None! You can leave the clinic after the procedure and carry on as normal. Some pinkness may be present for an hour or so after. Lips and eyeliner can cause some swelling but this subsides after 24hrs.  If you have an important event or trip away Hannah asks that you plan accordingly for this as no makeup can be used on the treated area while healing and aftercare involves cleansing the area and applying the provided lotion that is included in your after care. Further to this swimming and heavy sweating is not permitted during the healing period.
