What are the common misunderstandings about caring for combination skin?
This answer is a draft. It stays unpublished until legal review and source verification are complete.
Combination skin — "my T-zone shines but my cheeks are dry" — is often described as the most common skin type among Japanese people, and "which product should I choose?" is a classic question in expat forums too. Here we set out the skin-type classification and the Japanese idea of caring for each area of the face separately.
Skin types (customary classification)
| Skin type | Water | Sebum | Features |
|---|---|---|---|
| Normal | High | Moderate | Few problems |
| Dry | Low | Low | Flakiness, tightness |
| Oily | High | High | Shine, visible pores |
| Combination | Differs by area (cheeks lower) | High in the T-zone | Shine and dryness at the same time |
| "Inner dry" (customary term) | Low | High | Described as skin making up for dryness with sebum |
- Skin types are not medical diagnoses; they are customary terms used by the industry and by consumers. They change with season, age, sleep and hormones.
- One way to tell: after washing your face, wait 10–15 minutes with nothing on. If your cheeks feel tight while your T-zone shines, you tend towards combination skin (see our article on identifying your skin type).
- Cosmetic claims are limited to the 56 items, so wording like "balances sebum" is restricted, for a cosmetic, to the range of "washes away sebum", "tightens the skin" and so on.
[Verify] The description of skin types is based on general industry and dermatology descriptions. Check the 56 items against MHLW notice Yakushoku-hatsu 0721 No. 1.
Misunderstanding 1｜A "combination skin" product over the whole face solves it
"For combination skin" is an averaged formulation. Dividing by area (light on the T-zone, richer on the cheeks) matches the reality better.
Misunderstanding 2｜Shiny areas need no moisturiser
The T-zone needs water too. Use a low-oil moisturiser (a gel, or a small amount of emulsion — 乳液, nyūeki, a light milky moisturiser). It is sometimes explained that with nothing applied, the skin tends to produce sebum to make up for the dryness.
Misunderstanding 3｜Pile cream thickly on dry cheeks
Thick layers can cause blocked pores and spots. Adjust the amount instead: thin layers, or cream at night only.
Misunderstanding 4｜Combination skin can be fixed
Skin type is the result of your constitution, the season and your lifestyle, not something to be "fixed". The aim is to match your care to the condition at the time. If acne or inflammation keeps coming back, see a dermatologist (a dermatology clinic is covered by Japanese health insurance).
Misunderstanding 5｜Wash the whole face with the same force
Put the foam on the oily T-zone first, and do the cheeks last and briefly — varying the washing time by area is the method shared among people living in Japan. Hot water dries the whole face.
