    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

    When smelling bad is not a matter of hygiene

    An offensive body odour may not be the result of a lack of hygiene. Bromhidrosis is a disorder affecting both men and women and usually associated with secretions by the apocrine sweat glands located in the armpits, pubis, perineum and navel, behind the ears and in the folds under the breast. It is a chronic but treatable disorder.

     

    Persons affected by bromhidrosis do not perspire more; rather, their apocrine glands produce sweat containing ceramides that are different to those of the rest of the population. When broken down by the skin’s bacteria, a strong odour is the result. This odour, which is often described as pungent, musty or sour, cannot be dissumulated. The condition is believed to be genetic in origin, but may also be caused by a metabolic disorder such as diabetes, by thyroid or adrenal gland alterations or by certain drugs. In addition, certain foods, such as onions, garlic and spices, and also tobacco use and alcohol consumption, can aggravate the condition. Read More

    Seven reflections before deciding on laser hair removal

    21 Aug Seven reflections before deciding on laser hair removal

    Skin Care Guide

    The use of laser as a hair removal technique has become very popular in recent years. What are the risks for the skin? For which parts of the body is it not recommended? How should you choose a centre? Before making a decision, you need to be well informed and to consider the possible implications.

     

    How is the hair removed? Laser is a technique, used since about ten years ago, that destroys the hair root using beams of light of a specific wavelength and intensity. Melanin, which is responsible for hair colour, absorbs the light’s energy and converts it into heat that destroys the root without damaging the surrounding areas (selective photothermolysis).

     

    What kind of laser? Different types of laser, which are effective in different ways depending on the hair type, can be combined during treatment. For example, alexandrite laser is good for removing medium to thick hair, while diode laser is more appropriate for male hair. Other widely used lasers are Nd:YAG and intense pulsed light (IPL).

    Can stretch marks be removed?

    31 Jul Can stretch marks be removed?

    The term “stria” refers to a line, groove or ridge in a surface. Striae now refer to the marks that appear in the skin when it stretches and tears. Appearing in adolescence, as a consequence of pregnancy and when weight is gained or lost, they are difficult to hide. All kinds of creams and other more drastic solutions to combat them are offered in the market. But is it really possible to remove them?

     

    When stretch marks first appear, they are reddish or violet coloured but they eventually become whiteish to the point where they seem to be simple scratches. Their name directly reflects their origin in an overstretching of the dermis due to changes in the body. However, they are caused in different ways. In the early twentieth century they were attributed to infections such as tuberculosis or typhoid. Later they were also associated with malnutrition and toxic states. Most contemporary theories link them to hormones, specifically glucocorticoids (cortisol, basically), which affect the formation of collagen and elastin, both necessary to keep the skin elastic. Some experts, in the absence of other evidence, blame the genes. Read More
