[Routine Help] Too much Vitamin C?

Beauty Tips For Body Care
Hey! I'm creating a skincare routine and was considering adding two products, Drunk Elephant's C-Firma Fresh Day Serum and Dr. Loretta's Intense Brightening Cream. They both contain large concentrations of vitamin c. The Drunk Elephant serum has 15% L-Ascorbic Acid, 0.5% ferulic acid, and 1% vitamin e. The Brightening Cream has 20% l-ascorbic acid. I'm wondering if using both of these products(the drunk elephant serum once per day in the morning and the brightening cream 2x a day) would be too much vitamin c.I'm asking because I remember people saying that their skin got irritated or something with too much vitamin c. Also, a lot of potent vitamin c products suggest using infrequently, and then building up to constant use, implying that there's a potential for irritation.Would it be okay to use both of these products like I've mentioned? Any other product suggestions are appreciated.
