    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

    Skin types: the water-oil balance

    5 Nov Skin types: the water-oil balance



    Le Figaro Santé


    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

    Winning the battle against skin dehydration

    30 Sep Winning the battle against skin dehydration



    Dermatologic Therapy

    Our skin contains natural ingredients that protect it and keep it hydrated. These substances form the outermost layer of the skin (the stratum corneum). When the functioning of this outer shell is disrupted, our skin loses water. Dry skin is a common problem that is tricky to resolve. But why does our skin become dry?


    We wash too often, use highly alkaline soaps and expose ourselves to excessively dry air from heating and cooling devices. Often we lead a lifestyle that does not allow the skin to follow its natural regeneration cycles. We know that hydrated skin is essential for the epidermis, most especially its outer protective layer, to retain its structure and function properly. When its barrier function is altered, the skin loses water and shrivels like a leaf, which is when we notice discomfort and even itchiness. In short, the skin dries out. Read More

    Sunscreen against wrinkles

    15 Jul Sunscreen against wrinkles



    Annals of Internal Medicine

    Summer is here and many people are planning to buy the traditional sunscreen to take to the beach. We all know that this is how to protect our skin from photoageing and how to minimize the risk of serious related disorders. A new Australian study confirms that people who use sunscreen have fewer wrinkles.


    Some people – although not many – use a sunscreen (or a cosmetic containing sunscreen) daily on parts of the body exposed to the negative effects of sunlight on the skin. Others do not use sunscreen, or only do so occasionally. A group of researchers has finally confirmed what dermatologists have long known: the sun causes wrinkles and dry skin. The study, which included 900 volunteers aged between 25 and 55, was conducted over four and a half years in Australia, a country with a mainly white population that receives a great deal of sunshine.
