What Zinc PCA does

Helps control oil on the skin
Adds zinc to a formula
Gives a light, matte finish

Zinc PCA is made by joining zinc with pyrrolidone carboxylic acid, usually called PCA. PCA is one of the natural compounds found in skin's moisture-holding layer, which is why it suits skincare well. Zinc adds its own properties, and together they are used to help manage shine.

Formulators use zinc PCA in acne products, sunscreens, deodorants, micellar waters and cleansers. In rinse-off and wipe-off products, it helps skin feel fresh afterward. It dissolves well in water-based formulas, so it blends in without a heavy feel and leaves skin soft and non-greasy.

Good for

Suits oily or combination skin and people looking for lightweight products that feel fresh and not greasy.

Frequently asked questions

Is zinc PCA good for acne?

Zinc PCA is used in some acne products because it helps control oil, which is one factor in breakouts. It is not a prescription treatment, and it works best as one part of a routine. Results vary, so talk to a dermatologist about persistent acne.

Is zinc PCA safe for sensitive skin?

Zinc PCA is generally well tolerated and is found in many everyday products. Everyone reacts differently, though. If your skin is sensitive, patch test a new product on a small area first and stop using it if irritation appears.
