Brightening Duo Set: Ascorbyl Glucoside 12% & Retinal 0.2%

Day and night each get their own step in this pairing. Ascorbyl Glucoside Solution 12% handles the daylight hours — a water-light vitamin C derivative that helps skin look brighter and more even without the sting stronger acids can bring. After dark, Retinal 0.2% Emulsion takes over, using stabilised retinaldehyde in a cushiony emulsion texture to address the look of lines and patchy tone. Keep the two on separate schedules rather than layering them, always finishing with moisturiser. Introduce the retinal gradually, a couple of nights per week at first.
