Will Lumenis CO2 laser cause more broken capillaries if I seem to get them easily lately? (Photo)

Co2 laser doesn't improve blood vessels, if anything it can make it worse if dont too agressively.  You should have the yellow laser, pulsed dye or IPL done at the same time.  Best, Dr. Emer.

The CO2 will not diminish the broken capillaries and may make them worse.IPL (Intense Pulsed Light) is the treatment to correct the broken capillaries. IPL can also help calm down the redness in the skin and diminish the broken those capillaries.

Thank you for including photographs!  All CO2 lasers--different brands, fractional, standard--are associated with a certain amount of redness post-operatively.  Standard (non-fractional) CO2 laser treatment and deeper treatment levels, used to eradicate deeper acne scars and deeper wrinkles, usually causes more redness of the newly-healed skin and possibly for a longer time.  It is not typical to have development of broken capillaries after CO2 laser.  This is an issue you should address with your plastic surgeon prior to treatment.  CO2 laser usually renders beautiful resurfacing results, but the healing and the resolution of the redness is a bit of a commitment, and it does take a bit of patience.  Best wishes for a result you love!
