Retinol is known for its unique properties that stimulate skin tissues to create thicker skin, which can cover the lumps and bumps of cellulite. A study on the application of 0.3% retinol cream to the area for six months showed improved appearance of cellulite. The application of Retinol is one of the easiest and non-invasive beauty tips to hide the lumpy, fat deposits that commonly appear on the abdomen, thighs, backside and upper arms.
