Anua Houttuynia Cordata 77 B3 Zinc Trouble Serum

What is this product?

A trouble-care serum built on 77% heartleaf water with 5% niacinamide and 1% zinc PCA, aimed at blemish-prone skin and brightening of tone and dark spots, with a fragrance-free, no-drying-alcohol ingredient list.

What makes it different?

The formula prints exact concentrations for its three headline actives: heartleaf water at 77%, niacinamide at 5%, and zinc PCA at 1%, with heartleaf vesicles at 1.5ppb also stated. It holds a government-reviewed whitening functional cosmetic registration. The screen found no fragrance, no essential oils and no drying alcohols, which suits sensitive or reactive skin.
