The treatment of acne differs according to the grade of involvement. In the early grades of acne even the cream might suffice however in moderate to higher grades tablets also need to be taken. The treatment has to be continued for a few months otherwise the pimples would tend to return easily. Kindly do not self medicate without professional advice as that could further damages your skin. The marks and pores left behind after the pimples heal can also be treated. Get an online consult or meet a dermatologist directly for a proper evaluation of the condition. Hope this was helpful.
