Make up/skin care help for 14 years old?

hmm so i started wearing make up when i was
12-13 and i also started wearing liquid foundation (everyday)
since september but i stopped as i think im too young
to wear it ? and i dont really need it + it might just damage my skin.
now i just wear face powder for everyday basis but
i notice that its making my face really dry
(ofc, i know thats what powder can do to ur face)
so is it okay if i use moisturising cream on my face to get rid of this dryness?

any makeup/skin care tips for a 14 year old girl (turning 15 (:) ?
