The “Lip Pop” technique, also known as the “Lip Flip,” is a nonsurgical cosmetic procedure that uses Botox injections to relax the upper lip muscle and flip the lip, creating a fuller and more pouty appearance. The procedure involves a few small injections of Botox into the muscle near the lip border, which allows for a subtly fuller and smoother appearance of the upper lip. This procedure is especially suitable for those who want a fuller upper lip but do not want to use dermal fillers. On the other hand, lip filler augmentation is a cosmetic procedure that uses injectable dermal fillers to give the lips a fuller, plumper appearance. This procedure involves injecting a filler into the lips, which can range from temporary to longer-lasting results. There are potential risks and side effects associated with both procedures, including infection, asymmetry, and migration of the filler. Therefore, it’s important to consult with a board certified dermatologist and discuss any concerns or questions before undergoing any cosmetic procedure.
