Level Serum.

"The first one is the Regimen Lab Level serum. This one's got a ton of other brightening ingredients in it as well. Niacinamide, tranexamic acid, alpha arbutin, and licorice root. So this one's a nice do it all kind of brightening product as well."

"This is my fourth bottle now, it's 42 bucks. In here we've got niacinamide, tranexamic acid, acetyl glucosamine, alpha arbutin, licorice, curcumin which is a compound from turmeric, and then hexyl resveratrol for brightening. This one's really nice, acne-prone skin friendly, actually pretty friendly for all skin types. It's got some nice ingredients in there that aren't in a few of these, such as the hexyl resveratrol."

"Regimen Lab Level Serum, this stuff's wonderful for hyperpigmentation, melasma, dark spots. It's got a light water texture I really enjoy. I finish this one up and I'll definitely pick up another one. This is certainly something I would come back to in the future."

"There's a wide variety of brightening and pigmentation fighting ingredients in here, uses five different lighting ingredients as well as salicylic acid. It's friendly for all skin types including dry, oily, sensitive, and acne-prone skin with no ingredients that would be irritating for acne-prone skin. That's amazing that they can include this many different ingredients to brighten up skin and not irritate any skin types or be too much or too drying or too oily or too greasy. Once it's soaked in it kind of sets to a slightly radiant finish. In terms of the price, this stuff is a bargain: 30 milliliters for 18 bucks, that's a really good deal. I really enjoyed this one and I highly recommend it for people with melasma, sunspots, dark spots, and hyperpigmentation issues."

"The Regimen Lab Level Serum is amazing, it's great for that if your skin isn't sensitive to fragrance."

"Regimen Lab Level Serum is really wonderful. In here we've got niacinamide, tranexamic acid, acetyl glucosamine, alpha arbutin, sepy white, licorice extract, and a turmeric-based active tetrahydrofurolmethine from the turmeric plant, and then hexorescinol. This one is absolutely lovely. It's a little bit more pricey than some of the other options, but they do have sales from time to time where you can pick it up with a set."

"My favorite from them is their Level serum. It's a great brightening serum. I've repurchased that at least three times now and finished them all, so definitely time to pick up another one."

"If you suffer from hyperpigmentation, dark spots, melasma, or PIE, Regimen Lab Level Serum is a great brightening serum worth checking out. It contains some nice ingredients that are pretty friendly for most skin types, there's no fragrance in it, it's pretty affordable, and a bottle will last you a while. It's a winner for hyperpigmentation, dark spots, and uneven skin tone."

"The Regimen Lab Level Serum is in my top picks. This one contains [tranexamic] acid and a bunch of other good ones for brightening."

"Regimen Lab Level Serum, this stuff's very impressive. So in here we've got niacinamide, we've got tranexamic acid, got alpha arbutin, we've got licorice root and we've got hexylresorcinol and all of those ingredients are good at fighting pigmentation, clearing it up and some of them are good at preventing it from forming so you can treat ones that exist and then also prevent new hyperpigmentation from forming with certain ingredients. This one's really nice, it's pretty affordable. The texture is water light so you can fit it into your routine really really easily without having to change anything else around. I've repurchased it three times now. You can use it morning or evening routine."

"I'm going with the Regimen Lab Level Serum for brightening and that's why I applied a kind of neutral product in between the ultimate serum which has a lot of peptides and something like this which has some tranexamic acid in things I think it helps play better with the other products if you apply something in between a friendly product that works good between both of them. I just love this serum because hyperpigmentation melasma are a pain to get rid of if you ever can get rid of them, especially melasma once you've got it it's difficult to get rid of it if not impossible but you can make it a lot less noticeable by using brightening products and sunscreen and stay out of the bright lights."

"The Regimen Lab Level Serum for brightening your skin up, it's really nice product and really good brightening ingredients. So if you have melasma, hyperpigmentation, this one is worth a try. I think this is my fourth bottle of it now and I really love it for all of those reasons."

"The Regimen Lab Level serum, hands down for hyperpigmentation and melasma, one of my most often recommended products. In here we've got niacinamide, tranexamic acid, alpha arbutin, licorice root, and hexyl resveratrol. This stuff is really nice, fragrance-free. A little bit goes a long way. It might look initially a little pricey, but a bottle like this that's 1 oz with daily use will last I would say 2 to 3 months because it's super light. Less than a pump is enough to cover your whole face, so it's a very nice product."

"I've got the Regimen Lab Level Serum, third, fourth bottle of this, fifth maybe, I don't know. It's wonderful. So in here we've got niacinamide, we've got cetyl glucosamine, tranexamic acid, alpha arbutin, an ingredient called underoyl phenoline, licorice root, and hexosorcinol. So this one's got a few ingredients that none of the other ones have as well, so something worth considering to try if you've tried a lot of other brightening products. This one's really affordable, 17 bucks I think, not on sale."

"This brightening serum is wonderful if you have hyperpigmentation or melasma, dark spots, anything, even UV damage. It's really nice at brightening your skin. I would put it in my top ten of brightening products, probably my top five. I love this stuff, it's wonderful."

"You've got your tranexamic acid. You've got your blend of different acids in terms of exfoliators and hyperpigmentation treatments. And you've got some brightening agents too. I'd say this is definitely up there in terms of potency. So, if you have very sensitive skin, this might not be for you. But if your skin is more resilient, not prone to sensitivity, this could work really, really well. I tried it and I started to see results in about 9, 10 weeks time. So again, super quick turnaround and a really nice option, particularly if you're shopping in the US or Canada where Regimen Lab is really easy to get your hands on. I love this."

"The Regimen Lab Level Serum has multiple different actives to target your hyperpigmentation. It's at a similar high price point, so not for those on a budget, but it does work quite nicely. It's in more of a serum consistency, it's super high potency, packs a punch, but with that comes that risk of sensitivity. If you're looking for something that really packs a punch, you're less concerned about budget and sensitivity, and you just want those quick results, I definitely think reaching for the Regimen Lab Level Serum will give you a really quick turnaround. The impatient among us will definitely have that need for quick results satisfied."
