Compositions comprising specific tetrapeptides, for use in treating, preventing, minimizing, diminishing or reversing various signs of aging of the skin are provided. The compositions are useful in improving the firmness or elasticity of skin, smoothing of fine-lines or wrinkles, reducing skin pores and hyperpigmentation, and increasing skin thickness, radiance and/or softness.

Various salts of tranexamic acid esters compounds are described, along with compositions including such compounds. Methods of use for treatment of external surfaces (e.g. skin) and processes of producing the compounds and compositions are also described.

Selected peptides have been found to repair, by means of nucleotide excision repair (NER), cellular DNA damaged by the exposure to external agents, in particular UV rays and are useful for cosmetic or pharmaceutical use thereof in skin treatment. Compositions for topical application that contain such peptides, preferably carried in liposomes, prevent and treat skin damage caused by the exposure to UV rays, including in subjects affected by xeroderma pigmentosum.

The invention relates to a composition for the making of an emulsifiable triphasic formulation, which consists of a liquid biphasic composition and a powder solid phase, wherein said liquid biphasic composition consists of a hydrophilic phase and a lipophilic phase. The triphasic emulsifiable composition obtained from the combination of the biphasic liquid composition and the solid powder phase by a kit of the invention is particularly suitable for the use in the clinical-dermatological and/or cosmetological fields.

Compositions comprising extracts from marine organisms show beneficial effects on skin ailments. Fine lines, wrinkles, and sagging in skin are improved with the application of compositions with marine extracts. Production of collagen, elastin and hyaluronic acid are increased after application of the compositions.
