Advanced retinal serum designed to support smoother, firmer and more refined-looking skin.
Advanced treatment serum formulated with Retinal Liposome (2%) and Black Ginseng extract to support skin renewal, improve the appearance of fine lines, and enhance overall skin texture. The liposome technology helps deliver retinal more gently and effectively into the skin, supporting visible results while helping reduce irritation often associated with strong retinoids.
Retinal is known as one of the most effective vitamin A derivatives for helping improve skin smoothness, elasticity, and clarity. Combined with antioxidant-rich black ginseng, the formula helps support skin vitality while promoting a firmer and more refined complexion.
The lightweight serum absorbs smoothly into the skin, helping promote a more even and youthful-looking appearance over time. With consistent use, skin may appear smoother, clearer, and more balanced while supporting natural overnight skin renewal.
It is suitable for adults (20+), especially for dull, uneven, aging, and textured skin that needs advanced renewal care together with firmness and skin-smoothing support.
