4 Fascinating Facts You Probably Never Knew About Your Skin

1.Your Skin Is Hiding a (Not So Great) Secret

Hopefully, you’re diligent about applying a broad-spectrum sunscreen daily now, but there may have been a time in your past when you were not so careful — and those habits may catch up to you. While you may not be able to see it in the mirror, UV photos can reveal the sun damage simmering beneath your skin.

2.Similar to a Snake That Sheds, Your Skin Renews Itself Every 28 Days

The epidermis is the thin outer layer of your skin, which contains dead skin cells. It’s this epidermis that turns over every 28 days, says Dr. Anolik. Another way to put it is that as skin cells generate at the bottom of the epidermis, it takes them about a month to reach the surface as dead cells naturally slough off, according to the American Skin Association.

3.Dry Skin in the Winter Isn’t Only Uncomfortable — It May Be Harmful, Too

When temperatures begin to dip in the winter, harsh winds and indoor heating systems can suck the moisture right out of your skin. Having a lizardlike texture to your skin is one thing, but the issue doesn’t end there. It can also increase our risk for infection with bacteria, viruses, and fungi. So, keep skin moisturized with products that contain hyaluronic acid, glycerin, or ceramides. Apply these within the first minute of coming out of the shower when skin is still moist, which will increase penetration and lock in hydration.

4.Changes in Your Skin Can Reflect Underlying Health Issues

Stress isn’t the only thing that can trigger a response from your skin. Many conditions and infections can cause changes in your skin, whether they take the form of a rash, hives, itching, redness, or swelling. For example, according to the American College of Allergy, Asthma, and Immunology, eczema, hives, and contact dermatitis can all indicate an allergic reaction. The AAD notes that adult acne can occur due to fluctuating hormone levels, which could indicate pregnancy, perimenopause, or menopause, but acne can also indicate a hormonal disorder such as polycystic ovary syndrome, according to the Mayo Clinic.
