Ingredients Side-by-side
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 WaterSodium 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.

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.

interesting to say the least
no one warned me about the purge i was gonna get from this. the crease on my nose and my chin turned red and were peeling for weeks but i think it paid off in the end. it handled my sebum production and pimples very well, but unfortunately i can't say the same for my blackheads and whiteheads, which remained unbothered by this product. another thing i wasn't warned about when i used this is that it is not hydrating enough to be used as a moisturiser. i only realised this when i switched to byoma's gel cream moisturiser but you have to use this as a facial or spot treatment and follow up with a proper moisturiser. overall i liked this but i had to stop using it because it was constantly sold out and i think it is so expensive right now and i also needed to stop using benzyl peroxide so i can switch to retinol.
