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-induced 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.
Claims8
A monomodal method for treating acne, acne scars, or both, the method consisting essentially of the step of:
- applying to an area of human skin presenting with acne, acne scars, or both 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.
A monomodal method of reducing one or more acne conditions, the acne conditions being selected from the group of inflammation, excessive skin oiliness, large pores on the nose and/or cheeks, and blotchiness, the method consisting essentially of the step of:
- applying to an area of human skin presenting with one or more of the acne conditions 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.
