In their words
“I’ve been using the Murad Vita-C serum and really like how lightweight it feels on my skin. It absorbs quickly, doesn’t leave any sticky residue, and gives my face a nice healthy glow. After a few weeks, I noticed my skin tone looking brighter and more even.

“I didn’t mind this product. I actually got it on sale at Sephora for half the price. But I would never repurchase this again. I feel like a lot of other products can do the same thing for far cheaper. This made my skin soft and gave a nice dewy look. The packaging was horrible. I don’t know if it dispensed the products in the tubes evenly.. there still some product but won’t come out”
