Description

Composition containing ectoin and application thereof in laser beauty treatment

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a composition containing ectoin and application of preventive and reparative anti-inflammatory effects of the composition in laser cosmetology.

Background

Nowadays, the pursuit of people for beauty is continuously promoted, the technology in the field of beauty is continuously improved, and laser beauty is one of the effects of beauty treatment. Laser therapy relies on the thermal action of high-energy light waves to selectively and effectively destroy target cells and avoid damage to surrounding normal tissues, and is currently used in the fields of pigment pathological changes, wrinkle removal, photon skin tendering and the like. Although laser beauty has the advantages of good curative effect, less side effect, high safety and the like compared with the prior beauty technology, the laser beauty still needs postoperative care and has the defects of postoperative complications.

Postoperative complications are mainly inflammatory reactions including edema, exudation, scabbing, redness, erythema, etc. Redness of the skin results from vasodilation, which tends to produce pigmentation, which generally resolves longer and is more difficult for yellow people to resolve than for white people. Erythema occurs mostly during the healing process of wounds, and if erythema is too hard or healed too long, hypertrophic scarring may occur. Most of the existing treatment methods are to repair laser beauty complications by applying or taking medicines after operation, such as (1) dexamethasone is orally taken after operation to relieve swelling; (2) biological synthetic semitransparent dressing or topical antibiotic ointment is used for absorbing wound surface exudate and moisturizing, and healing is accelerated; (3) after operation, the vitamin C synthetic cream or sunscreen cream, hydroquinone cream and moisturizing cream are applied for sunscreen and moisturizing. But few options exist for pre-operative prophylaxis.

According to literature reports (Simon et al 1995), Hsp70 overexpression can significantly reduce the release of IL-6 induced by UV-A, UV-B and oxidative stress, thereby performing cell protection and repair, and protecting cells from infection, inflammation or various injuries. In addition, ectoin has the effect of inducing the over-expression of Hsp70 gene (Buomino et al 2005), and after the addition of thermal stimulation to cells treated by ectoin, experimental results show that the synthesis of Hsp70 of human keratinocytes is increased, and proinflammatory cytokines IL-1a, IL-6, IL-8 and TNF-alpha are down-regulated, thereby showing that the ectoin has anti-inflammatory effect.

Aiming at the characteristics that the ectoin promotes the overexpression of Hsp70 so as to obviously reduce inflammation and resist heat action and the like, the invention prepares a mixture containing the ectoin, which can be used before and after laser treatment and furthest reduce complication symptoms in the aspects of diminishing inflammation, removing swelling, easing pain and preserving moisture. Publication No. CN110215461A discloses a medical cosmetic formula, which mainly comprises hyaluronic acid, polylysine and vitamin C; publication No. CN104474577B also discloses a medical beauty formula, which mainly comprises hyaluronic acid, yeast essence and bright peptide antibacterial liquid, but the medical beauty formula is only used for skin repair after operation and carries out repair and nursing on inflammation and wounds which have already occurred. Publication No. CN106420399A discloses a mixed reagent, wherein a nursing agent 1 is used in preoperative operation, a nursing agent 2 is used in postoperative operation, most of the components of the nursing agent 1 with a prevention function are humectants, an anti-inflammatory effect substance is glycyrrhetinic acid, and prevention effect data are not given in the examples. Publication No. CN105477342A discloses a traditional Chinese medicine repair cream for post-operative whitening repair, which contains various traditional Chinese medicine extracts such as centella asiatica and ligusticum wallichii, but the natural plant extracts contain unknown side effects or adverse reactions under synergistic effect. The publication No. CN110141627A discloses a formula for wound care, which comprises aloe gel, propolis and the like, but has the effects of sterilization and pain relief, has no obvious anti-inflammatory effect and is also used for postoperative care. Thus, there is a need to develop a formulation that can be used to prevent laser cosmetic complications.

The photodamage pretreatment experiment shows that the main factor influencing the proliferation activity of human keratinocytes is ectoine, oligomeric sodium hyaluronate is inferior, and the macromolecular sodium hyaluronate has a certain effect, but has a poor effect compared with the oligomeric sodium hyaluronate and a tiny effect of sodium dermatan sulfate; the synergistic effect of the first three substances is greater than the effect of compounding the ectoin with one hyaluronic acid, and the synergistic effect of the dermatan sulfate is small. When the concentration of ectoin is 2.5 percent and the concentration of oligomeric sodium hyaluronate is 0.5 percent, the effect is best, the damage effect is greatly reduced, and the composition has a good effect of preventing laser light damage. In a repairability experiment, the four components have good effects and synergistic effects, and the composition has good anti-inflammatory and repairing effects on laser photodamage.

Both experiments show that the secretion amount of the proinflammatory factor IL-6 at 47 ℃ is larger than that at 37 ℃, and the IL-6 concentration at 37 ℃ is basically unchanged in each sample group due to the fact that the temperature at 37 ℃ is the normal temperature of a human body. In the thermal injury pretreatment experiment, at 47 ℃, the sample groups all produce resisting effect, the ectoin effect is most obvious, the high-molecular sodium hyaluronate and the oligomeric sodium hyaluronate have certain preventing effect, the dermatan sulfate sodium effect is small, the four substances have synergistic effect and mainly take the ectoin. When the concentration of the ectoine is 2.5%, the IL-6 concentration is the minimum, the damage effect is greatly reduced, and the ectoine has a good effect of preventing thermal damage. In a repairability experiment, the four components have good effects and synergistic effects, and the composition has an anti-inflammatory repairing effect on laser thermal injury.

Experimental example 3 preparation of spray provided herein

1. The formula is as follows: 2.5% of ectoin, 0.3% of high-molecular sodium hyaluronate, 0.5% of oligomeric sodium hyaluronate, 5% of sodium dermatan sulfate, 5% of butanediol, 3% of glycerol, 3% of propylene glycol, 2% of betaine, 0.1% of allantoin and the balance of water.
