Amphiphilic association structures in a model skin lotion with hydroxy acids.

abstract：:Skin firmness, elasticity and tone are gradually lost with age. These changes originate in the dermis and correspond to a decrease in the ability of cells, particularly the fibroblasts, to regenerate the molecules which make up the extracellular matrix. Skin ageing is also characterized by a reduction of the epidermal...
