The Science Behind A4

Azelaic Acid 10%

A multifunctional skincare ingredient known for its ability to help improve blemish-prone skin, uneven texture, redness, and the appearance of discoloration.

Alpha Arbutin 2%

A targeted brightening ingredient that helps reduce the appearance of excess pigmentation and promote a more even-looking complexion.

Niacinamide 3%

Vitamin B3 helps support the skin barrier, improve uneven skin tone, and regulate the appearance of excess oil.

Licorice Root Extract 2%

A botanical ingredient valued for its soothing and antioxidant properties, helping promote a calmer, brighter-looking complexion.

Why Azelaic Acid + Alpha Arbutin?

Two powerful actives. Two complementary approaches. One targeted formula.

Uneven skin tone is rarely caused by a single factor. Blemishes, inflammation, and excess melanin production can all contribute to persistent dark spots and post-acne marks.

That’s why we brought together 10% Azelaic Acid and 2% Alpha Arbutin in A4 Gel.

Azelaic Acid helps address blemishes, visible redness, and uneven texture while also targeting excess pigmentation.

Alpha Arbutin complements this action by helping inhibit tyrosinase, an enzyme involved in melanin production, to reduce the appearance of dark spots and discoloration.

Together, they offer a thoughtful, multi-targeted approach to achieving clearer, smoother, and more even-looking skin.

Enhanced with Niacinamide and Licorice Root, the formula also supports the skin barrier and helps promote a calmer, brighter-looking complexion.

Because effective skincare isn’t about adding more ingredients. It’s about choosing ingredients that work with purpose.
