Let’s talk hyaluronic acid, known for its incredible ability to hydrate, plump, and rejuvenate the skin, this naturally occurring molecule has become a staple in the routines of skincare enthusiasts. Now there is science behind the magic of hyaluronic acid and we at Saint Louve are here to explain how it works to give you that coveted youthful glow.

Hyaluronic acid (HA) is a carbohydrate molecule that naturally occurs in our bodies, particularly in our skin, connective tissues, and eyes. It is what we call a humectant which means has the ability attract and retain water like a sponge. It's a key player in maintaining the skin's moisture and overall health. HA is renowned for its exceptional water retention properties, as it can hold up to 1000 times its weight in water, making it a hydration powerhouse.

The Science Behind HA's Hydration:

Water Attraction: HA's structure enables it to attract and bind water molecules, creating a reservoir of hydration within the skin. This plumps up the skin, reduces the appearance of fine lines and wrinkles, and gives you that dewy, youthful complexion.

Epidermal Barrier: HA also plays a crucial role in maintaining the skin's barrier function. A well-hydrated barrier is essential for keeping out harmful pollutants and irritants, while also locking in essential moisture.

There are different molecular weights of HA which will determine their role in skincare. High Molecular Weight HA is large enough that it sits on the skin’s surface providing immediate hydration and works in attracting and trapping moisture from the environment. Whereas Low Molecular Weight HA penetrates the deeper layers of the skin to offer long lasting hydration and aiding in collagen synthesis. This is particularly beneficial for addressing signs of aging and improving skin elasticity.

As we age our bodies produce less and less hyaluronic acid which can lead to dryness and over time, fine lines and wrinkles. This is why hyaluronic acid is a must have ingredient in everyone’s skincare regime. Saint Louve’s most loved Vitamin B3, B5 & Hyaluronic Acid Hydrating Serum contains three molecular weights of Hyaluronic Acid and Polyglutamic Acid which will visibly plump the skin with both immediate and long-term hydration. Our HA-rich serum delivers concentrated hydration and can be used on its own or layered with our other Saint Louve Serums to create optimal results.
