    Collagen is the main fibrous component in the skin and bones. A quarter of the protein mass in our body is collagen, which forms 75% of the connective tissue. Collagen acts as the scaffolding for our skin. One cause of sagging skin is reduced collagen content. Collagen injections are used mainly to fill in areas of the face that have lost firmness and become wrinkled due to the passing of time. The main function of collagen is as a filler material for empty spaces in the deeper layers of the skin, thereby eliminating the fine lines that so many people dread. Read More

    Syndets: soapfree soaps

    7 Jan Syndets: soapfree soaps

    Nowadays we are no strangers to skin care concepts like ai???cleansing barsai??? and ai???dermatological barsai??? as the cosmetics industry has managed to develop ai???soapfree soapsai???. We wash our hands with bars that contain no soap and our gels are ai???soapfreeai???. Soapai??i??s day has passed: welcome to the ai???syndetai???.

     

    Soap is the result of a chemical reaction (saponification) between a fatty acid and an alkaline base. If quantities are not right, the reaction produces alkali remains and a basic pH soap that is detrimental for our skin. But even a perfectly formulated and manufactured soap is distinctly alkaline in an aqueous medium. Read More

    ai???Handcraftedai??? soaps: beware!

    5 Oct

    Who has not bought ai???handcraftedai??? soaps? They are to be found everywhere, whether in specialist shops, in street markets and on the Internet. Naturally, we all want the best for our skin. But we are often driven by irrational impulses when we buy and our choices are not always right.

     

    It seems that what belongs to the past is always better and, right now, handcrafted goods are chic. In a rushed world where we all wear the same clothes, buy the same food and use cloned cosmetics, handcrafted goods seem to reflect a ai???slowai??? culture, with products that are meticulously made, unique, very personal and very ai???healthyai???. And this retro movement in the cosmetic sector is waving the ai???handcraftai??? flag for products "free from harmful chemicals.ai??? Beware, however, because this powerful marketing claim is not entirely innocuous and its compliance with legislation on cosmetics is borderline. Read More

    To exfoliate or not to exfoliate?

    17 Jun

    Since ancient times it seems to have been accepted that a healthy, flawless skin, free of dead cells, needs regular exfoliation. This body care ritual can be performed using products containing abrasive particles, layers of gomage which are then peeled off or creams with specific ingredients. Peeling, dermabrasion, scrubbing ... is exfoliation a necessity or an aberration?

     

    The outside layer of the skin is the epidermis, whose cells originate in the basal layer (which separates the epidermis from the dermis). These cells gradually migrate to the surface and then die. Healthy skin is renewed every 30 days. Aged skin has a longer renewal cycle. Read More
