Hi Thank you for asking HCM I have gone through your query.Pimples are usual in puberty and youth due to over action of sex hormones.Excess eruption results from the style of diet like too much oily and fatty foods in diet and excess stress but in some it is genetic also.Take food which has more antioxidants like kale spinach broccoli carrots.Avoid junk foods excessive milk products and egg yolk.Wash you face twice daily with acne soap.Nicomide cream is helpful for acne when use at night.I also advise creams with combination of tretinoin hydroquinone and flucinolone to get rid off dark spots.But it should be used at night and avoid sunexposure to face.A good sunscreen should be used also.Hope this may help you. Let me know if you have any further query.
