tracking tells you the trend — and the trend is what your routine should follow. Rosee Skin reads hydration, shine, and texture from a daily face scan and watches how they move across weeks and hormonal phases. The analysis runs entirely on your device — your photo never leaves your phone — and if a scan can't be read confidently, Rosee says "not enough data" instead of inventing a number.
