Using banana in your daily skincare regimen will improve the overall softness and elasticity of your skin. Bananas are full of vitamins, minerals, and antioxidants, which can protect and moisturize skin. They can be used to treat dry cracked heels and itchy skin. Mashed up and combined with honey, banana facial or hair masks are especially popular in India. Additionally, the potassium in bananas calm puffy eyes when applied directly on the skin.
