Pimples are very common in your age group, due to effect of hormones. With age they tend to come. We just need to make sure they don't get infected, which then leads to permanent dark spots. Wash your face as often as you can (Acnestar soap) to clear dust particles which block the gland ducts. Limit sugary foods n sweets. Use Deriva CMS gel at nights when new pimples come despite these measures. For grade 3 to grade 4 acne, you will need supervised treatment with next level medicines (oral retinoids and antibiotics).
