Indications

Acne scar or chicken pox scar, superficial traumatic scar, superficial tattoo.

Operation purpose

To make the new epidermis smooth by removing the lesion with a dermabrasion machine.

Notes after surgery

• Use dressings or artificial skin as directed: As there are more exudates 1 to 3 days after operation, more changes need to be done. After the wound is cleaned and wiped with normal saline solution, the artificial skin 1-2cm larger than the wound is affixed. After 4 to 8 days of wound healing, exudation decreases. If the artificial skin is affixed with no exudate for 24 hours, it can be discontinued.
• Stimulant foods such as tobacco, alcohol, coffee and chilies are prohibited.
• Wash your face with warm water and non-irritating cleanser.
• Apply sunscreen at SPF30 or above and moisturizing products when you go out. Wear a hat and put up a parasol to protect your skin from pigmentation. Sunscreen still needs to be applied indoors, as sunlight can penetrate glass and cause damage to the skin. New skin should not be exposed to sunlight for 3 months.
• The new skin is pink and will return to normal within 3 to 6 months.

Post-Surgery Care Instructions

• Wound Cleaning and Protection:
• Use of Dressings or Hydrocolloid Bandages: Gently clean the wound with sterile cotton swabs dipped in normal saline. After cleaning, apply a hydrocolloid bandage or dressing cut to be 1–2 cm larger than the edges of the wound.
• Changing the Dressing: During the first 1–3 days post-surgery, exudate (fluid) levels are higher, requiring more frequent changes. From days 4–8, as the wound heals, the fluid will decrease. If there is no leakage after the hydrocolloid bandage has been applied for 24 hours, you may stop using it.

• Environment: For one week after surgery, avoid high-temperature or humid environments, hot springs, strenuous exercise, and extreme heat to prevent sweat from irritating the wound or worsening swelling and redness.
• Skincare Restrictions: Before the wound is fully healed (approximately within 7–14 days), do not use irritating skincare products containing alcohol, AHAs (fruit acids), Retin-A (Tretinoin), whitening agents, or fragrances.
• Cleansing: Use lukewarm water and a non-irritating facial cleanser to wash your skin.

• Diet:
• Avoid irritants such as smoking, alcohol, coffee, and spicy foods for 1–2 weeks after surgery.

• Sun Protection:
• UV Protection: New skin is extremely fragile and susceptible to UV damage, which can lead to hyperpigmentation (darkening). For three months after the wound has healed, you must use sunscreen with SPF 50 or higher and utilize physical protection such as umbrellas and hats.
• Indoor Protection: Sunscreen should still be applied indoors, as sunlight can penetrate glass and damage the skin. Avoid direct sunlight on the new skin for 6–8 weeks.
• Long-term Care:
• Redness: Redness of the skin may persist for 3–6 months. Use a gentle skincare routine and enhance hydration with products containing hyaluronic acid, moisturizing creams, or repair-focused ingredients.
• Makeup: You may apply makeup once the wound has completely healed. Choose products with simple ingredients that are free of fragrance and alcohol.
