What owners single out
Buyers' weakest aspect—skin sensitivity—aligns with potential irritation concerns that video reviewers may have flagged about the formula's active ingredients.
In their words
“I’ve been using this serum consistently for about five years now. I am pleased and surprised that I frequently receive compliments on my complexion— and I’m 78 years old. A bottle lasts almost a year if applied once daily, so I consider it a bargain. I’ve started using Ole’s lip treatment each night and can see it’s working, too.”

“Used one time by its self and had allergic reaction. Caused red welts on my neck and red patches on my face that lasted for hours, even after the product was washed off. It was painful. I don’t use any retinol or anything with major active ingredients that would cause this reaction. I’ve used plenty of other Vitamin C serums without issue.”
