  Why use “ppm” unit measurement on skincare product labels?

  Posted by raiyana on May 19, 2020 at 2:23 am

  There are cosmetic brands like The Ordinary, Paula’s Choice expose active ingredients % on product labels.

  But recently, i see a lot of cosmetic brands (especially korean brands) like to expose their active ingredients on the labels, but in ppm unit measurement.

  For example:
  10,000 ppm snail mucin
  50,000 ppm rice water

  Just wanna know, from a chemist or formulator’s perspectives, what’s the advantage of using ppm instead of % on product labels? Why this trend? I personally think this ppm trend is confusing. Why cant brands just stick with %?

  Just divide by 10,000. At a guess, it sounds biGGER.

  Thanks @Belassi. Yes, i do agree 10,000ppm sounds bigger than 1% when in fact both are the same amount.
