Vitamin B12 (cobalamin) is a cobalt-containing vitamin used topically as a skin-conditioning agent, with some research exploring its role in supporting skin barrier function and managing inflammatory conditions such as atopic dermatitis. In cosmetic formulations it gives products a characteristic pink-red color.
Cyanocobalamin is a synthetic form of vitamin B12 used topically in skincare, where it is studied mainly for its potential to support skin barrier function and reduce inflammation, particularly in atopic dermatitis. It also acts as a colorant due to its characteristic pink-red hue.
Allantoin is a naturally derived or synthetically produced compound used in skincare for its soothing, moisturizing, and keratolytic (skin-softening) properties. It promotes cell proliferation and helps calm irritation, commonly appearing in creams, lotions, and after-sun products.
