guide to the ordinary exfoliating products

So, what’s the best The Ordinary exfoliator? The Ordinary’s got like 10! different acid bottles that all look identical. Lactic Acid 10%, Glycolic Acid 7%, Mandelic whatever – just a bunch of percentages and words you don’t recognize.

You’re staring at them trying to figure out which one to grab and it’s genuinely a nightmare. Your friend’s obsessed with one, TikTok won’t shut up about another, some random person on Reddit claims a third one changed their life. And then you start thinking… wait, should I be using all of them? Do they stack? Is that why everyone’s skin looks better than mine?

That’s where things go sideways. People end up buying three or four different exfoliators because they think more = better results. Spoiler: it doesn’t. It just wrecks your skin barrier and leaves you wondering why your face is red and peeling.

These exfoliators all do different things-some clear breakouts, others fade dark spots or smooth texture. But you don’t need the whole collection. Let’s figure out which ONE is actually gonna work for your skin without turning your face into a disaster.

Why You Should Pick Only One The Ordinary Exfoliant

Stop exfoliating your skin so much. I repeat, stop exfoliating your skin so much. I’m serious. In the past few months, I’ve lost count of how many of you asked for my help because your skin was all dry and irritated. When I asked what you were using, it always turned out you were using 2 or 3 exfoliants in your skincare routines. Like, WTF? Look, I get it. You want ALL the benefits of ALL the ingredients. But that doesn’t give you flawless skin. It gives you a bad case of peeling, dryness and irritation.

This. Has. To. Stop. Now.

Skincare isn’t about using all the ingredients. It’s about figuring out what your skin needs so you can chose the ingredients that work best for you. That’s even more important when it comes to exfoliation. All exfoliants remove dead cells from your skin, making it smoother and brighter and fading away fine lines and dark spots. But each one has its own characteristics that makes it more suitable for this or that skin type.

That’s why The Ordinary has 6 exfoliating products: there’s one for everyone. (And no, you can’t get all of them because they’re cheap). To help you make the right choice for your skin, and get all the benefits of exfoliation without the side effects, I’ve put together this quick guide to all The Ordinary exfoliating products.

the ordinary glycolic acid toning solution

Best For Dry Skin: The Ordinary Glycolic Acid 7% Toning Solution (£7.70)

What it is: Glycolic acid is the smallest member of the Alpha Hydroxy Acids (AHA) family. Its small size allows it to penetrate skin deeply. This makes it more effective but also more irritating.

What it does: Like all chemical exfoliants, it dissolves the “glue” that holds skin cells together, so they can slough off. It also hydrates skin and, at 10% and higher concentrations, boosts the production of collagen (the protein that keeps skin firm). It’s also the best acid to fade away all kinds of dark spots, including those left behind by pimples.

Who should use it: Dry and sun damaged skin.

When to use it: In the PM, after cleansing. Start with a couple of times a week and increase to every other night. Don’t use on retinol nights.

Side effects: Glycolic acid can sting and irritate skin. If you’re new to it, start using it a couple of times a week and build up frequency gradually.

the ordinary salicylic acid 2 solution

Best For Oily And Acne-Prone Skin: The Ordinary Salicylic Acid 2% Solution (£6.10)

What it is: Salicylic Acid is only member of the Beta Hydroxy Acids (BHAs) family used in skincare. It’s oil-soluble, so it can penetrate deep inside the pores.

What it does: It removes dead cells both from the surface of your skin and the inside of your pores, getting rid of whiteheads, blackheads and pimples. It also has anti-inflammatory properties that reduce redness and irritations.

Who should use it: Oily and acne-prone skin types and anyone battling with pimples or blackheads. Also, no matter what your skin type is, if you have blackheads or whiteheads, you need salicylic acid. Nothing else will work. Period.

When to use it: In the PM after cleansing. Start a couple of times a week and increase frequency gradually to every other night. Do not use together with retinol.

Side effects: It’s rare, but it can cause allergies in some people (if you’re allergic to aspirin, don’t use this). Plus, it can also cause purging. You know all those pimples that were forming underneath the surface of your skin? Salicylic acid brings them all to the surface at once. It looks really bad for a few weeks and then you get your clear skin back because all the crap has gone.

Best For Oily and Acne-Prone Skin: The Ordinary Salicylic Acid 2% Anhydrous Solution (£6.80)

What it is: Salicylic acid is a BHA and it mixes with oil, so it actually gets inside your pores instead of just chilling on the surface like AHAs.

What it does: Goes into your pores and drags out all the nasty oil, dead skin, and junk causing your blackheads and breakouts. Also calms down pissed off zits while it’s at it. This one’s in oil which sounds stupid for oily skin but trust me it helps it work without totally drying you out.

