1. A method of inhibiting melanogenesis in skin of a person in need thereof, the method comprising topically applying to skin of the person a composition comprising 0.1 to 3% by weight of niacinamide, 0.1 to 3% by weight of navy bean extract, and 0.01 to 1% by weight of ferulic acid, and the composition does not include a pyridoxine compound, and wherein topical application of the composition inhibits melanogenesis and does not provide protection from infrared radiation and/or visible light.
2. The method of claim 1 , wherein a second skin care composition is applied to the skin before application of the composition to the skin or the composition is combined with a second skin care composition prior to application to the skin.
3. The method of claim 1 , wherein the composition comprises the said amount of ferulic acid to inhibit tyrosinase and/or the melanosome transfer pathway to reduce free radical formation and/or reduce synthesis of discoloration factors.
4. The method of claim 1 , wherein the composition comprises the said amount of niacinamide to inhibit the melanosome transfer pathway to reduce production of discoloration factors and/or reduce integration of discoloration factors into skin cells.
5. The method of claim 2 , wherein the second skin care composition affects a brightening effect on skin.
6. The method of claim 2 , wherein the second skin care composition does not affect a brightening effect on skin.
7. The method of claim 1 , wherein the composition further comprises one or more of: a humectant, a skin conditioning agent, a viscosity controlling agent, a preservative, and/or a pH adjuster.
8. The method of claim 1 , wherein the composition further comprises an effective amount of one or more of: water, PEG-8, glycerin, ethoxydiglycol, and/or xanthan gum to moisturize, condition, and/or enhance a skin product's brightening effect.
9. The method of claim 8 , wherein the composition comprises:
1 to 95% by weight water;
1 to 25% by weight PEG-8;
0.1 to 15% by weight glycerin;
0.1 to 15% by weight ethoxydiglycol; and/or
0.01 to 5% by weight xanthan gum.
10. The method of claim 1 , wherein the composition further comprises one or more of: propanediol, phenoxyethanol, and/or sodium citrate.
11. The method of claim 10 , wherein the composition comprises:
0.1 to 15% by weight propanediol;
0.01 to 5% by weight phenoxyethanol; and/or
0.01 to 5% by weight sodium citrate.
12. The method of claim 1 , wherein the composition further comprises 35 to 85% by weight of water.
13. The method of claim 1 , wherein the composition further comprises 1 to 10% by weight of glycerin.
14. The method of claim 1 , wherein the composition does not provide protection from visible light.
15. The method of claim 1 , wherein the composition further comprises Opuntia tuna extract.
16. A method of enhancing the activity of a skin care composition, the method comprising combining an enhancing composition and the skin care composition,
wherein the enhancing composition comprises 0.1 to 3% by weight of niacinamide, 0.1 to 3% by weight of navy bean extract, and 0.01 to 1% by weight of ferulic acid,
wherein the enhancing composition and the skin care composition do not include a pyridoxine compound, and the enhancing composition does not provide protection from infrared radiation and/or visible light, and
wherein combining the enhancing composition and the skin composition increases or promotes an ability of the skin care composition to inhibit melanogenesis.
17. The method of claim 1 , wherein the composition comprises 2 to 3% by weight of niacinamide, 0.3 to 2% by weight of navy bean extract, and 0.1 to 0.4% by weight of ferulic acid.
18. The method of claim 1 , wherein inhibiting melanogenesis comprises reducing skin discoloration, reducing or improving uneven skin tone, improving skin brightness, or a combination thereof.
