    You have probably heard of the wonders of laser skin treatments and so may be asking if laser could help overcome some of the effects of ageing that start to become increasingly visible as you grow older. Be guided by a reputable dermatologist who will advise you regarding the treatment best suited for your skin type and condition — and also for your pocket.

     

    Laser advances are most especially being made at the cosmetic end of the spectrum, which means they are less invasive than traditional treatments like chemicals peels and dermabrasion. However, if you are considering some kind of laser or light-based treatment for your skin, it is extremely important that you consult a dermatologist or specialist centre. Be sure to ask about side effects, recovery times, number and frequency of treatments, any pre- and post-treatment skincare requirements. Read More

    The concept of personal hygiene has always been associated with issues as diverse as health, morality and beauty. Maybe that's why the history of the toilette is full of surprising advances and retreats. Understanding how hygiene evolved gives us insights into humanity and our current personal care practices.

     

    1. Cleanliness is (next to) godliness. The ancient Egyptians attached great importance to bathing — and also to natural body odours, which were accentuated with special perfumes for the genitals. The first bathtub on record dates from around 1700 BCE in Ancient Greece, while the invention of the steam bath is attributed to refined sybarites of the 8th century BCE. The fact that the word “hygiene” comes from the Greek goddess Hygeia is hardly surprising, as this goddess — of healing and cleansing — was especially popular during the plagues that devastated Athens in the 5th century BCE and Rome in the 3rd century BCE.

    Daily care of dry skin

    24 Dec Daily care of dry skin

    Understanding our skin and its needs should be the basis for our choice of cosmetics, so if you have very dry skin, you need to use products that are specifically formulated to treat dry skin and that also take into account your life stage. Below we provided some basic guidance for people with very dry skin.

     

    Dry skin has various causes, among them, genetics, aggressive drugs, overexposure to cold or sun, natural ageing, etc. But dryness is always the result of two factors: lack or excess loss of water (dehydration) and deficient sebum secretion by the sebaceous glands. A healthy, elastic, comfortable-feeling skin requires an optimal level of water in the stratum corneum. Certain components in dry skin are altered, but can be restored by suitable cosmetics. Hydration is the best way to maintain youthful skin and delay the onset of signs of ageing. Read More

    Just over a year ago we published scientific evidence on the effectiveness of sunscreens against wrinkles. Since then the cosmetics sector has included sunscreen in many products, like make-up, with good results. The message is clear: sunscreen is crucial. Always.

     

    In June 2013, the Annals of Internal Medicine published the results of a major study, conducted in Australia over four years, which underlined that wearing sunscreen daily helps prevent wrinkles. In fact, the study, a milestone for professionals in terms of duration and scope, underlined that a sun protection factor (SPF) of 15 is more effective than taking nutritional supplements, such as beta-carotene, to preserve the skin.
