A winner of the GH Beauty Lab’s face serum test, SkinCeuticals’ formula has high levels of vitamin B3 to stimulate cell turnover. The light liquid was the best of the serums tested by the GH Beauty Lab at reducing wrinkles, by 5% after four weeks of use. It earned raves from testers for visible wrinkle softening, brightening and firming. “I could see plumpness in my skin the next day — I was shocked,” a tester said. “Almost immediate results on my fine lines,” another remarked.
Like a refreshing drink for oily, combination or acne-prone skin, No7’s moisturizer hydrates with lipids, glycerin and plant-derived sugars without heaviness or greasiness, thanks to a featherlight gel texture. This GH Seal star formula increased skin’s moisturization for three days post-application and 84% of testers said their skin was glowing after one week of use, according to Lab data.
