Step. 1 ratio
Hyaluronic acid lysase exists in the form of lyophilized powder, and generally needs to be prepared before use.
Take a bottle of lysozyme, draw about 3ml of physiological saline and inject it into the bottle, dissolve the dry powder, shake and dissolve completely; Use a 1ml syringe to extract 0.3ml of dissolved lysozyme;
Add physiological saline to dilute it to 1ml, and fully mix it (or use a 2.5ml syringe to dilute it to 1ml, which is more uniform).
Step. 2 Skin test
Take 0.02ml of 150u/ml solution for intradermal injection. If there is a rash with pseudopodia within 5 minutes, lasting for 20-30 minutes, and there is itching feeling, it is positive. However, transient erythema in local area is caused by vasodilation, which is not positive.
Step. 3 Injection
When injecting, first determine the depth and width of the injection, try to inject it into the middle of hyaluronic acid, and inject it evenly in multiple directions, so that there will be no unevenness after dissolution. When the depth is not accurate, it should be shallow as far as possible. It can also dissolve most of the hyaluronic acid by penetrating under the skin and relying on drugs.
Note: Press for a few minutes after injection to avoid swelling. It will be stable in 1 to 2 days.
