This problem is called acne which is common among many people. It is caused by clogging of hair follicles with oil and dead skin cells. At times, hormonal changes or genetics can also contribute to its occurrence. To clear up your skin, you can wash it gently using your hands only. Avoid scrubbing too hard as this could worsen the condition. Select non-comedogenic moisturizers that won’t block pores while keeping the face hydrated throughout the day. Alternatively, consult with a dermatologist for further advice on how best to treat this.
