A method for reducing a presence of sebum on skin, reducing an appearance of shiny skin, or reducing an appearance of the size of skin pores, the method comprising topically applying to skin a composition comprising an extract of Bambusa vulgaris wendl shoots, Lonicera japonica leaf extract, and charcoal, wherein topical application of the composition to the skin reduces the presence of sebum on the skin, reduces the appearance of shiny skin, or reduces the appearance of the size of the skin pores.

The present invention relates to a compound represented by the following formula (I): A[B—(C).sub.v].sub.w, wherein A is a photoprotective moiety, B is a linker, C is a functional group, v is an integer from 1 to 2000, and w is an integer from 1 to 6. It also relates to a composition comprising the same and, more particularly, to a cosmetic or a sunscreen composition. It also relates to the use of such compounds in cosmetic and therapeutic applications. The invention also relates to the use of such compounds for reducing photodegradation and/or photoinstability of pharmaceuticals and cosmetics. The invention further relates to a material comprising a support and such a compound adhered to said support.

The present invention relates to a composition comprising i) at least one 4-(3-ethoxy-4-hydroxyphenyl)butan-2-one compound; ii) at least one preserving agent other than i) and/or antioxidant; iii) at least one surfactant chosen from the surfactants; iv) at least one polymer, notably a thickening polymer, which is preferably organic, and v) optionally a fatty substance. The invention also relates to the use of i) to vi) as antimicrobial agent, to a process for treating keratin materials using the composition comprising i) to vi) and to a kit comprising ingredients i) to vi).

The combination of i) ii), iii), iv) and optionally v) makes it possible to obtain an antimicrobial mixture which has excellent antimicrobial activity, in particular with respect to Aspergillus niger, Escherichia coli, Staphylococcus aureus and Candida albicans. In addition, the formulations remain stable over time while at the same time retaining antimicrobial activity over time even after 7 days, 15 days, 1 month, and at room temperature.

The present invention is related to a skin care composition comprising (1) a physiologically acceptable medium and (2) a synergistic composition consisting of: a blend of a Nelumbo nucifera (Sacred Lotus) serum fraction and a Camellia sinensis (Tea) serum fraction in a respective weight ratio of 75:25; or a blend of a Nelumbo nucifera (Sacred Lotus) serum fraction and a Chamomilla recutita (German chamomile) serum fraction in a respective weight ratio of 75:25. The invention also relates to a method for improving skin appearance associated with skin aging comprising applying compositions thereof.

Provided herein are sunscreen formulations containing a metal oxide sunscreen, squalane, and an antioxidant. The sunscreen formulations provided have increased SPF per unit mass of the metal oxide compared to sunscreen formulations that contain metal oxide without the addition of squalane and antioxidant. Also provided are methods of preventing UV damages to skin involving the application of the sunscreen formulation.
