Yes! However, the treatments could make your skin more sensitive to the sun, so regular use of sunscreen is VERY important. We recommend using a mineral broad-spectrum sunscreen daily. Musely offers The Day Cream that was formulated by our dermatologists to provide the best protection against the sun’s harmful UV rays. Best of all, The Day Cream is affordable and designed to work with all FaceRx medications in reducing hyperpigmentation! Additionally, reapplying sunscreen every 2 hours and taking other precautions, such as wearing a hat in direct sunlight, is highly recommended.
