They are always coming up with new uses for old treatments. For example, Retin-A has always been used for acne. It sheds away dead skin cells, promotes the growth of new cells, and over time it produces a glow to the skin and otherwise. Now the side effects you suffer in the meantime are not pleasant even though thickening your skin among other things is definitely a good thing. That being said, Retin-A has been recently introduced to actually get rid of two other problems: cellulite and fine lines. Yes, I stress fine lines. It does not actually reduce deep wrinkles. But the theory behind it is that when it thickens skin and strengthens it, it obviously applies to these areas. It has been shown in some studies to help you in certain minor ways. The side effects should not be ignored, and it won’t work for everybody. But frankly speaking, it’s not a particularly bad idea. And frankly speaking, I wouldn’t mind using it for the right purposes. If it’s useful, why not right. But this being said, I would actually suggest using something else if you have more serious cases of cellulite or wrinkles for that matter. Its uses are seriously limited to some degree, and quite frankly, you could easily find something else that would be more effective in certain other ways, though cellulite is debatable.
