Get it Together

There are so many acne treatments out there but it seems like there are only a few that are marketed as an adult acne treatment. I don't understand how a teen and an adult are supposed to use the same thing when their skin and hormones are so different. It really just doesn't make a lot of sense to me and I wish there were more that specified. It's kind of like the companies that use fragrances in their products, don't they know that this irritates this type of skin to being with?
