The hard bumps left after acne are considered to be hyperplastic scars, which usually need to be treated with local medication, local hormone sealing treatment or fractional laser treatment.
1. Local medication: If the current scar hyperplasia is not very serious, you can apply medication that can soften the scars, such as Mucopolysaccharides Polysulfate Ointment, Cumexin Cream, etc., but generally can not completely remove the bumps.
2. Local hormone closure treatment: If the raised hard lumps are more obvious, you can locally inject a small dose of glucocorticosteroid drugs and carry out closure treatment.
3. Fractional laser treatment: for hyperplastic scars, the current better treatment is fractional laser, through the principle of peeling fractional laser, the hyperplastic scars will be smoothed, thinned, so as to play a role in the treatment.
After acne leaves hard bumps should pay attention to the local care, avoid irritation, which can easily lead to bigger bumps.
