Sunscreens protect the skin from UV rays and are essential for risk-free summer tans. But they also have a negative side. According to a recent study, the chemicals in sunscreens are toxic for marine organisms and can have serious consequences for the ecosystem.
The sunscreen that we wear when we dive into the sea after a spot of sunbathing is harmful to marine phytoplankton, according to a recently published article by researchers at the Mediterranean Institute for Advanced Studies and the Andalusian Institute for Marine Science (Spain). From analyses of water from a popular beach in Mallorca (Balearic Islands) during August, the scientists concluded that levels of hydrogen peroxide, a powerful oxidant, tripled at peak bathing times.

Acne, particularly common in teenagers, is one of the world’s most common skin disorders. Although it results in a wide range of lesions, acne, even if untreated, is often benign. However, sequelae in the form of scars may persist for life.
Acne is such a common problem that we often take it for granted as a normal physiological phenomenon. Some 85% of adolescents experience, to a greater or lesser degree, acne lesions of various types: comedones (blackheads and whiteheads), papules (pinheads), pustules (infected pimples) and nodules (larger, raised and often painful lesions).

We say that someone’s skin is atopic when it has a tendency to develop atopic dermatitis. It's that simple. Atopic dermatitis is the most common skin disease in children. It not only affects the quality of life of the child, but also of the family. Leaving aside correct diagnosis and treatment by a dermatologist, there is a great deal of controversy about other issues affecting these children, such as skincare, clothing, bathing, etc.
Atopic dermatitis (or atopic eczema) is a very common skin disease, which affects in the western world one out of three babies during the first years of life. The main symptom is itching. While there is no single known cause, clinical manifestations enable the paediatrician or dermatologist to make the correct diagnosis (there is a significant hereditary component). These children are at increased risk of developing asthma, urticaria and allergic rhinitis. The disease is not stable, but evolves in stages marked by flare-ups (typically occurring in winter) and by dormant periods. Read More
