Ok so I've come across plenty of lists of items that are declared to be "pore clogging." A lot of these items are found in just about every single soap and shampoo in existance and they are VERY hard to avoid.
Examples: sodium lauryl sulfate and sodium laureth sulfate
These items are given high pore-clogging scores. So this brings up the question of, how do people know they are "pore clogging?" Is there a test you can do? I read somewhere (and I can't find it again) that there is some type of test that is done under a microscope; perhaps someone knows more about this?
If there is a scientific test that can be done under a microscope which proves that certain things clog up pores, where can I read more about this?
Thanks guys.
My understanding is that these ratings are based on experiments on the inside of rabbits ears, which apparently closely approximates human skin. However, there is a lot of individual variation and the use of the phrase 'non-comeogenic ' is completely unregulated.
Your right though, avoiding these ingredients usually means avoiding 99% of the products out there, it can be very difficult to find good stuff
