Hello, Pimple, acne commonly occur due to hormonal imbalance, poor hygiene, dandruff that keeps falling on the face, oily skin type, taking too much of non vegetarian diet, exposure to sunlight, etc. You are suggested to keep your scalp clean, shampoo your hair with Selsun shampoo or any anti dandruff shampoo every alternate days. Take bath everyday. Keep your hands clean, do not keep touching your face. Restrict the use of make up or chemical cosmetics. Take vegetarian diet with plenty of veggies and fruits, take yogurts, dry fruits and milk. Avoid being constipated. Take laxatives at bed time. Constipation triggers acne and pimples. Get clinically examined by a dermatologist to assess your skin type and get treated accordingly. There are many types of laser treatment. You can also treat your skin naturally by applying sandalwood with turmeric and lemon face packs twice daily. Turmeric is an antibiotic it will clear pimples. To remove dark spots you can use any skin lightening cream that suits your skin type. Take care. Hope I have answered your question. Let me know if I can assist you further.
