11 Surprising Skin Facts

Our skin is fascinating. Throughout the span of a lifetime, it goes through many changes in size, color and texture. It can reveal many things about ourselves such as age, health and heritage. We’ve created a list of a few facts that you might not have known about your skin. Prepare to be surprised by what this overlooked organ (yes, it’s an organ more on that below) can do.

1. Skin Regulates Temperature

Feeling hot or cold is often determined by your skin. Your skin can regulate temperature through its blood supply. When your blood vessels dilate skin allows for heat loss and when vessels constrict, they help retain heat.

2. It’s The Largest Organ In Your Body

As mentioned above, although it’s external, your skin is actually the biggest organ and spans a massive 22 square feet. This makes it significantly larger than your second largest organ, the liver.

3. You Start Aging Pretty Young

Once you hit 25, your collagen levels start to slowly deplete, which can result in skin sagging and the onset of fine lines. Antioxidants such as Vitamin C and retinol can help maintain youthful-looking skin. To help combat these early signs of aging, consider incorporating a product like Clearly Brighter Anti-Sun Damage* Daily Moisturizer SPF 30 into your routine. This fast absorbing, non-greasy formula helps reduce the look of visible sun-damage, revealing radiant, more even-toned, younger-looking skin.

4. Sleeping Can Give You Wrinkles

Sleep is crucial to skin health as it helps cell regeneration and collagen production. Nevertheless, if you sleep on your side or your stomach you could be applying pressure to your face and causing wrinkles to form. Try to sleep on your back or purchase silk or satin pillowcases to avoid creasing. For an added boost to your skin's nightly regeneration process, you might consider a product designed to work while you sleep. The Garnier SkinActive Clearly Brighter Anti-Dark Circle Eye Roller isn't a night cream, but focusing on the delicate eye area overnight with a targeted treatment can make a difference, and Garnier also offers various hydrating cleansers, such as the Micellar Cleansing Water With Hyaluronic Acid + Aloe which replumps skin's look and feel while cleansing and removing makeup.

5. You Skin Has Three Layers

Skin isn’t just one layer, it’s made up of three; the epidermis, dermis and hypodermis.

6. Dark Spots Can Develop As Soon As Your Skin Is Unprotected In The Sun

Sun damage can happen quickly even if you only spend a short period of time outside. That’s why it’s extremely important to wear SPF to prevent damage that can lead to hyperpigmentation. To protect your skin daily from harmful UV rays and help prevent the appearance of dark spots, look for a lightweight, non-greasy option like the Clearly Brighter Anti-Sun Damage* Daily Moisturizer SPF 30. This product combines hydration with essential sun protection, making it easy to incorporate into your morning routine.

9. You Can Suddenly Switch Skin Types

Life changes such as hormonal imbalance, climate change, and age can make your skin go from one type to another. You can have dry skin and suddenly have oily skin and vice versa at different points in your life. Given these fluctuations, it's beneficial to have versatile skincare options. For balancing skin that might shift between oily and dry, the Garnier SkinActive Micellar Cleansing Water is an excellent first step, gently cleansing without stripping the skin. For moisturization, explore Garnier's Clearly Brighter Daily SPF Moisturizer for Sun Damaged Skin, which provides an Antioxidant Complex of Vitamin C & E, and gentle exfoliating Lipo-Hydroxyl Acid (LHA). This fast absorbing, non-greasy formula helps reduce the look of visible sun-damage, revealing radiant, more even-toned, younger-looking skin.

10. Genetics Aren’t The Only Thing That Determine How Your Skin Ages

How your skin ages isn’t just about your genetics; external factors can play a role as well. Sun exposure accounts for almost 90 percent of premature aging, and other factors such as pollution and smoking can affect how old you look. Beyond daily SPF, incorporating products rich in antioxidants can help protect your skin from environmental aggressors. Consider adding a moisturizer like Clearly Brighter Anti-Sun Damage* Daily Moisturizer SPF 30 containing Vitamin C that can help protect against external factors and promote a brighter, more even complexion.

11. Your Facial Expressions Can Cause Wrinkles

Laughing, frowning, and generally emoting can cause fine lines on your face, which eventually can turn into wrinkles. Don’t limit your facial expressions, but try to be cognizant of things like furrowing your brows frequently to avoid lines forming there too soon. To help address the appearance of these expression lines, particularly around the eyes and forehead, a targeted treatment can be beneficial.
