Definitions

  • compositions for topical and / or parenteral application comprising, in a physiologically acceptable medium, a retinoid and / or its salts and / or derivatives, and an inhibitor of the degradation of hyaluronic acid.
  • Said compositions are intended for the treatment of dermatological conditions, in particular, the filling treatment of wrinkles, fine lines, fibroblastic depletions and any scarring.
  • the aging of the skin is one of the most visible changes in the senescence process.
  • the skin is exposed to many factors that can accelerate this physiological process.
  • intrinsic aging which is easier to evaluate in areas that are normally not exposed to the sun and, on the other hand, extrinsic aging, caused by the interaction of environmental factors, in particular UV rays. These environmental factors have a much greater effect on sun-exposed body parts, especially in light-skinned people.
  • actinic aging Other factors such as eating habits, smoking, excessive alcohol consumption, Chronic diseases and dysfunctions of the endocrine glands also contribute to this aging.
  • the stratum corneum is little modified.
  • the epidermis is atrophic and the dermal-epidermal junction is flattened, so that adhesion to the dermis is less good, facilitating the formation of bubbles.
  • the thickness of the dermis is significantly reduced; there are fewer blood vessels. There are also fewer fibroblasts and their biosynthesis and proliferation abilities are diminished.
  • the elastic fibers undergo modifications first, and then disappear.
  • Wrinkles are the most visible signs of aging. We can distinguish it from several natures, in particular superficial and deep wrinkles. Deep wrinkles may be due to dermo-hypodermic changes, while superficial wrinkles could be explained by dermal and possibly epidermal changes. Wrinkles are mainly due to the loss of elasticity of the skin. The reaching of the network elastic subepidermal gives rise to a superficial laxity of the aged skin and a fold of its surface. The destruction of elastic fibers in the reticular dermis is responsible for the loss of elasticity and the ability of the skin to regain its shape after stretching. Depending on the type, intensity and topography, a suitable treatment will be possible.
  • dermal implants that is to say as substances injected directly into the skin, in order to remedy the skin changes resulting from aging. , trauma or disease.
  • Botulinum toxin inactivated Botox ®
  • laser techniques These different types of treatment are not exclusive and their combination has even been recommended.
  • collagen and hyaluronic acid are the ones that are at the origin of the majority of the products available on the market.
  • Hyaluronic acid is a ubiquitous natural polysaccharide that exists in the same form from the simplest bacterium to humans. It is a polysaccharide composed alternately of D-glucuronic acid and N- acetylglucosamine, linked together by alternating glycosidic bonds beta-1,4 and beta-1,3. According to Saari H et al. Differential effects of reactive oxygen species on a native synovial fluid and purified human umbilical cord hyaluronate. Inflammation 17 (1993): 403-415, the polymers of this repeating unit can have a size between 10 2 and 10 4 kDa in vivo, the hyaluronic acid taken from the umbilical cord having a weight of 2500 kDa.
  • Hyaluronic acid is a natural component of the dermis where it plays an important role in the hydration and elasticity of the skin. However, it decreases in quantity and quality with age, resulting in drying of the skin that wrinkles. It is highly water soluble and forms high viscosity solutions in water. Because of these particular properties, hyaluronic acid is one of the most widely used pharmaceutical products.
  • hyaluronic acid is very quickly eliminated from the plasma by degradation. Its plasma half-life after intravenous injection is very short, between 2.5 and 5.5 minutes, while in the skin, its half-life is 0.5 to 2 days depending on its concentration. Urinary excretion is low, less than 1% of total clearance. In rabbits, the rate of elimination in the skin was measured (Reed RK, Laurent UB, JR Fraser, Laurent TC., Removal rate of [3H] hyaluronan injected subcutaneously in rabbits.) Am J Physiol 1990 Aug; 259 (2Pt 2): H532-5). It is non-exponential with a half-life of 0.5 to 1 day when its concentration is 5 mg / ml. The tolerance of hyaluronic acid is very good and no immunogenicity has been associated with this substance. This has a very low incidence of side effects.
