What Kind Of Reactions Can Occur After Cosmetic Filler Injections?

Reactions to filler agents are rare and generally resolve with time. Some common injection-related reactions might occur, such as swelling, redness, pain, itching, discoloration and tenderness at the implant site. They typically resolve spontaneously within several days after injection into the skin. Other types of reactions are very rare, but occasional patients do experience localized reactions thought to be of a hypersensitivity nature. These have usually consisted of swelling at the implant site, sometimes affecting the surrounding tissues. Redness, tenderness and rarely acne-like formations can be seen.
