Abstract
Cosmetic preparations comprising water soluble fatty acid amide derivatives of hydrolyzed collagen are found to have a substantial degree of permeability to the stratum corneum of human skin and to be effective in improving skin texture, moisture retention and minimizing wrinkles.
Claims5
A cosmetic method for the treatment of skin by the deep absorption of a collagen derivative into the stratum corneum thereof which comprises applying to the skin an effective amount of a water soluble fatty acid amide of a water soluble hydrolysed collagen having a molecular weight in the range of about 1,000-10,000, and allowing said material to remain in contact with the skin for a sufficient period of time to effect substantial penetration thereof.
A cosmetically acceptable composition for application to the skin which comprises a water soluble fatty acid amide of water soluble hydrolysed collagen having a molecular weight ranging between about 1000 and 10,000 capable of deep penetration of multiple layers of the stratum corneum of the skin.
