When it comes to keeping UV rays, pollutants, microbes, and other environmental nasties from finding their way inside your body, there’s no better defense than your skin barrier.

Not only does it play the essential role of keeping the bad stuff out, but it also does the equally important job of keeping hydration in so that your skin stays soft, supple, and strong.

While it’s nice to know someone’s always got your back, your skin barrier needs a little help from you to maintain its integrity and do its job correctly.

Today, we’ll explain what the skin barrier is, including its “brick and mortar” structure, how you can recognize signs of damage, the dos and don’ts of proper care, and a few of Dr. Briden’s dermatologist-recommended skincare faves for improving barrier health.

The Science Behind Your Skin’s First Line of Defense

You may have been taught in anatomy class that the epidermis is the outermost layer of skin, but did you know it’s further split into four or five layers?

The outermost of these layers- the stratum corneum- is what we often refer to as our skin, lipid, or moisture barrier. It comprises many layers of brick-like corneocytes, tough skin cells held together by a lipid “mortar” composed of ceramides, cholesterol, and fatty acids.

These two components form a remarkably strong blockade against external risks while also playing home to a customized mix of yeast, viruses, and good bacteria that make up the skin microbiome. Your skin’s slightly acidic pH gives these florae a safe place to hunker down while keeping unfamiliar microbes from invading your skin to wreak havoc.

All these different pieces come together synergistically, and when everything’s in the correct proportions, it works like a well-oiled machine.

However, without the proper preventatives, something as small as a change in the weather can throw off this natural harmony and lead to a damaged skin barrier.

Signs of a Damaged Skin Barrier

With all of these powerful defenses in place, it might be a surprise that your moisture barrier is still susceptible to damage when its ingredients fall out of balance.

For example, a lack of ceramides or cholesterol makes it much more difficult for your skin to retain moisture, leading to flaky, dry skin.

When it’s fatty acids that you’re missing, your skin develops rough spots and has a tougher time repairing itself from minor injuries.

Throw off the pH balance, and your skin can’t fend off harmful bacteria or produce the amount of lipids needed to bind together corneocytes.

Keep an eye out for these early signs of a compromised skin barrier so you can take measures to restore it:

  • Sudden sensitivity to products you’ve used before with no problems
  • Redness
  • Dryness and flakes
  • Itchiness and irritations
  • Skin feeling tight and uncomfortable after cleansing
  • Increased breakouts and overproduction of oil
  • Uneven texture
  • Discoloration
  • Dullness

The Dos and Don’ts of Skin Barrier Health

They say the best offense is a good defense, and that goes double for keeping your skin barrier in balance. It’s much easier to maintain its health than it is to attempt to repair it once it’s already damaged, so use these dos and don’ts to help you make everyday choices that support your skin:


  1. Do keep your skin well-moisturized with quenching ingredients like hyaluronic acid, ceramides, and other humectants that maintain hydration.
  2. Do choose mild cleansers that won’t strip away your skin’s natural oils.
  3. Do incorporate skin-supportive foods into your diet, like those rich in fatty acids.
  4. Do protect your skin from harsh environmental dangers by wearing sunscreen and avoiding exposure to the elements.
  5. Do tailor your skincare routine to your specific skin type with the help of your dermatologist.


  1. Don’t ignore signs of skin stress. As soon as you suspect that your skin barrier is in danger, give it a little extra TLC to restore and renew it.
  2. Don’t over exfoliate. While it’s great for your skin health to slough off dead layers of stratum corneum once or twice a week, doing it too often saps away the lipids in your skin barrier.
  3. Don’t use products that are harsh on your skin, like alcohol and fragrances. Stick with dermatologist-recommended products that help keep your skin in balance.
