Five rose stem cells are blended with four rose extracts to create Rose Stem Cell from Peter Thomas Roth, a gel that helps hydrate skin. The gel mask contains ingredients that help dull skin appear more radiant, reduce the appearance of fine lines and wrinkles, brighten the look of the skin, and reduce the look of rough skin. How do I use it: Apply a generous coat onto clean skin. Allow to remain on for 10 minutes. Rinse with cool water. For treatment that feels cool, refrigerate and apply as a mask or apply a thin layer and leave on overnight. Use two to three times a week or daily, depending on your skin needs.
