How to get smooth and clear skin?

this summer i decided to excise and eat healthier to get better skin and body. My sister told me about papaya soap that can even out skin tone but you have to buy it online and my parents wont do that. So i wanted to know if anyone knows of something that can even out skin tone to make it smooth and clear and maybe a little lighter that i can buy at a store? PLEASE AND THANK YOu
