What owners single out
Buyers' weakest aspect—product stability and oxidation—directly mirrors video reviewers' concerns about the formula's sensitivity to light and temperature, with multiple owners receiving yellowed or brown-colored product
In their words
“Gals... this is my go-to for 3 years and my skin looks better at 35 than it did at 25. Expert tip for ya: cover it in tin foil and leave it in fridge. It will slow down oxidation and keep the C active much longer than at room temp (you’ll see it turn yellow/smell bad as it oxidizes). Highly recommend!”

“I love skin ceutical products, but this is awful!! I have used their other vitamin C serums in the past with no problem but this serum causes not only a rash but a complete allergic reaction. I had to actually go to the doctor where they said it looked like I had been stung by a bee because my face was so swollen. I had to be put on oral steroids! This product should not be on the market. Very dan”
