I just got SimsPE downloaded because I've heard that it can do a lot of things like make custom shaped clothes and different hair styles. I've also just heard that it can change eye colour and skin tone

I just downloaded an eye colour and skin tone that would perfectly fit my Sim's style, and all I know is that SimsPE can change the eye colour and skin tone. how do you do that? I've tried finding how to do that on Google, but it was all just confusing zero help. do any of you people out there know how to do this?
