"Skin cleansing is not just about purifying, but about maintaining a healthy and balanced skin structure by protecting the skin barrier."
HOW SHOULD SKIN CLEANSING BE? THE IMPORTANCE OF PROTECTING SKIN BARRIER

The Importance of Skin Cleansing

Skin cleansing is not only about removing dirt and makeup residues accumulated during the day but also plays a crucial role in maintaining long-term skin health. However, not all cleansing practices are skin-friendly. Using harsh products or aggressive methods can damage the skin's most valuable shield—the skin barrier—leading to dryness, sensitivity, and various skin issues over time. So what exactly is the skin barrier, and how can we protect it? Let’s explore together.

What Is the Skin Barrier?

Located in the outermost layer of the skin, the stratum corneum is a remarkable defense system composed of cells surrounded by lipids (such as ceramides, cholesterol, and fatty acids).
Its main functions are:
  • Retaining moisture within the skin
  • Blocking the entry of environmental irritants, allergens, and microorganisms

However, harsh chemical cleansers can disrupt this delicate structure, resulting in dryness, flakiness, and inflammation.

Remember: A healthy skin barrier is not only the secret to a smooth appearance but also to a radiant, vibrant, and balanced complexion.

How Do Chemical Cleansers Affect the Skin Barrier?

Many modern cleansing products—especially those with high pH, sulfates like SLS/SLES, and alcohol-based formulas—can disturb the skin's natural oil balance.

These products:

  • Dissolve the protective lipids on the skin surface
  • Weaken the barrier
  • Leave the skin vulnerable to external aggressors

As a result, issues such as dryness, tightness, sensitivity, and acne may occur.

What Should We Pay Attention to During Skin Cleansing?

  • Choose Gentle Formulations:

Opt for cleansers with a low pH (5.0–5.5) to support the skin’s natural pH and barrier function. Look for sulfate-free cleansers enriched with hydrating ingredients and natural aromatherapy oils that suit your skin type.

  • Avoid Overcleansing:

Tailor your cleansing routine to your skin’s needs. Cleaning more than twice a day may strip the skin’s natural protective oils. If you wear makeup or use sunscreen, cleanse twice a day; otherwise, once a day—morning or evening—is often enough.

  • Mind the Water Temperature:

Extremely hot water won’t kill bacteria, and extremely cold water won’t suddenly tighten your skin. Both can damage the skin barrier. Always opt for lukewarm water to help cleanse without disrupting the skin’s lipid layer.

  • Repair After Cleansing:

Instead of applying acidic products immediately after cleansing, focus on hydrating and repairing the skin. Prioritize postbiotic ingredients (byproducts of fermented probiotics that support the skin microbiome), which help strengthen the skin barrier. Additionally, clean formulas containing ceramides, niacinamide, and plant oils like sesame or pomegranate seed oil support barrier repair.

What Should a Skin Barrier-Friendly Cleansing Routine Look Like?

Morning:

  • Simply rinse your face with water or use a mild cleanser suitable for your skin type.
  • Before applying sunscreen or makeup, use a lightweight, alcohol-free, preferably postbiotic-infused moisturizer to support your skin barrier.

Evening:

  • If you’ve used sunscreen or makeup, double cleansing is essential. Start with an oil-based cleanser to deeply remove product build-up, then follow with a gentle, pH-balanced water-based cleanser.
  • After cleansing, apply a barrier-repairing moisturizer.

Is Cleansing Just About Removing Dirt?

No, cleansing is not just about removing impurities—it’s about maintaining balance. Choosing barrier-friendly products over harsh chemical cleansers protects your skin’s natural defense system and promotes a healthier appearance over time. Cleansers formulated with skin-friendly ingredients like botanical oils, postbiotics, and ceramides not only cleanse but also nourish the skin. By choosing products with cleaner, gentler ingredients, you can build a skincare routine that supports your skin rather than stressing it.
