Kangmei plastic surgery experts said: within 24 hours after injecting hyaluronic acid into the chin pad, try to avoid touching or being hit as little as possible to prevent the chin from being deformed. However, not everyone is suitable for injecting hyaluronic acid to enrich the chin, nor is it suitable for pregnant women or lactating women, as well as people taking muscle relaxants and special allergies, so as to avoid the failure of surgery. This is the manifestation of the side effects of hyaluronic acid on the chin.
