Good Day. Thank you for your question. I appreciate your uncomfortable feeling from itching, which can be quite anxiety provoking.You did the right thing taking Benadryl 50 mg. You can also repeat this regimen three times a day.It is unusual for my patients having the Venus Viva to experience itching. Pink hue to the skin and mild facial swelling for 1-4 days is expected. The itching may probably means skin dryness.To optimize the treatment outcome and minimize post-treatment erythema (redness), dryness, swelling, and discomfort the following helps: (Sunblock, cold compresses and moisturizers are standard) 1. Patients own serum growth factors from their blood (PRP) immediately after 2. Using Alastin extracellular matrix modulator serum of ten days post-treatment 3. Thereafter, using human stem cell derived growth factors such as Stemulation or Regenica for 6 weeks.I was in the group of physicians who participated in the investigation review board (IRB) study to assist in FDA clearance. We performed before and after skin biopsies in ten patients that showed increased skin thickness and increased collagen synthesis to rejuvenate the skin. In summary, the Venus Viva combined with the post-treatment serums, growth factors, and moisturizer will optimize your result and smooth your skin. Good luck with these recommendations, I believe the itching should arrive in less than 24 hours.
