Pink Quote

A clinical study found that 100 percent of women surveyed felt Sunday Riley Good Genes Lactic Acid Treatment was the most effective skin-plumping product they have ever used and would definitely recommend it to a friend—and I can confirm I am deeply seated in that group of women. When I don’t know what serum to prioritize in my skin care, I call on this one because it does it all. —Allie Hogan, senior beauty editor
