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. If you see this, drink a glass of water. Stay hydrated!
Learn more about WaterThis ingredient comes as a powder made up of small, porous, microbeads. It is used to add a silky feel to products and also helps absorb oil.
Capryloyl Salicylic Acid comes from salicylic acid, the famous acne-fighting BHA.
It usually goes by a more common name of LHA, or lipohydroxy acid.
Like salicylic acid, this ingredient is a chemical exfoliant that can help break down the oil in your pores and reduce inflammation.
Though studies for LHA do show it to be less effective than salicylic acid. To be fair, salicylic acid is the reigning monarch of acne treatments.
However, a study from 2009 found LHA to be comparable to BPO, making it a good alternative for people with sensitive skin. Another study of 14 patients found a significant decrease in comedones after using LHA.
Another pro of LHA? It is less irritating than salicylic acid due to its large molecule size.
Large molecules cannot penetrate skin as well, so they are gentler on the skin. LHA is much less penetrative than salicylic acid.
An in-vitro study (not done on a living organism) found only 6% of LHA penetrated past the statum corneum compared to 58% of salicylic acid. An in-vivo (done on a living organism) analysis revealed ~17% of LHA was still present in the top layer of skin after 4 days, versus ~9% of salicylic acid.
Interestingly, a study from 2008 found LHA comparable to another famous acid, glycolic acid.
This study found about 10% of LHA is as effective as 20-50% of glycolic acid in treating hyperpigmentation and fine-lines.
Hydroxy acids have been found to stimulate skin protein, lipids, and thermal thickening. This may have anti-aging benefits.
Learn more about Capryloyl Salicylic AcidSilica is a mineral naturally found in our skin. It helps to thicken and smooth the texture of a product. It also acts as an agent for other ingredients by increasing the absorption of other ingredients into the skin.
Silica is often used for absorption and can help reduce shine when products are applied. Silica occurs in naturally in materials like clay and sandstone, and it can also be produced synthetically.
Silica is present naturally within the skin during collagen production and when reducing inflammation.

Good, but wouldn't repurchase it again
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.
Broke me out!
After applying the product my skin immediately turned red and irritated and started feeling itchy. My skin never reacts this way! Dont recommend for dry skin
