Caprylic/Capric Triglyceride is an emollient, solvent, and texture enhancer. It is considered a skin-softener by helping the skin prevent moisture loss.
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.

Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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.

I made this work eventually.
I was intrigued when I first saw this product as most salicylic acid treatments that I’ve seen are in water based formulas. I however have dry AND acne prone skin so finding acne fighting + moisturizing products can be a little challenging. This did technically work for me as I did notice an improvement with pore appearance and blackheads, but it was also too easy for me to over do it. I think it’s because of the anhydrous formulation of this product, but this is really able to penetrate deep so as to exfoliate and clean out your pores. This however often left my skin red, so I began using this as part of my cleansing steps instead and I think it’s been helping. I apply and massage in my oil cleanser and then I put several drops of this product on the areas where I struggle the most with pores/blackheads (keep this away from your eyes!) and I continue massaging for a couple of minutes. By mixing this with my oil cleanser I’ve made it so it is able to be emulsified and then washed off. That way it won’t over exfoliate my skin. I’m glad I found a way to use this up as I don’t like wasting products, but I’m not sure if I’ll repurchase this. If you have tough skin and you need something that will get deep into your pores than I’d say to give this a try as it’s inexpensive. It’s good and it does work, but for me I think I’ll just stick to gentler exfoliating products once I finish this one.

Started using this product around 3-4 months ago. I have noticed a complete transformation in my acne. I had been using products with “fatty alcohols” (Cerave), and unfortunately broke out.. bad. I had a ton of deep painful spots, majority on my chin and forehead. This product completely cleared/healed those spots within one month of use. Since then I have noticed, if I do get a spot, it appears much smaller and heals much faster. Of course this might not work for everyone. But to me this is a holy grail. The Ordinary does have some hit or miss products but this has seriously saved my skin.

Game changer. This stuff is amazing for fungal acne, other BHA acids were too harsh for my sensitive skin and didn’t improve any of my concerns, but this stuff is strong and non irritating. Didn't give me any new breakouts just surfaced all of my pre-existing acne. Turned all my FA into white heads in a matter of weeks. This with the ordinary 5% lactic acid serum is completely reviving the texture and colour of my skin - just make sure if you use both to alternate one in the morning and one in the evening !!!

Very good for acne
Saw an immediate overnight change in my inflammation overnight after using for the first time, haven't had any inflammatory whiteheads since I finished purging (which lasted 2 weeks) and my skin is slightly less oily. However it did nothing really for my sebaceous filaments.
