  It makes the skin peel badly. That’s the reason why I start using it and give up very quickly. I understand it’s not tretinoin but it has some effect.

  @ngarayeva001, @chemicalmatt
  Thanks for information.
  What percentage of retinol did you use in the formula ? the documentation cited that it causes skin to dry. Can we use hydrating ingredients to offset the drying side effect of retinol?
  What differences of skin peel between retinol and glycolic acid?

  Thanks.

  Information from suppliers, Vitamin A, B3 need the final pH =6 or greater to prevent irritation.

   I use 3% of retinol in liposomes with a concentration of 3 million IU per gram. It causes moderate peeling which is normal.

  @ngarayeva001, 3% is too high for concentration of 3 million IU per gram. For my calculation, try it with 0.05 to 0.08% for no or lightly notice of skin peeling, no irritation with extra moisture. I prefer using Caprylic/Capric Triglyceride + your active moisture.
