  PENETRATION RATE OF THE SKIN WITH COSMETICS..

  Posted by SnT Lab on October 12, 2015 at 1:29 am

  Hello There,

  We, Science & Technology Laboratory Co., Ltd are the importer and distributor of skin measuring machine in Korea.

  And, we are very interested in measuring of the absorption and penetration rate of the skin with cosmetics.

  While we are searching newly invented measuring machine for this task, the absorption and penetration rate, we have found this site. So, if anyone can give us some information, please send us the information of the measuring machine for this task. We think you know what machine is suitable for the measurement of this task or you have used for your article.

  Please let us get good information for Korean cosmetics and raw material manufacturers.

  Thank you and Sincerely,

  Best Regards,

      Kang-Duck, Ha

  Sales Manager, SnT(Science& Technology) Lab Co., Ltd.

  I’m sorry, but I don’t understand your question. Please rephrase.

  I mean the measuring machine to measure the absorbed amount or the infiltrated amount into the skin after applying the cosmetics.

  There is no general “machine” that can measure skin penetration rate. 

  You have to:

  1. Decide which compound(s) you want to measure

  2. Develop a method - or find one in the scientific literature

  3. Buy the necessary analytical equipment

  Which machine you need depends on which substance/s you want to measure and the method you want to use (and your budget).

  The only way I know of to accurately measure   “the absorbed amount or the infiltrated amount into the skin after applying the cosmetics.” is to physically remove skin layers using the tape stripping method (http://www.ncbi.nlm.nih.gov/pubmed/18775778), and then to chemically analyze each layer removed. As you might imagine, finding a volunteer to have a patch of skin removed a layer at a time with adhesive tape isn’t easy.

  
  

  I am unaware of any machine or method that would do this in any other way, and I imagine that such a machine, if developed, would cost many hundreds of thousands of dollars – which would render it useless for all but the wealthiest companies.

  I think something people don’t realize is just how unsophisticated the field of cosmetic testing is. It would be great if there were a “skin ingredient penetration” machine but we have a hard enough time quantifying the level of moisturization an ingredient might provide.  Cosmetic product testing remains complicated and not very good in my opinion.
