    Understanding labels: What’s in my shower gel?

    23 Mar

    Most of us use shower gels for hygiene and daily skin care. There are hundreds of brands and thousands of packages, colours, textures and fragrances. Unless we are experts, reading labels raises many doubts. What are all these ingredients and what effect do they have on our skin?


    The main action of body and facial hygiene products is to remove the dirt accumulated on our skin. We consider a good hygiene product to be one that cleans us and produces abundant foamy lather while not irritating the skin or mucous membranes. In addition to this primary function, depending on the ingredients, gels may also have antiseptic, moisturizing or stimulating effects. But do we really know what’s in our shower gel? Read More

    Yarrow has skin anti-ageing properties

    21 Mar

    A recent study has shown that yarrow, a common plant in the northern hemisphere, increases skin thickness and improves the appearance of wrinkles and pores. This opens the way for use of this ingredient in cosmetic rejuvenation formulations.


    The French scientists who conducted the study  tested around 1000 possible cosmetic ingredients. The yarrow plant (Achillea millefolium) – specifically a 2% extract – showed the best results. Over two months of treatment, the skin of the study volunteers became generally smoother and substantially improved in terms of the appearance of crow's feet, pores and wrinkles.

    What feeds our skin?

    16 Mar What feeds our skin?



    They say we are what we eat. But what are the grounds for thinking that eating chocolate or chips leaves an imprint on the skin? There is plenty of literature on the foods necessary for a healthy skin, but little is known of the effects of certain supplements.


    People who have an allergy literally feel all this in their skin. Food can change the appearance and condition of the mantle that covers the body. And what we eat has a direct impact on how the skin functions. This is because the skin, like any other metabolically active organ, requires water and food to maintain its condition. Read More

    Antibacterial gels: are they necessary?

    9 Mar

    With swine flu, hygiene and personal care became a priority. The fear of contagion meant that antibacterial gels – liquid solutions for hands that prevent germs from spreading – became popular and stocks ran out. But to have a healthy skin, isn’t it better to wash hands with soap and water in the traditional way, as a more inexpensive and safer way to stop bacteria spreading?


    The surface of the skin is one of the most important microbial habitats in the human body. More than 150 different species of bacteria may inhabit just a single hand. Many are harmless and beneficial, but opportunistic organisms responsible for infections and epidemics may also appear. Read More
