Swelling is usually worse in the morning, so it can help to sleep with head elevated. Also antihistamines can help reduce the swelling, I recommend non sedating antihistamine, Zyrtec or Claritin, during the day and Benadryl at night.
Hi, thank you so much for posting! I actually just had an IPL 3 days ago, we used the 1540 non ablative hand piece on me and I am still swollen like a chipmunk. A few tricks to help are icing it, 10 mins on, 10 off a few times per day, avoid salt and drink lots of water. Sleep on your back and with extra pillows, as the day goes on you will notice swelling goes down but its the worse in the AM, if you sleep with extra pillows under your head you dont give gravity the chance to accumulate the fluid. Give it a few days, the swelling will calm and you will see the gorgeous glow :)
