  Brightening serum changed color

  Posted by ngarayeva001 on August 6, 2018 at 9:23 pm

  Hello everybody! A brightening serum I made changed color to orange. I believe it happened after I added N-Acetyl Glucosamine. I used to make the same formula without NAG and it didn’t change color. The texture and feel did not change. May I ask you to comment on whether the change of color signalises about a problem or it is safe to use? Thank you in advance.

  Original formula:

  Aqua - 78%

  Vitamin C (magnesium ascorbyl phosphate) - 2%

  Alpha-Arbutin - 2%

  N-Acetyl Glucosamine - 3%

  Hyaluronic Acid SLMW - 0.5%

  Niacinamide - 6%

  Hyaluronic acid HML - 0.5%

  Allantoin - 0.5%

  Propanediol 1,3 - 5%

  T-Resveratrol Fluid (by makingcosmetics) - 1%

  Dimethyl Isosorbide - 0.5%

  Paraben DU (by makingcosmetics) - 0.5%

  pH of the formula is 6.
