Yves Saint Laurent introduces a new skincare approach with its Signature Layering Routine. Layering skincare products can enhance the potency of each one, increasing the likelihood of seeing noticeable results on the skin. With this knowledge, Yves Saint Laurent combines three iconic serums?each formulated to address different concerns?to help reveal, radiant, more youthful skin. Set includes: - Forever Youth Liberator Serum (0.5 oz.): the first layer of the routine, this award-winning formula activates an anti-wrinkle lift, instant radiance and plumper-looking skin. - Forever Light Creator Serum (0.5 oz.): the second layer of the routine, it illuminates and promotes dark spot correction, skin tone uniformity and refined texture. - Forever Youth Liberator Eye Zone Serum (0.5 oz.): the third layer of the routine, it targets the entire eye zone, lifting, de-puffing and correcting dark circles. How to use: Always go from the lightest texture (serums) to the most rich (moisturizers), as serums are the thinnest products and deliver active ingredients to the skin. Finish by sealing the serums on the skin with a moisturizer. Wait at least one minute between each layer to avoid pilling.
