Will antihistamines slow collagen stimulation if taken for swelling after Halo laser?

Antihistimines shouldn't hurt your results at all. We've been using it in 100% of our patients for 4 1/2 years and people get great results. If having a terrible histamine reaction helped produce collagen, I would move somewhere with a wretched allergy season and have beautiful skin around my eyes and nose!People do debate back and forth (there isn't a good study to answer the question) on whether steroids are a good thing or awful - derms tend to love them and plastic surgeons pale at the thought. The good news is that with elevation, cool compresses, H1&2 blockade, most people never need to use steroids.

Antihistamines are very helpful with HALO and other laser treatments to minimize swelling which also minimizes discomfort.  Your results speak for themselves!  It will not impede your results but will make your healing process smoother.  HALO is an amazing hybrid fractional laser technology.
