Pour Moi’s complex Réponse du Climat utilizes Hyaluronic Acid in varying molecule sizes so this powerful, water-holding ingredient works in your favor ALWAYS and EVERYWHERE.
Cinderella has her fairy godmother—you have Hyaluronic Acid
Hyaluronic Acid is a sugar, famous for its ability to hold up to a thousand times its weight in water. No other hydrating ingredient can claim the same. But it’s not just a water-holding ingredient—it’s also water-grabbing. Hyaluronic Acid latches onto moisture wherever it can find it. It either grabs it externally from the air or internally from deep inside your skin. Cinderella only had until midnight—you have until you're 25. Naturally. Hyaluronic Acid is found naturally within the body, and it does it all when it comes to a healthy and youthful complexion. It's mainly responsible for why skin is plump, soft, and supple when you're a baby. As we get older, starting at the age of 25, the body produces less Hyaluronic Acid. This eventually causes the appearance of dryness, fine lines, sagging, and wrinkles.
Enough with the fairy tale—let’s get chemical
What a lot of people don’t realize about Hyaluronic Acid today is that it shouldn’t count any longer as just one ingredient. Beauty chemistry has expanded the possibilities of how Hyaluronic Acid can penetrate into the skin and target different layers for moisturizing. It not only plumps the skin instantly, but has long-lasting hydration benefits. When Hyaluronic Acid was first introduced as an ingredient, it only came in the form of large molecules, limiting its ability to absorb deeper into the skin. Today, Hyaluronic Acid comes in varying molecule sizes, where each size has a different effect on the skin. Check out this clinical study that shows nearly perfect levels of hydration and anti-aging actions using Hyaluronic Acid. If it's hard to imagine the concept of different forms of Hyaluronic Acid with different molecule sizes, just think about water and its different forms. Ice is water with large molecule size. Mist is water with very small molecule size. [Want to know more about water? Keep reading: We’re Made in France—But Why?]
Hyaluronic Acid is the best example that one size doesn’t fit all
Cosmetic dermatologist Leslie Baumann M.D. was the first to warn that Hyaluronic Acid by itself doesn't work properly in dry climates. Today, most scientists have come to the same conclusion. Here's why: Hyaluronic Acid in the form that has only large molecules stays on the surface of the skin. If humidity is low, it pulls moisture only from inside the skin and not from the atmosphere. This may cause dehydration and TEWL (trans epidermal water loss)—the opposite effect of what a moisturizing ingredient is supposed to do!
Hyaluronic Acid is climatewise in Réponse du Climat
Pour Moi's complex Réponse du Climat utilizes Hyaluronic Acid in varying molecule sizes—butwe take it even further. We formulate it climatewise. Because Hyaluronic Acid is not just water-holding but also water-grabbing, the optimal formulation depends on the humidity in the air. Depending if humidity is low, medium, or high in your climate, Hyaluronic Acid must be formulated according to the climate and paired strategically with other moisturizing agents in order to be effective ALWAYS and EVERYWHERE.
