Embodiment 1

[0093] (test excipients and compositions)

[0094] Tables 1 and 2 describe general skin test formulations in which skin active ingredients may be added to determine the type of skin benefit attributable to the skin active ingredient. These formulations were prepared in such a way that any skin benefit resulting from topical application of the formulation to the skin was directly attributable to the skin active ingredient tested.

Abstract

Disclosed is a topical skin formulation and method of using the same to increase the integrity of the dermal-epidermal junction in a person's skin by stimulating the production of proteins and enzymes in dermal and epidermal cells that aid in connecting the dermal layer to the epidermal layer. The composition includes an effective amount of a combination of plant extracts comprising argania spinosa kernel extract and cucurbita pepo seed extract; and an effective amount of a combination of amino acids comprising serine and proline.
