“25% TCA Home Peel but my Skin Didnt Peel”

I purchased a home 25% TCA peel. A friend and I did it at the same time. 2 days later her skin started peeling the it was supposed to but mine already 4 days later has no signs of such peeling.

I definitely got extremely dry and wrinkled but it did not really peel, just some very small particles looking like i am peeling off from a day at the beach. My skin got crusty but not as much as my friend's. I have darker skin than hers and was wondering if this was a factor in it. But i dont really believe so. So, my skin didnt really want to peel, it was just looking old.

I decided and took microdermabrasion crystals and washed my face with them to help the dead skin to fall off. It definately helped but i dont know if i should get a real microdermabrasion few days from now to get me completely rid of that dead layer of skin or i should repeat the tca peel. I dont know how safe it is to repeat it a week after i did it once.
