The sun does not help oily skin. While sun exposure may seem to dry out pimples, it actually increases melanin production and thickens the epidermis, which can clog pores and lead to more oil production.
It's important to use sunscreen even if you have oily skin. Many sunscreens are formulated specifically for oily skin and won't clog pores. These sunscreens help prevent sun damage, which can lead to wrinkles, age spots, and even skin cancer.
It's important to consult with a dermatologist if you have concerns about your oily skin and sun exposure.
