What is the best antihistamine and post-treatment cream for Excel V laser treatment?

there is no best antihistamine, in my office we give claritin or allergra with ibuprofen, those that swell alot can use medrol packs. but its best to just cooling masks and LED therapy as you want the swelling from vascular laser that helps the ultimate outcome (see link).  Best, Dr. Emer.

Excellent choice of treatment for generalized redness!  This laser works really well to target vessels and helps immensely.  Swelling afterward is usually a good sign that the inflammatory process has started and your body is workin to repair or absorb those vessels.  Usually an antihistamine such as allegra or claritan is good, and if you need some help falling asleep at night, a benadryl before bed can kill 2 birds with one stone.
Unfortunately there really is nothing that you can apply topically that will help the body absorb those vessels.  TNS is expensive and not worth (imo).  Sometimes niacin containing products are helpful but there is no "slam dunk" .  Your body just has to do the work!
Hope this helps.
