Plastic microparticles used in many cosmetic products end up in the seas and oceans, posing a major environmental problem. Fossilized coral powder, to date used mainly in nutritional products, could solve this problem, because its properties mean it is as beneficial for the skin as it is harmless to the ecosystem.
It contains calcium, magnesium and traces of over 70 minerals, so it is primarily sold as a nutritional supplement. However, some researchers are beginning to consider it as a possible sustainable ingredient in personal hygiene formulations. Fossilized coral powder is a novel material with useful chemical and physical properties that can help maintain the barrier function of the skin and improve its ability to regenerate. Furthermore, it does not harm the environment and it respects the fragility of coral reefs, since it is extracted from onshore deposits that lay under the sea millions of years ago. Read More
Day or night, mosquitoes are very annoying when they attack our skin. In some parts of the world they also transmit serious diseases. Popular lore and scientists describe several ways to avoid their bites. But mosquitoes are hugely adaptive...
Apart from a pepper derivative called icaridin, N,N-Diethyl-meta-toluamide, known as DEET, is one of the most studied and widely used insect and arachnid repellents. However, according to a recent study published in the Plos One journal, DEET is losing its effectiveness against mosquitoes and the reason is that exposure to this chemical changes their olfactory system. In other words, the mosquitoes get used to the smell and carry on as regardless. So what alternatives are there? Read More
Sunburn is dangerous. It may increase the risk of skin cancer, even though we may have been burned – as children – before we were aware of the consequences. We have been warned time and again, but we still see skins red as tomatoes from the sun.
That’s why some organizations continue to emphasize informing the consumer. This Cancer Research (UK) video explains what happens to cells when the sun damages them and the difference with other burns caused by hot objects. The other burns heal, but burns from the sun can have dramatic consequences many years later. Contact burns merely destroy some skin cells, nothing more. Sunburn also destroys cells, but it also alters the DNA of surviving cells and this can lead to the development of cancer. A simple but enlightening reason not to forget to protect yourself from the sun. Read More
It is known for its reparative potential and sold as an anti-wrinkle agent, but according to a new study published in Dermatology and Therapy, resveratrol also helps cure the unsightly pimples that appear on the skin. Especially when combined with benzoyl peroxide, an antimicrobial agent widely used in anti-acne creams.
The alliance of opposites: Resveratrol is an anti-oxidant and benzoyl peroxide is an oxidizer. But together they seem to be effective in fighting acne. This is the conclusion of research by scientists in the dermatology division of the David Geffen School of Medicine at the University of California (UCLA), who claim that resveratrol enhances the bactericidal effect of benzoyl peroxide and inhibits growth of the Propionibacterium acnes bacterium responsible for acne over a longer period (over 24 hours). Additionally, the formula is not harmful to the skin. Read More
