Cosmetics are often labeled “with provitamins”. Let‘s find out what it is. Generally speaking, provitamins are substances from which vitamins can be formed in living organisms. The most commonly used provitamins in cosmetics are retinol (vitamin A), thiamine (vitamin B1), niacinamide (vitamin B3), panthenol (vitamin B5), biotin (vitamin B7), ascorbic acid (vitamin C). Each of them benefits both the body and the skin.

Retinol (vitamin A) in cosmetics has a wide range of effects and is considered almost magical. Often used in cosmetics as slowing down the aging process. Retinol smoothes wrinkles, accelerates skin regeneration processes, evens out skin tone, lightens pigment spots, stimulates collagen production, moisturizes and strengthens the skin, improves microcirculation. When using retinol, it is necessary to apply SPF cream to the skin, and it is recommended to use it in the evenings when the sun is less active on the skin. Otherwise, there is a risk of pigment spots.

Thiamine (vitamin B1) is used not only in skin, but also in hair and scalp products. Thiamine gives the skin elasticity, reduces the signs of aging, has antioxidant properties, moisturizes, nourishes irritated, sensitive skin. Hair care products with thiamine strengthen the hair, fight against branching ends, soften the scalp.

Niacinamide strengthens the skin’s lipid barrier, reduces pigmentation, protects against free radicals and acts as a protective veil against irritating environmental factors, protects against moisture loss, fights acne, tightens pores, regulates sebum secretion. It has a positive effect on the hair as it stimulates microcirculation in the scalp.

Like niacinamide, panthenol is suitable for all skin types.

Biotin (vitamin B7) in the body is responsible for the breakdown of proteins, fats and carbohydrates, so biotin deficiency manifests itself in cracked, slippery, weak hair and various skin rashes. Biotin gives hair shine, obedience, which is why it is often used in hair care products.
