    Dermatitis caused by cosmetics

    14 Apr

    Certain ingredients used in cosmetic products often produce allergic contact dermatitis of the skin. Valencia University Hospital has conducted a review of 740 patients diagnosed over a period of seven years.  The cause was cosmetics in 27.3% of these cases.

     

    Contact dermatitis causes itchiness and rashes and even burn-like reactions. The study concluded that the cosmetics that most often caused problems were hair dyes (18.5%), gels (15.7%) and moisturizers (12.7%). Doctors tested the study patients for 46 known allergens. Those most important reactions were caused by methylisothiazolinones  (19%), which are used as preservatives, the colourant paraphenylenediamine (15.2%) and perfumes (7.8%).

    Skin-deep emotions

    13 Apr

    Our skin reveals our feelings to the world. The face is said to be the mirror of the soul. And the skin of the face never lies. We blush when we feel embarrassed, we get goosebumps when we feel strong emotions and we break out in a sweat when we are scared or nervous. All these reactions, reflected in the skin, give us away. We have no control over them.


    Picture the skin as a sponge that absorbs sensations rather than water. And picture the skin as a mirror, except that, unlike a mirror reflecting images, the skin reflects our feelings and the internal reactions of our bodily organs, especially our brain. Read More

    Candies that scent the skin, the latest in “beauty from the inside out”

    4 Apr

    A Bulgarian confectionery company has launched a rose-perfumed sweet. Once eaten, the sweet gradually releases the fragrance through the pores of the skin. And the sweet is not fattening since it does not contain sugar.

     

    The idea originated in Japan where geraniol-scented chewing gum has long been available on the market. The rose aroma, as well as flavouring the gum, can also be percieved in the skin. Geraniol is a colourless liquid found in plants such as rose, vanilla and lavender. Uptake and subsequent release through the skin occurs as in garlic, long known to function in this way. The creators of the innovative sugar-free sweet maintain that this is the first in a series of nutricosmetic products that could soon have their own market segment.
