Dimpled skin on the chin often comes from overactivity of the mentalis muscle, while loose skin beneath the chin can be due to aging, loss of elasticity, or mild fat accumulation. A combination approach is usually most effective: Botox/Dysport: Small doses can relax the mentalis muscle to smooth out chin dimpling. Dermal fillers: Hyaluronic acid fillers can improve chin contour, reduce dimpling appearance, and enhance overall definition. Skin tightening treatments: Options such as radiofrequency microneedling (Morpheus8), Ultherapy, or laser-based tightening can stimulate collagen and firm loose skin. Kybella (deoxycholic acid): If excess fat is contributing to the fullness under the chin, this injectable can help reduce fat and improve definition. Combination therapy: Often, the best outcome comes from addressing both muscle activity (Botox) and skin quality (tightening devices or fillers). These treatments can be tailored to smooth the chin surface and improve the contour under the chin for a firmer, more refined appearance.
