I am a 14 year old girl in the UK. Do you think I should be wearing make up at my age?

When I go to school, I wear pressed powder (Pressed Fantasia 24h), Clinique blush, sometimes eyeliner. I usually apply powder in the morning, then during lunch. Do you think this is too much make-up for my age? Are there any natural ways to prevent/get rid of acne breakouts? Do you think this is the main cause of my acnes? Thanks, I just want opinions :)
