What the gurus are saying

The formula's mix of tranexamic acid, niacinamide, and kojic acid earns praise for brightening and helping with dark spots, and it layers well without stinging, which gurus who work with sensitive skin or post-laser patients especially value. However, the actives sit at fairly low concentrations for the price, and experts split on whether it delivers enough: some find real results even without procedures, while others note that newer serums now target pigmentation more comprehensively at a fraction of the cost, and a small number report irritation despite the gentle profile.

"The one thing I like about this product is that it's nave safe. The first ingredient here is water, then butene glycol. These are basically solvents. The third ingredient here is niacinamide. So it's a healthy dose of niacinamide which is good. Sixth ingredient here is tranexamic acid. And then the ninth ingredient, so very very low percentage is kojic acid. I would just say these are very low percentage actives for skin of color. It's basically niacinamide plus tranexamic acid. But for $98, I expect a lot more than that. Honestly, there are many products out there, discoloration serums with niacinamide plus tranexamic acid at less than $10. So $98 is honestly marketing, branding, and paying people to do ads about this particular product. If you understand formulas, you just would never purchase this product."

THE ORDINARY VS LUXURY SERUMS
"SkinCeuticals Discoloration Defense, for 93 pounds I expect more than just niacinamide. There are no tyrosinase inhibitors in the SkinCeuticals product, and it's not really going to do much for your discoloration."

"This has tranexamic acid 1%, kojic acid and 5% niacinamide as well as their proprietary Heavies complex for brightening. I used to use this in clinic quite a bit after I performed a laser procedure like a Pico Shore laser or even a fraxel. I would then apply this to the patient's freshly lasered face to maximize the benefits of this brightening serum. I have found really good benefits with this both with and without laser treatments, but it can be very useful as an additional step after laser to really help to brighten up those dark spots. I also find that this doesn't sting at all, so this is really great for sensitive skin. This is something that layers really well too. I find that this layers really well under moisturizers and under makeup."

"I personally get very irritated from this product. I always get like irritation redness and even sometimes acne like lesions. It's a low pH so I don't know what the issue is it's causing this."

Best And Worst Of Skinceuticals
"This is a great serum, I'm not saying it's not, but it has aged a bit. I used to recommend this quite a bit when I first started residency. It is pricey, over $100 for a dark spot corrective serum. Now we have products that target all of the steps in comprehensive ways of preventing pigment production, preventing the transfer, and removing and exfoliating the existing pigment. There are things that exist now that have comparable or better results at a much lower price point than this one."
~Approved
"This also contains a serum called Discoloration Defense which helps combat irregular pigment in the skin. Both the vitamin C topical in the Florentin CF and the Discoloration Defense are working to brighten the overall complexion. These are both really thin liquidy serums and they layer very well with one another."
