Before Treatment: It’s essential to avoid sun exposure for at least one month before your Lumecca IPL treatment to ensure the safety and effectiveness of the procedure. Sun exposure can increase the risk of side effects, such as hyperpigmentation or burns, by making the skin more sensitive to light-based treatments. Additionally, tanning—whether natural or artificial—can affect the accuracy of the Lumecca, potentially diminishing the treatment’s efficacy. Protecting your skin by wearing sunscreen, covering exposed areas, and avoiding peak sunlight hours will help you achieve the best possible results from your Lumecca session.
