A fire boil is a folliculitis. After the folliculitis subsides, scars may form on the skin. There are many ways to get rid of folliculitis scars, including conservative treatment, laser treatment, liquid nitrogen freezing treatment and so on. 1. Conservative treatment: If the scars are shallow, you can apply vitamin E and other medications to lighten the scars. 2. Laser treatment: Laser can turn scar tissue from particles into powder, which will eventually be absorbed by the cells and removed, so as to achieve the purpose of removing scars, lightening pigmentation spots, and restoring the luster and elasticity of the skin. 3. Liquid Nitrogen Cryotherapy: Using the low temperature produced by liquid nitrogen, the scar tissue will be necrotic to achieve the purpose of treatment. Scars formed after the healing of fire boils are usually very small and it is not recommended to use more damaging treatments, such as radiotherapy, surgery and so on. Patients should follow the doctor’s instructions for treatment, do not blindly treat themselves to avoid causing adverse reactions.
