Before I used this product, I had really dark pigmentation on my skin which was the aftermath of acne. Using this product not only helped lighten those darker areas, but it also helped reduce the size of the active acne that was left on my face. It kind of stings a little when you get it on open skin, but it’s bearable. After awhile, you won’t feel it anymore. My skin was brighter and healthier looking while using this product. The one thing I don’t like about it is the packaging, which really isn’t that big of a deal. The thing you use to suck up the product is too short, so it’s really hard to get the rest of the product at the end of the bottle. I had to dump some of it out onto my hand, which made me use a bit more than I needed, but as I said before it’s not that big of a deal. I would definitely recommend this to anyone who struggles with dark marks and hyperpigmentation. Repurchasing.
