Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

The Ordinary AHA 30% + BHA 2% Peeling Solution contains this as ingredient number 2.
Salicylic Acid (also known as beta hydroxy acid or BHA) is one of the most well-known ingredients for treating skin that struggles with blackheads and acne. It helps to exfoliate both the skin's surface and pores, and also acts as an anti-inflammatory agent.
This multitasking property makes it a great ingredient for cleaning out pores, controlling oil production, and reducing inflammation.
Unlike AHAs which are water soluble, Salicylic Acid is oil soluble. This means that it's able to exfoliate the inside of pores and reduce blackheads.
Concentrations of 0.5-2% are recognized by the U.S. FDA as an over-the-counter topical acne product.
It can cause irritation and/or dryness if one's skin already has a compromised moisture barrier, so it's best to focus on repairing that before introducing a Salicylic Acid into your routine.
In general, Salicylic Acid is a great ingredient for oily acne-prone skin.
While salicylic acid does not increase sun-sensitivity, we still recommend wearing SPF.

The Ordinary AHA 30% + BHA 2% Peeling Solution contains this as ingredient number 8.
Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.
In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.
Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.
"Alkaline" refers to a high pH level. A low pH level would be considered acidic.

The Ordinary AHA 30% + BHA 2% Peeling Solution contains this as ingredient number 4.
Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny.
On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together.
Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.

The Ordinary AHA 30% + BHA 2% Peeling Solution contains this as ingredient number 18.
Pentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.
The hydrophilic trait of Pentylene Glycol makes it a humectant. As a humectant, Pentylene Glycol helps draw moisture from the air to your skin. This can help keep your skin hydrated.
This property also makes Pentylene Glycol a great texture enhancer. It can help thicken or emulsify a product. Emulsifiers help stabilize a product. It does this by preventing certain ingredients from separating.
Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.
Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.
Pentylene Glycol has a low molecular weight and is part of the 1,2-glycol family.

The Ordinary AHA 30% + BHA 2% Peeling Solution contains this as ingredient number 17.

Speaking anecdotally, please be very well informed and careful if you choose to use this product. While this product contains both AHA and BHA chemical exfoliants I will be emphasizing its AHA content as a potential safety/irritant concern to the skin. Alpha hydroxy acids in this concentration can very easily over-exfoliate by stripping corneocytes from, or desquamating, the outermost stratum corneum of the epidermis. While this product formulation is vague about specific AHA composition of “30%”, The Ordinary’s website states that glycolic acid is the primary alpha hydroxy acid in their formula. Current clinical research (and the FDA) has established a general consensus that the concentration of AHAs for safe routine use in over the counter products is approximately in the figure range of 2-10%. For reference, dermatologists with over 8 years of medical and residency training perform chemical peels with glycolic acid ranging in concentration anywhere from 20-70% depending on intended penetration of the stratum corneum. With that said, there are some individuals with skin who can tolerate this level of exfoliation, but my personal philosophy is that less is more with chemical exfoliants. If you are thinking about using this product please do your due diligence and look into open-access research on chemical exfoliants, consider all exfoliant options side-by-side/if a chemical exfoliant is right for you, and understand your skin’s sensitivity level before jumping to one product.

one of my fav chemical exfoliators. i recommend this for people with oily/acne-prone skin, those with dry or sensitive types should probably avoid.
NOTES: please be careful with this. i’ve seen so many people use this product incorrectly and would end up getting a bad reaction (like literally burning their face). then leave bad review without having used it properly. this is a CHEMICAL exfoliating peel, it will sting but it should NEVER burn. if it does, your skin either cannot handle it or it was applied wrong.
here’s how to make sure it’s being used correctly:
- don’t use it with any clashing ingredients in your other products. (ex: vitamin C)
- don’t use it if you have open wounds (picked pimples)
- make sure your skin is completely dry before application, only use 2-3 drops or enough to cover your face.
- it should be a thin red layer, not thick, or you’ll burn your skin.
- AVOID APPLYING ON EYE AREA
- do NOT leave it on for more than 10 minutes, even if you don’t feel anything. you will completely strip and damage your skin.
- make sure to use sunscreen every morning while using this.
i use this once a week at night time after i cleanse my face. i first started to notice a difference after a couple weeks of use, my breakouts were disappearing and it reduced the bumps on my skin. it does an excellent job of improving skin texture and removing blackheads/blemishes. my skin always feels so smooth after use. it helped a lot of my dark spots and acne scars fade. i also love how cheap this is, a holy grail under $10.
the only things i don’t like about this is the sensation and smell. it doesn’t hurt (no skincare product should anyway) but it does sting, which is to be expected of. it has a weird smell to it, i’m not sure how to describe it but it’s not bad. i personally don’t mind fragrance as it doesn’t bother my sense of smell or irritate my skin. this product could be irritating to others though. it all entirely depends on your skin.
