I bought this 1 1/2 years ago and just have never used it. You are to stay out of the sun and tanning bed pre and post use and I'm not good at that 😅. There are mixed reviews online about the effectiveness of it, it's suppose to have results with consistence use in 3-4 weeks and full results with touch ups at 12 weeks. It's certainly a cheaper try than $2000-$4000 laser treatments... I bought it on sale for $200 from Ulta Beauty. It is still in box with pamphlets and directions. I never actually used lol I pulled it out of the box like twice.
