The NIB Sunday Riley Good Genes All-in-One Lactic Acid Treatment is a powerful skincare product designed to target wrinkles and improve skin texture. With a lactic acid formulation, this treatment is suitable for all skin types and contains natural ingredients like hyaluronic acid for added moisture. Perfect for both men and women, this product is free from parabens, sulfates, and perfume, making it ideal for those with sensitive skin. Made in the United States, this 1 fl. oz. serum is part of the Sunday Riley Good Genes product line, known for its high-quality and effective skincare solutions. Note: it appears the product may have leaked a little in the box as there is an oily spot about the size of a quarter. Please see the picture. I have adjusted the price accordingly.
