A hydrating serum combining 2% aloe and 2% N-acetyl glucosamine (NAG) designed to soothe skin, improve hydration, and help fade hyperpigmentation and post-acne marks.
This serum earns consistent praise for calming sensitive skin and fading post-acne redness and dark spots, especially when used consistently over several months. Most gurus highlight its gentle hydration and work on uneven tone, though one dermatologist remained skeptical of whether it outperforms other serums in The Ordinary's range. Those tackling hyperpigmentation or post-acne concerns may want to avoid pairing it with direct acids like glycolic acid or vitamin C, as the ingredients conflict.

"This is one of those products just everybody should have in their skincare routine. It hydrates, it plumps, it nourishes, but most importantly, it turbocharges your hyperpigmentation routine. If you're somebody that's already using hyperpigmentation actives such as maybe vitamin C, tranexamic acid, alpha, all the good stuff, use this to just turbocharge it. It's super gentle, so even the most sensitive skin can absolutely use it."

THE BEST EXFOLIATOR - Shrink Pores Fast ( The Ordinary Milky Toner Review )
"I have been loving for so so long. You get 2% concentration of NAG in here, and NAG is that key exfoliating ingredient. The Ordinary say that the way this works in terms of exfoliation without the traditional chemical exfoliants, those acids, is that it actually prevents some of the glue which sticks old dead skin cells onto the gorgeous radiant skin beneath it. It actually prevents that glue sticking to those dead skin cells, which makes it a lot easier to just be washed away and exfoliated."

So it's like a multi-pronged attack and works so well. I'm quite lavish with this, I use a fair amount of it twice a day every day.

Winner or Loser?!?! 🧐 The Ordinary Skincare New! Aloe 2% + NAG 2% Solution For Soothing & Dark Spots
"For using this for just over a month, I didn't really notice any crazy results, any benefits, any difference in dark spots or hyperpigmentation. However, some of these ingredients based on the studies that were done were based on eight weeks, so that's probably not a great judge of it. [...] A lot of ingredients you need to use three, four, five, six, seven, eight months. Things like azelaic acid take three, four [...] months, retinoids again three, four months."

"This is a great skin treatment for pre or post acne skin, but I particularly appreciate how this addresses so many post acne visible appearance concerns. [...] This reduces the appearance of post-inflammatory erythema, all those bright red marks that take forever usually to fade and are impossible to conceal in any natural looking way. But this also helps with post acne skin texture as well."
"This particular product from the ordinary hasn't really been doing it for me, but if you have a lot of hyperpigmentation it may help."

Dermatologist reviews *NEW* SKINCARE FROM THE ORDINARY
"I thought maybe this will improve skin texture and overall the clarity of my skin. Overall I'm very skeptical of this product, not because it's problematic or the ingredients I think are harmful per se, I just am not really sure it is offering the consumer that much above and beyond some of the other serums in The Ordinary's portfolio for which the ingredients are a lot more evidence-based."
Are The Ordinary's New Serums Any Good? My Updated Thoughts
"I've been trying to make my way through The Ordinary Aloe 2% + NAG 2% Solution, actually I made quite a dent in it. [...] It's not really doing much for me but I think it can be beneficial for some people with hyperpigmentation, dark spots, discoloration. The ingredient N-acetyl glucosamine, it's actually very hydrating just by itself but it also may help with improving dark spots."
EXFOLIATING MY FACE & SCALP
"I find it unusual that The Ordinary did not put niacinamide in the serum because NAG and acetyl glucosamine has been shown to be useful for fading hyperpigmentation and lightening dark spots when used in conjunction with niacinamide. They tackle different arms of the pigment pathway. I don't really see much of a difference with this product. I don't see enhanced skin luminosity, radiance, or anything."
MORNING SKINCARE ROUTINE & SHOPPING FOR SKINCARE AT MARSHALLS
"I really don't feel like this does much if I'm being honest. I prefer the Timeless one because the formula is very moisturizing and [...] has a nice emollient property to it that softens and smooths the skin. [...] This is one of those where you have to have a lot of faith that it's doing something because I don't see any enhanced radiance with it and it kind of just feels like I'm putting water on my face."

"This particular product from the ordinary hasn't really been doing it for me, but if you have a lot of hyperpigmentation it may help."
"Aloe plus NAG solution, which is a new launch from The Ordinary, the products are fabulous. Aloe also works as a tyrosine inhibitor and has fantastic properties for lightning and brightening the skin in the most gentle manner. [...] This routine is going to work over a three to four month period depending on area pigmentation, and I promise you this will lighten and brighten your intimate areas in a gentle manner as you have never seen before."
"That serum really does work as long as you are consistent with it, so perfect for those that have acne skin. NAG is a non-acidic alternative to, let's say, alpha hydroxy acid, so it's very gentle, perfect for all skin types, but it's not that true acid ingredient that could irritate your skin. Instead it's an amino acid sugar that hydrates the skin but also improves that uneven skin tone while brightening up the skin at the same time."

"It really does help to fade it a lot quicker and it really is a lovely serum to use if you have these skin concerns. There are some conflicts with this serum according to The Ordinary, so you don't want to be pairing this up with your direct acids like salicylic acid, glycolic, or lactic acid, any type of exfoliating ingredient. [...] You don't want to use this with vitamin C like L-ascorbic acid, Resveratrol plus ferulic acid. These are types of ingredients that you do want to stay away from."
What the evidence says.
Independent of what the gurus think, this is what
the published research supports about the main active ingredients here.
Alpha hydroxy acids
Alpha hydroxy acids loosen the bonds holding dead cells at the surface. The evidence supports smoother texture and more even tone over time, and they can leave skin more sensitive to sun.
Peptides are short protein fragments meant to signal repair. The evidence for them is thinner than for retinoids or vitamin C, and it varies a lot by the specific peptide, so the category is more promising than proven.
