What I claim is:

1. A cosmetic or dermatological composition for stimulating healing and/or regenerative properties in the skin, hair and/or scalp comprising a NIR light-emitting material, in a cosmetically or dermatologically acceptable vehicle.

2. The cosmetic or dermatological composition of claim 1, wherein the NIR light-emitting material is selected from ceramic composites ceramic-metallo composites, NIRF probes bound to organic luminescent materials, and porphyrin-containing molecules.

3. The cosmetic or dermatological composition of claim 2, wherein the NIR light-emitting material is selected from phosphors of MgSiO3:Eu2+' Dy3+, Mn2+; Ca0.2Zn0.9Mg0.9Si2O6, doped with Eu+2, Dy+3, Mn2+; SrAl2O4: Eu2+' Dy3+ Er3+; La3Ga5Ge3O14:Cr , with or without co-dopants such as Li+, Zn2+ ' Ca2+ ' Mg and Dy3+ ; Ln3Ga2Ge4O14:Cr3+ (Ln = Y, Gd, La or Lu); LiGa5O8:Cr3+; M3Ga2Ge4Oi4:Cr3+ (M= Sr or Ca); La3Ga5SiO14:Cr3+; La3Ga5 5Nb0 5014:Cr3+; La3Ga5GeO14:Cr3+; Gd3Ga5O12:Cr3+; Zn3Ga2Ge2O10:0.5%Cr3+; and combinations thereof.

4. The cosmetic or dermatological composition of claim 2, wherein the NIR light-emitting material comprises a NIRF probe bound to a natural or synthetic polymer, a peptide, a glucose analog or combinations thereof.

5. The cosmetic or dermatological composition of claim 1, wherein the NIR light-emitting material has the general formula ZnxGayGezO(x+(3y/2)+2z):tCr3+, mR where R is a co-dopant selected from a group consisting of alkaline earth ions, lanthanide ions and Li+ ions; x, y and z are integers from 1 to 5; t is 0.01 to 5mol%; and m is 0 to 5mol%.

6. The cosmetic or dermatological composition of claim 1, which persistently emits NIR light for at least about 1 hour to about 6 weeks after exposure to UV or fluorescent light.

7. The cosmetic or dermatological composition of claim 6, which persistently emits NIR light for at least about 8 hours to about 2 weeks.

8. The cosmetic or dermato logical composition of claim 7, wherein the NIR light-emitting material activated by exposure to UV or fluorescent light for about 1 minute to about 10 minutes.

9. The cosmetic or dermatological composition of claim 1, which is anhydrous, aqueous-based or solid.

10. The cosmetic or dermatological composition of claim 1, which is in the form of a solution, a serum, a gel, a cream, a lotion, a toner, a mousse, a spray, an ointment, an essence, a paste or a solid.

11. The cosmetic or dermatological composition of claim 1, wherein the NIR light-emitting material has a particle size in the range of from about 100 nanometers to about 100 micrometers.

12. The cosmetic or dermatological composition of claim 11, wherein the NIR light-emitting material has a particle size in the range of from about 500 nanometers to about 20 micrometers.

13. The cosmetic or dermatological composition of claim 1, wherein the NIR light-emitting material is present in the composition in an amount in the range of from about 0.001 wt. % to about 75 wt. %.

14. The cosmetic or dermatological composition of claim 1, wherein the healing and/or regenerative property is one or more of stimulating the production of collagen, stimulating the production of elastin, reducing the size of pores in the skin, reducing the size and/or depth of wrinkles in the skin, reducing the appearance of cellulite, reducing inflammation in the skin, enhancing DNA synthesis and repair, evening the skin tone, treating acne, reducing the appearance of acne scarring, stimulating the growth cycle of hair follicles, reducing dandruff-causing seborrhoeic inflammation, and stimulating fatty tissue reduction.

15. The cosmetic or dermatological composition of claim 1, comprising a cosmetic ingredient selected from oils, surfactants, film formers, pigments, powders and thickeners.

16. The cosmetic or dermatological composition of claim 1, comprising a cosmetic ingredient selected from the group consisting of moisturizers, humectants, botanical extracts, sunscreen agents, and DNA repair enzymes.

17. The cosmetic or dermatological composition of claim 1, in the form of a foundation, a blush, an eyeshadow a concealer, a lipgloss, a lip balm, a lipstick, a mascara, a shampoo, a hair conditioner, a facial or hair mask, a facial or hair serum, a hair styling lotion or balm, a sun care product, a depilatory, an exfoliant, or a facial or body moisturizer or treatment product.
