We all know never to mix (or layer) Vitamin C and Copper Peptides.
What are some other mixing no-no's?
Is it ok to mix Retin-A with Vitamin C?
Is it ok to mix Retin-A with AHA? |

| I wouldn't mix retin-a with AHAs, or any other acid for that matter, you'll end up with a mess of inflamed skin. |

| How do Retin-A and the AHA's neutralize each other? |

I'm not sure what the process is but my skin specialist (and she has 32 years experience and has a Health Science degree) has told me that glycolic acid/AHA's inactivate Retin-A - probably a bit like Benzoyl Peroxide inactivating Retin-A.
Before I knew about this reaction I had previously used glycolic and Retin-A together and it left my skin an inflammed irritated mess - that's just my experience, so I'm not sure if it is this irritation that is the result of the inactivation of the Retin-a.
I'm sure there is someone who has a scientific answer for it on EDS |

I am using Glycolic and Retin-A together woops, thank you for the info. If I still wanted to use both actives though what would be a good method of doing it? |

She might have meant the other ingredients in a Glycolic/AHA product can inactivate RA.
Glycolic acid can actually enhance penetration (and cause increased irritation).

Well I'm going to postpone changing until theres more information on the subject then 
How does the glycolic help the Rentin-A penetrate better? |

Per the article that circus linked to:
"CONCLUSION:
These observations indicate that the addition of an AHA such as GA to a retinoid such as RAL results in a better bioavailability of the retinoid, thus a higher delivery of RA, which potentiates the biological activities of the retinoid. This combination allows a delivery of high amounts of RA in the skin while preventing the side-effects usually observed with high concentrations of topical RA." |

Thanks for that, I have to admit not looking at that just reading the rest of the quote, I guess a good Retinol product should also include the Glycolic for a stronger formula.  |

The Avene Triacneal is based on Retinaldehyde and Glycolic if you'd like to try. This is the improved version replacing Diacneal. |

| I do not mix Retin A with anything, I use it at night and only use Emu oil after application to hydrate and minimize irritation, but I use Vic C in the morning then. the upper layer (dead skin) rolls off easier and the new layer is healthy then. |
