Prevent, protect, correct. Antioxidant serums defend skin from the free-radical damage behind visible ageing, broad spectrum sunscreens block what antioxidants cannot, and targeted correctives work on the lines, laxity and discolouration already there. The formulas are deliberately single-minded: high concentrations, proven actives, no padding.

The antioxidant serums follow the Duke parameters: pure L-ascorbic acid at 10 to 20 percent, at a pH below 3.5, in stable combination with ferulic acid. A few drops each morning under sunscreen is the core ritual; correctives layer in at night. These are concentrated formulas, so introduce one at a time and let your skin tell you the pace.
