Skin thickness is decreasing with age. This loss concerns both dermis and epidermis, cells and extracellular matrix. We could show here that percutaneous application of an L-fucose-containing preparation produced an increase of skin thickness and a densification of collagen bundles. We also could show that 3H-L-fucose penetrates in the dermis, a prerequisite for the above mentioned favorable pharmacological activities. These results, together with the previous favorable activities on the downregulation of matrix-degrading enzymes, free radical scavenging and increased cell proliferation confirm the favorable action of fucose and fucose-rich polysaccharides (FROP-s) on the skin by slowing down its aging.
