Your new regimen is a very safe and effective approach for melasma. The primary difference is that your new morning cream contains skin-lightening ingredients like kojic acid and arbutin paired with UV-protective filters to shield your skin during the day. Your night cream features concentrated depigmenting agents and exfoliants to target pigmentation while your skin repairs itself overnight. This dual morning-and-night routine is a standard, highly beneficial dermatological strategy. It maximizes pigment clearance while keeping your skin healthy. Please ensure you also apply a broad-spectrum sunscreen daily, as sun protection is vital for curing melasma.
