You need to exfoliate your legs at least once or twice a week. This will not only get rid of the build up of dead skin, it will also help prevent any ingrown hairs.
For the ultimate legs make sure you eat healthily and exercise to tone up and get rid of any wobbly bits.
Keep your legs moisturised by using a body lotion that is right for your skin type. If you like you can pick up a lotion with a little shimmer to give your legs a gorgeous sheen.
