Our take
Is Vitamin B12 a Good Ingredient?
It rates Fair because its primary role here is coloration, and topical skincare benefits beyond that aren't well substantiated. It can also be unstable to light and pH, may cause temporary staining, and rare sensitivity is possible, which limits the rating.
What it does
Skin Benefits
Imparts a rosy tint that can brighten the look of dull complexions. Any skincare benefits beyond color are not well supported by topical research.
Where you'll find it
Uses in Skincare & Cosmetics
Used in pink-toned gels, lotions, and sheet masks for a blush hue or color-correcting effect. Also appears in lip treatments and eye creams to achieve a distinctive magenta shade.
Before you use it
Safety
Generally considered low risk at cosmetic levels, but it may stain skin, nails, and fabrics and can shift color with light or pH. Mild irritation is uncommon but possible in sensitive users; patch testing is prudent.
