Is aquaphor 100% safe if I just had Fraxel 1550 done 4 days ago? I'm taking 500mg of vancomycin twice daily.

Aquaphor is occlusive and may be too heavy for your skin. Patients with acne-prone skin may develop white-heads from using Aquaphor after Fraxel. Therefore, to prevent unnecessary clogged pores, I recommend checking with your surgeon about what moisturizer to use and which to avoid post-procedure.
