How to lighten scars formed by melanin deposition?
Dear Dr.
Zheng,
I hope this message finds you well.
I would like to explain my situation: My skin type is prone to developing post-inflammatory hyperpigmentation, which appears as dark spots after minor scratches or eczema-related itching heals.
Even after six months, these spots have not faded, causing me significant distress.
I have a few questions for you:
1.
Is this condition related to my individual constitution? What specific nutrients should I supplement?
2.
What ingredients should I look for in skincare products or medications to apply?
3.
Since I live in Taipei, could you recommend any hospitals or doctors in the city who specialize in this type of issue for a thorough diagnosis?
Thank you very much for your assistance!
Best regards.

More Info
Hyperpigmentation, particularly post-inflammatory hyperpigmentation (PIH), is a common skin condition that can occur after injuries to the skin, such as scratches or eczema flare-ups. This condition is characterized by darkened areas of skin that remain even after the initial injury has healed. Your concerns are valid, and I will address your questions in detail.
1. Relation to Personal Physique and Nutritional Needs: Yes, individual skin types and genetic predispositions can significantly influence how your skin responds to injuries and how it heals. Some people have a tendency to develop hyperpigmentation more readily than others, often due to factors such as skin type (darker skin types are more prone to PIH), hormonal changes, and even certain medical conditions. As for nutritional supplementation, while there is no specific nutrient that guarantees prevention of hyperpigmentation, maintaining a balanced diet rich in antioxidants (like vitamins C and E), omega-3 fatty acids, and zinc can support overall skin health. Foods such as fruits, vegetables, nuts, and fish can be beneficial.
2. Topical Treatments: When it comes to fading hyperpigmentation, several active ingredients in skincare products can be effective:
- Hydroquinone: This is a skin-lightening agent that can reduce the appearance of dark spots. However, it should be used under medical supervision due to potential side effects with prolonged use.
- Retinoids: These are derivatives of vitamin A that promote cell turnover and can help fade dark spots over time. They can also improve skin texture and prevent new pigmentation from forming.
- Vitamin C: Known for its brightening properties, vitamin C can help inhibit melanin production and promote an even skin tone.
- Niacinamide: This form of vitamin B3 can help reduce the appearance of dark spots and improve skin barrier function.
- Alpha Hydroxy Acids (AHAs): Ingredients like glycolic acid can exfoliate the skin and promote the shedding of pigmented cells.
- Azelaic Acid: This is effective for both acne and hyperpigmentation, and it has anti-inflammatory properties.
It is essential to apply sunscreen daily, as UV exposure can worsen hyperpigmentation. Look for a broad-spectrum sunscreen with an SPF of at least 30, and reapply it every two hours when outdoors.
3. Professional Recommendations in Taipei: For personalized treatment, it is advisable to consult a dermatologist who specializes in pigmentation issues. In Taipei, you can consider visiting reputable dermatology clinics or hospitals such as:
- National Taiwan University Hospital: Known for its comprehensive dermatology department.
- Taipei Medical University Hospital: Offers specialized skin treatments and consultations.
- Private dermatology clinics: Many experienced dermatologists in Taipei focus on cosmetic dermatology and can provide tailored treatment plans for hyperpigmentation.
In summary, while hyperpigmentation can be frustrating, there are effective treatments available. A combination of topical agents, good sun protection, and possibly professional treatments like chemical peels or laser therapy can significantly improve your skin's appearance. Always consult with a healthcare professional before starting any new treatment to ensure it is appropriate for your skin type and condition.
