Skinceuticals and many other companys suggest for you to use their B5 gel WITH their vitamin C.
the b5 gel is composed primarily of hyaluronic acid and b5...
if vitamin c degrades the efficacy of hyaluronic acid then why the heck would companies suggest for u to use it together?
it kind of reminds me of companies using retinoid type ingredient in their day cream...isnt that counter productive?? |

Welcome!  Most of the skincare industry is tailored around making a profit not making us beautiful. Many companies randomly combine ingredients that they know the public will lap up.
Secondly not sure what you mean about vitamin C degrading hyaluronic acid, do you mean the acidity of an L-ascorbic acid serum? There are other forms of vitamin C that don't require an extreme pH. Many people layer products with a wait period for absorption or use one serum morning and an incompatible one at night. There is an excellent thread on the implication of product pH here

AFAIK you can use a retinoid in the day providing you layer a high factor physical sunscreen over the top/ practice sun avoidance. |

Dr. Torodov from Smartskincare:
They do provide a single reference to a 20-year old benchtop experiment showing some degradation of sinovial hyaluronic acidby ascorbate. Whether this happens in the skin on topical vit C application is unclear, but even if it does, adding hyaluronic acid to the serum does not necessarily protect the endogenous hyaluronic acid in your dermal matrix. (And the exogenous HA does not integrate into your matrix anyway.)

Are there any newer studies?

Could you name those forms of vitamin C?
Are they possibly the mineral ascorbates? |

| I think Firefox is talking about AA2G and MAP. (Ascorbyl Glucoside and Magnesium Ascorbyl Phosphate.) They're not acidic like LAA. There is also "Tetra" C which is oil-soluble. |
