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 converts into Pantothenic 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.

Panthenol/Dexpanthenol is also an effective moisturizer. It improves hydration in the outermost layers of the skin and helps to reduce transepidermal water loss.

Lactic Acid (also known as Lactate) is part of skin’s Natural Moisturising Factor (NMF) and a key component of skin’s protective acid mantle which regulates the pH value of skin. It absorbs and retains moisture within the outermost layer of the skin and so plays a vital role in skin condition. It is also comedolytic.

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.
