Pimples despise cleanliness and just pack up and flee if you wash the face and all affected parts regularly. Your best zit-zapping plan of attack is to wash with soap and warm water in the morning and at night, and rinse well with cool water before patting them dry with a clean towel. Take care that you wash thoroughly, especially in the areas where grease tends to accumulate-as in the crevices such as nasal folds. Ordinary soap is quite adequate, although mild non-greasy ones are the best. Keep the hair clean.
Greasy hair means greasy skin.
You could do better without it. Shampoo your scalp regularly and if you have dandruff, use a selenium sulphide or a similar anti-dandruff shampoo. Go for the natural look. Use as little make-up as possible. In case you must, use only non-greasy cosmetics.
