Abstract

A kit for skin care intended to soften cutaneous signs of ageing, contains in separate packagings, a microdermabrasion composition, a peeling composition, a soothing composition and an anti-ageing composition.

Claims

1. A kit for skin care intended to soften cutaneous signs of ageing, comprising:

a first packaging comprising a microdermabrasion composition which comprises at least 5% by weight of metal oxide particles,

at least one second packaging comprising a peeling composition which comprises at least 5% by weight of at least one desquamating agent,

a third packaging comprising a soothing composition comprising a thermal or mineral water having a mineral content of at least 300 mg/l,

a fourth packaging comprising a composition which comprises at least one anti-ageing active principle chosen from;

compounds which enhance the synthesis of collagen and/or of elastin and/or of glycosaminoglycans and/or of proteoglycans and/or of fibronectin and/or of laminin, compounds which inhibit the decomposition of collagen and/or of elastin, skin relaxants, agents which inhibit the glycation of proteins, agents which enhance the proliferation of keratinocytes and/or of fibroblasts, agents which enhance the differentiation of keratinocytes, and their mixtures.

2. The kit according to claim 1, wherein the metal oxide particles comprise at least one selected from the group consisting of magnesium oxide particles and aluminium oxide particles.

3. The kit according to claim 1, wherein the metal oxide particles have a mean particle size ranging from 100 to 180 μ

m.

4. The kit according to claim 1, wherein the metal oxide particles represent from 10 to 30% of the total weight of the microdermabrasion composition.

5. The kit according to claim 1, wherein the microdermabrasion composition has a pH of between 5.5 and 7.

6. The kit according to claim 1, wherein the microdermabrasion composition further comprises at least one heterogeneous polysaccharide.

7. The kit according to claim 1, wherein the peeling composition comprises an α

-hydroxy acid as a desquamating agent.

8. The kit according to claim 1, wherein the peeling composition has a pH of between 3.5 and 4.5.

9. The kit according to claim 1, wherein the peeling composition is impregnated on a wipe.

10. The kit according to claim 1, wherein the soothing composition comprises 100% by weight of mineral or thermal water.

11. The kit according to claim 1, wherein the anti-ageing active principle is ascorbic acid.

12. The kit according to claim 1, wherein the anti-ageing composition has a pH of between 5.5 and 6.5.

13. The kit according to claim 1, wherein the microdermabrasion composition and/or the anti-ageing composition are in the form of an oil-in-water emulsion.

14. The kit according to claim 1, wherein the peeling composition is in the form of an aqueous gel.

15. The kit according to claim 1, wherein the anti-ageing composition further comprises at least one chosen from the group consisting of at least one moisturizing agent, at least one antioxidant or agent for combating free radicals, at least one organic or inorganic photoprotective agent which is active in the UV-A and/or UV-B region, and mixtures thereof.

16. The kit according to claim 1, wherein the peeling composition comprises glycolic acid, as a desquamating agent.

17. The kit according to claim 1, wherein the anti-ageing composition comprises glycerol.
