Hi there. I've had 4 fraxels. For acne scarring. AFAIK, there are 3 strengths, I'm not sure which I had, the 2nd one I think. It was moderately sore. They put numbing cream on your face (Emla), and my dermatologist also gave me 2 Solpadol (paracetamol+30mg codeine pr tablet, i.e. a fairly hefty dose), PLUS a Valium 5mg. Yes, I was fairly, ahem, relaxed. Then they do the laser. Even with the meds it does hurt a bit. First few hours were ok, overnight my face became quite red and a bit puffy (they give you antihistamines to take to help this). Your face then starts to feel 'rough', over about 4 days it all settles and you have v smooth skin. As the rough skin 'settles', freckles and pigmented patches fall off also. They tell you it's fine to work, and I did, but I felt a bit red and noticeable for the first 2 days. No one said anything to me, I work with a v polite bunch!! The effects continue for about 6 months. You have to be v religious about sunscreen as your face is more delicate. Why spend all that money....
Results? I probably need another 4 sessions, but just can't prioritise the money for it ATM, hopefully I will do. I'm hyper-critical of my scarring so I'm not the most objective assessor, but there is an improvement, not dramatic, unfortunately. As a side effect my skin texture is very good, and I think my crow's feet (charming term) are improved, a bit younger looking skin, or maybe I mean my skin looks well for its age. Skin tone also more even. I think it's v good for pigmentation. I would love to do another few sessions.
Whew! Apologies the long post!
