Talk about a crazy tip that gives such satisfying results! Natural beauty expert Renée Loux tested this hack and revealed that the treatment can be moderately effective. The trick to reducing the appearance of cellulite is in the recipe. To achieve results:

Mix 1/4 cup ground coffee with 3 tablespoons hot water. Allow the mixture to sit for 10 minutes to absorb the water and form a paste.

Next, mix in 2 tablespoons of olive oil to help bind the grinds.

Rinse with warm water to remove all grounds, then pat dry and moisturize if desired.
