What is a good moisturizer i can get? Also, some make-up tips?

I am 14. I have acne and my skin is always getting very dry, especially around my chin and forehead area. What is a good moisturizer I can buy, preferably inexpensive, which is for acne-prone skin?

Also, I need some good makeup tips. I use Bare Minerals. For brushes I use the Flawless Face Brush, the Full Flawless Face Brush, and the Max Coverage Concealer Brush.

I use the Fairly Light Foundation first, over my whole face, and I apply it with the Flawless Face Brush. Then I use the Fair Foundation as concealer wherever I have red spots and acne. I apply that with the Max Coverage Concealer Brush. Then I put on the Warmth Face Color on my cheekbones, forehead, nose, and chin using the Flawless Face Brush. Lastly I apply the Mineral Veil all over my face with the Full Flawless Face Brush.

Should I wear blush? I use Victoria's Secret Beauty Rush mascara in brown and usually some neutral or light, sparkly eyeshadow with either my Buxom Lip Gloss or my Rimmel (London) Sweet Jelly Lip Gloss. I have green eyes with specks of brown in them. I don't wear eye liner but I am wondering if I should. My hair is chocolate brown. If it helps, I also wear glasses.

So do you have any suggestions for me? I don't know if I am applying my makeup correctly or not. I mean, I don't look like a clown or anything, but there are always ways to improve, right?

Oh, and I don't have the Bare Minerals Primer. My hair is a bit past my shoulders and it is super curly and I have bangs. I don't use liquid foundations because they look cake-y and kind of fake, but tell me if you know of a brand that doesn't do this.

Thanks!!!!!!
