I actually had a combo Yag/Erbium laser resurface. It was quite painful. I felt as if I were on fire for nearly an hour. I also experienced hyperpigmentation on my chin and between my eyes.
To be honest, I regretted every single second of this procedure.However, I am now nearly 4 months out and love what I look like. It was worth it. Just know that the deeper they go, the longer the healing process. If you expect immediate results, this isn't for you. Give it time and work with your doctor. I look 10 yrs. younger.
