Usually you can't cover it with bangs. The forehead belongs to the oil-prone area. Covering your forehead with bangs may make your skin airtight for a long time, and the time for eyebrows to recover will also be extended. Moreover, covering the forehead with bangs may make it easier for the forehead to sweat, which may easily lead to the accumulation of oil and clog pores and affect the recovery of the skin. The problem of hanging needle and thread can be removed by laser surgery. Laser can stimulate the collagen layer of the face and produce new collagen, thus filling the depressed and wrinkled skin and stimulating the regeneration and reconstruction of self-repairing tissue. Laser can remove fine lines on the face, and it is also effective for pigmentation and erythema, which can improve and beautify the skin. The operation can be carried out without anesthesia, and the treatment time is about 30 minutes, and no scar will be produced. Any medical beauty project has a corresponding recovery period. Try not to use skin care products containing chemical ingredients during the recovery period. If you need to use it, you should communicate with the medical staff so as not to affect the medical beauty effect. The choice of different medical beauty projects should be carried out in strict accordance with the doctor's advice. Medical beauty is risky, so the choice should be cautious.
