Tomlinson's top tanning tip is applying Vaseline around her hairline to prevent an obvious darker tan line developing along the top of her forehead. To avoid a dark line along her jaw, she recommends blending the fake-tan formula right to your ears, down your neck, and even around and down the back of your neck. Alternatively, after applying tan to her face, she likes to use a dry makeup brush to gently buff the fake-tan formula into her hairline and along any other edges.
