Nine less A-Control 10% Azelaic Acid Serum

Nine Less A-Control 10% Azelaic Acid Serum 30ml is a K-beauty serum with 10% azelaic acid, as the name says. Azelaic acid is a popular ingredient for blemish-prone skin and uneven-looking tone.

It's suited to oily, combination and acne-prone skin.

• Apply a thin layer to clean, dry skin.
• Start once a day, then increase if your skin tolerates it.
• Follow with moisturiser.

Mild tingling can happen at first. Use sunscreen during the day and patch test before first use. For persistent acne or redness, consult a dermatologist. Avoid using it at the same time as other strong acids or exfoliants until you know how your skin reacts.
