The invention relates to a cosmetic process for wrinkled skin, comprising either the topical application to the skin of an extemporaneous mixture of a cosmetic composition comprising a polysaccharide polymer grafted with (meth)acrylate groups and of a crosslinking thiol compound having one or more thiol groups; or the sequential application to the skin of a cosmetic composition comprising a polysaccharide polymer grafted with (meth)acrylate groups, followed by the application of a crosslinking thiol compound having one or more thiol groups, or of a cosmetic composition containing same. The invention also relates to the use of the mixture of said grafted polysaccharide polymer and of said crosslinking thiol as a skin tensioning agent. The invention also relates to a cosmetic composition obtained by mixing a cosmetic composition comprising said grafted polysaccharide polymer and said crosslinking thiol. The invention relates to a kit comprising a first cosmetic composition comprising said grafted polysaccharide polymer and a second composition comprising said crosslinking thiol, the first and second compositions each been packaged in a distinct packaging assembly.

is a lower alkyl group having 1 to 6 carbon atoms; and R
5
and R
6
are independently a hydrogen atom or a lower alkyl group having 1 to 6 carbon atoms. A method for manufacturing stereoselective polyolefin, includes polymerizing an olefin in the presence of the catalyst. The present invention provides a catalyst which enables highly isoselective polymerization generating a polymer having significantly high molecular weight and also can prepare stereoselective polyolefin with a narrow dispersity (Mw/Mn) or with a sharp molecular weight distribution, and provides a method for manufacturing stereoselective polyolefin with the catalyst.
