First time user. Mid 50's, never a smoker and no blood thinners. Wanted to eliminate smoker's wrinkles and fill in deeper lines around mouth. Four syringes later with immediate swelling and bruising. First photo is two hours after I left the doc's office and the second was after seven days. At two week mark, bruising was no longer noticeable. However, many small circular bubbles (similar to small blisters, but not painful), remain on the underside of my top lip. No injections were made into my lip! Doc wants to see me again in three weeks (which would be five weeks after treatment).
