A recently published survey on medical oral photoprotection prescription in Asia revealed the top 3 reasons for such practice among Dermatologists and Medical Aesthetic practitioners:
☑ 46% Hyperpigmentation
☑ 30% Healthy sun exposure
☑ 14% Aging
Polypodium leucotomos extract (Fernblock®) from the Fern plant is a very well-studied photoprotectant - it can be taken orally or applied topically to help prevent skin cancers and photo-aging.
In its oral form, such photoprotecting supplements act as an antioxidant against free radicals caused by UV radiation. Studies have shown that they can reduce redness, sunburn and DNA damage.
