I understand the histamine release is the cause for swelling after a Halo facial. H1 (Claritin) and H2 (Pepcid) are sometimes recommended to help with swelling. I did have significant swelling after my first Halo but had great results. My question is, am I better off to avoid these medications to get the best results from Halo? If I decrease swelling using these medications will I also decrease Collagen production after Halo?
