This depends on your current skin quality.
Older, looser skin tends to settle down quickly; you can expect bumps across the face which will settle usually within hours to half a day. Needle marks might be present and can be seen for a few days.
Younger, more taught skin tends to take slightly more time to settle – the bumps of hyaluronic acid can take between half a day to 2 days t completely settle, but needle marks go quicker in younger skin.
In general, make sure you have no social activities for 2 to 3 days after the procedure, especially if its your first time trying the procedure out.
