Can laser treatment flatten depressed scars?

　　Laser treatment for atrophic scars mainly utilizes the photothermal effect, directly penetrating into the subcutaneous tissue to stimulate collagen proliferation, thereby filling and flattening the scars. The general reference price for laser treatment of atrophic scars is 2500-7500 yuan per session, with visible improvement typically observed within 1-3 months. Laser treatment can usually flatten atrophic scars, but its effectiveness may be limited in severe cases. It is recommended to visit a qualified hospital promptly and follow medical advice for appropriate management.

　　Laser treatment works by applying laser energy of different wavelengths onto the skin, stimulating collagen regeneration and promoting skin repair, thus filling in depressed scars. For stable scars in adults, laser therapy can effectively improve their appearance. Laser treatment is generally suitable when the area of the atrophic scar is moderate.

　　However, if the scar has existed for a long time, with serious damage to the basal layer cells beneath it, or if the scar area is excessively large or deeply embedded in the skin, laser treatment alone may not adequately flatten the scar, and a combination of other therapeutic approaches may be necessary. After treatment, the local skin requires some time for healing and regeneration, during which proper sun protection and moisturization should be maintained.

　　In daily life, it is important to maintain a light diet, ensure balanced nutrient intake, and get adequate rest to support overall recovery.
