Radiesse is a dermal filler made of calcium hydroxylapatite, and it is commonly used to treat wrinkles and add volume to certain areas of the face. The presence of lumps or inflammation after Radiesse injections can have various causes, and it's crucial to differentiate between them. Here are a couple of possibilities:1.) Inflammation: Some level of inflammation is common after dermal filler injections, including Radiesse. This can cause redness, swelling, and tenderness at the injection site. It's usually temporary and should resolve within a few days to a week. Massaging the area gently, as recommended by your healthcare provider, can help distribute the filler evenly and reduce any unevenness.2.) Granuloma Formation: Granulomas are small, firm, and sometimes painful lumps that can form in response to certain substances, including dermal fillers. They are essentially a type of immune response to a foreign substance. Granulomas can develop days, weeks, or even months after the injection. If you suspect granuloma formation, it's essential to consult with a dermatologist or a healthcare provider who specializes in cosmetic procedures. They can confirm the diagnosis and recommend appropriate treatment options.3.) Allergic Reaction: While allergic reactions to Radiesse are rare, they can occur. Allergic reactions might manifest as redness, itching, hives, or swelling beyond what is expected after the procedure. If you suspect an allergic reaction, it's important to seek immediate medical attention.In any case, if you are experiencing persistent or worsening symptoms, it is essential to contact the healthcare professional who administered the Radiesse injections or consult a dermatologist for a proper evaluation and guidance. They can help determine the cause of your symptoms and recommend appropriate treatment options. It's important not to attempt to self-diagnose or self-treat in such situations, as it could potentially worsen the condition or lead to complications.
