Homemade scrubs and packs are not only an effective but also a pocket friendly and convenient way to beautify the skin on your back. You can use things that you find in your kitchen. Mix some sea salt with baking soda and use this as a scrub on your back to soften the skin. For smoother skin, mix oatmeal powder with some lemon juice and cream. Gently run this paste on your back and leave it on for 10-15 minutes before washing it off.
