i have done some research on self administrating botox and it doesnt seem to difficult. there are facial muscle maps all over the internet showing the muscle groups and where to inject. its more about how much i think then anything else. trentinoin is the only thing that is proven to work on skin it comes in three strengths 0.025 0.05 and 0.1. i use 0.05 every evening. try the 0.025 first that may work for you. retinol or retin a that you buy over the counter doesnt work it is completley way to weak
