At Charleston Dermatology, our team truly knows skin inside and out, and we’re passionate about helping you look and feel your best at every stage of life. One of the most important, yet often overlooked, elements of skin health is the skin barrier. Caring for this essential part of your skin is vital for lifelong comfort and wellness.

What Is the Skin Barrier?

We often describe the skin barrier, or stratum corneum, to our patients as a brick wall. Think of your skin cells as sturdy bricks, while the “mortar” holding them together is made up of natural oils like ceramides, cholesterol, and fatty acids. Together, these form a shield that protects your entire body. This barrier works quietly behind the scenes to keep hydration and nutrients safely tucked into your skin and to hold off threats from the environment, such as pollution, harsh weather, or bacteria. When your barrier is functioning well, your skin feels supple, calm, and resilient.

Signs of a Damaged Skin Barrier

In our clinic, we see many patients experiencing discomfort that points to an impaired skin barrier. Signs that your barrier may be damaged include:

• Persistent dryness or flakiness
• Red or inflamed skin
• Increased sensitivity to skincare products
• Roughness, itchiness, or a dull skin tone

Sometimes, conditions you already have, such as eczema, rosacea, or acne, can flare up or become worse. If these issues sound familiar, you’re not alone. Most cases simply require a targeted, professional approach to get your skin back on track.

What Damages the Skin Barrier

Your skin barrier can be disrupted by a mix of environmental, routine-based, and internal factors. Sun exposure is a major culprit, breaking down the lipids and proteins that keep moisture in and irritants out. Pollution, allergens, and dry, cold, or windy weather add to the strain by triggering inflammation and accelerating moisture loss.

Daily habits can unintentionally make things worse. Over-exfoliating with strong scrubs or acids, using high-pH or stripping cleansers, and taking long, hot showers can all remove the protective oils your skin depends on.

Internal influences also play a role. Genetics and conditions like eczema can weaken the barrier from the start, while aging reduces natural lipid production. Even elevated stress levels can impact barrier function by increasing cortisol in the body.

How We Recommend You Repair and Maintain Your Skin Barrier

Our approach at Charleston Dermatology is to keep things simple and supportive, especially if your skin is struggling. If your skin barrier is compromised, pare back your routine to the basics.

Focus on a gentle cleanser, a moisturizer that supports the barrier, and daily use of a broad-spectrum sunscreen.

We encourage our patients to look for products with barrier-supporting ingredients. Some ingredients we recommend include:

• Ceramides, which help replenish the “mortar” in your skin’s wall
• Hyaluronic acid, which works as a magnet for moisture and provides deep hydration
• Niacinamide (vitamin B3), excellent for calming redness, strengthening your skin, and improving texture
• Glycerin to help lock in much-needed moisture
• Fatty acids, such as linoleic acid, which reinforce your skin’s structure
