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!

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.
As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.
Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.
In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.
This ingredient is organic, colorless, odorless, and non-toxic.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Dimethicone is a silicone used for making products smooth and silky. It also has the added benefit of sealing in hydration. The amount of dimethicone found in beauty products is considered safe and non-comedogenic, meaning it won't clog pores.
Dimethicone has been found increase absorption in skin, boosting the benefits of other ingredients. While there is concern for the safety of dimethicone, the levels used in skincare are safe for use.

La Roche-Posay Effaclar Duo(+) SkinCorrecteur contains this as ingredient number 3.
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.

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.

Paula's Choice at it again with cetearyl alcohol high up on the ingredient list. I'm disappointed by their ingredients fairly consistently now.

Did nothing for my fungal acne. Actually did nothing at all.
(Compared to my cheap no-name Russian brand Azelaic acid cream which worked wonders).

I bought it after SOOO many reviews on tiktok. I tried it and it was really good and matte on my skin. I didn't felt that I needed that (cause I was using the effaclar serum too) so I didn't repurchased again. Would recommend for someone with acne prone skin, looking for a matte gel that feels like a moisturizer.
It’s fine
Been using this product as a spot treatment for my breakouts. It didn’t really do much to it. The texture is nice and lightweight but as a moisturizer it’s drying, honestly I wouldn’t repurchase this product again.
