Broken capillaries are worse, and they've spread after laser resurfacing. What can I do?

Any treatment inducing inflammation which would include laser, peels, and surgery, can increase the appearance of capillaries.  This is not only related to the inflammatory reaction which dilates vessels (commonly temporary over a period of weeks or months) but also to the rerouting of blood through vessels which preexisted but were not evident.  In any case rejuvenating lasers generally are not ideal for treating capillaries although they may help.  Lasers created specifically for vessel treatment which might include a KTP laser, a pulsed dye laser, and others would be more effective for the vessel treatment area.  Three weeks it is insufficient time to see the final result.  I would suggest waiting another 3 weeks and returning to your physician or another person  who has the capability of treating the capillaries.
