How to Protect Your Skin’s Moisture Barrier When It’s Frigid Outside

Winter usually heralds in cozy traditions like family dinners and hot beverages. It also traditionally heralds dry, flaking, stinging—even splitting—skin. And while many of us will be remaining indoors for the winter, there’s still the problem of constant heater usage, which is bound to irritate and dry out our skin even more. If you’ve been slathering on oils and moisturizers to no avail, we ask you this: have you considered your skin’s moisture barrier? Keep reading to find out the key to keeping your skin hydrated and soothed even through the winter months.

Firstly: What is your skin’s moisture barrier?

“The moisture barrier is the protective layer of the skin filled with ceramides, fatty acids, and lipids,” according to dermatologist and Review2Coupon Review Board member Dr. Onyeka Obioha, MD. It can also go by the name of the acid mantle. “It functions as a shield against the harsh external environment and unwanted bacteria. It also absorbs and maintains moisture by preventing transepidermal water loss, which is dehydration of the skin.”

Many brands have come out with products specifically meant to help your skin’s moisture barrier, such as Lord Jones’ Acid Mantle Repair—a thick, goopy cream to help lock moisture back into the skin. “This vital barrier also retains moisture to maintain your skin’s hydration levels,” explains Lord Jones’ General Manager, Summer Frein. “A healthy acid mantle is slightly acidic, with a pH between 4.5 and 6.2. A depleted acid mantle makes your face more susceptible to irritants and future damage.” Many things can throw the moisture barrier out of balance, like changes in weather, face masks, overly acidic products, and UV exposure. Wintertime is a particularly vulnerable period of year for the moisture barrier. “Cold temperatures break down this protective layer, creating cracks in the skin, dryness and inflammation,” says Dr. Ohioba. “Indoor heaters decrease humidity levels, accelerating water loss from the skin and resulting in dryness. Those who suffer from chronic inflammatory skin conditions, such as eczema, are more likely to flare due to these moisture-stripping triggers.”

How can you tell if you have a compromised moisture barrier?

Well, the signs are pretty easy to see (and feel). Redness, dryness, itching and skin wrinkling are all signs of a compromised skin barrier. When my moisture barrier is compromised (usually due to using too many actives at once), I’ve experienced intense stinging at the slightest touch, skin looking shiny and tight, dehydration, persistent acne, and flaking. A healthy moisture barrier should hold onto moisture properly, and help your skin stay hydrated, plump and firm.

If your moisture barrier isn’t in the best shape, don’t worry! It just takes a little patience, carefully selected products, and consistency to bring it back to its prime.
