Abstract: A method of inhibiting PAR2 activation of keratinocytes by boosting the PAR2 inhibition ability of a vitamin B3 compound and an N-acyl amino acid compound with a Laminaria Saccharina extract. The method may be used to improve the appearance of hyperpigmented spots on skin. By determining the amount of Laminaria Saccharina extract needed to boost PAR2 inhibition ability of a vitamin B3 compound and an N-acyl amino acid compound, improved skin care composition can be formulated for the treatment of hyperpigmented skin.

Abstract: A method of improving the appearance of a hyperpigmented spot may comprise the step of applying a composition comprising an effective amount of banyan tree serum fraction, lotus serum fraction, and clover serum fraction to a hyperpigmented spot on a skin surface, wherein the composition is applied for a period of time sufficient to improve the appearance of the hyperpigmented spot. The method may include the step of identifying a hyperpigmented spot on a facial skin surface. Other methods as disclosed include a method for improving the appearance of post-inflammatory hyperpigmentation.

Abstract: A method of improving the appearance of aging skin may comprise the step of applying a composition comprising an effective amount of banyan tree serum fraction, lotus serum fraction, and clover serum fraction to a sign of aging on a skin surface, wherein the composition is applied for a period of time sufficient to improve the appearance of the aging skin. The method may include the step of identifying a sign of aging on a facial skin surface.

Abstract: A method of improving the appearance of a hyperpigmented spot may comprise the step of applying a composition comprising a safe and effective amount of an Laminaria Saccharina extract to a hyperpigmented spot on a skin surface, wherein the composition is applied for a period of time sufficient for the Laminaria Saccharina extract to improve the appearance of the hyperpigmented spot. The method may include the step of identifying a hyperpigmented spot on a facial skin surface. Other methods as disclosed include a method for improving the appearance of post-inflammatory hyperpigmentation.

Abstract: A method of inhibiting tyrosinase activity may involve the step of applying a composition comprising a Laminaria Saccharina extract to a substrate in need of tyrosinase inhibition. The method may further comprise a step of identifying a substrate in need of tyrosinase inhibition. The composition may be left on the substrate and/or repeatedly applied to the substrate to achieve the desired inhibition of tyrosinase activity.

Abstract: A method of improving the appearance of a hyperpigmented spot and improving skin tone may comprise the steps of applying a safe and effective amount of a Laminaria Saccharina extract to a hyperpigmented spot on a skin surface, wherein the Laminaria Saccharina extract is applied for a period of time sufficient to improve the appearance of the hyperpigmented spot; and of applying a skin tone agent to the skin surface, wherein said tone agent is a vitamin B3 compound and wherein the tone agent is applied for a period of time sufficient to improve skin tone.
