Labo Estri'as with Striadene the first and only local treatment on the stria the investigators of Labo has elaborated and the patented first and only local treatment to apply on the stria. Particularly effective cradle is a formula in the new active complex denominated Striadene. The main characteristic that an effective cosmetic preparation must have to favor the reduction of the striae is the capacity to stimulate the cellular reproduction of the conectivo weave in the affected zones. The reproduction of weaves is stimulated by the Matricinas and the Saccharomices lysate of Striadene. Thanks to this stimulation, the cutaneous weave recovers in the zone of the stria, where the fibers have disappeared or lost their function of subjection. Stimulating effect of the cellular reproduction of weaves the stimulation is developed by the Matricinas and the Saccharomices lysate. The Matricinas is peptide fragments able to regulate the cellular activity. The two Matricinas de Striadene take part in the synthesis of the skin matrix, specially of the colágeno, the main protein of the conectivo weave, and the fibronectina, molecule responsible for the connection between the extracellular matrix and the cellular supercifie. In addition, the two Matricinas promote the cellular proliferation of the queratinocitos and the fibroblasts. For that reason they are effective in the reconstruction of the extracellular skin matrix. The Saccharomices lysate is a rich biotechnological ingredient in amino acids that obtains from the culture of the Saccharomices leavening cerevisiae, that activates the regeneration of weaves stimulating the renovation of the corneous layer. Its application leaves smoothest, smooth the skin and compacts. Labo Estri'as has properties still more thanks to the other components of Striadene. The Tocoferol and the Sericina exert a hidratante and polishing effect. The extract of Aloe side carries out tranquilizing and lenitiva an action. The extract of sanguinea Delesseria stimulates the cutaneous microcirculation. The properties of the components of Striadene are coaduvadas by the strong own eslastizante action of the oil emulsion, rich of germne of wheat. Hidratante effect and polishing East effect is developed by the Tocopherol and the Sericina (protein of the silk). The Tocoferol or Vitamina and protects lipids and lipoproteins of cellular membranes, reason why it benefits the capacity to maintain the water of the skin. It improves the functions barrier of epidermis reducing the loss of transcutánea water. For that reason it is considered like "natural hidratante" for the skin. The Sericina is the second protein of the silk, after fibroína. Equipped with filmógenas but nonoclusivas properties, it leaves smooth and aterciopelada the skin. By its structure and chemical composition, the Sericina can improve the structure of the cutaneous hidratación. In addition, the Sericina has demonstrated to exert a noticeable polishing effect attenuating the cutaneous irregularities. Tranquilizing effect and lenitivo East effect obtains by the action of the extract of Aloe side. The plant of Aloe is well-known by its tranquilizing, lenitivas and hidratantes properties. In addition it has very interesting healing properties for the treatment of the striae. The rich polisacarídica composition confers to the product hidratantes and humectantes properties. Stimulating effect of the subcutaneous microcirculation is developed by the Extract of sanguinea Delesseria, red alga that grows in the North Atlantic. It favors the cutaneous microcirculation, reactivating it locally. It restores the local microcirculation contributing to nutritious substances and oxygen, and improving the trofismo in the areas affected by striae.
