Hyaluronic acid is a molecule naturally present in our bodies. In this serum, low molecular weight hyaluronic acid is obtained from bacterial fermentation with wheat. This active ingredient helps retain water and can hold up to 1000 times its weight in water, providing intense hydration to the skin. It is known for its plumping and smoothing properties, ideal for combating wrinkles and revitalizing the skin.

No, it's not an acid that will burn your skin! Hyaluronic Acid is a molecule naturally present in our bodies! It has the ability to retain up to 1000 times its weight in water, providing intense hydration. It is known for its plumping and smoothing properties, ideal for combating wrinkles. There are several "grades" (sizes) of Hyaluronic Acid, from the smallest molecules (low molecular weight) to the largest molecules (high molecular weight).

How Does it Work?

Depending on the size of the Hyaluronic Acid used, the benefits are different:

◉High Molecular Weight:

Hyaluronic Acid composed of large molecules remains on the surface of the skin to form a hydrating, protective, and smoothing film. Perfect for dehydrated skin and small wrinkles caused by superficial dehydration. At 66°30, our two day moisturizers (6-in-1 and Ultra-fresh) as well as the Extreme Balm contain high molecular weight Hyaluronic Acid.

◉Low Molecular Weight:

Hyaluronic Acid composed of small molecules (low molecular weight) penetrates more deeply into the layers of the skin to promote collagen production and treat wrinkles in depth. At 66°30, the Night Cycle, the Extreme Balm, and especially the Extreme Hyper-hyaluronic Serum contain low molecular weight Hyaluronic Acid.

Our Extreme Hyper-hyaluronic Serum contains 5% low molecular weight Hyaluronic Acid, the highest concentration we know of on the market. It revitalizes your skin deeply to effectively prevent the appearance of signs of aging.
