{"product_id":"dr-althea-gentle-vitamin-c-serum","title":"Dr.Althea Gentle Vitamin C Serum, 30 ml","description":"\u003cp\u003eA water-based serum, never sticky, that absorbs within seconds without leaving a film or yellowing over time — a texture designed for sensitive skin that usually shies away from vitamin C.\u003c\/p\u003e\n\u003ch2\u003eWhy we love it\u003c\/h2\u003e\n\u003cp\u003eThe active ingredient chosen is 3-O-ethyl ascorbic acid, a stable derivative of vitamin C: it avoids the instability to air and light of pure L-ascorbic acid, at the cost of a skin conversion into active ascorbic acid that remains partial and gradual — it should not be presented as equivalent in strength to a 15-20% pure acid. It is combined with niacinamide and sea buckthorn fruit water (Hippophae rhamnoides, 20%), naturally rich in vitamin C, without this being a dose of pure vitamin C. Dr.Althea built its reputation on minimalist formulas (fewer than 20 ingredients) developed with Korean dermatologists; this serum applies the same logic to radiance rather than soothing.\u003c\/p\u003e\n\u003ch2\u003eHow to use it\u003c\/h2\u003e\n\u003cp\u003eIn the morning, after toner, apply 2 to 3 drops over the whole face before moisturizer. Daily sun protection is still recommended to preserve the radiance achieved. Niacinamide and vitamin C layer without any problem; however, avoid applying it in the same layer as a copper peptide.\u003c\/p\u003e\n\u003ch2\u003eWho it's for\u003c\/h2\u003e\n\u003cp\u003eSensitive skin that has never tolerated pure ascorbic acid, dull skin or skin marked by light spots, and any skin that wants a vitamin C for consistency rather than shock.
