I recently started using oil at night and I really love it, but I'm not sure how to combine it with serum. Serum first then oil or vice versa? Or should I just use the oil at night and serum in the morning?
personally i would use the oil at night and the serum in the morning. I use Alpha H glycolic acid stuff in the evening and boots serum in the morning under my moisturiser. I would imagine too many products will not give good effects. Im no expert though!
