Had my 3rd and final RX laser treatment done today, this round burns and throbs 10x worse than first two. How can I ease this?

Im not sure whatoyu mean by "last" laser, in my practice treatment plans include lasers every month to maintain collagen production.    Please be on the proper post-procedural care at this time.

For facial rejuvenation I would suggest a combination approach of :

1) skin care with products and PRP/microneedling
2) PDT light therapy few times a month with growth factors
3) laser treatments like clear and brilliant regularly and a few times a year Fraxel, Viva, Co2/Erbium
4) Sculptra injections a few times a year for collagen production with fillers like juvederm/restylane/belotero/radiesse/bellafill
5) thermage/ultherapy for yearly skin tightening with or without PDO or cone based instalift threads for lifting
6) botox every 2-3 months to stop movement lines and prevent lines at restBest, Dr. Emer.
