The sun can increase your sebum production, causing your skin to look oily on occasion. When the oil combines with dirt and sweat, pores get clogged. Be meticulous about your cleansing routine, morning and night. Use non-soap based gentle cleanser that will deep cleanse without drying out the skin. A good cleansing mix for dry/normal skin can be made with honey, lemon and rosewater. For oily skin, some neem or narangi. Look for a toner without alcohol and do not forget to wear your sunscreen daily, according to your skin type. Here is a list of sun protection products that will protect you from sun tan, clogged pores and uneven skin tone.
