We tend to think of exfoliation simply as removing dead skin cells from the surface. And while that is part of what it does, exfoliation can offer benefits beyond simply making the skin feel smoother. Depending on the type of exfoliation, it can help improve texture and luminosity, keep pores clear, support skin renewal, and address some of the visible changes we associate with aging and sun damage. The key isn't simply to exfoliate more. It's to understand why you're exfoli

1. Hyaluronic Acid This ultra-effective ingredient has a host of anti-aging benefits because of its ability to retain water. Each molecule of hyaluronic acid (HA) attracts multiple times the amount of its weight in water, meaning moisturizing products that contain HA are incredibly effective. Those with dry skin or who live in harsh climates can greatly benefit from products that contain hyaluronic acid. Additionally, all skin types can use products with HA, unless a specific

We hear so much about collagen in skin care. Collagen creams, collagen serums, collagen supplements, and treatments that promise to boost collagen. Elastin doesn't get quite as much attention, but it is just as important when we're talking about how our skin changes as we age. So what are collagen and elastin, why do we lose them, and most importantly, can we actually put them back? Collagen and Elastin: What's the Difference? Collagen and elastin are proteins that make up an

Many people want brighter, healthier-looking skin, but with so many skincare products on the market, it can be hard to know what's actually worth your investment. If there is one product I routinely recommend adding to a skincare routine, it's a Vitamin C serum. What does Vitamin C do? Protects against oxidative stress by neutralizing free radicals caused by pollution, UV exposure, and environmental stress. Brightens and evens skin tone for a more radiant complexion by redu

Your skin is often a reflection of your overall health. While a good skincare routine is essential, healthy skin isn't just about the products you apply—it's also influenced by the foods you eat. The nutrients in your diet provide the building blocks your skin needs to repair itself, produce collagen, maintain hydration, and support a healthy skin barrier. Although no single food can erase wrinkles or cure acne, eating a balanced, nutrient-rich diet can help reduce inflammati

Menopause brings significant changes to your skin, largely due to a decline in estrogen. This hormone plays an important role in keeping skin healthy by supporting collagen production, natural oil production, hydration, and skin repair. As estrogen levels decrease, your skin produces less collagen and oil, making it more difficult to retain moisture, repair itself, and maintain a strong, healthy skin barrier.You may notice: Thinner, drier, and less elastic skin Drier, rougher

When we think about healthy, glowing skin, we often focus on the products that feel the most “active”—serums, moisturizers, masks, and treatments. But the truth is, healthy skin starts with one simple step: cleansing. Clean skin is healthy skin. You’ve heard me say that a hundred times! Cleansing is more than just washing your face. It is the foundation of your entire skincare routine. A good cleanser removes makeup, sunscreen, excess oil, pollution, and daily buildup, while

Dry skin can have different causes, and each one requires a slightly different approach. Knowing the difference can help you build a skincare routine that gives your skin what it truly needs. Dry skin type: Some people are born with skin that produces less oil. If you have a naturally dry skin type, your skin will always need extra nourishment and support. Dry skin condition: Even if your skin isn't naturally dry, it can become dry temporarily. Weather, harsh cleansers, over-

We spend so much time focusing on what to put on our skin, but often overlook one of the most important factors in healthy, radiant skin: when we use it. The truth is, nighttime is when the real magic happens. During the day, your skin is in defense mode—protecting itself from UV rays, pollution, makeup, sunscreen, excess oil, and environmental stressors. But once you drift off to sleep, your skin shifts gears. Instead of defending, it focuses on repair, renewal, and recovery

Aging is a natural process, and the lines on our faces tell the story of every laugh, smile, and expression we share. However, understanding how our skin changes empowers us to give it the exact support it needs to stay strong, plump, and resilient. Here is what is happening beneath the surface, and exactly how we can protect it from the outside in—and the inside out. The Science: Why Skin Structural Changes Happen Starting in our 20s, the skin’s natural renewal processes sl

Imagine a single mineral that acts as the master conductor for your entire body—quietly directing everything from how deeply you sleep to how steadily your heart beats. That powerhouse is magnesium. While it often flies under the radar compared to more widely discussed nutrients, magnesium is an essential mineral involved in over 300 biochemical reactions that keep your body functioning at its best. Yet despite its importance, research suggests that nearly 45%–68% of U.S. adu

Eve Mérinville | Comfort Zone Corporate RD Excellence & SC RD and Innovation Director ow Collagen Affects Your Body Sk Your skin is your body's largest organ. It deserves to be protected and nourished. And when we consider collagen, we're talking about the deep support system that helps the skin feel stronger, appear firmer, and remain resilient over time, through seasons, stress, and change. Have you ever wondered what collagen does for the skin of our body? Collagen helps t

By understanding your skin type and recognizing your current skin conditions, you can choose the right ingredients to target your specific concerns. Whether it’s hydration, brightening, soothing, or anti-aging, a tailored routine makes all the difference in keeping your skin healthy, balanced, and glowing. Here are some more details. Skin Type vs. Skin Condition Skin Type is what you’re born with. It’s your skin’s baseline behavior and generally stays the same over time. Com

The skin can mirror what is happening internally. Cortisol is often called the body’s primary stress hormone. It’s released when we’re under emotional stress, poor sleep, overworking, illness, or feeling constantly “on alert.” While cortisol is important in short bursts, chronically elevated cortisol can become inflammatory and disruptive throughout the body—including the skin. Stress also impacts circulation, sleep quality, digestion, and hormone balance—all of which influen

When it comes to healthy, beautiful skin, there is one thing that should always come first: a strong, healthy skin barrier. The outermost layer of your skin—often called the skin barrier, moisture barrier, lipid barrier, or acid mantle—works around the clock to protect you. It's made up of skin cells held together by a mixture of ceramides, cholesterol, fatty acids, and other lipids that act like mortar between bricks. What Does the Skin Barrier Do? Your skin barrier has seve
