Daily application of a broad-spectrum sunscreen is crucial for preventing and managing hyperpigmentation. Choose SPF 30 for regular daily exposure or SPF 50 for prolonged or intense sun exposure (high UV index).
If using professional treatments or active ingredients such as retinoids, Vitamin C, or Hydroquinone, always opt for SPF 50 regardless of the season or hours of sun exposure. These treatments can make your skin more sensitive to UV rays, and insufficient protection may cause pigmentation to return, potentially even more pronounced. Reapply sunscreen every two hours when outdoors to maintain sufficient protection.
