All laser devices used around the eyes and face carry a theoretical risk of damage to the eye surface and so protective shields covering the eyes are used at all times. Certainly, in inexperienced hands, even the least invasive laser device can be very dangerous so you must ensure that your laser professional has expertise. Although some degree of post-treatment discomfort, tightness, swelling, and redness can sometimes occur, long-term risks are rare. Such risks include hyperpigmentation, hypopigmentation, scarring, skin retraction, infection, persistent blurry vision, and chronic dry eyes. Such risks are avoidable by careful patient selection and pre-treatment planning. You should tell your laser professional about any active infection, medical issues, current medications, smoking history, or a history of recurrent cold sores. If you are currently smoking it’s best to stop at least 2 weeks prior to laser therapy.
