Hypopigmentation on legs and bikini

Hello everyone!
I had my 4th laser tretament done on alexandrite 2 months ago. My skin was slightly tanned and I got quite serious burns with blistering all over. Now that blisters are all healed up, I’m left with hypopigmented patches around treated follicles. This worries me a lot since I hear that hypopigmentation can be permanent… By the way, I’m skin type 4 (mediteranian).
Would it be fine to use self-tanning lotion to even out my tan now, 'cause it looks as if I have some kind of fungal infection!!!
Thanks guys.
