Introduction
In general, post-acne hyperpigmentation can be treated through regular skincare, medication, laser therapy, photorejuvenation, or chemical peels. It is recommended to perform these treatments under the guidance of a qualified physician to ensure safety and proper procedure. When going outdoors, it is advisable to use sun umbrellas or wear sun hats to avoid UV exposure, which may worsen pigmentation.
In general, post-acne hyperpigmentation (dark marks) can be treated through regular skincare, medication, laser therapy, photorejuvenation, and chemical peels. It is recommended to perform these treatments under the guidance of a professional doctor to ensure safety and proper procedure. Specific methods are analyzed as follows:
1. Regular Skincare
Cleanse the face morning and evening with a gentle facial cleanser to remove oil and dirt. Use skincare products suitable for your skin type to moisturize and repair the skin. Products containing ingredients such as vitamin C and arbutin are recommended.
2. Medication
Under a doctor's supervision, topical medications such as Madecassol cream, hydroquinone cream, or adapalene gel may be used to promote skin recovery. These medications help inhibit melanin production and accelerate pigment metabolism, thereby lightening acne marks.
3. Laser Therapy
Laser therapy uses light energy and heat to target the dermis layer of the skin, breaking down pigment particles beneath the surface and improving dark acne marks. The typical cost for laser treatment ranges from 500 to 3,000 yuan per session. Noticeable improvement usually appears within 2–4 weeks, although side effects such as skin swelling or pigmentation may occur.
4. Photorejuvenation (Intense Pulsed Light, IPL)
Photorejuvenation uses broad-spectrum colored light to break down and metabolize acne marks while stimulating new cell regeneration to repair the skin. The typical cost ranges from 1,000 to 5,000 yuan per session. Improvement is generally seen within 2–4 weeks, though side effects such as redness and stinging may occur.
5. Chemical Peel (Glycolic Acid Peel)
Chemical peeling uses high-concentration glycolic acid to exfoliate the outer skin layer, accelerate epidermal cell turnover, and reduce pigmentation. The typical cost ranges from 1,000 to 3,000 yuan per session. Improvement is usually visible within 1–2 weeks, though temporary side effects like redness and peeling may occur.
When going outdoors, it is advisable to use an umbrella or wear a sun hat to avoid UV exposure, which can worsen pigmentation. Additionally, reducing intake of spicy, greasy, and other irritating foods, along with ensuring sufficient sleep, benefits overall skin health.
