The core difference
Oily skin produces excess sebum uniformly across the entire face — forehead, nose, cheeks, and chin all feel slick by midday.
Combination skin is uneven by definition: an oily T-zone paired with normal or even dry cheeks. The cheeks may feel tight while the nose looks shiny — often in the same morning.
How to identify your skin type
The most reliable test is the bare-face method:
- Wash your face with a gentle cleanser and pat dry.
- Don't apply anything. Wait 60–90 minutes.
- Blot different areas of your face with a tissue.
If oil appears from all areas — you likely have oily skin. If oil only appears from the T-zone — that's combination.
Your skin type can shift with the seasons — oilier in summer humidity, drier in winter heating.
Routine differences
For oily skin
- Foaming or gel cleanser twice daily
- Lightweight, oil-free moisturiser (don't skip it — dehydrated skin overproduces oil)
- Niacinamide serum to regulate sebum
- Clay mask 1–2 times per week
- Non-comedogenic SPF
For combination skin
- Gentle, balanced cleanser
- Lightweight moisturiser overall, with a richer one on dry areas if needed
- Multi-masking: clay on the T-zone, hydrating mask on cheeks
- Targeted serums — niacinamide for pores, hyaluronic acid for dry areas
Common mistakes
Over-stripping oily skin — using harsh cleansers or skipping moisturiser signals the skin to produce more oil. Treating combination skin as fully oily — drying out the cheeks while trying to control the T-zone makes both problems worse.
