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 depletes 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 and 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 smaller 1 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.
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.
Milk Thistle Oil
The oil of the Milk Thistle plant (also known as Lady's Thistle or Silybum Marianium) is a common ingredient in anti-aging skincare. It contains Linoleic acid (an Omega-6 fatty acid) and is known to nourish skin and improve radiance. It is one of the oils in Eucerin Elasticity + Filler Facial Oil.
Silymarin is extracted from the fruits of the Milk Thistle plant (also known as Lady's Thistle). It is a powerful antioxidant, protecting collagen and elastin from oxidative stress, and helps to strengthen skin's microcirculation system at a cellular level.
It is a key active in the Eucerin Hyaluron-Filler + Elasticity formula.
Vitamin E (also known as Tocopherol) is a powerful anti-oxidant that protects skin against the free radicals that cause oxidative stress and helps to support its natural resilience. It is one of the ingredients in Eucerin Elasticity + Filler Facial Oil.
