This invention is based upon the discovery that a mixture of ethyl lactate and isoamyl lactate can be used to improve the penetration of active ingredients in skin care formulations through the outer layers of the stratum corneum and viable epidermis and into the dermis layer of the skin structure. The present invention more specifically discloses a method of rejuvenating skin comprising topically applying a topical formulation to the skin, wherein the topical formulation is comprised of ascorbic acid, an amino acid selected from the group consisting of phenylalanine and tyrosine, a non-toxic zinc salt, carnosic acid, α-tocopherol, 0.01 weight percent to 20 weight percent of a mixture of ethyl lactate and isoamyl lactate, wherein the weight ratio of the ethyl lactate to the isoamyl lactate is within the range of 1:10 to 20:1, and a pharmaceutically acceptable carrier.
A method of rejuvenating skin affected by intrinsic aging and/or photo-induced aging, said method comprising topically applying a topical formulation to the skin, wherein said topical formulation is comprised of about 1 weight percent to about 20 weight percent ascorbic acid, about 1 weight percent to about 10 weight percent of phenylalanine, about 0.5 weight percent to about 5 weight percent of a non-toxic zinc salt, a marjoram extract containing carnosic acid, about 1 weight percent to about 30 weight percent α-tocopherol, and about 0.01 weight percent to about 20 weight percent of a mixture of ethyl lactate and isoamyl lactate, wherein the weight ratio of ethyl lactate to isoamyl lactate is within the range of about 1:10 to about 20:1, and a pharmaceutically acceptable carrier.
