The severity of acne dictates the choice of treatment. 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 damage your skin. Without examination of the skin condition and knowing the extent of involvement.. along with this more information on ongoing medication or history of previous/current skin/systemic illness it is not possible to comment on the treatment that would suit you best. You should send me images through private online consult for a better assessment of the problem and approaching it accordingly. Hope this is helpful.
