Claims
- 1. A method of promoting exfoliation of the skin and/or for stimulating renewal of the epidermis comprising applying to skin in need thereof an amount of at least one compound of formula (I):
- 2. The method according to claim 1, wherein the compound of formula (I) is selected from those compounds where R1═R2═R3═H and their salts.
- 3. The method of claim 1, wherein said salts are inorganic salts.
- 4. The method of claim 2, wherein said salts are inorganic salts.
- 5. The method of claim 1, comprising applying trisodium methylglycinediacetate to skin in need thereof in an amount sufficient to exfoliate the skin and/or stimulate renewal of the epidermis.
- 6. The method of claim 1, wherein at least one of R1, R2 and R3 is a sugar residue selected from the group consisting of glucose, galactose, xylose, fucose, mannose and polysaccharides.
- 7. The method of claim 1, wherein said at least one compound of formula (I) is present in a composition comprising said at least one compound and a physiologically acceptable medium.
- 8. The method according to claim 7, wherein said composition contains from 0.1 to 10% by weight of compound of formula (I), based on the total weight of the composition.
- 9. The method of claim 5, wherein said trisodium methylglycine diacetate is present in a composition comprising said trisodium methylglycine diacetate and a physiologically acceptable medium.
- 10. The method according to claim 9, wherein said composition contains from 0.1 to 10% by weight of trisodium methylglycine diacetate, based on the total weight of the composition.
- 11. A method of preventing or treating dry skin and/or signs of skin ageing and/or skin pigmentation comprising applying to skin in need thereof an amount of at least one compound of formula (I):
- 12. The method according to claim 11, wherein the compound of formula (I) is selected from those compounds where R1═R2═R3═H and their salts.
- 13. The method of claim 11, wherein said salts are inorganic salts.
- 14. The method of claim 12, wherein said salts are inorganic salts.
- 15. The method of claim 11, comprising applying trisodium methylglycine diacetate to skin in need thereof in an amount sufficient to prevent or treat dry skin and/or signs of skin ageing and/or skin pigmentation.
- 16. The method of claim 11, wherein at least one of R1, R2 and R3 is a sugar residue selected from the group consisting of glucose, galactose, xylose, fucose, mannose and polysaccharides.
- 17. The method of claim 11, comprising applying trisodium methylglycine diacetate to skin in need thereof in an amount sufficient to prevent or treat dry skin and/or signs of skin ageing.
- 18. The method of claim 11, wherein said at least one compound of formula (I) is present in a composition comprising said at least one compound and a physiologically acceptable medium.
- 19. The method according to claim 18, wherein said composition contains from 0.1 to 10% by weight of compound of formula (I), based on the total weight of the composition.
- 20. The method of claim 15, wherein said trisodium methylglycine diacetate is present in a composition comprising said trisodium methylglycine diacetate and a physiologically acceptable medium.
- 21. The method according to claim 20, wherein said composition contains from 0.1 to 10% by weight of trisodium methylglycine diacetate, based on the total weight of the composition.
