anybody on trimming facial hair??

I posted a message a while ago about trimming facial hair, and I got a few responses, but they weren't really responding to what I asked (thanks anyway though). I don't want to take any supplements, and like I said the facial hair i have is fine and blonde and there is not a whole lot of it, so i don't think i really need to take anything...I just want to know if trimming, not shaving, facial hairs will make them worse (you know, grow faster, longer, or darker, or more noticeable). Would appreciate a response!!
