Tissue necrosis: if the injection amount is too large or too concentrated, it may lead to skin tissue necrosis, leaving scars or pigmentation.

Allergy: Some people may be allergic to hyaluronic acid, with symptoms such as redness, itching and rash.
Local swelling and pain: after injection of hyaluronic acid, discomfort symptoms such as local swelling and pain may occur.
