Hydro-mesotherapy is a minimally invasive cosmetic procedure that involves injecting hyaluronic acid, vitamin C, and other nutrients into the deep layers of the skin to achieve effects such as skin hydration, skin brightening, and improvement of skin texture. Redness, swelling, pain, and infection after injection may be caused by incomplete disinfection during the procedure, improper technique, or individual allergic reactions. Specific adverse effects and complications may include skin bruising, swelling, redness, pain, subcutaneous pigmentation, and spots.

The hydro-mesotherapy injection process may cause damage to the skin, leading to symptoms such as bruising and swelling. If disinfection during the procedure is inadequate or post-operative care is improper, wound infection may occur, resulting in symptoms such as redness, swelling, pain, and skin warmth. Frequent injections may compromise the skin's protective barrier, causing skin sensitivity and sensations of prickling or itching. Infections may also lead to subcutaneous pigmentation, causing uneven skin tone or the appearance of pigmented spots. Uneven injections may cause skin irregularities, affecting aesthetics.

Patients are advised to be cautious when choosing hydro-mesotherapy. It is recommended to undergo the procedure at reputable medical or cosmetic institutions to ensure safety and professionalism during the injection process. Before injection, individuals should fully understand their skin condition and the potential risks involved, avoiding impulsive decisions. After injection, strict adherence to post-operative care instructions provided by the physician is essential, including maintaining cleanliness and dryness of the injection area to prevent infection.
