How effective is laser treatment for removing acne scars?

Acne scars, also known as acne keloid scars. Generally speaking, the effects of laser scar removal include reducing scar area, relieving itching symptoms, improving appearance, promoting healing, and reducing recurrence rates. If necessary, it is recommended to undergo treatment under a doctor's guidance. Detailed explanations are as follows:

1. Reduce Scar Area

Laser treatment works through photothermal action, which can destroy microvessels within the scar tissue, reducing blood supply to the scar and thus inhibiting further scar proliferation.

2. Relieve Itching Symptoms

Acne scars may be accompanied by itching. Laser treatment helps reduce capillary dilation and excessive proliferation of keratinized cells, thereby decreasing the sensation of itching.

3. Improve Appearance

Laser therapy can stimulate regeneration of surrounding healthy tissue, achieving a smoothing effect and improving the appearance of scars, making their color closer to normal skin tone.

4. Promote Healing

The localized thermal effect induced by laser treatment improves blood circulation, promotes the formation of new blood vessels, and enhances nutrient supply during the tissue healing process, thus accelerating recovery.

5. Reduce Recurrence Rate

Acne scars themselves are highly proliferative and prone to recurrence. Laser treatment can reduce the recurrence rate to some extent and help the scar tissue return to a healthier state more quickly.

Proper post-treatment care and sun protection measures are also essential after laser treatment to avoid compromising the healing outcome.
