What the gurus are saying

Tranexamic acid and niacinamide at a drugstore-friendly price is the detail that keeps coming up. The takes lean warm, calling it gentle and a fine pick for evening routines, though the cautious side was not overly impressed with how it performed over time. That same side calls it a good starter for dark spots, but points to more comprehensive options, and a dissenting take says niacinamide did not agree with their skin.

Best & Worst Dark Mark Serums
"Good Molecules Discoloration Serum, 2% tranexamic acid, 4% niacinamide. That is an absolute bargain. [...] That is definitely the one to start with. [...] I would probably start with the Good Molecules discoloration serum and see how you get on with that one first because that is just by far the best buy."

"This is $47, so actually quite reasonable. [...] The third ingredient is glycerin, and it comes out a bit milky. The fourth ingredient is niacinamide, then they put in Calcium Tranexamate Melate, which is a derivative of tranexamic acid. It is a naif safe product and it's a good first line, however it is a little bit expensive for what's in here. In fact, you can buy your tranexamic acid plus niacinamide from The Inkey List for a fraction of the price."

"But I wasn't overly impressed. Even though it's a good combination of ingredients, I wasn't overly impressed with the performance over time with this product, even though it is a good starter product for dark spots. [...] If you haven't tried any dark spot product and you're looking to start a dark spot product, I think this is a good starter product. But I think there are better, more comprehensive solutions that are currently out there."

"I still absolutely love it. It has some tranexamic acid derivative which is really gentle alongside some other brightening agents. [...] You kind of have to invest in this product, you get long-term payoff but maybe you're not going to get those quick wins, so if you're impatient these might not be for you. But honestly, if you've got sensitive skin this won't irritate it at all and you'll get some really great results in the long term."

"This is from Good Molecules, they're made here in San Francisco. It's so inexpensive, just $15. This is actually a new active for you to try in your routine: tranexamic acid, or TXA, which is actually used in emergency medicine if someone comes in with a gunshot wound or major hemorrhaging, they get tranexamic acid, but it actually works as a discoloration corrector as well. The packaging is really nice, so pretty. It's inexpensive but so effective."

What The Industry Won’t Tell You About Product Recalls & Reformulations
"The new formula [...] goes on smoother and absorbs better. It's [...] much more milky and creamy and pearlescent, and it soaks into the skin and absorbs better than the old [...] one. It goes in almost immediately and dries down without any tacky or greasy feeling. The new formula works a little bit faster than the old one, and those who have used it love it a lot better. I appreciated that they were able to find ways to make it better and to make the packaging less environmentally taxing."

"This has tetraceutic TX vector which is a form of tranexamic acid that is supposed to penetrate deeper into the skin. It also has niacinamide which stops pigmentation from spreading. [...] Niacinamide doesn't stop your skin from actually creating pigment, it allows it to be created and then it just says no, you stay right here and don't spread to the keratinocytes over there. [...] This is such a great serum especially if you struggle with hyperpigmentation and acne."

"What I also love about this is that it contains niacinamide. For evening, this is a fantastic formula if you want something that is gentle on the skin and non-offensive. There aren't any majorly harsh actives in here that could cause the skin to do a 180, and you're looking for something that has those benefits in a nice night serum. This is an inexpensive and affordable but effective option."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.
