The barrier weakens with age and the more pale your skin is the thinner the barrier, which means you’re more prone to irritation. The good news is since your cells are constantly renewing themselves, you can improve the issue and prevent future damage.

The comedogenic scale was originally created to rate the tendency of a skincare ingredient to clog pores. The idea of comedogenic products and their effect on the skin was first introduced in 1970s by Albert Klingman and James Fulton and was based originally on tests conducted on rabbit ears. There are plenty of products that like to boast a low comedogenic rating and even professional skincare companies that educate estheticians on how to spot so-called comedogenic ingredients, however, I find this concept outdated and unreliable for many reasons.
