As a wrapping material use regular food film, which you can buy in any superstore (e.g. Asda, Morrisons, Tesco, Sainsbury), which cost no more than 2.00£.
Then for mask use black clay (you can find them in Superdrug, Boots, Wilkinson, online)- either alone or in combination with ground cinnamon or cinnamon cream that sold in the store. Mix clay with water, then add one to two tablespoons of cinnamon. You can also add some essential oil. In this case, best would be to use oil on tangerine or orange base, (few drops – 2-5) as well as a few drops of freshly squeezed lemon juice. Apply this mixture on your problematic zones and wrap everything tight and keep it for 40- 60 min. Then take a shower and use some body moisturiser ( I use SeaSource Renewing Body Gelée from Arbonne – this cooling gel nourishes, hydrates and moisturises, helps to maintain skin's natural surface ionic balance I love it! ask me if you are interested in this product)
You can try other body wrap – using coffee grounds (use thicknesses from your morning coffee) and honey, adding a little bit of ground black pepper.
Please note that the following methods have been tried already, but it does not mean that it is suitable for all - you can feel the tickling sensation in the skin, you also can get allergic reaction from some of the ingredients, so be careful before use this method.
