I have used other kahina products and really like them. I have some melasma and I am hopeful that this non-toxic product works. I seem to notice some improvement but I think it just takes longer.

This brightening serum actually works! I was looking to fade some post-acne marks on my cheeks and in the past few days I have noticed this crazy luminosity to my cheeks. I always have a few breakouts here and there and I cannot say that they have gotten any better or worse while using this serum. It definitely has not caused more for me. If you are on the fence, I would say to give this a shot!

I bought this after hearing glowing reviews from favorite natural beauty bloggers, since I'm looking to find clean brightening and anti-aging products to replace my dirty ones (those products are my last dirty holdouts since I've found natural replacements for everything else). I definitely did not expect that this would be an overnight miracle, but even still, I was disappointed. After just over four weeks of nightly use, I saw zero improvement on light freckles or general brightness. I'm 30, fair, and have been using SPF religiously for the past 12 years, so I wasn't looking to turn around a dire situation. Worse yet, this triggered breakouts during my period which I'd stopped getting years ago. When I stopped using it and went back to my old regimen, they went away quickly and haven't returned. If the product were a better match for me, I wouldn't balk at the price but as is it's to expensive for the results. Too bad. I'm still on my search for clean anti-agers/brighteners!

Too early to comment on it's brightening effects,but it does leave my skin soft and smooth...

I received a sample of this when I ordered Kahina's argan oil about a month ago. I started using it every night, and as soon as I used up the sample bought a full size bottle. So far, I love it! I've already noticed a difference in my skin tone, less redness, and more even. I'm hoping that it works to help fade some old acne scars, but it is too early to tell for that.

I got a sample of this as soon as it was available, as I love this entire skincare line. The one product my skin was not fond of was the other serum (a bit too heavy for my combo skin) so I was eager to try this; this worked better for my skin, and the results were visible. As I had a sample (which lasted several days), I can't say how this works long-term, but I will order this product with my next SBL order.

This line of skin care is truly outstanding. It works quickly to improve your skin overnight. Redness, dry patches, blemishes and scars all diminish. The Brightening Serum is an awesome product! You can use such a small amount of these products and they last for months. The best there is and my skin could not be happier! :)

I've been using this serum for a few days and while I cannot speak to its long-term brightening effects I feel that it will do the job of evening out discoloration for me. I love how it glides on and works with my skin. It's got good vibes. Been using it a.m. and p.m. Will def. stock up on this one. Thanks Kahina for providing a natural brightening product!
