Vitamin B — an antioxidant that with consistent use can help decrease redness and help with skin texture. The most common ones found in topical skincare are vitamin B3 (niacinamide), vitamin B5 (pantothenic acid), vitamin B7 (biotin), and vitamin B12 (cobalamin).
Niacinamide (B3) is an ingredient I recommend to people with rosacea, acne, and increased redness in their the skin as well as people interested in anti-aging. B3 has emerged as a very important player in protecting skin from premature aging due to its anti-inflammatory properties.
Panthenol (B5) or pantothenic acid, works as a humectant to retain moisture and hydration of the skin, soothes and heals damaged or broken skin.
Biotin (B7) is the foundation of practically every skin, hair, and nail multivitamin in existence. Topical biotin is more likely to be found in hair growth products than skincare products, but ingestible biotin in your routine may help keep skin youthful and blemish-free.
Cobalamin (B12) helps reduce pigment; it is sometimes found in topical skincare, but it’s more commonly found in pill form (or in salmon and eggs). Vitamin B12 helps to increase cellular regeneration and encourage wound healing. When taken orally, it helps in red blood cell production, regulates pigmentation in skin and maintains healthy hair and nails.
