Hyaluronic Acid is formed by skin cells and is part of the connective tissue of the skin. One of its key functions is to retain moisture, and it has the ability to bind in between 1,000 and 10,000 times its own weight in water (i.e. one gram binds between one and ten liters). As we age, the skin's natural ability to produce Hyaluronic Acid decreases and wrinkles start to form and deepen.
High and low molecular Hyaluronic Acid
Eucerin uses two different types of Hyaluronic Acid in the Hyaluron-Filler
¹, Hyaluron-Filler + Elasticity
, Anti-Pigment Dual Serum
and Sun Photoaging Control
formulas to effectively target and plump wrinkles from the inside out:
- High molecular Hyaluronic Acid (also known as long-chained Hyaluronic Acid). This remains on skin’s surface and works to improve hydration in the outermost layer of the epidermis – where fine lines and winkles originate.
- Low molecular Hyaluronic Acid(also known as short-chained Hyaluronic Acid). With molecules that are 40 times smaller² than those of high molecular Hyaluronic Acid, low molecular Hyaluronic Acid penetrates further into the epidermal layers where it stimulates skin’s own production of Hyaluronic Acid, replenishing moisture where deeper wrinkles originate.
The Eucerin DermatoCLEAN range of cleansers includes low molecular Hyaluronic Acid.
1 The standard unit for measuring the mass of an atom is a kilo Dalton (kDa). High molecular Hyaluronic Acid has a kDa of 2000 and low molecular Hyaluronic Acid has a kDa of 52. Both are contained in the Hyaluron-Filler, Hyaluron-Filler + Elasticity and Sun Photoaging Control formulas.
2 Excluding Eucerin Hyaluron-Filler Vitamin C Booster which contains low molecular Hyaluronic Acid.
