    Cold sores for life

    The fever blisters or cold sores that typically appear on the lips are manifestations of the herpes virus, which can also affect the skin elsewhere. Herpes is an extremely common viral infection and, although rarely serious, it causes major discomfort and is also anti-aesthetic. Even more bothersome is the fact that cold sores usually recur over a lifetime.

     

    Herpes labialis is an infection caused by the herpes simplex virus, whose symptoms are observed mainly in the skin and the mucous membranes. It is usually acquired in childhood, so by adulthood most individuals have had contact with the virus. Cold sores on the lips are, in fact, just one of the manifestations (although the most common by far) of herpes simplex infection; the virus can also cause eye problems, affect the inside the mouth or the genitals and even cause more serious problems (meningitis).

    Why do we get goosebumps?

    5 Aug Why do we get goosebumps?

    The term transmits the accompanying sensation well. Alternatively called cutaneous horripilation or piloerection, this condition develops when we feel fear, cold or an emotion that affects us deeply. This is what we refer to as goosebumps. But why do they develop?

     

    Goosebumps are a manifestation of cold on the skin, a reflex inherited from our ancestors aimed at maintaining body temperature and also warning of danger. Goosebumps are triggered by adrenaline – a hormone produced by the adrenal glands – sending an alert message to the body. The hair reacts by bristling, except in the area of ​​the genitals. This reaction occurs because of the contraction of a muscle called the erector muscle (or arrectores pilorum), situated near the hair follicle – that is, near the roots of the hairs that cover the skin mantle. The pores close in response and the skin forms a small swelling around the hair follicle, resulting in what we call goosebumps — maybe because they remind us of the skin of plucked chickens.

    Exercising rejuvenates the skin

    Exercising is less expensive than wrinkle creams and is, judging by a recent study from McMaster University in Ontario (Canada), more effective. Exercising improves the appearance of the skin and slows down the signs of ageing, even in those who take it up late on in life.

     

    According to researchers at McMaster University, after the age of 40, men and women who do at least three hours per week of sport have smoother, healthier skin and a thicker dermis than the average for their age cohort. In other words, their skin resembles that of people aged 20 to 30 years old. Although it is still unclear what changes exercising brings about in the composition of the skin, these scientists think the anti-wrinkle effect may be due to the paracrine action of the muscle-produced myokine hormone, which induces changes in specific receptors in neighbouring cells.

    Which cellulite and how to treat it

    20 Jul Which cellulite and how to treat it

    Cellulite is an aesthetic problem of the skin that affects most women. Insistent advertising tries to take advantage of the complex women have about “orange-peel skin”, promising almost miraculous outcomes but often failing to deliver. But don’t be discouraged. While there is no 100% solution for eliminating cellulite, good diagnosis and proper selection and application of treatments can help reduce cellulite and improve your health.

     

    Nine out of ten women say they are concerned about cellulite, which is an abnormal fat accumulation that occurs in certain areas of the body (especially the thighs, hips, buttocks and stomach). However, over 30% admitted not doing everything they could to combat it. In most cases this lack of prevention is due to the belief that treatment requires great dedication. But this is not the case. Small daily actions, such as drinking plenty of water and avoiding tight clothing, are a good starting point to combat cellulite. Read More
