Skin Barrier Function

Keeping our skin barrier healthy is much more than a cosmetic concern. Our skin barrier is our body’s frontline defense against everything the world throws at us.

Also known as the stratum corneum, our skin barrier helps limit Trans-Epidermal Water Loss (TEWL) by sealing in moisture and hydration, and acts as a barrier providing protection from environmental toxins and harmful microorganisms such as bacteria, fungi, and insects. It also stores important enzymes, hormones, and cytokines, as well as provides antioxidant and immune support.

A thin, weak skin barrier lets irritants in and moisture out, resulting in dullness, dryness, and sensitivity that can lead to inflammation and premature aging.

Things that cause skin barrier damage:

  • The natural aging process

  • UV exposure

  • Pollution

  • Blue light

  • Stress

  • Bacteria

  • Poor diet

  • Harsh chemical skincare

  • Over cleansing

  • Over exfoliating

  • Extreme temperatures

  • Genetic skin conditions

Symptoms of a compromised skin barrier/barrier function:

  • Dryness

  • Dehydration

  • Redness/inflammation

  • Flakiness

  • Irritation and/or sensitivity

  • Itchiness

  • Rough or discolored patches

  • Bacterial, fungal, or viral skin infections

How can you protect the barrier function of your skin?

  • Simplify your skincare routine

  • Keep your skin's pH in check

  • Apply plant oils

  • Use a hyaluronic acid serum

  • Wear sunscreen

  • Keep hydrated - inside and out

  • Take it easy on the exfoliators

  • Use moisturizer

  • Get professional facials regularly

  • Use skincare products that are rich in antioxidants and that are appropriate for your skin type and condition.
