I have struggled with cellulite since I hit puberty. I was always quite thin, and would have been considered underweight, and yet cellulite still plagued me. I never tried to do anything about it until I got a bit older, gained a little more padding, and watched the tone and appearance of my skin change. This product does not do anything for cellulite. It does however tighten the surface of the skin a miniscule amount. It applies like a serum. It did not work for me.
