Hi Violeta,
I agree 100% with Dr. Lupo. In addition, every patient is a unique case and settings should vary depending on age, skin type, condition being treated, desired downtime, etc. This is why you should see any experienced dermatologist that does these procedures everyday. I have never had a patient not see improvement after treatment with these devices. Another issue is that often times it is best to use multiple lasers in one treatment session to get the best result. If you look at the photos that I have posted on RealSelf, you will see that using the correct lasers in the right combination will yield great results. Take care, Dr. Groff
