When considering Radiesse or hyperdiluted Radiesse for areas such as the arms, stomach, or glutes, it's important to understand how these fillers work and their potential effects. Radiesse is a dermal filler made of calcium hydroxylapatite microspheres, which can provide volume and stimulate collagen production. Injections in areas with thicker skin and more subcutaneous fat, like the arms, stomach, or glutes, generally have a lower risk of lump formation compared to areas with thinner skin. Hyperdiluted Radiesse involves diluting the product with saline or lidocaine, which can lead to a smoother distribution and further reduce the risk of lumps or nodules because it spreads more evenly and stimulates collagen production over a larger area. However, the risk of lumps can also depend on the technique used by the injector and individual patient factors. To minimize risks, it is crucial to have the procedure performed by an experienced and qualified healthcare professional who understands the anatomy of these areas and the appropriate injection techniques. If you are considering this treatment, I recommend discussing your specific goals and concerns with a board-certified dermatologist or plastic surgeon who can provide personalized advice and ensure the best outcomes.
