What the gurus are saying

This serum brings together multiple ingredients that work on dark spots from different angles: tranexamic acid and niacinamide both target hyperpigmentation, but through separate pathways, which gurus say tends to yield better results than a single active alone. Bakuchiol in the formula acts like a gentler retinol alternative, delivering similar benefits to skin without the irritation, so it pairs well for those already managing sensitivity or using other actives. The main thing to keep in mind is the price point, which sits on the higher end, though the combination of proven actives and solid packaging earns approval across the board.

"Paula's Choice Discoloration Repair Serum is nave safe and contains tranexamic acid. It is £46, so it is an expensive product. Paula's Choice generally is a little bit more on the expensive side. I love the product. I love the packaging."

"I just picked this up mainly because it's got bakuchiol in there, which is like an alternative to retinol. There's a lot of studies that look at bakuchiol and look at its effectiveness in comparison to retinol, so it does pretty much a similar thing to retinol but doesn't have the sensitivity. Good retinol formulations nowadays have bakuchiol on it because they just take down the concentration of retinol, build it up with bakuchiol, and then suddenly you've got something that you can use all the time."

The Truth About Tranexamic Acid Serum

"Paula's Choice Discoloration Repair Serum has 3% tranexamic acid but it also has 5% niacinamide. Niacinamide, like tranexamic acid, is a good ingredient for dark spots and redness. It's anti-inflammatory, and niacinamide has a lot more research supporting that it does these things. I like that it's included because when treating dark spots and hyperpigmentation, it's not usually just one ingredient. Having multiple ingredients that target different arms of the pigment pathway really can lend better results. Niacinamide specifically works for hyperpigmentation because it slows down the spread of those pigment packets that are produced in the melanocytes to the neighboring keratinocytes, which is totally different from how tranexamic acid works for dark spots by targeting the plasminogen pathway."

"Paula's Choice Discoloration Repair Serum can be used depending upon your budget and availability. For achieving an even skin tone, serums that contain skin lightening agents which reduce melanin production are important. Paula's Choice Discoloration Repair Serum contains ingredients like kojic acid, alpha arbutin, azelaic acid, licorice extract, and niacinamide that can help in reducing dark spots."
