Abstract
A therapeutic method is described in which copper is delivered into the skin as a complex with sodium chlorophyllin. Sodium copper chlorophyllin is encapsulated in suitable lecithin-type liposomes, containing a high concentration of linoleic acid and having diameters in the range 150-350 nanometers. The method provides therapeutic benefits in the treatment of environmentally-induce premature skin aging, excessively oily skin, acne and acne-related skin disorders, acne-rosacea, and also stimulates the natural tanning response of skin to sunlight and other ultraviolet-containing radiation.
Claims4
A monomodal method for reducing the appearance of one or more clinical signs of premature skin aging, the clinical signs of premature skin aging being one or more of skin wrinkling, sagging, roughness, blotchiness and uneven pigmentation, the method consisting essentially of the step of:
- applying to an area of human skin presenting with one or more clinical signs of premature skin aging a topical composition comprising either or both of copper chlorophyllin and sodium copper chlorophyllin in an aqueous solution,
- the aqueous solution contained within liposomes,
- the liposomes having a lecithin shell having a fatty acid component, more than 50 wt-% of the fatty acid component being linoleic acid,
- the liposomes having an average diameter between 150 to 350 nanometers, and
- wherein the liposomes are dispersed in a dermatologically-acceptable carrier.
