IPL Laser Tissue Damage

From your description and the time lapse since your IPL, the changes of your facial skin may be related to rosacea and possible coexisting dry sensitive 'rough' texture skin known as 'keratosis pilaris haemorrhagica faciei'' (dry, red patches on the face with a prominence around hair follicles that may look like 'milia'). This may be improved with additional IPL treatments at higher energy, topical moisturizers and anti-inflammatory creams.

IPL is a superficial level skin treatment and does not go very deep into the skin. It treats the epidermis and upper dermis and would likely not cause you these problems. Maybe this condition existed in a undeveloped state before and is responsible for the face veins that then lead you to get treatment. Could you be getting some progression of something like rosacea? I think you should get a dermatologist to have a fresh look at you. I think the IPL is a red herring.

You should go see a good dermatologist for advice. It does not sound to me like your problems are related the the IPL treatment.
