SKIN1004 Retinol 0.2 Boosting Shot Ampoule 30ml Price reduction not accepted. Original price: around 4000 yen. I bought this because it was recommended on social media, but I only used it once to try it out. This serum contains retinol* and is for skin concerned about lack of firmness and signs of aging. It combines retinal and squalane to condition the skin and lead to a plump, firm impression. Centella asiatica extract processed by low-temperature vacuum extraction and panthenol, an ingredient that moisturizes and conditions the skin, are impregnated into spicules using the SML method, making it easy to penetrate the stratum corneum. The silky texture fits comfortably on the skin, supporting moisture and firmness. Perfect for those who like medicube and anua! | Retinol 0.2 Boosting Shot Ampoule 30ml | Serum Skincare Dropper Korean Cosmetics Ampoule SKIN1004 RETINOL 0.2%
