Detailed answer

To apply sunscreen over blackheads, first cleanse your face thoroughly to remove any dirt or oil. Then, take a small amount of sunscreen and dot it over your blackheads using clean fingers or a soft brush. Gently spread the sunscreen over the blackheads, being careful not to rub or irritate them. Make sure to cover the entire area with a thin, even layer of sunscreen. Allow the sunscreen to dry before applying any makeup or other skincare products. Remember to reapply sunscreen every two hours or as directed on the packaging to ensure adequate sun protection.
