I received this as a sample with a purchase. I don't use a lot of brightening serums but I do have melasma so I'm a good contender. I really enjoyed this serum and was even flipping the bottle over at the end to hopefully get more out the next days. I used it every night consistently and I could definitely tell a difference in my face pigmentation. My melasma was still present but I did feel that it faded perhaps about half, which made me very happy. The other good thing is that a little does go a long way with this product. It does have a sweet perfume-y scent. This didn't bother me too much but I do prefer unscented products. Overall, I really really liked the visible difference this serum made on my face. If it wasn't so expensive, I would definitely add it to my routine.

Product was okay- I received this as a gwp purchase. It was kind of tingly on the skin, probably from the actives in it. As far as results- the payoff wasn't amazing and I wasn't crazy about the ingredient lineup. While it felt and smelled good, I think there are better products out there.

This serum brightened my skin discolorations & my skin tone. The texture of my face has softened. I love this product and will continue to use it.

It is a lightweight product that does not cause breakouts. However, it causes skin to feel dry and did not brighten or even skin tone.

I received this as a large sample and have been using over a few weeks. I only use it in the morning every other day. I use a different, highly recommended and rated vitamin C serum on the opposite day. This product is ok. I have not noticed any major changes to my skin and that is likely because I have already been using a vitamin D serum. It smells like perfume, which I do not like, but the smell goes away quickly. It absorbs nicely and goes fine under makeup. I have not had issues with breakouts from it. I would not switch from my regular vitamin C to this one. There is just nothing spectacular about it, but it does come at a better price point than other vitamin C serums.

One of my favorite products, makes my skin noticeably smooth. Product helped the tone within the first few days.

To be fair I only had a sample of this product so maybe if I used it longer I'd notice something. But I really don't see the benefit of it. I didn't notice a change in the discoloration of my skin which I was hoping for. I have tried numerous expensive products but not many seem to live up to the hype.f

This serum did absolutely nothing for my skin or my dark spots, I don't recommend it to anyone.

I have old acne scarring and redness on my cheeks, which I've tried for years to cover up with every kind of foundation and concealer. It all just gets cakey no matter what! I finally decided to listen to my Instagram hero, Alex Steinherr, and ditched the harsh retinols and started using a simple routine of Advanced Night Repair, this brightening serum. The difference has been mind boggling. It's such a good combination! And I cannot ever live without this brightening serum again. I find that after two weeks, I need less and less makeup to cover my redness and scarring. It's all just beautifully fading away. I am obsessed with Estee Lauder skincare. It works!

I received this as a sample from Dermstore and have been using it for a few days. The good news is that it did not cause any breakouts (I am sometimes prone to acne.) It also did seem to work for brightening. I used it at night and did notice a bit of improvement to my skin tone and old acne scars! So those things are all good. The slight downside it that it was a bit drying. I noticed that I needed to use more moisturizer than normal when incorporating this product into my routine. I would probably stick with a different brightening serum that is less drying after this sample runs out, but there were several things that I liked.
