Without daily SPF, UV light breaks vitamin C down, drives new dark spots and speeds collagen loss — so your serum is left fighting an uphill battle.

It works at a comfortable pH 5.5 instead of the low pH of L-ascorbic acid, so it delivers vitamin C benefits without the tingle — ideal for sensitive skin.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWho should choose C15 MAP over the L-ascorbic serums?\u003c\/strong\u003e\u003cbr\u003eChoose C15 MAP if L-ascorbic acid serums sting, if you have sensitive or easily-irritated skin, or if you simply prefer a tingle-free vitamin C. If your skin tolerates stronger actives, our C10 or C20 offer a higher-strength L-ascorbic dose.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill it still brighten if it's so gentle?\u003c\/strong\u003e\u003cbr\u003eYes — MAP is a well-studied vitamin C derivative that supports brightening and antioxidant defense. It simply works more gradually and gently than high-strength L-ascorbic acid.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow should I store it?\u003c\/strong\u003e\u003cbr\u003eKeep the cap closed and store in a cool, dark place; refrigerate unopened bottles. MAP is more stable than L-ascorbic acid, but fresh is still best — use opened bottles within a few months.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat if it doesn't work for me?\u003c\/strong\u003e\u003cbr\u003eYou're covered by our 30-day money-back guarantee.
