Ultraviolet screening agents derived from algal natural products that protect the marine microbes from the sun can boost the sun protection factor of skin creams used by sunbathers.
When venturing out in the sun unfortunately, sun protection is never as simple as the application of cream to one’s skin. Indeed, there are several expert organisations that suggest any sun exposure is a risk factor for skin cancer and that dietary intake of vitamin D trumps the production of that essential substance in the skin under the action of ultraviolet light from the sun.
Sunscreens commonly contain substances designed to minimize the solar light transmission in the ultraviolet A (315 to 400 nm) and B (280 to 315 nm) regions. These compounds can delay the onset of solar erythaema, more familiar to us as sunburn. However, they have low photostability and ultimately do not protect the underlying biomolecules, and in particular, DNA, from ultraviolet photochemical damage. Moreover, there are safety concerns about many of these compounds, such as their ability to traverse the skin and enter the body. Many are known as endocrine disrupting chemicals.
The ideal sunscreen should block UVB and UVA radiation while being safe and stable, have now developed an entirely new family of UVA and UVB filtering compounds based on natural sunscreen substances found in algae and cyanobacteria. These compounds are highly stable and enhance the effectiveness of commercially available sunscreens.
HYDRA PROTECT – Natural product
The natural sunscreen molecules detecting by a different type of screening are called microsporine-like amino acids (MAAs) and are widespread in the microbial world, most prominently in marine red, blue and green algae plus cyanobacteria. MAAs are small molecules derived from amino acids, thermally stable, and they absorb light in the ultraviolet region, protecting the microbial DNA from radiation damage. These compounds are natural sunscreens.
The algal sunscreen are highly effective at filtering the pertinent UV range. In addition they are photostable, much more than, for example, oxybenzene which is a widely used sunscreen in commercial formulations. These compounds do not react chemically and dissipate radiation thermally. When added alongside commercial sun protection agents, these natural sunscreens boosted the sun protection factor (SPF) by a factor of more than two.
Sunscreen is key to protecting the skin from carcinogenic UV radiation. However, some synthetic sunscreen components can accumulate in aquatic environments and potentially cause harm by acting as hormone disruptors. One alternative to these ingredients is the biodegradable sunscreen compound shinorine, a UV-absorbing substance produced naturally by cyanobacteria and marine algae.
Hydraprotect clear zinc oxide is a specialised zinc oxide powder with high transparency and low whiteness and the safety and efficacy profile of a non-nano zinc oxide. It is made of nanoparticles that are strongly bonded together to form non-nano porous aggregate clusters.
Clear zinc oxide is safe for use in our sunscreen creams. It is listed as a safe and acceptable UV filter in the US and all major international markets, it meets stringent standards for ingredient safety and efficacy, and is acceptable for use in our
HYDRAPROTECT contains Vitamin E Oil to protect against & heal sunburn. When applied externally, Vitamin E oil acts as a natural sunblock and can actually protect you from harmful UV rays!
Hydraprotect with Vitamin E provides a barrier against solar radiation and protects the skin against sun damage. Two compounds work together to block UVA, UVB and UVC radiation.
- A physical sunscreen, which actually prevents the sun’s rays from penetrating the skin’s layers
- It’s the most stable and non toxic protection from solar radiation available anywhere
- Minimises free radical damage.
- Protects from UVA (ageing)
- UVB (burning)
- UVC which causes (cancer)
