For those who have had fine dark spots removed around the eyes, from which session did your complexion start to brighten?

Dark spots have spread out in a triangular pattern along the thin skin under my eyes, resembling dark circles. Hearing people ask if I look tired several times a day caused me so much stress that I developed social phobia. Even after generously applying eye cream and Vitamin C ampoules, the skin tissue around the eyes is so thin that absorption is poor; instead, I only ended up with bumpy milia. I've heard that the area under the eyes must be handled with extreme caution and cannot be treated with high-intensity lasers due to the risk of blindness or eye irritation, so I'm skeptical about whether pigment toning will actually be effective. Since the skin is thin, I'm wondering if bruising or swelling will last a long time after the laser treatment. For those who have had dark spots removed around the eyes, please share your experiences and tell me at which session your complexion started to brighten.
