EmollientIngredients 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.

Honestly I was skeptical because it took my skin the FULL 12+ weeks to adjust to this. It was my first time using a retinoid and the purging was rough, but genuinely I’ve never seen my skin look so good after the purging ended. It absorbs well and a little goes a long way. I had to stop using it because I got too crazy with actives and I messed up my skin barrier super bad, but I’m hoping I can go Show more
I've been using this on and off for around 2 years. I thought this was going to help my acne, but looking back at pictures I actually think it's made my acne worse! It's made my acne areas really inflamed and red with angry spots. Think it's time to cut it out of my routine... Given it 2 stars as it soaks in pretty fast and is hydrating.

Holy grail for real. This stuff works instantly overnight to sooth acne and balance skin tone/texture. Everytime I do some damage picking at my skin, this serum basically undoes it all. Fantastic for maintenance whilst purging acne, I use this in rotation with the inkey list BHA serum and they have resurfaced and evened out all my fungal acne, going to move onto the 10% for clearing up my scars Show more
🤍 been using this for 2 years now, and i've really seen significant changes in my skin—especially with hyperpigmentation and texture ♡ however, it can be a bit irritating since i have sensitive skin, and it feels a little harsh when i combine it with the niacinamide 10% + zinc from the ordinary too. so, on my heavier days where my skin is extra sensitive, i skip this serum and just use moisturizer Show more
