Description

Compound essential oil for removing striae gravidarum and preparation method and application thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to compound essential oil for removing striae gravidarum, and a preparation method and application thereof.

Background

Stretch marks are one kind of stretch marks, and the stretch marks are skin fiber breakage phenomena generated in the processes of pregnancy, body building and sudden weight increase of a human body, and are usually red, white or purple stripes. Stretch marks including fat marks and sports cracks are likely to occur in body parts with large movement amplitude, and in addition to the abdomen, the stretch marks also occur in body parts such as the inner and outer sides of the thigh, the knees, the buttocks, the lumbosacral and the like.

The abdominal wall tissues of the human body are respectively skin, elastic fibers of the skin, a subcutaneous fat layer, rectus abdominis composed of muscle fiber groups and muscle tendons, a preperitoneal fat layer and peritoneum from outside to inside. Under normal conditions, the elastic fibers of the skin keep a certain elasticity with the rectus abdominis and can freely stretch and contract within a certain limit. However, when the female is pregnant for more than 3 months, the enlarged uterus protrudes from the pelvic cavity and develops to the abdominal cavity, the abdomen begins to swell, the skin elastic fibers and abdominal muscles begin to extend, the stretch is more obvious after 6 months of pregnancy, the skin elastic fibers are gradually broken, and the surface of the abdominal skin slowly appears pink or purplish red irregular longitudinal cracks. After production, the broken elastic fibers are gradually restored, but are difficult to restore to the former state. The original skin cracks gradually fade and finally become silvery-white striae gravidarum.

There are many reports on stretch mark repair products in the prior art. CN108434024A discloses a horse oil stretch mark resistant repair cream and a preparation method thereof. The repair cream comprises horse oil and sodium alginate oligosaccharide, wherein the horse oil and the sodium alginate oligosaccharide account for 2-18% of the total weight of the horse oil stretch mark-resistant repair cream. The horse oil and the sodium alginate oligosaccharide are combined for use, so that the skin care product can effectively nourish each cortex, accelerate skin metabolism and enhance cell activity, can effectively activate epidermal growth factors, can improve the growth of human keratinocytes without manually increasing the epidermal growth factors, is integrated with the human keratinocytes, and is matched with other raw materials to enhance cell activity, promote the repair and synthesis of collagen and elastin, and improve the elasticity of skin, thereby realizing the effect of lightening striae gravidarum.

CN106619478A discloses a stretch mark repair essence composition, which comprises the following components in parts by dose: emulsifier: 1-2, water: and the balance, glycerol: 5-6, humectant: 5-7, stretch mark repair compound: 5-7, β -glucan: 2-3, anti-irritant: 0.1, preservative: 0.1-0.2, essence: 0.01-0.02; the raw material components of the stretch mark repairing essence composition provided by the invention are mild in medicine property, obvious in effect, free of stimulation and free of side effect.

CN103316157A discloses a compound essential oil for treating striae gravidarum, which is composed of orange flower essential oil, frankincense essential oil, chamomile essential oil, rose essential oil and grape seed essential oil according to weight components; the essential oil can effectively fade striae gravidarum, and in addition, the compound essential oil has a light and clear herbal medicine costus smell, so that the striae gravidarum is faded, the skin state can be improved, the skin is moistened, scars are faded, the skin is firmed, the skin is shinier and more elastic, and the aromatic smell in the essential oil can make the mood of a patient comfortable and pleasant.

However, related products in the prior art are relatively single in formula, cannot meet the requirements of skin in the gestation period, and have little effect; and the mildness is relatively low, and the contained additives such as mineral oil, pigment and essence components are not friendly to sensitive skin during pregnancy. Therefore, it is very necessary to develop a product which has high safety and mildness, can strengthen the skin, enhance the elasticity and remarkably improve the striae gravidarum.
