Problems solved by technology

Japan has already applied PPP subcutaneous injection cosmetic projects. Although the injection of PPP colloidal plasma is a safe and efficient filling material, it is the same as hyaluronic acid or collagen, and the maintenance effect is short.
In addition, there are no products made of PPP for external use on the skin, which are used for skin care, especially for skin care after laser surgery.

[0025] The preparation method of PPP

[0026] 1) Centrifuge the blood sample once, centrifuge at 1400-1600rpm for 8-12min, take out the platelet-rich plasma (PRP) in the upper layer, and obtain PRP once;

[0027] 2) Centrifuge the above primary centrifuged PRP for a second time at 2800-3200rpm for 18-22min to concentrate the platelets so that the final concentration of platelets reaches 800×10 9 ~1200×10 9 per L; the supernatant obtained after centrifugation is PPP (platelet-poor plasma).

Embodiment 1

[0029] The preparation method of embodiment 1 PPP

[0030] The specific steps of obtaining PPP at the same time when preparing PRP are as follows:

[0031] 1) Whole blood routine test (platelet count);

[0032] 2) Perform a centrifugation according to the specific situation of the patient (generally, women use 1500rpm, 10min), and use a sterile syringe to separate the upper layer of platelet-rich plasma (PRP) to obtain a centrifuged PRP;

[0033] 3) Take 50 μl (microliter) of the primary centrifuged PRP obtained in the previous step for platelet count;

[0034] 4) According to the counting results, the above-mentioned primary centrifugal PRP was divided into two parts, the first part was reserved for the last; the second part was subjected to secondary centrifugation (3000rpm, 20min) to concentrate platelets, so that the final concentration of platelets reached 1000×10 9 / L; the supernatant obtained after centrifugation is PPP (platelet-poor plasma), take it out and transfer...

Embodiment 2

[0035] The preparation method of embodiment 2 PPP

[0036] 1) Centrifuge the blood sample once at 1500rpm for 10min, and use a sterile syringe to separate the upper layer of platelet-rich plasma (PRP) to obtain PRP once;

[0037] 2) Centrifuge the above primary centrifuged PRP for a second time at 3000rpm for 20min to concentrate platelets so that the final concentration of platelets reaches 1000×10 9 per L; the supernatant obtained after centrifugation is PPP (platelet-poor plasma).

Abstract

The invention discloses the application of platelet-poor plasma in skin care. The present invention finds that PPP has a good skin care effect through research, especially in skin care after laser treatment, has a significant promotion effect on wound healing, and has no adverse reactions such as allergies; in addition , Applying a mask containing PPP not only protects the wound, but also nourishes the wound, accelerates cell proliferation and tissue repair. The preparation of PPP can be obtained at the same time as the preparation of platelet-rich plasma PRP, making full use of blood samples, and the preparation operation is simple and fast.

Description

technical field [0001] The present invention relates to the application of platelet-poor plasma in skin care. Background technique [0002] With the continuous advancement of laser technology, it has been widely used in facial rejuvenation treatments, such as freckle removal, whitening, etc. Laser beauty has become a huge industry and is still growing. However, after laser facial treatment, the skin will show increased reactivity or inflammatory reaction, resulting in postoperative complications such as local erythema, edema, itching, burning sensation, and pain, which will cause troubles for patients. According to clinical observation, it takes about 7-10 days for the skin wounds produced by laser treatment to recover. Therefore, post-laser repair has become an indispensable part of laser cosmetology. In addition to conventional ice packs, sun protection, moisturizing and other nursing measures, various post-laser repair products have also sprung up one after another, whi...
