Description

Targeted scar repairing mesh construction composition and application thereof

Technical Field

The invention relates to the technical field of cosmetics, in particular to a composition for constructing a target repairing scar tissue mesh and application thereof.

Background

Stretch marks refer to the phenomenon of skin fiber rupture of the human body during pregnancy, are one of stretch marks, are white or silvery glossy scar lines, mainly appear on the abdominal wall, and also can appear on the inner and outer sides of thighs, buttocks and the like, and are particularly obvious for the primiparous woman. Striae gravidarum is mainly affected by hormones in pregnancy, and in addition, the abdominal distension causes the elastic fibers and collagen fibers of the skin to be damaged, so that striae gravidarum appears. After delivery, striae atrophicae transform into striae gravidarum. Once it appears, it does not disappear and is accompanied by skin laxity, breast drop, abdominal fat accumulation, which seriously affects the postpartum physical and mental health of women.

Striae gravidarum is light and heavy, and the following methods are common at present: 1. the treatment is carried out by means of laser, the principle is that the laser with specific wavelength and pulse width is emitted to selectively penetrate through epidermis to stimulate an injured collagen layer to generate a new collagen tissue, the new collagen tissue grows at a normal speed to gradually repair the injured collagen layer and improve the texture and the state of the skin, but the method can only be properly lightened, so that the new collagen tissue is not obvious and can not be completely removed, and some postoperative repair treatment is needed after the operation, otherwise, the effect which is proper to the contrary can be achieved; 2. the abdominal skin-pulling operation, namely the abdominal wall plastic operation, recovers the elasticity and the compactness of the abdominal fascia through re-suturing the abdominal fascia, improves the abdominal tension, and can push the contents originally belonging to the abdominal cavity inwards to achieve the purpose of removing the striae gravidarum.

According to the tests, the composition for constructing the target repair scar tissue network provided by the invention utilizes the scientific proportion of the plant active extract compositions such as the India swertia extract, the sweet orange fruit extract, the blue-green microalgae extract, the avocado fruit extract and the like, and various plant active substances cooperate with a target spot to repair, so that high-purity and high-activity effects are exerted on the skin, and the striae gravidarum repair of the accurate target spot repair is realized by applying a cell transmembrane technology; supplementing collagen, enhancing skin elasticity, and accelerating the recovery speed of the broken elastic fibers; four layers of skin have corresponding unique targeting mechanisms from subcutaneous tissue, dermis layer, epidermal layer and cuticle to repair target cells and tissues by aiming at a reaction mechanism.

The composition for constructing the target repair scar tissue mesh has the advantages that the action mechanism is clear, the trouble of striae gravidarum on married and fertile women can be well solved, the composition is based on solving the problem of striae gravidarum, cells are awakened, scar formation congestion is relieved, epithelial cells are activated, subcutaneous cells are acted, deep memory of skin is awakened, various damaged tissues are decomposed by penetrating into a dermis layer, the affected part is prevented from expanding outwards, efficient nutrition is provided to the cells through ultra-strong penetration, the damaged cytochromes are prevented from generating variation, and the purpose of eliminating the striae gravidarum is finally achieved; in addition, the traditional Chinese medicine composition can accelerate abdominal heat energy, consume fat, remove excessive water, promote metabolic function, improve the smoothness and the delicacy of the skin of the waist and the abdomen, increase the toughness of the skin, sculpt an abdominal curve, repair skin water locking, repair skin elastic fibers, promote collagen regeneration, and recover the elasticity, the flexibility and the compactness of the skin.
