Personally, I am not a small person. Meaning I eat a lot of junk food. I don't do anything to my face. I wash it with a face cloth in the shower and I use Glaxal Base Moisturizing lotion after. I don't touch my face a lot, and Ive been acne free for 2 months :)
Keep from touching your face a lot. the oils from hands can cause acne and at least wash your face with warm water everyday or I suggest using a face wash. Try a few different brands because different ones work on different people.
