Dual toning is said to be more effective than pico toning for freckles and blemishes under the eyes, so 10 sessions was too much of a burden, so I paid 540,000 won for 5 sessions at the event price and received it for the first time yesterday. It was worth it without the anesthetic cream, and the doctor was nice because he kindly explained each step during the procedure. I don't know yet because I think the effects will become clear if I continue to use them! The hospital is clean and I would like to get another procedure.
