  On extracts and how effective they are

  Posted by Majman on October 13, 2018 at 5:13 pm

  I’ve read severally here that extracts aren’t effective at doing much  including Hyaluronic acid, so was wondering if anyone has had experience with centella asiatica and pine bark extract and if they are effective at doing what they claim they do and if stable

  I use both. But honestly, who can say if they are effective? I use pine bark extract in place of dried tea (EGCG) extract because the tea extract is unstable and even in darkness, at 3 deg. C, degrades too rapidly.
  NOTE:
  I *assume* that the tea extract degrades, for one reason only. (I am not sure if my reason is valid but I think it is.) The reason is, that after storage for about three months in ideal conditions, the tea extract loses its indicator activity and fails to change colour as the pH changes.

  Yeah @chemicalmatt by including Hyaluronic, I was mentioning it as on its own and not as an extract

  I’m sure Hyaluronic acid will give some humectant effect.  But extracts pretty much don’t do anything noticeable in most cosmetics.
