Can a Supplement Like Heliocare Protect Your Skin from the Sun?

Before I start I would like to make it clear that taking an oral antioxidant doesn't replace applying sunscreen daily. It's supposed to supplement it, so continue to apply your sunscreen every day.
Heliocare 360º capsule formula is recommended during the months of highest intensity or longest sun exposure and especially in photo-ageing conditions, hyperpigmentation, sun sensitivity and for people with a high risk of sun damage.
-Heliocare is a daily supplement that helps your body fight off free radicals for fewer sunburns, less long-term damage from environmental stressors, and younger-looking skin.
-Made from A blend of powerful antioxidants and Fernblock PLE Technology, which uses Polypodium leucotomos fern.
-Reducing free radicals, slowing down collagen degradation, preventing skin darkening and repairing the function of the skin; these are some of the many benefits Fernblock delivers.
-Recommended to take 1 capsule a day during high-level sun exposure.
Customer review:
"I was recommended taking the Heliocare supplements once a day the month before my summer holiday and also during and what a difference!
Very little reaction, minimal rash and no itching, now I take them every holiday! "
I have a sensitivity to the sun called Polymorphous light eruption (PLE) that causes a bumpy, itchy rash on my hands, feet and chest when I have been exposed to too much sun. Sunscreen alone does not prevent it."
