30 ML / 1 FL OZ KERACELL® Facial Hair Inhibiting Serum with MHCsc™ Technology contains Pilisoft™ which is an extract derived from the leaves of Gymnema Sylvestre and rich in gymnenic acids, successfully prolonging and enhancing the effects of hair removal treatments. Its innovative mechanism of action is based on the important role gymnenic acids play in the inhibition process of hair follicle activity. Tests have demonstrated its ability to reduce keratinocyte proliferation and impair the mitotic activity of hair follicles. Its efficacy on both slowing hair growth and reducing hair density has been confirmed by a clinical study with significant results obtained over a one-month period.
