Sensitive skin is one of the most common skin concerns today — redness and flushing during season changes, stinging from skincare products, dryness and flaking with temperature shifts, and even visible capillaries. The root cause is a damaged skin barrier. Over-cleansing, frequent exfoliation, improper acid use, and environmental pollution break down the brick-and-mortar structure of the stratum corneum. Seoul’s Rappoel Dermatology uses Rejuran PDRN injection to repair the damaged skin barrier at the cellular level, strengthening stratum corneum density and restoring healthy skin resilience.
Sensitive Skin Symptoms and Causes
- Primary Symptoms: Easy redness, stinging, dryness, flaking, tightness, intolerance to skincare products
- Barrier Damage: Reduced intercellular lipids in stratum corneum, increased transepidermal water loss (TEWL)
- Over-skincare: Frequent exfoliation, high-concentration acids, overly strong cleansers damage the barrier
- Environmental Factors: UV rays, air pollution, temperature swings, air-conditioned dry environments
- Post-Aesthetic Damage: Skin becomes thin and sensitive after excessive laser or chemical peels
- Genetic Factors: Some people naturally have thinner stratum corneum with weaker barrier function
How Rejuran PDRN Repairs Sensitive Skin
- Barrier Rebuilding: PDRN promotes keratinocyte proliferation and differentiation, increasing stratum corneum thickness and density
- Lipid Repair: Stimulates ceramide, cholesterol, and free fatty acid synthesis to repair intercellular lipids
- Anti-inflammatory: Inhibits inflammatory cytokine release via A2A receptors, reducing redness and stinging
- Vascular Stabilization: Strengthens capillary wall density, reducing visible redness and telangiectasia
- Collagen Production: Promotes dermal collagen production, increasing skin thickness and elasticity
- Cellular Repair: Activates DNA repair mechanisms, accelerating recovery of damaged cells

Daily Sensitive Skin Management Tips
- Gentle Cleansing: Use amino acid cleanser, water temperature 32-34 degrees, no more than 30 seconds
- Minimal Skincare: Keep only cleanse, moisturize, protect steps; pause all acids and brightening products
- Barrier Repair: Choose repair creams with ceramides, centella asiatica, panthenol
- Strict Sun Protection: Primarily physical (hat, umbrella), supplemented with gentle physical sunscreen
- Avoid Irritation: No scrubs, no facial steaming, no frequent sheet masks
Rejuran sensitive skin repair’s core advantage is addressing barrier issues at the cellular level rather than superficial symptom relief. PDRN not only repairs existing damage but also enhances long-term skin tolerance, gradually restoring your ability to use normal skincare products. Rappoel Clinic is located 3 minutes from Gangnam Station Exit 10, where doctors create personalized courses based on your sensitivity level and provide complete post-treatment care guidance.
