Finally, the team noted that as the antioxidant mix does not generally absorb rays within the UVA/UVB spectrum, any protective effects of the treatment are not due to sunscreen-like effects.
“These studies document that substantial photoprotection can be achieved by an antioxidant solution containing vitamin C, ferulic acid and phloretin,” concluded the authors.
Furthermore, as the antioxidants do not act as a sunscreen they are unlikely to interfere with the application of more traditional sunscreens. As sunscreen application to the skin’s surface is rarely uniform, the researchers believe treatment with antioxidants could significantly boost protection. Antioxidants protect from inside the skin, and as they stimulate the cell’s own defence mechanism they remain active for several days.
