  pH options for (Face) cream with Niacinamide. — Cosmetic Science Talk (chemistscorner.com)

  There is a search bar on the top right corner…. Type ‘Niacinamide’ and hit ‘GO’.

  My mistake…I meant to say PC grade rather than PH. I just wanted to know if pharmaceutical grade (for anything, really) is worth the extra money.

  My chemist said….Nope.  So I use the cheaper one at 2%…at a pH around 4.7-4.8…and no issues.
