Arencia Vitamin C Booster Shot is a concentrated brightening serum designed to improve the look of dull, uneven, and tired-looking skin while supporting a fresh healthy glow. The formula is powered by a Dual Vitamin C Complex, including 3-O-Ethyl Ascorbic Acid 50,000ppm and pure vitamin C, to help visibly even skin tone, enhance radiance, and refine rough-looking texture. It is boosted with niacinamide to support smoother-looking clarity, glutathione and vitamin E to provide antioxidant care against environmental stressors, and panthenol with allantoin to help soothe, comfort, and maintain hydration. The lightweight texture absorbs quickly without a heavy feel, making it suitable for targeted use on dull areas or full-face brightening care. This booster shot is ideal for skin that looks lacklustre, uneven, or fatigued and can be used in daytime routines every other day with sunscreen or at night before moisturiser. For best tolerance, new vitamin C users should start slowly, patch test before use, and avoid combining it in the same routine with retinoids, strong exfoliating acids, or other intense active products.
