The side effects of Lanluma treatment are very rare, especially if the treatment is performed by an experienced facial plastic surgeon. The rare side effects include tenderness, redness, bruising and swelling. One of the very possible delayed side effects of Lanluma treatment is the formation of the small lumps under the skin, nevertheless, this rare side effect can be eliminated by injecting the Lanluma correctly deep into the skin and followed by a delicate but firm massaging of the treated areas immediately after the injection and patients should continue massaging the treated areas of the face twice a day for 5 days.
