Crescina Transdermic Re-Growth Rapid-Intensive is a topical cosmetic treatment for physiological hair growth with Transdermal Technology, thanks to which the active substances of the Re-Growth complexes, HFSC and Plate-Like Complex can penetrate the hair system. Not only through the transfollicular route (opening of the follicle) but also by transdermal route through the skin layers of the scalp (ex vivo test with Franz Cells) assisted both by their low molecular weight and by the presence of penetration facilitators, or enhancers : the traditional 3 (Pentylene Glycol, Decylene Glycol, Caprylyl Glycol), plus the two new enhancers (Propylene Glycol and Butylene Glycol) that improve the absorption of functional molecules in the scalp (Swiss Patent CH 711 466).
