Abstract
Skin care compositions and methods are provided for improving the appearance of skin affected by aging, photodamage and/or oxidative stress. Specifically, adhesive materials containing cosmetically active ingredients, e.g., one or more antioxidants such as Vitamins A, C and/or E, or moisturizers are applied in concentrated dry powdered form to target areas including the frownline area of the forehead, the front of the neck, the crows-feet area near the eyes, the upper lip and the nasolabial area using a transdermal patch having an acidity approximating human skin acidity of 5.5, preferably by an appropriate ratio of ascorbic acid and ascorbate salts.
