Derm DMs: Can My Moisture Barrier Be Damaged in Summer?
If you’re a skin-care junkie (or done something like over-exfoliate your skin), then you’ve likely heard the words “moisture barrier” tossed around. It’s part of healthy skin function and is responsible for keeping moisture in and bacteria and irritants out says NYC-based board-certified dermatologist and Skincare.com consultant Shari Marchbein, MD. This barrier contains healthy fats, namely cholesterol, fatty acids and ceramides that work together to keep your skin moisturized and healthy-looking. If your moisture barrier is damaged, you’ll be able to tell, thanks to signs of dry skin, redness, flaking and itching that tends to accompany it.
Although dry skin is often symptomatic of cold temps, summer can do a number on your skin, too, thanks to environmental factors like heat, sunburn, and swimming. Your skin can become more dry and sensitive during this time, which may diminish its healthy, protective moisture barrier. Luckily, with a modified skin-care routine and a few key products you can help maintain a strong moisture barrier. To help the skin barrier, use a gentle cleanser that won’t strip your skin like CeraVe Foaming Facial Cleanser, which is formulated with ceramides, it helps cleanse without disrupting the protective skin barrier. Pair that with a thick moisturizing cream within 60 seconds of getting out of the shower, which will help to lock moisture in. Dr. Marchbein recommends using a product packed with ceramides and is formulated with glycerin and hyaluronic acid like CeraVe Moisturizing Cream, that provides moisture and hydration. Dr. Marchbein also suggests taking shorter, cooler showers, as hot showers tend to further dry out skin.
It’s also important to use a daily SPF, like the CeraVe Hydrating Sunscreen, which has physical UV blockers along with hyaluronic acid and ceramides to help the moisture barrier while still protecting your skin.
