AN-Acide hyaluronique
Hyaluronic acid
| Type of ingredient | Moisturizer |
| Available forms | Serums, essences, creams … |
| Origin | It is a molecule that occurs naturally in your skin and in the connective tissue of your body. Hyaluronic acid is a polysaccharide naturally present in the human body. It acts as a cushioning and lubricating agent for our joints, nerves, hair, skin and eyes. Hyaluronic acid also has another form: sodium hyaluronate which is its saline form and is more stable and has a smaller molecular size which allows it to penetrate the skin better. Both hyaluronic acid and sodium hyaluronate are used in beauty products, and specialists call them both “hyaluronic acid”. |
| Main benefits | Moisturises the skin, reduces the appearance of wrinkles, replenishes cell moisture, accelerates wound healing. |
| Characteristics | Hyaluronic acid can draw moisture from the air to keep your skin moist, retaining nearly 1000 times its own weight in water. Lack of moisture is one of the main culprits in skin aging, so this ingredient, which draws moisture to your skin, is a must when it comes to repairing your skin’s moisture barrier. Because the composition of hyaluronic acid is so closely related to the substances in our bodies, it works well as a filler that does not cause major irritation. |
| Target group | In general, hyaluronic acid is safe for all skin types, but it is particularly useful for dry skin. However, people with rosacea or eczema may want to test it first to make sure it does not irritate the skin. |
| Frequency | Hyaluronic acid can be applied topically twice a day, in the morning and evening during your skin care routine. |
| Association | It works well with vitamin C, vitamin B5 and glycolic acid. The hyaluronic acid and vitamin C overlap well and do not cancel or neutralise each other. It can also be used with other potentially irritating serums, which will reduce irritation. |
| Dissociation/ Contraindication | There are no known negative reactions with hyaluronic acid. |
| Side effects | In general, there are no known side effects of hyaluronic acid, at least the topical versions. |
| Use | Institute treatments can help hyaluronic acid penetrate deeper into the skin. When combined with a HydraFacial, for example, the serum is infused into the skin for better or more effective penetration of the small molecules than application to the top of the epidermis alone. Then follow with a moisturiser and sunscreen with an SPF of at least 30 in the morning. |
