Acne is somewhat related to the vigorous secretion of one's own sebaceous glands. During the treatment process, most people either treat improperly or frequently pick and squeeze their acne, which can lead to scars that are troublesome to treat if broken. If the scar proliferation is not too pronounced and relatively flat, one can visit a reputable hospital's dermatology department for fractional laser treatment. If the scar proliferation is more obvious and raised, medical interventions at a hospital may be necessary, typically involving two to three injections. This can generally soften, flatten, and shrink the scar slightly, but it is impossible to completely remove it. This condition is also somewhat related to individual constitution. During treatment, one should maintain proper dietary and lifestyle habits. During the acne treatment period, try not to pick, squeeze, or scratch the acne to prevent scars from forming.
