A fun, DIY rubber modeling mask that infuses skin with potent actives for a healthy, dewy-looking complexion. This Rubber Brightening Mask brightens dull skin with vitamin C (ascorbic acid) and sea buckthorn fruit extract, which is rich in vitamins. The result is a more even out skin tone, diminished darkness and a revitalized appearance. The fun application process lets you shake it up and give skin a brightening boost.Dr.Jart uses the same “rubber mask” technique found in high-end Korean spas to achieve equivalent high-performance results—without the fuss of mixing a traditional modeling pack. The innovative cream-to-sheet formula penetrates skin more deeply than a sheet mask to deliver high-potency active ingredients. Each freshly-made mask penetrates skin surface to deliver the benefits your skin needs most quickly and effectively.
