Vitamin C

Vitamin C has been attracting cosmetologists' attention for a long time, and the studies in recent years confirm that it plays an important role in maintaining healthy and beautiful skin. 
It participates in all processes that run in the skin - growth, restoration of connective tissue, protection against harmful effects of the environment, wound healing, collagen synthesis, and it prevents premature skin aging. It actively inhibits melanin production, thereby reducing the formation of pigmented spots and freckles. It is an excellent skin lightener. 
Vitamin C is a powerful antioxidant that binds free radicals which are formed under the influence of external factors and as a result of physiological processes within the body. 
It possesses unique protective properties. Its content in the sun-damaged skin is significantly less than in normal skin, as it is consumed to prevent and neutralize the harmful effects of sunlight. 
When it runs out of Vitamin C, the skin loses its smoothness, elasticity and youthful appearance. 
In its pure form, however, Vitamin C is very unstable. It begins to lose its potency once it is exposed to day light, air and high temperatures. It dissolves readily in water, but is easily oxidized in aqueous solution in the presence of air and light. Therefore using it as an ingredient of skin care products has been a problem for a long time. The different forms of Vitamin C that were used before, were either unstable or less effective. Today, as a result of scientific research and new technologies, a new form of ascorbic acid is available that is fat-soluble. This discovery enables the successful usage of Vitamin C as an ingredient of modern cosmetic products by retaining its potency throughout the entire shelf life of cosmetic products. The series of face care products with Vitamin C under the trade mark REFAN contains a fat-soluble form of Vitamin C with the following properties:
. very good absorption through the skin
· inhibition of intracellular tyrosinase activity and melanogenesis (skin lightening)
· reduction of UV-induced DNA damage of the cell (UV protection / anti-stress)
· prevention of lipid peroxidation and premature skin aging (antioxidant)
· stimulation of collagen synthesis and protection of collagen levels (anti-aging)

Day cream protects skin against UV rays and, preventing it from free radical formation, helps to prevent premature skin aging.

Night cream regenerates skin during the night and helps prevent the formation of wrinkles.

Face serum has proven skin-lightening properties. If applied under the day and night cream, as well as if used independently, it reduces skin pigmentation . Due to its natural ingredients, it has not only skin lightening effect, but also skin regeneration properties.
