How to repair damaged skin stratum corneum
In recent years, with the improvement of skin care awareness, more and more people have begun to pay attention to skin barrier health issues. The stratum corneum is the skin's first line of defense. Once damaged, it can lead to problems such as dryness, sensitivity, and redness. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the causes and repair methods of cuticle damage.
1. Common causes of stratum corneum damage

| Reason | Description |
|---|---|
| excessive cleaning | Frequent use of soap-based cleansers or makeup removers damages the sebum film |
| Excessive exfoliation | Frequent use of scrubs and acid products (such as alcohol, salicylic acid) |
| environmental factors | External stimuli such as ultraviolet rays, dryness, and pollution |
| Improper skin care | Use skin care products containing irritating ingredients such as alcohol and fragrances |
2. Symptoms of damaged stratum corneum
| Symptoms | Specific performance |
|---|---|
| Dry and flaky | Tight, flaky skin, poor absorption of moisturizing products |
| redness sensitivity | Prone to redness and stinging when exposed to cold or heat or skin care products |
| Decreased barrier function | More susceptible to external stimulation, triggering inflammatory response |
3. Four major steps to scientifically repair the stratum corneum
1. Gentle cleansing
Choose amino acid or APG surface-activated cleansers, and control the water temperature at 32-34°C to avoid excessive friction. Recently popular ingredients: glucoside (APG), betaine.
2. Supplement lipids
| Restorative ingredients | Mechanism of action |
|---|---|
| Ceramide | Accounts for 50% of stratum corneum lipids and rebuilds intercellular matrix |
| cholesterol | Promote normal metabolism of keratinocytes |
| fatty acids | Enhance skin's ability to retain moisture |
3. Enhance moisturizing
Recent popular repair combinations:
- B5 Panthenol + Hyaluronic Acid (Hydrating)
- Squalane + Shea Butter (lock in moisture)
Note: Avoid moisturizing products containing alcohol and fragrance.
4. Sun protection
Choose physical sunscreen (zinc oxide/titanium dioxide), SPF30-50, and reapply every 2 hours. Hot new product: Repairing sunscreen containing centella asiatica.
4. Repair cycle reference
| repair stage | time | Nursing focus |
|---|---|---|
| acute phase | 1-2 weeks | Disable functional products and only perform basic repairs |
| recovery period | 3-8 weeks | Return to a simple skin care routine step by step |
| Consolidation period | 8 weeks+ | After establishing tolerance, introduce advanced care such as antioxidants |
5. List of recent popular repair products
| product type | Representative products | core ingredients |
|---|---|---|
| repair cream | La Roche-Posay B5 | Panthenol + Madecassoside |
| essential oil | LAN time oil | Ceramide + Squalane |
| facial mask | Winona Shumin | Purslane Extract |
Things to note:
1. During the repair period, avoid wearing makeup, exfoliating, applying acid, etc.
2. If severe allergies occur, seek medical attention promptly.
3. Supplement Omega-3 (deep-sea fish, flaxseed oil) with your diet
4. Ensure adequate sleep (go to bed before 23:00) to promote skin self-repair
Through systematic care, most people's stratum corneum can be significantly improved within 1-3 months. Remember: "less is more" during the repair period. Giving the skin enough time to recuperate is the key.