Who should use it: Oily skin, acne, pores that are always clogged. Blackheads everywhere? This is your guy.

When to use it: Night after washing your face. Start like twice a week then go up if your skin’s not mad about it. Don’t use it the same night as retinol or anything else harsh when you’re just starting.

Side effects: Can dry you out or irritate you if you use too much. Might purge at first-more breakouts while everything comes out. Face getting super dry and flaky? Back off.

the ordinary lactic acid 10 + ha 2 01

Best For Sensitive Skin: The Ordinary Lactic Acid 5% + HA 2% (£5.50) & Lactic Acid 10% + HA 2% (£5.80)

What it is: Lactic acid is a member of the Alpha Hydroxy Acids (AHAs) family. It’s bigger than glycolic acid so it can’t penetrate skin as well.

What it does: It dissolves the “glue” that holds skin cells together (so they can slough off) and hydrates skin. The result is softer, smoother, and brighter skin.

Who should use it: Sensitive skin that can’t tolerate glycolic acid. It works slower than glycolic acid, but that also means lower risk of side effects. For your skin type, that’s a win.

When to use it: In the PM, after cleansing. Start with once a week and increase to twice. If your skin can tolerate three times a week, great. Don’t do more than that. Once or twice a week is more than enough for sensitive skin. And do not mix it with retinoids and other harsh actives.

Side effects: Lactic acid is one of the gentlest exfoliating acids. But if you have sensitive skin, don’t use it more than once or twice a week. Also, start with Lactic Acid 5% + HA 2% and upgrade to the higher version later on.

What it is: Saccharomyces ferment is yeast extract that’s been fermented. It’s supposed to be a gentler alternative to traditional acids, acting more like a hydrating treatment than a true exfoliator.

What it does: Honestly? Not much. It’s meant to brighten and smooth skin without the irritation of AHAs or BHAs, but the results are so mild most people don’t see any real difference. The ferment is supposed to boost hydration and give you that “glowy” skin, but you can get way better results from actual exfoliating acids.

Who should use it: People with extremely sensitive skin who can’t handle any real acids. But even then, there are better gentle options out there.

When to use it: Morning or evening after cleansing, but honestly, save your money.

Side effects: It’s gentle enough that irritation isn’t really an issue. The problem is it’s too gentle to do anything useful.

the ordinary mandelic acid 10 + HA

Best For Sensitive, Acne-Prone Skin: The Ordinary Mandelic Acid 10% + HA (£7.40)

What it is: Mandelic Acid is a member of the Alpha Hydroxy Acid Family. It’s twice the size of glycolic acid, so it penetrates skin very slowly. That makes it less effective than GA but a lot less irritating too.

What it does: It unglues dead skin cells, so they can slough off. It also has antibacterial and anti-inflammatory properties that help fight acne.

Who should use it: Sensitive, acne-prone skin. Personally, I believe Salicylic acid to be a better choice for acne-prone skin. But, if for some reason, your skin can’t tolerate that, it’s good to have another option to fall back on.

When to use it: in the PM, after cleansing. Again, start with twice a week and increase frequently to every other day only if your skin can take it. Do not mix with retinoids.

Side effects: It can cause irritation if used too often.

Best For Lips: The Ordinary PHA 5% Exfoliating Lip Serum (£7.60)

What it is: Gluconolactone is a PHA (Polyhydroxy Acid), the gentler cousin of AHAs. Bigger molecules, less penetration, supposedly won’t wreck your lips.

What it does: Exfoliates dead skin off your lips to make them smoother. Gets rid of flakes so your lip balm can actually sink in instead of sitting on top of crusty skin.

Who should use it: Honestly? Nobody really needs this. Your lips shed dead skin on their own just fine. But if you have a special occasion to go to, this can help.

When to use it: I’d only use it once a week tops. The skin on your lips is very thin, so you don’t want to strip too much.

Side effects: PHAs are gentle so irritation’s unlikely. Might tingle a bit but shouldn’t hurt. But here’s the thing: why risk irritating your lips when a good lip balm and staying hydrated does the job? This is one of those products that sounds fancy but doesn’t solve a problem that actually exists. Your lips don’t need chemical exfoliation.

the ordinary aha 30% + BHA 2% Peeling Solution review 01

Best For PRO Users: The Ordinary AHA 30% + BHA 2% Peeling Solution (£8.90)

What it is: A peeling solution with 30% Alpha Hydroxy Acids (Glycolic/Lactic/Tartaric/Citric) and 2% Beta Hydroxy Acid (Salicylic Acid).

