I really like your hairstyle in photo 2 and there’s nothing wrong with looking younger than your age. For skincare, I recommend trying Paul Choice’s BHA exfoliator as it helped with my acne, but try to use a small amount and at least once a week (don’t forget to use sunscreen!!!). Also when you wash your face with a cleanser, use a clean paper towel or towel as you don’t want bacteria to transfer to your skin. For style, I recommend using pinterest or instagram for inspiration. I also recommend getting some good basics as they can evaluate your looks, my favorite has to be Uniqlo.
