How to use
General guidance from this product's category and active ingredients — always follow the directions on the package.
Trust & honesty
The concentrations these actives are typically effective at in research — not a measurement of this product.
L-ascorbic acid is usually used at 5–20% (around 10–15% is common). Above ~20% adds little and tends to irritate more; it also needs a low pH to work.
Ascorbic Acid (Vitamin C)
INCI lists don't disclose amounts, and we don't claim to know this product's levels — these are the ranges these ingredients are usually effective at, so you can tell a real formula from "fairy-dusting" a marketed active. How we estimate this.

There are two new ingerdients which are fugal acne trigger. So now I do understand why I break out ...
I purchased this product in high hopes after reading rave reviews online. To my disappointment the product fails to deliver after 45 days of continuous use. I keep this serum in the fridge since Vitamin C has a tendency to get spoiled in warm temperature. Actually what I find strange is the color of serum. It's already yellowish brown when out of the bottle instead of transparent. Perhaps Drunk elephant being clever to not let consumer know if the product is spoiled or not. The serum gives a ...
please be careful with vitamin c, it gave me acne in the 2nd month of using it and chemically burned my skin, look up the risks of using pure vitamin c from a non biased dermatologist source. from what I've learned when vitamin c is oxidized it can damage the skin and this product one hundred percent damaged my skin. the first month of using it was bliss but after that everything went downhill overnight 1 of 2 1 of 2 Community Collections with "Drunk Elephant C-Firma Day Serum" Liah Yoo Skinc...
