Vitamins are an organic compound and an essential nutrient that an organism requires in limited quantities. An organic chemical compound (or a related group of compounds) is called a "vitamin" when the body is unable to synthesize that compound in sufficient quantity and therefore must obtain it through food; thus, the term "vitamin" is conditioned by circumstances and the particular organism.

VITAMIN A: At the dermis level, vitamin A acts, on the other hand, causing an increase in collagen production, with a consequent improvement in the "support structure" that contributes to giving tone and elasticity to the skin. Source
VITAMIN D: Regulates the proliferation of keratinocytes by helping cell renewal. Regulates and protects cell structures during the life of the cells themselves. It generates a re-epithelializing and revascularizing activity, fundamental in facilitating the healing of skin ulcers and lesions of various kinds.
VITAMIN E: Improves the condition of the skin, acting to protect the lipids present in the cell membranes, maintaining excellent hydration. It also has a positive anti-inflammatory and defense action against aging.
VITAMIN F: Vitamin F, keeping the cell membrane fluid, nourishes the skin making it soft and elastic and stimulates rapid cell regeneration.


Vitamins, in the cosmetic field, are particularly useful in the prevention and treatment of numerous imperfections. They are essential compounds for human life, which in principle are not synthesized directly by the body and therefore must be taken through the diet. One way to classify them is according to their solubility:


Vitamin B1 (thiamine)
Vitamin B2 (riboflavin)
Vitamin B3 (niacin)
Vitamin B5 (pantothenic acid)
Vitamin B6 (pyridoxine)
Vitamin B8 or Vitamin H (biotin)
Vitamin B9 or Vitamin M (folic acid)
Vitamin B12 (cobalamin)
Vitamin C (ascorbic acid)


Vitamin A (retinol and analogues)
Vitamin D (ergocalciferol D2 and cholecalciferol D3)
Vitamin E (tocopherol)
Vitamin K (naphthoquinone derivatives)
EFA (essential fatty acids)
Vitamin F

Vitamins are a great resource for the skin not only when taken orally, through diet or with supplements, but also when carried with enriched creams! In fact, the effects are remarkable, but only from some of the vitamins that we commonly know.

In the cosmetic field the most used vitamins with an interesting action, aimed at the prevention of oxidative phenomena, are vitamin A, C, E and some of the B vitamins.

The first to be used for its effects on the dermis was undoubtedly vitamin A, present to date in esterified forms of retynol palmitate and acetate, however the most popular and used vitamins are undoubtedly vitamin C and vitamin E. That is, we are talking about ascorbic acid and tocopherol, also in these cases not pure, but esterified to allow a better resistance in cosmetics and to act in an active way on the dermis (ascorbyl palmitate, tocopherol acetate).

Vitamin C is known not only for its antioxidant properties, but also for its photo-protective, lightening and capillary protective properties. A true elixir of beauty if properly formulated, as the real limitation of its use lies in its high chemical instability, which makes it particularly sensitive to light, high temperatures and causes easy deactivation.

The same is true for vitamin E, commonly known as tocopherol, which is active on the dermis in massive form thanks to its great antioxidant power that counteracts the damage of free radicals and therefore skin aging. Its mechanism of action is not completely known, however its high specificity for skin tissue has been demonstrated. Also in this case, however, the product must be used in esterified and modified forms to preserve its stability.

So pay attention to the labels and what you are told, a pure product would not be functional as it would lose its properties even before being packaged, instead, acetylated or esterified forms manage to preserve their integrity and make them active once they reach the dermis.
