For the use during procedure - go over a stroke that is too long or our out of place; use with sponge applicator or microbrush and glide over couple of times to work the product in gently. After healing this stroke will not be visible. For best results use on freshly made mistake, but can be successfully used even days after procedure (you will need to reopen the incision gently. We do not recommend using on large areas or on fully healed skin.
