Anua

The Niacinamide 10% + TXA 4% Serum is the product that built the brand's reputation, specifically for dark spots and post-acne marks that respond slowly to niacinamide alone.

Heartleaf (Houttuynia Cordata) is a calming, anti-inflammatory plant extract — Anua's core ingredient for sensitive, reactive, or acne-prone skin, used across cleansers, toners, and moisturizers.

Heartleaf if sensitivity, redness, or breakouts are the main concern. Rice + Ceramide if the priority is glow and barrier repair for dry or dull skin without significant irritation.

Yes, though most people apply them at different times — niacinamide serum in the morning under sunscreen, retinol at night, since retinol increases sun sensitivity.
