How to find your skin type, and why it can change
Wash, wait, then look: a simple way to find your skin type before buying Korean skincare, why it shifts with age and season, and what all skin types means.
To find your skin type, wash with a gentle cleanser, put nothing on, and look again about half an hour later. Shiny all over means oily, tight and flaky means dry, shiny in the middle but tight on the cheeks means combination, and comfortable everywhere means normal. Check again when the season changes, because the answer can move.
What are the skin types?
Four, based on how much oil your skin makes and how well it holds water.
- Oily: shine across the forehead, nose, chin and cheeks, often by midday.
- Dry: feels tight after washing, with flaky patches, especially on the cheeks.
- Combination: oily through the T-zone (forehead, nose, chin) while the cheeks feel normal or tight.
- Normal: neither shiny nor tight for most of the day.
Sensitive isn't a fifth type so much as a trait that sits on top of any of the four. If products often sting, burn or turn you red, that's worth knowing whatever your type. We wrote about building a routine around it in the sensitive skin routine.
How do you test your skin type at home?
The bare-face test takes one wash and some patience.
- Wash with a gentle cleanser and pat dry.
- Put nothing on: no toner, no moisturizer, no sunscreen.
- Wait about 30 minutes and stay out of heat and wind.
- Look in the mirror and touch your forehead, nose and cheeks.
If you want a second opinion, press a blotting paper or a clean tissue on each area. Oil shows up as a see-through mark. Lots of marks everywhere points to oily skin, marks only on the T-zone to combination, and almost none with tightness to dry.
Do the test on an ordinary day. Right after exfoliating, a new product or a day in the sun, the skin tells you about that day more than about its type.
Can you trust how your skin feels?
Partly. How oily your skin feels and how oily it measures don't always line up.
A study of 300 women in China (Wu and colleagues, 2013) compared how oily each woman said her skin was with the oil measured on it. The two matched fairly well in younger women, and the match got weaker with age. So the test above is a good start, not a lab result, and trusting the feel alone gets less reliable with age.
Oil and water are also separate things. Another study, in 62 women in Thailand, found that skin carrying more surface oil tended to hold less water in its top layer, not more. Korean labels have a word for that mix: 수부지, oily but dehydrated. 30 products we checked used it in their ad lines. It describes something real, but no study we found defines it as its own skin type or tests products against it.
Why does your skin type change?
Because oil and water change with your surroundings and your age.
- Season: warmth raises how much oil reaches the surface. A face that's combination in summer can act dry in winter.
- Age: oil output rises through the teens and tends to drop later on, gradually for women after menopause.
- What you use: a harsh cleanser or frequent exfoliating can leave skin tight and irritated, which is easy to mistake for a dry type.
That's why it's worth repeating the test a couple of times a year, rather than buying for a type you worked out once.
What does "for all skin types" mean on a Korean label?
That anyone can use it, not that it was made for you. Among the Korean products we checked, 90 had ad lines saying they suit all skin types. They were spread across cleansers, toners, creams and sunscreens.
Treat the phrase as neutral. The ingredient list and the texture tell you more about whether a cream will feel heavy on oily skin or too light on dry skin.
Where do you go from here?
Once you know your type, start with the five steps in our starter routine and adjust the moisturizer step to your type.
- Oily: a routine for oily skin and gel cream or lotion for oily skin
- Dry: a routine for dry skin
- Combination: a routine for combination skin
Common questions
Can I be oily and dry at the same time?
Yes, in two ways. Combination skin is oily in some areas and dry in others. And a face can make plenty of oil while its top layer is short on water, the mix Korean labels call 수부지. Either way, a light gel moisturizer is one option before skipping moisturizer altogether.
Do I need different products for summer and winter?
Often just a different moisturizer. Cleanser, toner and sunscreen can stay the same, with a lighter layer in summer and a richer one in winter.
Should I see a dermatologist to find my type?
Not for type alone. See one if your skin keeps breaking out, stays red, itches or flakes no matter what you use.
If you've done the test and still aren't sure, tell us what your skin did and send a photo of the label or the product name you're using now. We'll read the ingredient list for you.
