How can i gain a healthy looking skin without using cosmetic products? what are the natural alternatives? :)

Sleep and water: Sleep at least 7 hrs per night drink lots of water avoid direct sunlight.

Healthy diet ;...: You are what you eat, so eating healthy (eat lots of fruits ; veggies ; healthy oils like flax or hemp and avoid fried foods, sugar, non-organic meats ; gmo's) is the first step. Some find avoiding dairy helps. A good multivitamin may help, perhaps extra zinc, and 5000 iu of vit d in fall ; winter.
