For several years diamond-dust creams have been sold as an outrageously expensive treatment used by celebrities to ensure they walk the red carpet with a fabulous complexion. Now, Asian scientists say they have managed to produce diamonds inexpensively in their laboratory — making this luxury skin care fad potentially more affordable.
The labels of creams containing diamond dust promise a smoother, younger skin from the first application, claiming that this gem has exfoliating properties that stimulate collagen production and help conceal wrinkles and blemishes. Marketing makes these texts not very different from those for other creams based on less exclusive ingredients. What is different, however, is the price of these exclusive creams, clearly aimed at the pockets of those who can afford the luxury. Read More
It may take a few hours for you to realise that you got sunburned while sunbathing. Similarly, the mutations that ultraviolet (UV) radiation can cause in DNA and that lead to the dreaded skin cancer continue for several hours after you’ve left the beach or the mountains and the sun has gone down.
Researchers at Yale University – led by Douglas E. Brash, a professor of radiology and dermatology – have published a study in Science that demonstrates that melanin, the pigment that darkens the skin to protect it from harm inflicted by UV rays, also has its downside. Certain components of this pigment are involved in the onset of DNA lesions that can cause the mutations responsible for melanoma – which continue for up to four hours after sun exposure has ended.

Humans, without being aware of it, have an internal biological clock that controls many of their bodily functions. The skin also has these circadian rhythms and organizes its activities according to the hours of the day and the night to be more effective. This way we can know when is the optimum moment to apply a cosmetic product on the skin.
A healthily functioning human body relies on internal biological rhythms and patterns. These circadian rhythms are controlled by an "internal clock", located in the brain, that modulates the metabolism of organs and tissues 24 hours a day. The science that studies these processes is called chronobiology. Scientific studies have demonstrated how our skin cells are governed by circadian rhythms that directly affect cell regeneration in the epidermis. Read More
Cosmetic or plastic surgery is no trivial matter. And not just because a person may become unrecognizable or lose something of their character, as has recently happened with celebrities. Misinformation and the tendency to make light of cosmetic surgery lead us to overlook the fact that it is still surgery, with all the associated risks. An Australian initiative recommends a mandatory cooling-off period of at least a week.
The Medical Board of Australia, which regulates medical practice in this country, wishes to remedy the current situation with its publication of a guide that recommends a cooling-off period before any operation. The aim is for the patient to consider all aspects of their decision to undergo a surgical procedure for purely cosmetic reasons. Caution is crucial, especially in light of complaints and cases of malpractice by unqualified personnel operating in ill-equipped clinics. Read More