What it does: It dissolves the “glue” that holds skin cells together, making skin brighter and smoother. It also unclogs pores and fights acne.

Who should use it: Anyone who needs the big guns to fight wrinkles and hyperpigmentation – and has built tolerance to these acids over the years.

When to use it: In the PM after cleansing. The Ordinary says not to use more than twice a week but I wouldn’t use it more than twice a month. This stuff is strong!

Side effects: It can seriously peel, irritate and dry out the skin. If you have sensitive skin, don’t go anywhere near this. If you don’t and want to use it, don’t use other exfoliants or retinoids for a couple of days before and after the peel.

Available at: Sephora, SpaceNK, The Ordinary and Ulta

Best For Acne, Rosacea, & Pregnancy: The Ordinary Azelaic Acid Suspension 10% (£27.40)

What it is: So azelaic acid is made by yeast that already lives on your face. Wild, right? Skincare companies just make a synthetic version and crank up the concentration so it actually does something.

What it does: It’s not really an exfoliant in the way Glycolic or Lactic are. It doesn’t speed up cell turnover like they do. Instead it unclogs pores by normalizing how your skin sheds cells, kills the bacteria giving you zits, calms down redness and inflammation, and fades dark spots.

Who should use it: This is the best exfoliant for pregnant women with acne or rosacea. Unlike other acids, this is safe for mum and baby. It’s also safe for people with sensitive skin who can’t tolerate harsh acne treatments like benzoyl peroxide.

When to use it: At night after you wash your face. Once you’re used to it you can do it every night. You can throw other stuff on top but don’t go crazy right away.

Side effects: Might tingle or make you a bit red when you start. Sometimes it gets all pilly under makeup which is annoying as hell. Sensitive skin? Test it somewhere first. Oh, and it can cause purging too.

FAQs About The Ordinary Exfoliants

Can I use The Ordinary’s Glycolic Acid and Lactic Acid together?

Nah don’t. They’re both AHAs so you’re just gonna wreck your face. Your skin doesn’t need two different AHAs at once – that’s overkill and you’ll end up irritated, red, and with a messed up skin barrier. Pick one. Glycolic if you want dark spots gone faster since it goes deeper. Lactic if you need something that works but won’t destroy you. Once you pick one and use it for like a month, you’ll see stuff happen. Jumping between both or layering them just confuses your skin and makes things worse.

What’s the difference between The Ordinary’s Lactic Acid 5% and 10%?

10% is stronger, works faster, but irritates more. New to acids or kinda sensitive? Start with 5%. Use it for like 3-4 weeks and if your skin’s totally cool with it and you’re not seeing enough, bump up to 10%. Don’t just go straight to 10% thinking bigger number means better – your face might lose it and then you’re dealing with irritation and peeling and regretting everything. Work your way up, it’s not a race.

Should I use The Ordinary’s Mandelic Acid or Lactic Acid for sensitive skin?

Mandelic for sure. It’s got the biggest molecules out of all the AHAs so it doesn’t penetrate as deep, which means way less chance of irritation. Lactic’s gentler than Glycolic but Mandelic’s the most chill option they make. If your skin’s sensitive or reactive or you’re just nervous about trying acids, start with Mandelic. It’s the safest bet and you can always go stronger later if you need to.

Which is better: The Ordinary’s Salicylic Acid 2% Solution or the Anhydrous version?

Anhydrous is what most people go for. The regular Solution is water-based and some people find it more drying. The Anhydrous one’s in oil which sounds backwards for oily acne skin but people seem to like it better because it’s less drying on your face. It’s like a pound more expensive so not a big deal. Try whichever one, if one’s drying you out or not working, switch to the other. They both have the same amount of salicylic acid so they’ll both clear your pores, just different bases.

Which The Ordinary exfoliator is the best overall?

There isn’t one that’s magically better than the rest. It’s whichever one fixes YOUR specific problem. Got clogged pores and blackheads? Salicylic. Dark spots and dull skin? Glycolic. Sensitive skin freaking out? Lactic. Everyone’s skin is different so what works amazing for your friend might do nothing for you or make you worse. Stop looking for some perfect universal answer and just match it to what your actual skin issue is right now

The Bottom Line

What’s the best The Ordinary exfoliator? Depends what’s going on with your face.
Dry skin, dark spots? Glycolic. Breaking out, pores clogged? Salicylic. Acne plus redness? Azelaic. Sensitive skin? Lactic or Mandelic and go slow.
Everyone makes the same mistake: buys a bunch thinking more is better. It’s not. You’ll just trash your skin barrier and end up worse.
Pick one. Use it. Give it a month at least. Wear sunscreen. Stop overthinking this.
