Purito Seoul - Retinol Retinal 2000 NAD+ Serum 30ml
Hurry up, only 5 items left in stock.
An anti-aging serum with two forms of vitamin A plus NAD+ for visibly smoother, firmer and more radiant skin. The formula combines 1,000 ppm retinol, 1,000 ppm retinal and 100 ppm NAD+. Retinal is one step closer to the active form of vitamin A than retinol, so it works faster. Retinol works at a slower, gentler pace for long-term skin renewal. Using both together is more balanced than a high dose of a single retinoid, which helps reduce the risk of irritation. NAD+ supports the skin's natural energy and renewal.
The serum has a dual-phase texture. Shaking the bottle mixes the active ingredients right before use. Ceramide NP, niacinamide, centella asiatica and adenosine strengthen the skin barrier, even out dull skin tone and keep skin hydrated. The light, silky texture absorbs quickly without feeling heavy or greasy. It fits easily into your evening routine.
