photodamage

Photoaging Dermatology The structural and functional deterioration of sun-exposed skin, resulting in wrinkling, roughness, altered texture, discoloration, acral lentigines, mottled hyperpigmentation, ↓ epidermal thickness, basophilic degeneration of dermis, ↓ collagen, ↓ dermal vessels, epithelial atypia, dysplasia Management Photoaging is largely reversed by tretinoin

Researchers from the cosmetics industry have debated for years whether UVA is worse than UVB for causing photodamage, which leads to the early onset of wrinkles and increased tissue fragility.
Further, the investigators formulated bakuchiol into a skin care product and tested it clinically, with twice-daily applications over 12 weeks yielding significant amelioration in lines and wrinkles, pigmentation, elasticity, and firmness, as well as overall diminished photodamage without provoking redness.
According to Josh Ghaim, PhD, chief technology officer, Johnson & Johnson Family of Consumer Companies, J&J shared science in skin health areas important to the professional community, including hydration, photodamage, low-level light therapy, microbiome and hair loss.
"While injectable hyaluronic acid fillers are the current standard for lip rejuvenation, it fails to treat deep wrinkles and photodamage," Dr.
Plus, it fights photodamage, which causes premature aging."--Dr.
'It's easily the one that has gotten the best response from the biologists, even more so than the PALM technique that got me the Nobel, because it offers super high speed, it's really good, near isotropic resolution and extremely low photodamage. But to really take advantage of that in a multicellular context, you need the adaptive optics.'
SPF 15 blocks 93 percent of UVB rays (which cause sunburns, skin cancer, and photodamage).
Call this "skincare in a bottle" for its many benefits: multi-defense protection from harmful rays, 12-hr time-release antioxidant complex guards against photodamage, DNA protection and repair, minimizes inflammation, restores hydration, smoothens skin.
Papulopustular rosacea: prevalence and relationship to photodamage. J Am Acad Dermatol 2010; 63: 33-9.
Further, the development of cutaneous tumors in response to carcinogens in vitamin D receptor deficient mice has led to the hypothesis that consistently raised serum vitamin D levels in response to chronic sun exposure protects against melanoma Besides this, adequate serum vitamin D levels may decrease the incidence of solid organ tumors like those of stomach, liver, colorectum, gall bladder, pancreas, lung, breast, prostate, bladder and kidney, although the risk of non-melanoma cutaneous tumors is maintained due to the similar wavelengths required for vitamin D production and cutaneous photodamage. Studies have also revealed a correlation between serum vitamin D levels and cancer severity, with higher vitamin D levels observed in stage I melanoma vs stage IV tumor.
