Sensitive skin is experienced by millions of people as terse, reddened and flaky skin. The cause may be hereditary or psychosomatic or may be a reaction to external factors (cold, dryness and certain products). Sensitive skin can be treated, but it requires patience.

But how do we distinguish it from a skin that is temporarily reactive or from allergic skin? Read More
Medicine currently classifies human skin in six phototype groups (I to VI), based on sensitivity to the sun and covering people as different as platinum blondes and redheads to people with dark brown or black skin. It is important to know our skin type to care for it properly.

The study pointed to the high paraben levels in tissue samples from 18 breast tumours, indicating the possible influence on oestrogen activity of parabens, chemicals used as preservatives in the food, pharmaceuticals and cosmetics industries.
