The most common side effects are swelling, discomfort, tenderness, soreness, and bruising. Some patients experience an altered sensation, which typically goes away. You may experience redness and bumps in the area, hyperpigmentation, and numbness or tingling. There is also a risk of ulcerations, rashes, scarring, and infection. To prevent a side effect known as tight banding, we give you stretches, which patients should start 3-4 days after their procedure.
