iS Clinical GeneXC Serum
Why We Love This Product
The highest vitamin C concentration in the line at 20% L-Ascorbic Acid, built with iS Clinical's Extremozyme complex, superoxide dismutase, and a blend of fruit acids from lemon, orange and apple. Kakadu plum adds further vitamin C. It is a light fluid that absorbs quickly and does not pill under sunscreen. No other percentages are published by the brand.
For skin with visible sun history, uneven tone, or dullness that a lower-strength vitamin C has not shifted. Mornings only, on dry skin, before moisturizer and under SPF. Three to four drops. Skip your acid toner on the same morning, as the fruit acids are already in the bottle. Ten weeks before you judge it.
