Moisturizer Answers

I think I’ve cried all the water out of my body..I feel so UGLY. This is the last time I’m gonna ask this question, no one answers anyways.. I need to make some lifestyle changes..I’m determined now to be pretty.
I’m gonna start eating a healthy diet, drinking a lot of water, & exercising. What else could help clear my acne (face, neck, chest, & back) along with these changes? I also am going to take a multivitamin. I have oily, sensitive skin & I VERY easily get the marks leftover by acne even when I don’t pick at them(so I have lots of red marks). I wash with Cetaphil gentle skin moisturizer(my face dries out easily), & use Cetaphil lotion in the BIG bottle with the pump thingy. I use Queen Helenes mint julep masque on Sundays & Wednesdays & exfoliate 3 times a week with baking soda. Give me your BEST acne advice.
Please ans thanks.
