Lip threading, also known as a lip thread lift, is a nonsurgical cosmetic procedure that uses small dissolvable threads to enhance lip shape, definition, and contour, mainly focusing on the cupid’s bow and lip border. Before and after the procedure, lips typically show increased definition, lift, and slight volume enhancement, resulting in a more natural and refined appearance rather than the plump, pouty look from fillers. The threads also stimulate collagen production, which improves lip texture, symmetry, and can reduce fine lines around the mouth. Immediately after the procedure, some swelling, bruising, and minor asymmetry from temporary inflammation may be present but usually resolves within about a week. The threads dissolve in about three to six months, but collagen stimulation effects can last from six months up to a year or longer, maintaining a subtle enhancement over time. The procedure requires minimal downtime, and lips have a natural-feeling texture after healing. Visual comparisons of lip threading before and after typically show lips with more defined borders, a lifted appearance, smoother texture, and an overall more youthful look without added bulk.
