You don't need to look online ~ Just look at the best machines in your municipal city ~ The average machines are almost the same ~ The price is about one square centimeter of 220 yuan ~ I'm talking about the price of cold laser ~ There is no scar after cold light washing ~ But if the lines are deep, you can look at the outline ~ You should go to the hospital for free ~ After reading them, they say you can wash them ~ You should sign a contract with them ~ You should read the contract carefully ~

I hope it helps you.
