Vitamin B2 or Riboflavin is hidrosoluble; its deficiency causes an excessive excretion of sebum that leads to the appearance of an oily skin and acne.
It promotes the cellular respiration; it falls into the category of regulatory products of Seborrhea. It promotes the dissolution of fat.
Niacinamide or Vitamin B3
The Vitamin B3 could be found in several different ways, all of which can be identified as niacin.
This vitamin appears in the literature as vitamin PP (prevention of pellagra) and is a stable vitamin, with low molecular weight, therefore penetrates easily into the skin.
It is very well tolerated by the skin, does not induce irritation, redness, itching, burning or itching-resistance to external agents.
The application of vitamin B3 in the skin has proven to be more resistant to the destructive agents of the barrier, as detergents and aggressors environmental-staining of the skin.
This translates into less irritation and redness and contributes to produce visible benefits in color in clinical tests valued as red spots, facial; irritation was reduced through the daily use of topical vitamin B3.
Chronic treatment with vitamin B3 could have an effect on the hyper pigmented skin. Another benefit of vitamin B3 topical in coloration, is the reduction of the citrine or yellow discoloration of the skin. Reduction of the yellowing mechanism is due to the antioxidant effect of this vitamin.
Bad texture of skin aging in the area of the cheeks is due to two factors: an increase in pore size and an irregular appearance.
Vitamin B3 when used for long periods of time, improves skin texture, since it decreases sebum production resulting in decrease in the size of the pore.
Facial wrinkles are reduced using this vitamin, due to increased collagen production and the decrease of the dermal glycosaminoglycan excess production, since for the normal functioning and structure of dermal matrix is required a small amount of glycosaminoglycan.
The Vitamin B3 and its relationship with other B vitamins
The Nicotinic Acid is a derivative of pyridine (an organic base) somewhat simpler than pyridoxine (vitamin B6).
The relationship between vitamins is especially evident when you look at this vitamin.
Vitamin B3 can be synthesized from the essential amino acid tryptophan, when thiamine (vitamin B1), Pyridoxine (vitamin B6) and Riboflavin (vitamin B2), act as coenzymes.

· It plays a key role in the production and use of energy.
· Assistance to the respiration of cells contributing to the transport of hydrogen.
· It promotes the maintenance of normal levels of cholesterol in conjunction with a low fat diet.
· It is imperative in the deamination of amino acids and in the synthesis of fatty acids and in the beta oxidation.
· It has am expanded action of blood capillaries
· It acts in the central and peripheral circulation disorders
· It behaves as exciting of motility gastric and digestive secretions
· It is a regulator of the nervous system
· It is a stimulant of the formation of the blood pigment, so it can be an adjuvant in the treatment of the anemia
