Melano CC Vitamin C Brightening Essence 20ml

Melano CC Vitamin C Brightening Essence 20ml is a concentrated serum for oily and acne-prone skin with post-acne marks, dark spots, and sun-triggered pigmentation — using pure L-Ascorbic Acid (the most active and clinically studied form of Vitamin C) housed in an aluminium tube that blocks light and air, preventing the oxidation that degrades most Vitamin C serums before they are finished. It is certified as a quasi-drug (医薬部外品) under Japanese pharmaceutical standards.

• Pure L-Ascorbic Acid — the most potent and bioavailable form of Vitamin C, directly inhibits melanin production
• Vitamin E (Tocopheryl Acetate) — works synergistically with Vitamin C and improves skin repair
• Dipotassium Glycyrrhizate — anti-inflammatory active derived from licorice that prevents acne-triggered pigmentation
• Isopropyl Methylphenol — antibacterial active that prevents new acne formation and secondary marks
• Aluminium tube with precision drop nozzle — blocks light and air to maintain L-Ascorbic Acid potency from first to last drop
• 20ml — approximately 60–90 days at 4–5 drops daily; a small amount covers the full face

How it works: L-Ascorbic Acid inhibits tyrosinase — the enzyme that converts tyrosine into melanin — at the melanocyte level. It also reduces existing oxidised melanin, which is why consistent use brightens existing marks while preventing new ones. The aluminium tube is not cosmetic; L-Ascorbic Acid degrades rapidly when exposed to oxygen and UV, turning yellow and losing efficacy. The airtight tube maintains consistent active concentration from the first drop to the last in a way that glass droppers and open pumps cannot.

Melano CC Standard Essence vs Melano CC Premium Essence: The standard Essence (this product) contains pure L-Ascorbic Acid as the sole Vitamin C source — effective for general brightening, mild post-acne marks, and preventive daily use. The Premium Essence adds three additional Vitamin C derivatives for a multi-angle, sustained-release approach — suited for stubborn older pigmentation that has not responded to lighter treatments, or for oily skin where sebum control alongside brightening is a priority.

Known in Japan as メラノCC 薬用しみ対策 美容液 20ml.
