Stretch mark removing essence lotion and preparation method thereof

Technical Field

The invention belongs to the field of essence milk and a preparation method thereof, and particularly relates to essence milk for removing striae gravidarum and a preparation method thereof.

Background

Striae gravidarum is a remarkable physiological change of skin at the parts of abdomen, buttocks, breasts and the like during pregnancy, and is caused by the fact that subcutaneous elastic fibers are lengthened (mainly transverse) or broken, the skin is thinned, capillaries are exposed and partially broken, subcutaneous bleeding is caused, irregular purplish red tortuosity stripes are formed, and a corresponding striae gravidarum (95.9% -98.4%) is left after one delivery. It is in the form of fresh stripe during pregnancy, and can be gradually absorbed after parturition, and its color changes from purple or light red to grey-white or silvery-white. Over time, the length of the fiber is substantially constant, the stretched fiber retracts, the width tends to narrow, the broken fiber does not heal, a scar is formed, and the whole life is left behind, but the width is wider. Due to individual differences, it is possible that the width of the stretch marks 3 years after delivery of the first person is the same as the width of the stretch marks 1 year after delivery of the second person, or the same as the width of the stretch marks 5 years after delivery of the third person, but the colors are different.

The control method of striae gravidarum is prevention and repair of striae gravidarum. Preventing diseases such as training body before pregnancy, eating more food rich in protein, enhancing skin elasticity, maintaining proper motion and balanced nutrition after pregnancy, and preventing excessive weight gain. The method for repairing the striae gravidarum is mainly characterized in that the striae gravidarum is repaired by a surgical removal method and a medicine repair method, the surgical removal method is quick in effect, but causes damage to the body of a parturient, and the cost is high; but the medicine has poor repairing effect and slow effect.

In response to the above problems, researchers have achieved better results through skin surface improvement. For example, chinese patent CN108175740A discloses a repair cream with the efficacy of effectively preventing and removing stretch marks and a preparation method thereof, wherein the repair cream comprises the following components by weight percent: 3-6% of blackcurrant seed oil; 2-4% of shea butter; 3-6% of olive fruit oil; 2-4% of cocoa butter; 5-10% of methylsilanol hydroxyproline ester aspartate; 3-10% of pseudoalteromonas fermentation product extract; 13-6% of acetyl tripeptide; 2.5-5% of collagen; 2-4% of a centella asiatica extract; 11-2% of oligopeptide; 10-20% of beta-glucan; the repair cream has excellent achievement in the aspects of striae gravidarum size reduction and color lightening.

One of the major pathophysiological triggers of complex stretch marks is inflammation, so it is possible during pregnancy to reduce stretch marks by destroying inflammation. The asiaticoside and the asiatic pennywort herb (CENTELLA ASIATICA) extract have excellent function of repairing skin inflammation. The avenanthramides in the extract of the kernel of Avena sativa (AVENA SATIVA) can inhibit the degradation of keratinized cell nuclear factor NF kappa B-alpha directly related to inflammation at a certain concentration, so as to prevent the phosphorylation of p65 protein subunit on the cell nuclear factor NF kappa B, and block the generation process of cell inflammation. In addition, the oat alkaloid can inhibit the activity of NF kappa B degrading enzyme induced by tumor necrosis factor TNF-alpha and reduce the release of inflammatory factor IL-8. A certain content of asiaticoside, centella asiatica extract and oat kernel extract synergistically repair inflammation, and the inflammation repair effect brought by the asiaticoside, the centella asiatica extract or the oat kernel extract is better than the sum of the inflammation diminishing effects brought by the asiaticoside, the centella asiatica extract or the oat kernel extract alone.

In addition, the skin penetrating agent of the invention, namely the ethylhexyl triazone, can promote asiaticoside, the snow grass (CENTELLA ASIATICA) extract and the oat (AVENA SATIVA) kernel extract to permeate surface skin to reach inflammatory cells, scar tissues, fibroblasts and the like, so that the asiaticoside, the snow grass (CENTELLA ASIATICA) extract and the oat (AVENA SATIVA) kernel extract play a role in repairing striae gravidarum.

Comparative example 5

According to the Chinese patent CN108175740A, the comparative example provides a repair cream with the efficacy of effectively preventing and removing striae gravidarum, and the components of the repair cream in percentage by weight are as follows: 5% of glycerin, 683% of M, and 3% of blackcurrant seed oil; 2% of shea butter, 3% of olive oil, 2% of cocoa butter, 2% of vitamin E, 10% of methylsilanol hydroxyproline ester aspartate; 5% of collagen; 20% of beta-glucan and 10% of pseudoalteromonas ferment product extract; acetyl tripeptide-16%; centella asiatica extract 4%; oligopeptide-12%, acyl ketone 0.5%, 1, 2-hexanediol 0.5%, and water in balance.

Striae gravidarum removal tests were as follows:

160 pregnant mothers, pregnant woman with new striae gravidarum and 22-35-year-old volunteers are selected and divided into 8 groups, the striae gravidarum removing products in examples 1-3 and comparative examples 1-5 are respectively used, the volunteers divide the abdomen into two areas by taking the midline of the abdomen as a boundary, one side of the two areas is selected as a using part of the striae gravidarum removing product according to a random principle, and the other side of the two areas is used as a control part. One stretch mark of similar severity was taken on each side and labeled for clinical assessment of target lesions. The striae gravidarum removing products in examples 1-3 and comparative examples 1-5 are respectively used for massaging the abdomen of a volunteer for 3 months, the frequency of use is 1 time/day, and the use amount is 5-10 g/time. Clinical judgment criteria: four items such as the overall repair of striae gravidarum, the area of the striae gravidarum, the color of the striae gravidarum, the sag of the striae gravidarum and the like are evaluated, meanwhile, a score of 6 is adopted for scoring (0-5), a score of 5 represents a perfect state, a score of 0 represents a severe state, an average value is taken, and the using result is shown in table 1.

TABLE 1

As can be seen from Table 1, the products of examples 1-3 had a relatively good striae gravidarum removing effect. When asiaticoside, an asiatic centella extract, ethylhexyl triazone or an oat kernel extract are not added in the essence milk, the effect of removing the stretch marks is greatly reduced, and particularly, the asiaticoside, the asiatic centella extract or the oat kernel extract are not added, so that the asiaticoside, the asiatic centella extract and the oat kernel extract have the effect of synergistically increasing the effect of removing the stretch marks, and the effect of removing the stretch marks is directly influenced by the addition of the ethylhexyl triazone. Although the product in the comparative example 5 has the effect of removing the striae gravidarum which is similar to that of the invention, the two compositions for removing the striae gravidarum are different, comparative example 5 is methylsilanol hydroxyproline aspartate, collagen, beta-glucan, pseudoalteromonas ferment extract, acetyl tripeptide-1, centella asiatica extract and oligopeptide-1, whereas example 3 of the present invention is asiaticoside, centella asiatica extract, ethylhexyl triazone and oat kernel extract, the only thing that is the same is centella asiatica extract, but the invention utilizes the synergistic effect of asiaticoside, asiatic pennywort herb extract and oat kernel extract, namely the combination of the asiaticoside, the asiatic pennywort herb extract and the oat kernel extract is essential for removing the striae gravidarum effect, meanwhile, ethylhexyl triazone can increase the effect of removing stretch marks, which is quite different from comparative example 5.
