Hyaluronic acid (HA) is a natural substance found in the skin that helps retain moisture, keeping it plump and hydrated. Over time, the production of hyaluronic acid (along with collagen and elastin) decreases. Consequently, our skin loses volume and moisture.
When used in skincare products, HA acts as a powerful humectant, attracting and holding water in the skin. Its ability to maintain skin hydration is especially beneficial for individuals with dry or aging skin, as it replenishes moisture and revitalizes the skin’s texture.
Allergic reactions or irritation of sensitive skin isn’t common with HA. It’s safe to use on the skin during pregnancy and while breastfeeding, making it a versatile ingredient in skincare formulations.
It’s important to understand that topical HA contains molecules that are large and provide hydration on a surface level, not deep within the skin. In order to add volume and diminish wrinkles, dermal fillers that contain HA are available for injection into the skin. These products work by lifting and filling areas such as the cheeks, the folds around the mouth and chin, and the lips as well as other areas.
