There is no difference except bottle size. The 2oz is our travel size and the only size that has the Lavender scent. Both the 8.5 oz and 2 oz contain the same ingredients. Both sizes are face-quality moisturizer and can be used on other parts of the body. The formula was created as a high-quality face lotion; however, we believe all your skin (your largest organ) deserves only the finest and most rejuvenating and nourishing ingredients.
