[Set Contents] ・Kiehl's DS Plump Collagen Serum 1.5mL x 32 Collagen decreases by approximately 1% each year after peaking at age 5. It is essential for skin firmness, but due to the size of its molecules, it is difficult for it to penetrate*2 simply by applying it, making it a difficult ingredient to unleash its full potential. Kiehl's tackles this challenge with cutting-edge proprietary technology that thoroughly pursues "speed*4 and precision". The focus is on 15 types of collagen, including baby collagen, which is abundant in young skin. It is formulated with "next-generation collagen peptide*1" developed with advanced biotechnology as a key ingredient. The "double-action liposome," like a two-stage rocket, quickly delivers the ingredients*1 deep into the skin*2. Furthermore, by employing precise analysis technology like GPS, it has succeeded in visualizing the penetration*2 locations. Kiehl's unique design has made it possible to achieve an approach that "delivers ingredients to the targeted location"*2, rather than simply applying ingredients. Each application leaves you with a feeling of euphoria as it leads to plump, radiant skin, and with daily "collagen savings," it aims for firm, dense skin that pushes back from within. *1 Synthetic human recombinant polypeptide-69, synthetic recombinant octa synthetic human recombinant polypeptide-69 (both skin conditioning ingredients) *2 To the stratum corneum *3 Refers to good absorption *4 Refers to penetration and absorption How to use After washing your face in the morning and evening and preparing your skin with lotion, apply an appropriate amount (2 pumps) to your entire face, including the eye area.
