Vitamin B12 in Skincare
Vitamin B12 in Skincare — a cobalt-containing member of the B-vitamin family, also known as cobalamin, that is essential for cell metabolism throughout the body. In skincare it appears as a conditioning ingredient and has been studied topically in the context of dry, irritated skin, and it also gives formulas a distinctive pink tint. Most of the body's vitamin B12 needs are met through diet rather than topical products.

- Its natural deep pink color can influence the appearance of creams and serums that contain it.
- Topical B12 has been explored in research on dry, sensitive, and irritation-prone skin.
- Dietary intake, not topical application, is the primary way the body maintains adequate B12 levels.
Frequently asked
Why do some vitamin B12 products look pink?
Cobalamin is naturally a deep red-pink pigment, so formulas containing meaningful amounts often take on a pink hue.
Can topical vitamin B12 replace dietary B12?
No; the body relies on dietary or supplemental B12 for its systemic needs, and topical use is intended for skin conditioning rather than nutrition.
