It is generally recommended to wait one week before having sex after a facial injury has been treated with sutures. Facial wounds usually recover in about 7 days, so it is recommended to have sex after one week if you want to have sex after facial suture treatment. If you have sex too soon, you may be too excited during sex, which may cause the wound to reopen or become infected, which will have an adverse effect on the healing of the wound. After the facial suture, you should pay attention to keep the wound area dry and the skin around the wound clean, eat a light diet, prohibit spicy and other stimulating foods, quit smoking and alcohol, which is conducive to the recovery of the wound.
