00:00Putting retinol and vitamin C products at the same time is a big no. She's wrong. This is a
00:05misconception. People thought, and this is where you can probably have like a little math thing
00:09going on, that retinol changes the pH of your skin and vitamin C is an extremely acidic pH and
00:13therefore if you have one over another, you're going to deactivate the retinol, but that's not
00:17the case because your skin is actually very acidic when it comes to pH. And so it's actually been
00:22proven that when you use both of them in conjunction, they actually increase their
00:26efficacy. And so if your skin can tolerate it, if you're somebody who does not have extremely
00:31sensitive skin, if you're not prone to irritations, and if you've already been using a retinol and your
00:36skin is used to it, then by all means try layering on the vitamin C because you'll have a better
00:41effect
00:41overall.
