i had 2 scarlet 3 infini apart every 4 weeks - Is it okay to take the last infini treatment? Or too much?

i had for my face and nick 2 scarlet treatment march and april , then i started on may june july 3 infini tratment apart every 4 weeks..is that okey to take the last infini treatment? or too much and hard for my skin? because i already paid for its package? ^_^ hmm i dont know the result sometimes i see tighting in my skin and improvement in my jaw line which is my goal....sometimes i see nothing.. the reason i started with scarlet because at that time i had not heard about infini.
