Do I need any type of gel for IPL hair removal? I have just purchased the "Remington I-light Reveal hair removal system.

I have PCOS and I have been shaving my chin for about 10 years, the hair is just getting worse as it does when shaving. I am so self conscious of this and my self-esteem has hit rock bottom, I have started having panic attacks when going out in public, that's how bad its got! I cannot afford professional hair laser treatment, which is why I bought this one. I am willing to try anything but have heard so many horror stories of scarring, burns etc. Any advice would be much appreciated!! Thankyou!
