Dr. C. Tuna Lumi Radiance Brightening Toner 125ml is a luminosity-enhancing facial toner designed to brighten, refine, and prep the skin immediately after cleansing for maximum absorption of subsequent brightening treatments. Infused with gentle exfoliating acids, vitamin C derivatives, and hydrating botanicals, this toner works to dissolve dull surface cells, minimize the appearance of pores, and deliver an initial layer of brightening actives that prime the skin for serums and creams. Its alcohol-free, pH-balanced formula ensures that the skin's natural barrier remains intact while tone-correcting ingredients begin working from the very first step of the routine. The refreshing, lightweight texture sweeps across the skin smoothly, leaving it feeling clean, hydrated, and visibly more radiant without any tightness, stinging, or irritation. This 125ml bottle serves as the essential foundation of the Lumi Radiance brightening system, setting the stage for cumulative results in clarity, evenness, and natural glow.
