Acne pimples are generally atrophic scars caused by severe acne, and can be eliminated by chemical peeling, phototherapy, injections, and other treatments. 1. Chemical peeling treatment: You can use chemical agents such as salicylic acid or fruit acid to act on the area with pimples, which can stimulate the epidermal tissues in the area and promote the proliferation of elastic fibers and dermal fibers, making the local tissues bulge. 2. Photoelectricity treatment: Fractional laser, YAG laser and other methods can be used to act on pimples to promote collagen remodeling in the area. Intense pulsed light can also be used to stimulate collagen regeneration in the acne pits through the action of light and heat to improve the acne pits. 3. Injection treatment: Hyaluronic acid can be injected into the pimple area to alleviate small skin depressions. 4. Other treatments: Micro-needling, subcutaneous detachment and dermabrasion can also be used to alleviate the symptoms. It is recommended that patients with acne pits go to the dermatology department in time, and standardize the treatment under the guidance of professional doctors, do not use drugs privately, so as not to cause danger.
