Why Does Sensitive Skin Turn Red?

🛡️ Damaged skin barrier

🔥 Overactive immune response

⚖️ Hormonal changes & stress

Causes of Sensitive Skin

Sensitive skin and redness often develop due to a combination of internal and external factors. Understanding these triggers is the first step in restoring balance and protecting the skin barrier.

Internal Factors
  • Genetic Factors — Congenital skin barrier weakness (e.g., thin stratum corneum, lack of lipids), making the skin easily irritated.
  • Immune System Disorders — Overactive immune response (inflammation triggered by allergens). Chronic inflammatory conditions (e.g., eczema, psoriasis) can reduce skin defense.
  • Neurogenic Sensitivity — Overactive nerve endings react strongly to external stimuli (temperature changes, friction), causing stinging, burning, or discomfort.
  • Hormonal & Endocrine Changes — During pregnancy, menstruation, menopause, or under stress, hormonal fluctuations may trigger skin sensitivity.
External Factors
  • Environmental Irritation — Climate: dryness, cold (reducing skin lipids), UV rays (damaging barrier), pollution (free radical damage). Seasonal changes: abrupt shifts in temperature/humidity may trigger reactions.
  • Improper Skincare Habits — Over-cleansing (frequent exfoliation, harsh cleansers). Excessive use of acids (retinoids, AHAs, BHAs) or alcohol-based products. Overuse of sheet masks, leading to barrier disruption.
  • Irritating Cosmetic Ingredients — Preservatives (e.g., phenoxyethanol), fragrances, colorants, or certain sunscreens (e.g., avobenzone).
  • Medication or Cosmetic Procedures — Long-term steroid use (causing dependency and dermatitis). Inadequate recovery after laser or invasive treatments.
  • Lifestyle Factors — Staying up late, stress (increasing cortisol, worsening inflammation). Diet: high sugar, spicy food, alcohol may trigger or worsen sensitivity.


Key Issue of Sensitive Skin

The root problem lies in a damaged stratum corneum and weakened skin barrier.

The core solution is barrier repair, focusing on:


Defense: Protect against bacteria, chemicals, UV, and pollution.

Moisture Retention: Prevent water loss, dryness, flakiness, and itching.


Functional Balance: Maintain healthy skin sensation, metabolism, and repair functions, avoiding pain, tightness, and abnormal reactions.
