Eucerin UreaRepair PLUS

Behind the science of Eucerin UreaRepair PLUS

Eucerin is a leader in innovative and effective care for dry, very dry and extremely dry skin with more than 100 years of expertise in developing products that care for dry skin conditions.

In this article Dr Alexander Filbry, Head of Product Development for Body Care at Eucerin, looks at the causes of dry skin and the science behind Eucerin’s UreaRepair PLUS range. He explains how the unique ingredient combinations in the range work to deliver immediate + 48h dry skin relief.

What causes dry skin?

Dry skin is a very common condition and often results in visits to dermatologists,” explains Dr Filbry. “Symptoms vary according to the severity of dryness, but skin can be tight and rough and/or prone to itching, scaling, flakiness and redness. In extreme cases, skin is pathologically dry”.

The main reason for skin dryness is an impaired skin barrier function which results from:

What are the active ingredients in the formula?

“The development process started with Urea,” says Dr Filbry. “As an NMF, Urea helps skin to regulate its moisture content and, being a natural skin compound, it is well-tolerated even by dry and sensitive skin,” he adds. Urea is hydroscopic, which means it is able to bind moisture in to the external layer of skin. But this isn’t its only benefit. “Urea is keratolytic, meaning it breaks down the connections between dead skin cells,” explains Dr Filbry. “Urea is a key ingredient in Eucerin UreaRepair PLUS and, as part of our formulas, it improves natural skin exfoliation and soothes and smooths the surface of dry skin.”

The story behind Eucerin UreaRepair PLUS

“In the 1990s, Eucerin skin scientists were the first to discover how to include a Natural Moisturizing Factor in a dermo-cosmetic product”, says Dr Filbry. They created a product which was not only effective in terms of results but also pleasant to use. The Natural Moisturizing Factor (or NMF) they used was Urea and it has gone on to become one of the most respected and widely used ingredients in the treatment of dry skin symptoms.

“People who suffer from dry skin need more than just immediate relief,” explains Dr Filbry. “They need a long-term solution which will prevent symptoms such as roughness, itchiness and flakiness from returning.” Dr Filbry and his team set out to create an effective range of products that would deliver both immediate and long-lasting relief for dry, very dry and extremely dry skin.
