Summer means hot sun, humid weather, beach parties, and excessive exposure to UV rays. These are the main reason why you need to up your skincare routine. With high heat, your skin produces more sebum, which increases oiliness on your face. This can cause the pores to get blocked, which in turn would lead to blackheads, whiteheads, and acne. Too much face time in the sun can also give way to burnt skin, rashes because of sensitivity, and itchy skin.
