Boots No7 Lift & Luminate Day & Night Serum targets the appearance of 3 key signs of visible aging: wrinkles, lack of firmness, and uneven skin tone. During the day, our skin brightening complex is designed to help diminish the appearance of age spots while our firming complex helps provide smoother and firmer looking skin. At night, a PHA exfoliates the skin’s surface to revitalize and even skin tone. The serum starts working on day one to soften and smooth skin. In trials, most consumers said they saw a significant improvement in the 3 key signs of aging in 4 weeks. Hypo-allergenic. Kind to even the most sensitive skin.
