On the subject of skincare, we frequently get caught up in the newest TikTok trends and experimenting with trendy ingredients like witch hazel, forgetting that skincare is ultimately a science. Our skin’s job is to guard us — it acts as a barrier to guard the body from external aggressors reminiscent of bacteria, pollution, and UV rays. But, as we routinely use products like harsh chemical exfoliants, we may inadvertently harm our skin barrier.

The skin barrier is the outermost layer of the skin (also referred to as the epidermis) that guards against external stressors. When not properly protected “the skin barrier can begin to crack, which may leave the skin more vulnerable to free radical damage,” Florida-based board-certified dermatologist Lesley Clark-LoeserMD, tells Allure.

To be much more specific, “our skin barrier gets damaged from extreme weather, sun exposure, medical conditions, physical damage reminiscent of over-exfoliating, and in addition age,” explains board-certified dermatologist Do not know SaediMD, who relies in Plymouth Meeting, Pennsylvania. “Over time, ingredients like alcohol and glycolic acid could be abrasive to the skin if overused.” Dr. Clark-Loeser’s number-one tip? Go easy on the exfoliation — try simplifying your skin-care routine —  with the intention to maintain a healthy skin barrier. Moreover, the skin barrier can grow to be damaged by frequent hot showers, not using a moisturizer, and certain medications, so take note.

One other technique to maintain a healthy skin barrier is so as to add a barrier repair product, that are strategically formulated to deal with the particular needs of the skin barrier, to your routine. Where traditional moisturizing products provide supplemental hydration to the skin, “barrier repair products help to repair the skin’s barrier to assist skin higher retain moisture and stop environmental damage,” explains Dr. Clark-Loeser. For those who’re unsure what ingredients to search out in a barrier repair cream, San Diego-based board-certified dermatologist Melanie PalmMD, previously told us to search for “ingredients like glycerin, hyaluronic acid, squalane, natural moisturizing aspects, and ceramides.”

But how often should one apply a barrier repair product? On the subject of using barrier repair products, consistency is essential. Our experts beneficial applying the product not less than once a day, ideally after cleansing, to assist reinforce the skin’s natural protective barrier and keep it hydrated. For those with particularly dry or damaged skin, using the product twice each day could be helpful in helping to revive and maintain the skin’s health. Just remember, it is vital to make use of the product as directed and never overuse it, as this may result in further irritation.
