    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

    Skin types: the water-oil balance

    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

    Bacteria as a spray for skin hygiene

    30 Oct Bacteria as a spray for skin hygiene

    Caring for the skin without washing improves its appearance. Or so claims an AOBiome study, presented in early October in Washington, that points to the beneficial effects of spraying the skin with Nitrosomonas eutropha, a bacterium that metabolizes ammonia in sweat to eliminate body odour.

     

    A company called AOBiome has launched a bacterial spray in the market that theoretically could save water and improve the appearance of the skin. The invention, called AO+ Refreshing Cosmetic Mist, is not exactly cheap: 99 euros for a month’s supply and 249 euros for three months’ supply. But apparently it’s worth it. In fact, its creator, David Whitlock, who says he hasn’t showered in 12 years (!!), argues fervently that Nitrosomonas may be a solution for acne and for chronic skin wounds. Read More
