Following your SkinPen treatment, the treated area may appear pink and mildly inflamed (similar to a mild sunburn). After the procedure, your provider may advise you to keep your skin free of cosmetics or sunscreen for the remainder of the day. Consult your provider if you are prone to herpes simplex outbreaks, such as cold sores, about ways to prevent or whether the procedure is right for you. If your treatment area has irritated skin (sores, open wounds, sunburn), please contact our office the day before your appointment. Please note that we cannot perform this procedure with active breakouts. Consult your provider before your SkinPen procedure if you have any concerns. SkinPen procedures should be delayed at least six months following isotretinoin use, since isotretinoin may interfere with wound healing. Talk to your provider if you have recently used self-tanning lotion or spray before your SkinPen procedure. Avoid sun exposure for 24 hours before the procedure. Before the SkinPen procedure, you should stop using topical products that contain AHAs, retinol, or vitamin A. Ask your specialist if the procedure is right for you if you are on autoimmune therapy.
