How to Determine Your Skin Type

How to Determine Your Skin Type — the process of identifying how your skin behaves — typically classed as oily, dry, combination, normal or sensitive — based on oil production, hydration and reactivity. Knowing your type guides which cleansers, moisturisers and actives will suit you.

Key points

  • The bare-face test: cleanse, wait an hour with nothing applied, then observe — shine across the face suggests oily; tightness suggests dry; shine only in the T-zone suggests combination.
  • Skin type (genetic tendency) is different from skin condition (temporary states like dehydration or irritation).
  • Sensitivity is a separate axis — any skin type can also be sensitive.
  • Skin type can shift with age, climate, hormones and season, so it's worth reassessing periodically.

Frequently asked

What is the difference between dry and dehydrated skin?

Dry skin lacks oil (a skin type); dehydrated skin lacks water (a temporary condition that any type can experience). They are treated differently.

Can skin type change over time?

Yes. Hormones, ageing, medication and climate can all shift how much oil and water your skin holds, so your type is not necessarily fixed for life.
