    Sunburns triple the risk of skin cancer

    21 Nov

     

    Sunburn is dangerous. It may increase the risk of skin cancer, even though we may have been burned – as children – before we were aware of the consequences. We have been warned time and again, but we still see skins red as tomatoes from the sun.

     

    That’s why some organizations continue to emphasize informing the consumer. This Cancer Research (UK) video explains what happens to cells when the sun damages them and the difference with other burns caused by hot objects. The other burns heal, but burns from the sun can have dramatic consequences many years later. Contact burns merely destroy some skin cells, nothing more. Sunburn also destroys cells, but it also alters the DNA of surviving cells and this can lead to the development of cancer. A simple but enlightening reason not to forget to protect yourself from the sun. Read More

    Flying: it wreaks havoc on the skin

    When you fly, pressurized air in the cabin sucks out the moisture in your skin, leaving it feeling dry and looking dull and lacklustre. The haggard complexion on landing is directly proportional to the length of the flight. What can we do to protect our skin so that we don’t look drained when we land?

     

    Cabins are pressurized using low-humidity conditioned air to create a safe and comfortable environment for passengers and crew flying at high altitudes and protect them from the risk of physiological problems caused by low outside air pressure. But in fact flying do affect the skin. The main repercussions for the skin on the face and the body arise from dehydration: dry skin, cracked lips and dry throat, nose, eyes and hands. The body also responds to jet lag and fatigue by releasing the stress hormone cortisol, which impairs the skin's barrier function and causes redness, blotchiness and breakouts. Read More

    Resveratrol helps control acne

    It is known for its reparative potential and sold as an anti-wrinkle agent, but according to a new study published in Dermatology and Therapy, resveratrol also helps cure the unsightly pimples that appear on the skin. Especially when combined with benzoyl peroxide, an antimicrobial agent widely used in anti-acne creams.

     

    The alliance of opposites: Resveratrol is an anti-oxidant and benzoyl peroxide is an oxidizer. But together they seem to be effective in fighting acne. This is the conclusion of research by scientists in the dermatology division of the David Geffen School of Medicine at the University of California (UCLA), who claim that resveratrol enhances the bactericidal effect of benzoyl peroxide and inhibits growth of the Propionibacterium acnes bacterium responsible for acne over a longer period (over 24 hours). Additionally, the formula is not harmful to the skin. Read More

    You may have thick or thin, flaccid or firm skin, and be more or less sensitive to the sun’s radiation. But the cosmetics industry and most of the population refer to people as having normal, dry, oily, combination or sensitive skin, without really understanding where to draw the line between each category. What’s normal skin? What makes complexion more or less greasy? How can we decide what skin type we have and what products to use?

     

    We are born with our skin type – what physicians call a phototype. It’s our type for life, although it’s also true that the environment, stress, diet and hormonal changes at different life stages (adolescence, pregnancy or menopause) can change the skin. However, skin types are mostly classified on the basis of the nature of the hydrolipid film coating the skin’s surface (made up of water and fat) that helps to maintain the skin’s barrier function. What makes this film, also referred to as the skin’s mantle or emulsion, vary? Read More
