Alexandrite Laser for Fair Skinned, Easily Burned Irish/German - for Getting Rid of Freckles?

I am fair skinned, burn easy. Lots of face freckles. Recently I had IPL with the Sciton Joule laser, 515 filter for freckles.I paid $400 for 1 session.There is a med spa nearby offering a deal for $139 to treat the face.They told me via phone they would use an Alexandrite laser. I am scared of being burned but willing to find the same results for a lot less.It seems as though I will need 1 or 2 more IPL treatments before I get the results I am after. Is the Alex laser okay for fair skinned?
