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.
