Side Effects and Complications
- Dermal Fillers (Hyaluronic Acid):
- Localized Redness, Swelling, and Pain: These are common side effects that typically resolve spontaneously within a few days after injection.
- Bruising: Blood vessels may be damaged during the injection process, leading to localized bruising, which usually fades within 1โ2 weeks.
- Allergic Reactions: In rare cases, individuals may be allergic to hyaluronic acid, presenting symptoms such as rashes and itching; prompt medical attention is required.
- Vascular Embolism: If hyaluronic acid is inadvertently injected into a blood vessel, it can cause vascular occlusion, resulting in severe complications such as skin necrosis or blindness. Although the incidence is low, the consequences are serious; therefore, treatment should only be performed at accredited medical facilities by experienced physicians.
- Autologous Fat Grafting:
- Infection: Strict aseptic techniques are essential during surgery; failure to maintain sterility may lead to infection, characterized by localized redness, swelling, pain, and fever, requiring antibiotic treatment.
- Fat Liquefaction: Some grafted fat may fail to survive and undergo liquefaction, causing localized hardening or swelling that requires further intervention.
- Irregular Contours: Uneven fat distribution can result in facial irregularities, necessitating corrective procedures.
- Fat Embolism: Similar to hyaluronic acid fillers, if fat enters the bloodstream, it may cause vascular embolism and lead to severe outcomes.
