Sterile and liquid topical composition comprises at least a hyaluronic acid derivative with an activated photodimerizable group that has at least a double bond and includes photodimerizable groups having stylbazolium function of formula (I) or (II) and photodimerizable groups having styrylazolium function of formula (III). R, R1a : H, 1-4C alkyl or 1-4C hydroxyalkyl; R1 : H or 1-4C alkyl; X ->chlorine ion, bromine ion, iodine ion, perchlorate ion, tetrafluoroborate ion, methyl sulfate ion, phosphate ion, sulfate ion, methanesulfonate ion or p-toluenesulfonate ion; R2 : 2-8C divalent alkylene; and A : S, O, NR1 or C(R1) 2. Independent claims are included for: (1) cosmetic treatment of skin and/or the lips comprising topical administration of composition into or through the skin and/or lips, simultaneously illuminating the skin and/or lips to crosslink the composition; (2) a system for treatment of skin and/or the lips comprising a package containing at least a dose of the composition and a composition injection device; and (3) an assembly for treating cosmetic imperfections of skin and/or lips comprising a treatment system and an illumination system for photocrosslinking to the compound.
