Claims21
A method for modifying skin appearance of a person and/or in modifying the skin feel as perceived by the person comprising applying to the skin of the person a cosmetic and/or skin care composition comprising a surface-reacted calcium carbonate having a volume median particle size d50 from 0.1 to 90 μm,
- wherein the surface-reacted calcium carbonate is a reaction product of natural ground calcium carbonate or precipitated calcium carbonate with carbon dioxide and one or more H3O+ ion donors, wherein the carbon dioxide is formed in situ by the H3O+ ion donors treatment and/or is supplied from an external source,
- the amount of the surface-reacted calcium carbonate in the cosmetic and/or skin care composition is from 0.1 to 5 wt-% based on the total weight of the cosmetic and/or skin care composition, and
