What are the side effects of collagen filling in the temporal region? Collagen injection into the temporal area restores volume to sunken temples with minimal trauma and excellent results. However, inadequate pre-treatment preparation or post-procedure care may lead to side effects such as hyperpigmentation, infection, or swelling.
Potential side effects of collagen filler injections in the temporal region include:
① Allergic reactions: A skin allergy test is mandatory before treatment. Individuals testing positive must not receive injections. Even with a negative test, allergic reactions may still occur. Collagen injections are unsuitable for those with severe allergies or a family history of autoimmune diseases.Common allergic symptoms include edema, nodules, tenderness, itching, and erythema. Inflammation, ulceration, or even cystic granuloma reactions have been reported, though extremely rarely. ② Transient non-inflammatory reactions may occur post-procedure, including temporary swelling, mild redness, and slight discomfort. Symptoms typically resolve within 24–48 hours.
③ Mild swelling or intermittent itching around the injection site after drinking alcohol or sun exposure may result from peripheral vasodilation. These symptoms are self-limiting and do not affect cosmetic outcomes.④ Overfilling: If excessive collagen is injected into the temporal region, seek prompt medical attention. ⑤ Capillary Dilatation: The temple area has thin skin, making capillary dilatation possible. This typically resolves spontaneously within a certain timeframe.
⑥ Pigmentation: Generally, injecting too superficially or neglecting sun protection may cause pigmentation. Using a whitening mask 4-6 times after one month can reduce or eliminate this pigmentation.
⑦ Infection: Collagen injection into the temples is an invasive procedure with a risk of infection. If infection occurs, seek prompt medical attention.
