Enriched with 0.1% retina, the advanced form of retinol, combined with A-Shot, designed to penetrate directly into pores and improve absorption, delivers retina deep into the skin to combat wrinkles and enlarged pores and promote smoother and firmer skin. Innovative skin care product with liposomized retinal and matrixyl that treats skin problems such as wrinkles, uneven texture and enlarged pores. A refined micro-particle ingredient, 16 times thinner than pores, is designed to penetrate directly into the pores and improve the absorption of active ingredients. Through high-purity separation and refinement, the particles are evenly dimensioned, reducing skin irritation. Enriched with high concentrations of retina, a more advanced form than retinol, and matrixyl, just a single drop provides deep elasticity to problem areas such as wrinkles or enlarged pores. If you are new to using retinol or retina, apply it every other night for the first two weeks. Apply a small amount to the target areas. If irritation occurs, reduce the amount and frequency and use a moisturizer with soothing ingredients. The retina may cause your skin to appear slightly yellow after application. It is completely washed off with cleaning. Avoid contact with eyes and wash your hands thoroughly after use. This product is only suitable for night use, and sunscreen must be applied the next day. Applying too much at once can cause skin irritation.
