Yellow feel that you're talking about I would assume that you are refereeing to retinoid peel which has 4% retinoic acid as the concentration. If you had increased darkening after the peeling session it could be because you did not use sunscreen routinely and effectively after the procedure. If used for the right medication and of a good brand yellow peel can offer good results. Hope this was helpful.
