What the gurus are saying

This serum combines 2% alpha arbutin (which blocks pigment production), high-concentration tranexamic acid, peptides to fade spots, licorice, and algal extracts in a formula balanced for strength and gentleness. Reviewers found it delivers results in about a month and works best for advanced hyperpigmentation users, not beginners; some described it as sensitive-skin friendly. One sample oxidized and turned black before expiry, so proper storage and a pre-use check are important.

"This one also has obviously tranexamic acid. It's got vitamin E. It has licorice root and then it also has reishi mushroom. It is on the more expensive side of things. This is just one of my empties that I finished, but I really liked and enjoyed it."

August Skincare & Beauty Product Empties - Winners & Losers for the Month!
"I really love this, the manufacturing or the expiration date is May 2025, but it went bad a little early, so it's kind of bummed. That doesn't look like something you want to put on your skin. I've had good luck with their mandelic Dark Spot Corrector though, but this one, I don't know, kind of a bummer. Generally when it's black it's not a good thing. Generally when a skincare product turns black or like dark orange or something like that, it's generally not the greatest sign."

"This is the Tranexamic Acid & Arbutin Advanced Brightening Serum by Allies of Skin. It has a 2% alpha, which you need for this hack, but it's packed full of other brightening ingredients. This definitely isn't for beginners. I'd say this is for more advanced hyperpigmentation skincare aficionados. If that's you and you've been on your hyperpigmentation journey for some time, this could be a really good option to use. You can still put a couple of drops of this into your moisturizer or just use it as a standard serum. But this gets you your alpha boost alongside so much else and this will work in about a month's time. So if you don't mind spending a little bit more and you want to cut the time to see those results, this is the product that I would reach for."

FADE DARK SPOTS FAST - Best Dark Spot Serums 2026
"This packs a punch. Is it the cheapest product out there? It isn't, but I think you're paying for the technology in here because not only do you have all those amazing ingredients, they actually use some technologies to help them get into the skin where they need to be in order to deliver the results. So this definitely definitely delivers. Absolutely love it. If your budget can stretch to it, it's a great really sensitive skin friendly option."
#1 HYPERPIGMENTATION SERUM 2025 - Fade Dark Spots Fast
"This is a much more gentle yet still super effective version of a more potent option. Similar price point and delivers very similar results, but I'd say the risk of any sensitivity and irritation is going to be less with this because of the formula and the ingredients that they've chosen. You've got your acid in here in a really high concentration that's going to suppress any excess pigment production, but also help achieve a more even skin tone. You've got arbutin, which is fantastic. One of the best over-the-counter hyperpigmentation treatments to lift, to brighten, and to break apart some of that hyperpigmentation. And you've also in here got some peptides that they've chosen specifically for their ability to fade hyperpigmentation. Peptides do it all, but you have to choose the right ones for what you're actually hoping to achieve, and they've been really carefully selected for this to help boost brightness, luminosity, and just fade any dark spots. They've also got some algal extracts as well as licorice root in here. Both are like nature's brightening ingredients that really do boost the potency of the product without also increasing the risk of side effects and irritation. I think this is absolutely phenomenal and if your budget will stretch to it, this is a real sensitive skin friendly option."

"Allies of Skin are relaunching their tranexamic acid based brightening serum with a reformulation. I loved it three years ago in its original form, and now it is updated with a better formulation, so I am very excited for it and want to do a three month wear test on it."

"This formula has 2% alpha arbutin, which is a really strong pigment inhibitor. I love to see it in a hyperpigmentation product. It's also a precursor to hydroquinone. And if you're not familiar with hydroquinone, it is the gold standard topical for treating any form of hyperpigmentation. It is prescription only within the United States and it's fantastic. It can work really well specifically when you combine it with a mild anti-inflammatory and with retinoid. However, it can be too irritating for some people. And so having a precursor of hydroquinone in the form of alpha arbutin allows you to have a lot of those similar pigment blocking abilities without the irritation without the big hit of hydroquinone to your skin. It also has 3% tranexamic acid in it which can be helpful for pigmentation as well particularly through an anti-inflammatory pathway. I use a lot of oral tranexamic acid in my office for the treatment of melasma, but there is some data to suggest that in its topical form, it can also be effective. This also has a brightening licorice root extract and other pigmentation ingredients. People see great results with this formula."
Yay
"Rather than relying on a singular brightening ingredient, this sensitive skin-friendly serum takes a multi-brightener strategy. It combines tranexamic acid, arbutin, niacinamide, and antioxidants all in this one perfectly thoughtfully layered, effective yet gentle bottle. It's ideal for someone seeking a daily brightening product that's going to be elegant, cosmetically really appealing, and sensitive skin friendly. The key ingredients here are the niacinamide, the reishi mushroom, and tranexamic acid. So if you're somebody with sensitive skin, you may want to start with this one."
Yay
"The next serum I'm going to use is by Allies of Skin. Their tranexamic acid and arbutin serum also for lightening and brightening."
