REVOX B77 JUST Retinol 0.3% + Niacinamide 5% is an effective serum specifically designed for sensitive and dehydrated skin. It combines the anti-aging properties of Retinol and the soothing effect of Niacinamide, providing a comprehensive skincare solution. Retinol at a 0.3% concentration helps stimulate collagen production, making the skin more elastic and firmer, and significantly reducing fine lines and wrinkles. Niacinamide (Vitamin B3) at 5% strengthens the skin's protective barrier, improving moisture retention and making the skin soft and plump. Additionally, glycerin and betaine help restore the skin's moisture balance, reducing the risk of irritation, redness, and flaking. The result is a smoother, more even, and healthier appearance. For new users of Retinol, we recommend starting usage 1–2 times a week, gradually increasing the frequency as the skin adapts. To avoid irritation, the product should not be used with other retinoids or exfoliating acids.
