In about 4 years, I've had 5 fraxel 5 times and 3 legato sessions. I was very stressed at work, so my menstruation stopped for 7 months . Considering that Fraxel has become common, is Legato an upgrade? I know it happened, but the effect seems to be better with legato, but the principle of both cuts the skin? It makes the skin feel very thin because it is made flat... It's just my personal opinion!!! I have blackheads on my nose. I think that those who take this nose pack and pull out like strawberry seeds will see the Fraxel effect, but it's my personal opinion that Fraxel won't be very effective for those who don't get lumps like seeds but only long sebum like earthworms and threads . It's not that the pores are enlarged and the sebum becomes lumpy, but the sebaceous glands are over-developed.... It's like a puddle, so you can't cut it off to make the skin flat, right?? So I didn't see any effect.... Instead, I noticed a little effect on the marks caused by the trouble, but it didn't have any effect on the nose pores I was concerned about. Please think carefully. The price is a lot cheaper these days.
