Update on Photoprotection

Photostability enhancement by encapsulation of α-tocopherol into lipid-based nanoparticles loaded with a UV filter

“…Sunscreens on the market are based on UV filters that absorb, scatter or reflect the UVB (290-320 nm) and/or UVA (320-400 nm) rays [15]. Recently, it was found that the UVA rays are even more dangerous than the UVB rays.…”

Integrative approach in prevention and therapy of basal cellular carcinoma by association of three actives loaded into lipid nanocarriers

“…Even though, initially sunscreen formulations were developed to prevent sunburns, today they are medical advised for skin cancer prevention by limiting at skin level the deoxyribonucleic acid (DNA) damage produced by UV radiation, directly or indirectly through reactive oxygen species (ROS) [10,11]. Due to the increased UV radiation exposure and the fact that the photoprotection measures are disregarded by individuals, like regular topical application of sunscreen, use of protective clothing and avoidance of sun exposure during the hours of peak UV radiation [12], over the last three decades the number of skin cancer has continuously increased [13].…”

Intake of Oral Photoprotectors by Postmen in Porto Alegre

“…Oral photoprotectors are sources of endogenous protection obtained through feeding or supplementation. These compounds act in the development of the protective barrier of the skin against solar radiation, in the antioxidant action protecting biomolecules, in the induction of cellular repair systems, and in the anti-inflammatory action [8][9][10] . The nutritional contribution has a complementary role to the other photoprotective measures 8,11 .…”
