Too much hyaluronic acid will produce the following conditions:
1. Injecting more than 20ml of hyaluronic acid at a time will cause excessive swelling and stiff expression, because hyaluronic acid fills the skin volume to make your skin full. Filling too much hyaluronic acid in the same part at a time is easy to cause swelling, excessive skin tension and stiff expression.
2. Hyaluronic acid injected into blood vessels has serious consequences.
Hyaluronic acid injected into blood vessels has really serious consequences. Generally, blue-red skin, red-white skin and blue-white skin will appear during injection or within half an hour after injection, and swelling and pain may also occur. If these conditions are not treated in time, the skin will turn red within 3- 10 days after injection, and local tissue degeneration and necrosis will gradually appear, that is, ulceration. In severe cases, it will lead to eye vascular embolism, pain and blurred vision, then light perception, and then blindness.
Hyaluronic acid is injected into the skin in winter, so don't worry about freezing or dissolving.
Hyaluronic acid injected into human body will not deteriorate with the change of environmental temperature. Hyaluronic acid, once injected into the body, will not change, be gelatinous, harden, freeze into solid or dissolve into liquid.
So how much is appropriate:
Full face: 10 or so, but not more than 20. When it exceeds 10, it is recommended to inject in batches.
Forehead: 2-4 pieces. Generally, people who pay attention to sticking bricks on their foreheads will use more.
Nose: 1-2 or so.
Temple: 1-3 branches/side
Silkworm: 0.5- 1 per side.
Lacrimal groove: 1-2 branch/both sides
Lissolis: 1-2 branch/both sides.
Lip: probably 1. If you want a more exaggerated lip shape, you need to inject it twice, and the injection amount is less than 1ml.
Cheeks: 1-4 branches/sides
Eight-character pattern: 1-2 or so/both sides
Chin: probably 1-2, and if it is very short, it may be 4.
Earlobe: about 1 branch/both sides
Secondly, regular hospitals should not overdo it, and consider it for patients. They won't ignore safety issues like small hospitals in order to make money. Other questions are welcome to consult me.
