I read some article to clean the darkness elbow and one of the remedies is good to try and share to you all I must say. As these two ingredients are easy to get them from a bakery home.
MILK + Baking Soda
Just use a spoonful of milk and add 3 tsp of baking soda
Mix them like a paste
Apply on your face (chin and mouth area) and the body before taking a shower
Very low cost and effective!!
Plus moisturizing your skin!!
