The health of a teenager’s skin is related to his or her degree of self-efficacy. Recent research has shown that young people with low self-efficacy have more skin problems than people with high self-efficacy.
Many people feel their skin to be itchy. But a study of more than 2,500 teenagers (aged 17 to 19 years) by the University of Oslo in Norway demonstrates that the incidence of itchiness is double among people with little confidence compared to people who are confident in what they are and do. Previous research had already shown that high self-efficacy may improve the immune system. Future studies will analyse whether therapies to recover self-efficacy can be useful in treating skin problems.
Eating fruits and vegetables is not just healthy. It also makes us more attractive by changing the colour of our skin. Six weeks of small changes to the diet are enough to produce positive effects.
A reddish-yellowish skin tone is associated with good health and is attractive to the opposite sex. The curious thing is that this also happens with species other than humans. A study by the University of St Andrews in Scotland shows that our skin acquires a reddish-yellowish tone from the carotenoids contained in fruit and vegetables, which, when consumed daily, improve peripheral circulation. In just six weeks, three daily servings of fruit or vegetables will make us sexier. Although the study was done with Caucasians, scientists believe the effect would also be noticeable in dark skin.
Acne is not dangerous, but it affects three quarters of the population worldwide, most especially individuals between 11 and 30 years of age, for whom it is a serious aesthetic problem. Current treatments are of limited effectiveness. But soon we may have more effective solutions.
Acne is an inflammatory disorder which originates in the overproduction of sebum (oil) by the sebaceous glands of the skin. The sebum blocks the hair follicles, which eventually become infected. The cause of this infection is the bacterium Propionibacterium acnes. Read More
Eye colour could indicate whether a person has a high or low risk of certain skin diseases. People with blue eyes are less likely to suffer from vitiligo, whereas people with brown eyes develop fewer melanomas.
Vitiligo is an autoimmune disease of the skin that causes pigment loss and light spots on skin and hair, while melanoma is the most dangerous of the skin cancers. Nature Genetics has published a study on 3,000 people with vitiligo that identifies 13 new genes associated with this disease. The statistical study shows that people with light-coloured eyes represent half of all vitiligo patients. The authors also conclude that people with dark eyes should therefore have fewer melanomas.
