Hydro needle treatment may have side effects such as mild swelling and bruising, skin irritation and inflammation, skin fragility and sensitivity, and allergic reactions. A detailed analysis is as follows:

1. Mild swelling and bruising: After hydro needle injection, mild swelling and bruising may appear on the face for several days. This is due to trauma to the skin tissue during the injection process, leading to local circulatory disturbance and subcutaneous bleeding.

2. Skin irritation and inflammation: Hydro needle injections may irritate the skin surface and cause traumatic inflammation. In cases of sensitive skin or improper injection technique, the inflammation may be more severe. This inflammation may lead to symptoms such as localized redness, swelling, pain, and itching, and in severe cases, may affect normal skin function.

3. Skin fragility and sensitivity: After hydro needle injection, the skin may enter a sensitive and fragile phase. This is because the small needle punctures cause some damage to the skin, compromising its natural barrier. During this phase, the skin becomes more susceptible to external stimuli, and adverse reactions such as redness and stinging may occur when using skincare products.

4. Allergic reaction: Some individuals may be allergic to ingredients in the hydro needle solution, such as hyaluronic acid or vitamin C. Symptoms of allergic reactions may include skin itching, redness, swelling, rash, and in severe cases, life-threatening symptoms such as difficulty breathing and shock may occur.
