  TEWL and corneometry results

  Posted by pma on March 17, 2024 at 9:53 am

  My first serum, although lightweight, showed a -17% change in TEWL (D30) and +38% for corneometry. According to what I’m reading, it’s a great result, specially for a very lightweight product.

  I guess results can vary due number of volunataries, how it was made etc., but I’m curious about what results are you getting for TEWL and corneometry with moisturizers.

  We test very few as it is not often requested by our clients. The most recent was -19% and +36%.

  They were performed by a third-party claims substantion testing provider.
