Hydroxypinacolone Retinoate (HPR) is a next-generation gentle Vitamin A that takes effect directly. Targeting pigmentation and dark spots, clinical data shows that using a formulation containing 2% AC-HPR-S10 (containing 0.2% active HPR) for 4 consecutive weeks can significantly reduce the area of dark spots and enhance skin brightness (L-value), achieving an even and radiant complexion. In terms of UV protection, HPR has been proven to be non-phototoxic. It can effectively inhibit UV-induced ROS (Reactive Oxygen Species) pathways, reducing free radical damage and collagen degradation. When combined with 0.2% Glucosylrutin (GR), it can also slow down HPR degradation by 3%, providing you with a safe and efficient scientific solution for spot removal, brightening, and anti-photoaging.

Hydroxypinacolone Retinoate (HPR) is a gentle yet highly effective new-generation anti-aging ingredient. It can directly bind to receptors to exert its effects without conversion within the skin, significantly reducing the risk of redness and peeling associated with traditional retinol.

​Ascorbyl Tetraisopalmitate (referred to as VcOS) is a highly stable, oil-soluble Vitamin C derivative. It overcomes the disadvantage of traditional water-soluble Vitamin C being easily inactivated, remaining stable against light and heat, and offering excellent transdermal absorption: experimental data show that at a concentration of 20μM, its intracellular content of free Vitamin C is 50.92 times that of ordinary Vitamin C. Its core benefits are efficient whitening and anti-oxidation. Experiments show that 0.2% VcOS can reduce melanin production by more than 80%; clinical tests with a 2% addition level show it can significantly reduce the skin's melanin index (melanin index(MI) decreased from 220 to 183). VcOS is friendly to sensitive skin, with a recommended formula addition level of 0.1%-5.0% (pH < 6). It is widely used in cosmetics such as face creams, sunscreens, and essences.
