Oily skin is a headache for people suffering from it. Localized on the face, the scalp, the cleavage, the upper back, it affects the parts of the body the most exposed to view and the most esthetically attractive. Oily skin is as unaesthetic as possible. It is visible, is noticed and is often felt as a terrible social obstacle. It is very difficult to live with and sometimes is the cause of non-negligible psychological problems.
It is a real international plague, since it involves about 2 European women out of 5 and almost 50% of Asian and South American women. Oily skin can take on forms from a simple shiny skin all the way to oily skin with a tendency to acne.
Oily skin is above all weak and imbalanced, characterized by an unsightly hormone- dependent hyperseborrhoea. It results in an abnormal and unnatural shininess and in many cases is associated with irritations: the face is shiny and the hair is oily, without freshness and is flattened!
So what is the solution to struggle against this phenomenon that attenuates day after day the basic values of beauty?
Zn PCA is a physiological seboregulator active ingredient specially designed to answer to the problems of oily skin with a tendency to acne. Its effectiveness will be increased when it is combined with a « pilot molecule » naturally present in the skin, pyrrolidone carboxylic acid (L-PCA) that guides it to the target cells.
Zinc is an universal and oligo-essential anti-seborrheic agent with antiseptic activity which limits bacterial proliferation. It uses L-PCA as a physiological vector optimizing zinc bioavailability and as a signal molecule to stimulate epidermal differentiation and reinforcing skin barrier function.
Zinc is the trace element present in the largest quantity in humans after iron. Because of its role in the constitution of more than 90 metallo-enzymes and its activity in almost 200 biochemical reactions of metabolism, zinc is an essential and major element for nutrition, detoxification and for fighting against cell aging. Zinc is involved in the synthesis of nucleic acids, including DNA, but also in protein synthesis, cell division and in the structure and co-enzymatic activation of many key molecules in the organism and in the skin. It plays a role that is just as important in cell differentiation and thus has considerable healing activity. It also prevents the development of microbial infections as a result of its remarkable antiseptic properties.
Considerable scientific research has shown that zinc reduces sebum secretion by inhibiting 5 α-reductase. It has also been shown that the cutaneous application of preparations containing zinc increases zinc levels in the epidermis.
