Guava Vitamin C Dark Spot Brightening Treatment Serum

A lightweight serum that targets hyperpigmentation and dullness using a stable blend of five vitamin C derivatives alongside tranexamic and ferulic acids. It's designed to brighten existing dark spots while protecting against the environmental stressors that cause new ones. Most vitamin C serums rely on a single active, but this one uses five different forms to ensure better stability and less irritation. The lightweight texture avoids the stickiness often found in brightening treatments, making it easy to layer under moisturizer or SPF.
