The following list is only the ones I have personally used and tweaked to what has worked for me, you may use it as is, or change it to your needs.
This Exfoliator will leave your skin absolutely soft! I swear that you will love the results! Also, coffee has been known for being able to get rid of cellulite by slowly smoothing those pesky dimples. The coconut oil helps moisturize your skin so the combination with the coffee is an excellent one for coffee also tends to dry out the skin. Spirulina is made of algae or seaweed, which has been known to be used in products that help improve skin texture and even help tightening loose skin. So as you can see, there is not one reason why you wouldn't want to try out this concoction.
To Use: Mix half a cup of ground coffee (better if it's organic), 2 tbsps of spirulina and enough coconut oil to make a thick paste (About 4 or 5 tbsps) You want to take a warm shower of bath and start applying this paste to your legs, tights, navel, and arms. Work the mixture in a circular motion. Take your time doing this, the longer you do it, the softer the results. Please be extremely careful when doing this as you may slip and fall due to the coconut oil making your bathtub slippery.
2. Brown sugar, coconut oil (or almond, jojoba and olive oil)
To Use: Mix about half a cup of brown sugar with 3 or 4 tbsps of oil. Rub the paste-like mixture wherever you want to remove skin roughness. Work slow and get to all the spaces for better results.
3. Epsom salts and coconut oil (or your preferred oil)
To use: Mix about a cup of Epsom salts with 2 or 3 tbsps of your oil of choice, though I have only tried it with coconut oil which is my favorite. Rub your feet and legs with the mixture while taking a bath or shower and feel the results almost immediately. I only recommend using this on the feet and legs since these salts tend to be rough in any other parts of the skin. You may also add them to your bath water for a more relaxing effect.

4. Oatmeal, sugar and water.
To Use: Grab a 1/4 cup of oatmeal, a 1/4 cup water, and 2 teaspoons of sugar. Throw the oatmeal in a blender or coffee grinder until smooth. Next, add the water and sugar and scrub those dead skin cells away. You can also add a few drops or oil to make it slide on a little easier if you wish.
5. Lemon and sugar
To Use: Squeeze the juice out of one lemon into a small container and add 1 or 2 tbsp of sugar. Mix both ingredients until smooth. On a freshly washed face, gently begin scrubbing the paste all over your face avoiding eye area. Leave on for 5 to 10 minutes and rinse away.
