Should Skin Blister After Postdye Laser Treatment?

Thank you for your question. This is not typical and is going to raise the risk of skin discoloration.  You should notify the office and should be vigilant with your sunscreen.  Be certain to be under the supervision of a board certified dermatologist or plastic surgeon with expertise in laser surgery for the most effective and safe treatments. I hope this helps.

Pulsed dye laser, whether 585nm. or 595nm. very rarely can induce blistering.  There may be multiple factors why this would occur including multiple pulses in one area, high fluence (energy) and immature surgical scars are more sensitive than mature scars. Gentle cleansing and application of an occlusive ointment may help minimize textural change. Depending on the natural color of the skin, there may be a chance of developing post inflammatory hyperpigmentation. If someone has developed a blister after V-beam laser they should contact their doctor to see what regimen of skin care would be appropriate for them.

Normal reaction to a pulsed dye laser treatment can include erythema (redness), soreness, and  edema (swelling).  A pulsed dye laser is typically used to treat scars or vascular birthmarks or tumors and helps to decrease the red discoloration of the skin.

Blistering to any laser treatment can be concerning for possible adverse side effects.  Even ablative treatments (resurfacing treatments) usually do not produce blisters. Blisters can be a sign of either a treatment that was very aggressive, or possibly an infection or an allergy to topical treatments.

Bottom line, you need to be seen by your physician to receive proper diagnosis and treatment to help prevent the situation from worsening.
