In reply to Katie.

So glad to hear it!

If you want to try both, I’d start slow – probably with just one and then add the other one in later. I should include that both vitamin C and retinoids can cause irritation at first. If you use both, best to use the retinol serum at night and vitamin C in morning since the vitamin C protects from the effects of the sun whereas vitamin A makes you more sensitive.
