The Vitamin C23 Serum

product review positives

Doesn't tingle at all! Spreads easily, doesn't leave a layer of film even if it contains oils. Makes my skin feel soft upon application. I'll need to use it for a longer time (4 weeks) to see how it fades my acne scars. The bottle is really cool too....

product review negatives

Smells like ham but it fades quickly. Contains alcohol denat which can be drying or irritating for some. Stains light colored fabrics, same as any other vitamin C product. Oxidizes in 2 months so you have to use it fast.

The Vitamin C23 Serum

product review positives

This highly concentrated pure vitamin C formula is contained in a specialized bottle that allows it to expel gas whilst blocking the inward flow of oxygen. There's a small popping sound and a whiff of corned beef scent once opened, which kinda surpri...

product review negatives

It needs to be stored in fridge once open and it only has 2-month PAO. There's mild stinging sensation on my cheeks though it only last for a few seconds. It also smells like corned beef.

The Vitamin C23 Serum

product review positives

Even though, it is a high concentrated serum, it definitely accurate, it doesn’t sting on the face I like to use it after the essence step

product review negatives

PUT IT IN THE FRIDGE. So according to the instructions on the packaging it says to put it in the fridge, some people may not read the this so I’m making you aware of it.
