Liposuction is the most widely used cosmetic surgical procedure to remove fat from beneath the skin. However, several studies question its effectiveness and usefulness. The biggest problem is that patients quickly replace the fat removed, but not always at the site from where it was removed.
According to recent studies, subcutaneous fat removed by liposuction is recovered in many cases as visceral fat, which cannot be easily removed. But it has also been demonstrated that 40 minutes of medium intensity exercise three times a week for four months after liposuction ensures proper redistribution of body fat and avoids negative side effects.
Hyaluronic acid is one of the stars of what are called nutricosmetics, an alternative for reducing skin wrinkles, they say, to more aggressive treatments like Botox. It comes in the form of injections, gels or pills that are worth their weight in gold. But does hyaluronic acid really work? What are the side effects?
Originally used as an egg substitute in baking and later to treat diseases of the connective tissues that surround and hold most internal organs in place, hyaluronic acid is a polysaccharide naturally present in our body that holds water in cells and tissues in a percentage equivalent to a thousand times its weight. This confers hyaluronic acid with an interesting redensifying and moisturizing potential that the cosmetics industry is exploiting to the full. Read More
The fashion of removing pubic hair has gradually come to be a widespread practice nowadays, especially among women. The origins of this trend may be the desire to attract the opposite sex, a mistaken perception of hygiene or even an attempt to return to childhood. But more and more doctors advise against this practice.
Pubic hair has the important function of naturally easing friction between folds of skin in the most intimate parts of our body. Genital hair removal, irrespective of the method used (waxes, razors, creams, electrolysis, etc) irritates and inflames the hair follicles and causes multiple microscopic wounds. The natural moisture in these areas fosters pathogenic bacteria proliferation and the resulting abscesses and pustules. Recent medical reports, moreover, confirm that hairless genitalia are more vulnerable to herpes and other sexually transmitted diseases.
When we tan, melanocytes (skin cells) produce melanin, a pigment that protects our DNA from the harmful ultraviolet rays of the sun. Scientists have now discovered that the melanocytes also produce a light-sensitive element that accelerates tanning.
UVB rays increase melanin production within a few days of exposure to the sun. UVA rays, however, trigger this process within minutes. The reason is that UVA rays also cause melanocytes to produce rhodopsin, a light-sensitive molecule found in the retina, which, within 24 hours, multiplies the amount of melanin produced by five. This mechanism is our “emergency” defence system against aggression from the sun.
