The precautions after Botox injection include local care, dietary care and exercise care. 1. Local care: after the injection of botulinum toxin, avoid touching the injection site, do not rub your face with your hands, otherwise it will easily lead to botulinum toxin dispersion enhancement, and do not apply ice and heat to the injection site within today. 2. Dietary care: after Botox injection, try to eat a light and digestible diet to avoid spicy and stimulating food, avoid eating seafood and other foods that are easy to cause allergies, and temporarily avoid eating hard food. 3. Exercise care: after Botox injection, avoid doing strenuous exercise within 24 hours, such as playing basketball, fast running, so as not to affect the effect of the injection. If there are obvious discomfort symptoms after Botox injection, such as skin allergy, you should consult the doctor in time.
