Cos De BAHA Azelaic Acid 10% Serum

The Cos De BAHA Azelaic Acid 10% Serum 30ml is a serum with 10% azelaic acid, as the name says. Azelaic acid is a well-known ingredient often chosen by people with blemish-prone skin, redness or uneven-looking tone.

It's a good fit for oily, combination and acne-prone skin.

How to use: apply a thin layer to clean, dry skin once a day to start, then increase to twice daily if your skin tolerates it. Follow with moisturiser. A mild tingle can be normal at first.

Wear sunscreen during the day and patch test before first use. For persistent acne or rosacea-like redness, consult a dermatologist.
