Description

Heavy creams sit on top. Thin serums don't do enough. If your skin is losing firmness and you want results without the weight, you need something smarter.

The EGF NAD+ Firming Serum is a lightweight, fast-absorbing formula powered by NAD+, EGF peptide technology, collagen extract, niacinamide, hyaluronic acid, and berry antioxidants. These are the same biotechnology-inspired actives trending in Korean dermatology. The watery texture absorbs in seconds and layers easily under moisturizer or makeup.

Firmer, smoother, more radiant-looking skin from forehead to neck.

One serum that targets multiple signs of aging without feeling heavy.
