The present invention relates to a cosmetic or dermatological composition of sol/gel type for making up and/or caring for keratin materials characterized in that it comprises the product resulting from the reaction: (a) of at least one alkoxysilane monomer or oligomer of formula (I) R1xSi(OR2)(4-x) or of formula (II) [R1y (OR2)z SiO ((4-&#x3b3;-&#x3b6;)/2)]&#x3b7; in which R1 represents, independently, a nucleophilic group other than a hydroxyl, or a (Ci-C2o)alkyl group, R2 represents, independently, a (Ci-Cio)alkyl group, and (b) of an amount of water corresponding to a number of moles of water, determined according to the following equation: X&#x2212;(llAlkoxysilanes&#xd7;llbAlkoxy groups)/nH2o with nH2o=Number of moles of water, nAikoxysiianes=Number of moles of alkoxysilane compounds, nbAikoxy groups=Weighted mean of the number of alkoxysilane groups per alkoxysilane compound, and X is a number greater than 2. It also relates to an associated cosmetic process and an associated kit for coating keratin materials.

Cosmetic composition comprising at least one alkoxysilane

The present invention relates to a process for making up the lips, comprising at least one step of placing in contact on the surface of said lips: &#x2014;at least one water-soluble organic acid, &#x2014;at least one alkali metal or alkaline-earth metal carbonate or bicarbonate, and &#x2014;an aqueous medium, said organic acid and said carbonate or bicarbonate being present in different compositions.
