The present invention provides a composition formed by combining retinol, at least one retinol derivative, or a mixture thereof with at least one peptide copper complex. Surprisingly, it has been found that when a peptide copper complex or peptide copper complex derivative is present, the ability of retinol or a retinol derivative to undergo cell growth and differentiation is increased. Even more surprisingly, it has been found that in the presence of retinol or a retinol derivative, the effect of the peptide copper complex to reduce the signs of photodamage or aging in the skin is enhanced. Thus, the present invention is based, at least in part, on a synergistic interaction between retinol or a retinol derivative and a peptide copper complex. |
