- 2. An apparatus as in claim 1 wherein the first composition comprises an active ingredient selected from the group consisting of antibiotics, ascorbic acid, ascorbic acid derivatives, retinoids, hydroquinone, dihydroxyacetone, licorice extract and green tea extract.
- 3. An apparatus as in claim 1 wherein the first active ingredient is an antibiotic.
- 4. An apparatus as in claim 1 wherein the first active ingredient is selected from the group consisting of ascorbic acid and ascorbic acid derivatives.
- 5. An apparatus as in claim 3 wherein the antibiotic is selected from the group consisting of erythromycin, clindamycin, tetracycline, derivatives of erythromycin, clindamycin or tetracycline and pharmaceutically acceptable salts of erythromycin, clindamycin or tetracycline.
- 6. An apparatus as in claim 1 wherein the second composition contains an active ingredient.
- 7. An apparatus as in claim 6 wherein the second composition contains benzoyl peroxide.
- 8. An apparatus as in claim 7 wherein benzoyl peroxide comprises from about 0.1 to about 25 weight percent of the second composition.
- 9. An apparatus as in claim 1 wherein the first composition comprises a retinoid.
- 10. An apparatus as in claim 9 wherein the retinoid is selected from the group consisting of retinol, retinoic acid, retinyl palmitate, retinyl propionate, retinyl acetate and synthetic retinoid mimetics.
- 11. An apparatus as in claim 1 wherein the first composition comprises
i) a polar solvent; ii) said first active ingredient; and iii) a thickening agent in an amount sufficient to impart to the first composition a viscosity of at least 1000 cenetipoise measured at room temperature.
- 12. An apparatus as in claim 10 wherein the first composition contains a polar solvent selected from the group consisting of polyols and polyhydric alcohols.
- 13. An apparatus as in claim 1 further comprising pump means for moving the first and second compositions out of the first and second chambers.
- 14. A method of providing a beneficial effect to the skin of a user comprising
simultaneously dispensing a first composition and a second composition from first and second chambers, respectively, the first being substantially anhydrous and comprising a first active ingredient that is unstable in the presence of water and provides a benefit to the skin of a user, the second composition comprising water and optionally a second active ingredient; and
contacting the first composition and second composition with the skin of a user.
- 15. An method as in claim 14 wherein the first composition comprises an active ingredient selected from the group consisting of antibiotics, ascorbic acid, ascorbic acid derivatives, retinoids, hydroquinone, dihydroxyacetone, licorice extract and green tea extract.
- 16. A method as in claim 14 wherein the first active ingredient is an antibiotic.
- 17. A method as in claim 14 wherein the first active ingredient is selected from the group consisting of ascorbic acid and ascorbic acid derivatives.
- 18. A method as in claim 17 wherein the antibiotic is selected from the group consisting of erythromycin, clindamycin, tetracycline, derivatives of erythromycin, clindamycin or tetracycline and pharmaceutically acceptable salts of erythromycin, clindamycin or tetracycline.
- 19. A method as in claim 14 wherein the second composition contains an active ingredient.
- 20. A method as in claim 19 wherein the second composition contains benzoyl peroxide.
- 21. A method as in claim 20 wherein benzoyl peroxide comprises from about 0.1 to about 25 weight percent of the second composition.
- 22. A method as in claim 14 wherein the first composition comprises a retinoid.
- 23. A method as in claim 22 wherein the retinoid is selected from the group consisting of retinol, retinoic acid, retinyl palmitate, retinyl propionate, retinyl acetate and synthetic retinoid mimetics.
