Erythromycin ointment to get rid of spots is not reliable. First of all, the formation of spots is mainly due to the inflammation of the skin, under the stimulation of inflammatory factors, the function of melanocytes is enhanced, so that the synthesis of melanin particles increased, so that the skin color deepens, that is, the deepening of the pigmentation of the post-inflammatory period. The main ingredient of erythromycin ointment is erythromycin, a macrolide antibiotic, mainly for skin bacterial infections, especially gram-positive bacterial infections. It has an antibacterial effect in the early stages of inflammation and is effective in treating skin infections such as folliculitis, boils, pimples and abscesses. When the bacteria are controlled, the inhibitory effect of erythromycin on inflammatory factors disappears, and it can not play a role in removing the spots, for the facial spots or other parts of the skin of the body is not able to remove the spots, there is no obvious therapeutic effect. For skin discoloration, targeted treatment should be carried out according to the specific situation, while attention should be paid to diet and living habits, and direct sunlight should be avoided. For chloasma, laser treatment or electro-ionization and hydro-photo-needle treatment can be carried out; for white spots, medication or phototherapy can be used. Please go to regular hospitals for treatment under the guidance of doctors.
