RevoriaAfter the initial swelling subsides from the treatment (which would be about three to four days– perhaps less), little if any improvement will be noted. After two weeks, considerable improvement will be noted. After a couple of months pass, the gradual production of collagen and the thickening of the dermal tissues will be evident. The improvement can continue for up to six months. After a treatment, it is recommended not to follow up with a second treatment for at least three months. It isn’t dangerous, but may not be necessary.
