Should I Really Continue Photo RF when I Get Dark Shade in 2 Weeks After the Session? (photo)

I got my 1st Photo RF in Aug to treat acne. During the session, I got dark spots already and the rest of the day I had burning sensation. After 3 to 4 days, the scab was starting to fall off and got new pink skin. After 2 weeks, I started to see dark shadow where I had dark spot and got scared but as my esthetician told me I had 2nd session in 3wks. Same thing over. Shadows back in 2 weeks. She says I need to continue to get rid of it. So painful because of retinol cream? Skin texture worse...
