Skin Protection & Repair

The skin protective barrier function is assessed by measuring Trans-Epidermal Water Loss (TEWL) with the Tewameter®.

A compromised protective barrier will not preserve the natural hydration of the skin and it will not provide an effective skin protection. In such a situation, the measured water loss or TEWL rates will increase.

Topical products may aim to protect the integrity of the skin barrier against environmental stress or to repair the barrier.
