TAP (Total Antioxidant Power) Technology uses PQQ and Ergothioneine to specifically neutralise intrinsic free radicals, the reactive oxygen species generated by the skin's own metabolic processes and natural ageing, as distinct from external environmental sources. Most antioxidant serums only address extrinsic free radicals. Addressing intrinsic ones too makes Alto relevant for both types of oxidative stress driving skin ageing.

Yes, THD Ascorbate (stabilised vitamin C) is one of its 19 antioxidants. The formula also includes 17 additional actives covering a much broader range of free radical types and environmental aggressors, including blue light, pollution and infrared that a standard vitamin C serum doesn't address. For anyone currently using a single-antioxidant vitamin C serum, this covers considerably more ground.

Yes. Paraben-free, fragrance-free, dye-free and dermatologist-tested. It contains Bisabolol for additional soothing and anti-inflammatory benefit, and is specifically noted as suitable for sensitive and rosacea-prone skin.
