Synopsis Solar radiation, especially ultraviolet A (UVA) and ultraviolet B (UVB), can cause damage to the human body, and exposure to the radiation may vary according to the geographical location, time of year and other factors. The effects of UVA and UVB radiation on organisms range from erythema formation, through tanning and reduced synthesis of macromolecules such as collagen and elastin, to carcinogenic DNA mutations. Some studies suggest that, in addition to the radiation emitted by the sun, artificial sources of radiation, such as commercial lamps, can also generate small amounts of UVA and UVB radiation. Depending on the source intensity and on the distance from the source, this radiation can be harmful to photosensitive individuals. In healthy subjects, the evidence on the danger of this radiation is still far from conclusive.

“…The interaction between different wavelength bands, such as visible light, UV radiation and infrared plays an important role in the development of these effects. 15 Infrared radiation (IR) can transmit energy as heat, raising the temperature of the skin. Human skin exposed directly to IR can have its temperature raised to over 40 °C due to conversion of IR into heat.…”

Ultraviolet radiation can damage the DNA, cause immunosuppression, chemical and histological alterations in the epidermis, early photoaging, cataracts and carcinogenesis, among others. Photoprotection prevents these and other harmful effects of ultraviolet radiation. Sunscreens, protective clothing, proper accessories and safe sun exposure are essential photoprotection tools. The main forms of photoprotection are presented and discussed in this article, including sunscreens containing organic and inorganic filters, the assessment of their efficacy and current developments on the topic. Keywords: Protection; Radiation protection; Solar radiation; Sunscreening agents; Ultraviolet filters Resumo: A radiação ultravioleta pode provocar danos ao DNA, imunossupressão, alterações químicas e histológicas na epiderme, envelhecimento precoce, cataratas e carcinogênese, dentre outras deteriorações. A fotoproteção previne estes e outros efeitos danosos da radiação ultravioleta. Protetores solares, vestimentas, acessórios adequados e exposição segura ao sol são ferramentas essenciais da fotoproteção. Neste artigo, são apresentadas e discutidas as principais formas de fotoproteção, incluindo os protetores solares com filtros inorgânicos e orgânicos, a avaliação da eficácia dos mesmos e atualizações envolvendo o tema.

Just like UV radiation, heat increases collagen degradation and accumulation of abnormal elastin fiber and this is termed thermal skin aging. Dunaliella salina (DS), a green alga, is known for its beta-carotene accumulation, having various applications in the health and nutritional products. However, the effects of DS on heat-induced skin aging remain unexplored. In this study, we performed anti-thermal aging tests of the ethanol extract of DS (DSE). We measured the cellular levels of type I procollagen and MMP-1 using ELISA in human dermal fibroblast cells after heat shock. DSE reduced the expression of MMP-1 protein and increased the expression of type I procollagen. In addition, DSE upregulated the mRNA expression of HSP47 reduced by heat shock, which is involved in collagen synthesis. Also, DSE reduced the expression of inflammation mediator (TGF-β, IL-12, etc). We demonstrate that DSE regulates the heat-induced solar elastosis through the regulation of tropoelastin and fibrillin-1, two major proteins of elastic fibers, and MMP-12 expression. These results suggest that DSE may be effective for preventing thermally induced skin aging.
