Black marks left after a leg injury can be treated with methods such as topical application of traditional Chinese medicine, laser therapy, microneedling, and dermabrasion.
1. External application of traditional Chinese medicine
Traditional Chinese medicine external application works by promoting local blood circulation and accelerating metabolism to lighten pigmentation. For example, ointments made from herbs such as angelica and angelica dahurica, which have the effects of promoting blood circulation, removing blood stasis, reducing swelling, and relieving pain, are applied to the affected area regularly. This is suitable for mild pigmentation, such as dark marks caused by bruising. Its effect on deeper dark marks may be limited.
2. Laser therapy
Laser therapy uses specific wavelengths of light to directly target the skin's surface, breaking down melanin granules. Common devices include Q-switched pulsed dye lasers and picosecond lasers. It is suitable for removing shallow melanin deposits and improving pigmentation. Multiple treatments are required, and sun protection is essential to prevent recurrence.
3. Microneedling therapy
Microneedling treatment stimulates the skin with tiny needles, promoting collagen regeneration and melanin metabolism. Common techniques include microneedling radiofrequency and microneedling rollers. It is suitable for improving pigmentation caused by trauma and can also improve skin firmness. Proper skin care is necessary before and after treatment.
4. Dermabrasion
Dermabrasion removes a portion of the epidermis using mechanical or chemical means, allowing new tissue to repair the damage. The procedure is usually performed under local anesthesia. It is suitable for deep pigmentation and scarring. Strict adherence to the doctor's instructions for recovery care is essential after the procedure.
When treating dark marks on the leg after an injury, avoid trying unsafe methods such as squeezing or rubbing the affected area, as this may worsen pigmentation or cause infection. It is recommended to seek advice from a professional doctor to choose an appropriate treatment method based on your specific situation.
