For crepey neck skin, two of my favorite treatment options are microneedling and Radiesse! Microneedling helps stimulate your body's natural collagen production, improving skin texture, thickness, and overall quality over a series of treatments. Hyperdilute Radiesse is a biostimulator that works differently than traditional filler. Rather than adding volume, it encourages your body to produce new collagen and elastin, which can help improve crepiness, firmness, and skin quality over time. I typically recommend combining the two treatments to optimize results. This doesn’t replace surgery but is a good way to see gradual improvement over time as new collagen develops. I hope this helps!
