MEDIHEAL Vitamin C Essential Mask 1PC is a signature 'gentle brightening' mask under the MEDIHEAL brand, with two core advantages:?'stable Vitamin C derivative complex' and 'brightening + moisturizing + soothing triple protection'.
The 'Vitamin C Essential' in the name highlights its key active ingredient�� a?stable Vitamin C derivative complex?(typically including Ascorbyl Glucoside, Magnesium Ascorbyl Phosphate, etc.). Unlike pure Vitamin C (L-ascorbic acid), which is easily oxidized and irritating, these derivatives are stable in air and water, and mild to the skin. They convert to active Vitamin C in the skin, effectively inhibiting tyrosinase activity (a key enzyme in melanin production), blocking melanin transfer to the skin surface, and reducing dullness and dark spots.
To solve the common problem of 'dryness after brightening' with traditional Vitamin C products, this mask adds a multi-moisturizing complex (hyaluronic acid, glycerin) and soothing ingredients (centella asiatica extract, panthenol). The moisturizing ingredients replenish deep skin moisture, ensuring brightening does not cause dryness; the soothing ingredients reduce potential irritation from Vitamin C, making it suitable for mild sensitive skin.
Each sheet contains 25-30ml of concentrated Vitamin C essence, with a light, non-greasy texture that is easily absorbed. The mask paper is made of MEDIHEAL��s patented ultra-thin cellulose material, which fits closely to facial contours (even around the nose, eyes, and jawline) to maximize essence absorption. The 1PC (single-sheet) packaging is hygienic and portable, and the opaque design protects the Vitamin C derivatives from light oxidation. It is positioned as a 'daily gentle brightening mask' for most skin types, meeting the needs of long-term dullness improvement and safe brightening.
