Kaolin

Kaolin is one of the gentlest clay minerals used in skincare. Unlike harsher clays, kaolin on skin works delicately: it absorbs excess oil and dirt without drying out or damaging the skin.

How to use it

It's usually recommended to use kaolin masks 1-3 times a week for oily skin and less often for dry skin. To help prevent dryness, rinse off a clay mask while it’s still slightly damp. If it’s left to fully dry and crack, it may start drawing moisture from the skin instead of only absorbing excess oil.

Suitable for

Primarily oily, combination, and normal skin types.

Things to know

Pairs well with all ingredients, making it easy to include kaolin in skin care routines. However, it's not recommended for atopic skin.

FAQ

1. Is kaolin pore-clogging?

No, kaolin is considered a non-comedogenic ingredient, meaning it doesn't clog pores.

2. Can kaolin clay remove blackheads?

Yes, this is one of the main kaolin uses for skin, with one important note. Kaolin works as an adsorbent, meaning it doesn’t physically remove or “pull out” blackheads. Instead, it attracts excess oil, dirt, and dead skin cells that build up in pores. When you rinse off a kaolin mask, these impurities are removed along with it.

3. Is kaolin safe for acne-prone skin?

Yes, kaolin is often recommended for acne-prone skin. One of the key kaolin benefits for skin is its ability to absorb oil selectively, unlike more aggressive clays, such as bentonite. Kaolin helps remove excess sebum without drying out the skin or stripping away its protective lipids.
