What should I do if I have an allergic reaction after receiving a hyaluronic acid injection?

Hydroquinone injection is a common cosmetic treatment designed to improve skin hydration and luster by injecting a mixture containing hyaluronic acid, vitamins, and amino acids into the deeper layers of the skin.

Allergic reactions are common complications following the injection and may manifest as symptoms such as redness, swelling, itching, and warmth of the skin. These symptoms are usually caused by an individual's allergic response to certain components in the hydroquinone injection. The occurrence of allergic reactions may be related to the patient's skin type, sensitivity, and the specific ingredients in the hydroquinone formulation.

Firstly, patients are advised to immediately discontinue the use of any products that may trigger an allergic reaction and seek medical attention as soon as possible. Physicians may administer antihistamine medications to alleviate allergic symptoms, and corticosteroid drugs might be required if symptoms are severe. Additionally, patients should avoid scratching the affected area to prevent secondary infection. Before undergoing any cosmetic treatments in the future, it is essential to perform thorough skin testing to ensure no allergic reaction to the ingredients involved.

After the allergic reaction subsides, attention should be paid to selecting appropriate cosmetic products suitable for one's skin type and sensitivity level to avoid recurrence of allergic reactions. At the same time, maintaining good lifestyle habits and skincare routines can help enhance skin resistance.
