Using Nair for the first time..

Jo
So I purchased Nair because I am tired of shaving. My hair grows back so fast & my bakini area & underarms especially always get ingrown hairs (embarrassing & annoying).. So I figured Nair would help, thanks to a lot of lovely ladies saying they love it on here.. I just tested it out.. Did a small portion on my right leg, left it on for about 4-5 min.. I should have left it on probably one more minute.. So then I did my knee down on my left leg.. Left it on for 7-8 min... Scared to leave it on longer because it says do not exceed 10 minutes... Well, it got some hair off but not the rest.. How long do y'all leave it on for? Is it okay to exceed 10 minutes? I haven't tested my underarms yet & I bought the Nair specifically for your bakini area (haven't tested that either, trying to wait for it to grow a little more since I just shaved Friday).. It did however leave my legs soft! But any advice would help since I'm clueless over here & scared to burn my skin 😂
