Thiamidol is a Eucerin-patented ingredient. Ten years in development, this highly-effective active is clinically and dermatologically proven to reduce dark spots and prevent their re-appearance.

Panthenol and Dexpanthenol are two names commonly used for the same ingredient.  Panthenol participates in numerous metabolic processes (e.g. energy production, synthesis of fatty acids) and helps to improve hydration in the outermost layers of the skin. Panthenol converts into Panthotenic Acid (a B-Complex Vitamin) in the skin and enhances skin regeneration and repair. When applied regularly, it has been proven to considerably improve symptoms of skin irritation such as dryness, roughness, scaling and redness. It is also an effective moisturizer. Very well absorbed by the skin, it regenerates, stimulates epithelialisation and wound healing. It alleviates irritation and inflammation. 

Lactic Acid is a skin’s own substance, being an essential component of the NMF (= natural moisturizing factor) as well as a AHA (=Alpha-hydroxy acid). 

Lactic Acid  acts in the stratum corneum with a two-fold effect: 

• moisturizing: it reduces skin scaling and balances the skin’s pH value to fight dry skin symptoms
• comedolytic: it inhibits the formation of comedones by helping the skin to shed and exfoliate and thus the pores from becoming clogged.

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.
