Purpose is defined as the reason for which something is done or created. Facial products are substances manufactured to perform a specific task for the face. So do you ever question the intention behind the facial products that you use and the science that supports its creation? Marketing in the cosmetics industry creates a hope in the next big ingredient that will solve everyone’s skin concerns. Reality check, it doesn’t work that way.
Back to the original question, my answer is that a good facial product prevents Trans Epidermal Water Loss (TEWL). Maintaining the water balance in the skin’s layers prevents premature aging. TEWL is the amount of water that passes from your skin layers to the surrounding environment. This process occurs due to diffusion and evaporation and we don’t have control over it because we can’t control our climate. We can only make adjustments (with facial product choices).
TEWL is influenced by trauma to the skin barrier such as burns and scratches or exposure to surfactants, and climate changes. Normal ranges of water in the skin is anywhere from 10 to 20%.
How to reduce TEWL:
- Protect the skin from too much sun or wind exposure
- Using Cleansers with mild surfactants
- Use Butters that act as occlusive agents
