Not sure about this product. When it arrived it already had a yellow tint and it quickly turned brown which means it is less effective. Like other vitamin C products it has a short shelf life and needs to be well kept in the fridge between uses.
I got this because it was a Vitamin C Serum, and it works very well on me. I have no irritations, my skin looks healthier and glowing and its easy to use.
I was really looking forward to trying this serum and it disappointed me so much by leaving my skin so sticky and it didn't even brighten the skin .don't waste your money.
It has a very sticky feel to it. But it sinks to the skin after some time. It helped me with my post acne hyperpigmentation. The only Vit c that didnt break me out. ♥️
