Hi..
For pimples and acne, best permanent solution other than eating habits is applying lacto calamine.
At first, application may not seem good to you like some dryness and stuff, you will not feel good..but yes after applying it on regular basis you will get used to and once after using continously for 6 months, there is no acne ever other than 1-2 pimples that to sometimes ( occasionally)..
Right now in winter season, you can use laco calamine iwth moistriser or can avoid it if extra dryness occurs, else start with this in summers and apply for 6 months and see the result.
