As long as you follow the instructions carefully and prep your skin adequately, self-tanning lotions work a treat to give you a safe, sunless golden glow. Generally, you need to start with well-exfoliated skin that's clean and dry. Some brands recommended adding a small amount of oil-free moisturizer to areas like the ankles, knees, and elbows, which are notorious for being try and going patchy. The best, streak-free results come from using a specialized applicator mitt, which will help with even coverage. Leave the product on for the specified time, and avoid sweating, getting caught in the rain, and applying other products while the color is developing.
