See first you should know the reason for acne, why do they erupt? There are several reasons for it:
1. Due to hormonal imbalance: During adolescence there remains fluctuation in level of body hormones which lead to occurance of acne.
2. Presence of toxic substance in body: If you are not hydrated then rate of metabolism will slow down. So, drink plenty of water for flushing out toxic substances from body.
3. Clogging of dirt in the open pores: Try to wash your face with water and don't apply soap or face wash every time. Dust and dirt get sticked to face when you go out. If you don't keep your face clean then it will turn into boil.

Don't go for much cosmetics if your problem is severe. Introduce fruits and raw vegetables in your food and avoid oily and fatty food. The brands you mentioned are very good. If they are not suiting you go for natural products. Let your skin breath. If your problem is very severe then consult a doctor.
