How long can makeup be applied after hyaluronic acid injection is closely related to the patient’s physical condition, the way of injection and other factors, and makeup can be applied after 48-72 hours under general circumstances. Hyaluronic acid injection is divided into sharp needle injection and blunt needle injection: the trauma of sharp needle injection is smaller, recovery is faster, and makeup can be applied after 48 hours; while the trauma of blunt needle injection is larger, recovery is slower, and makeup can be applied only after 78 hours. Of course, the specific time should be judged according to the patient’s physique. For example, if the skin type is more sensitive, makeup should not be applied when the injection site is still red and swollen. In addition, when applying makeup, it is necessary to pay attention that the makeup should be applied gently and should not be kneaded with excessive force to avoid displacing the hyaluronic acid. It is recommended that patients who have had hyaluronic acid injections should try to put on makeup a few more days apart if they do not have the need to do so, and return to the dermatology or plastic surgery department of the hospital in time for a review if discomfort occurs after makeup application. In addition, after the injection of hyaluronic acid, you should pay attention to rest, eat a light diet, avoid spicy and stimulating food, and try not to touch the injection site.
