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.

The Ordinary Lactic Acid 5% + HA 15 ingredients
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

Single-handedly cleared up my ever present stubborn blackheads!
I started using this product during the day and layering it under my sunscreen. It wasn't bad for that, but I just find using it at night is much more effective. It is a thick enough consistency that it can go on as the last layer of a night-time routine and act as an overnight mask.
I love the BHA liquid exfoliant and use that during the day now, due to its quick absorption. I am not able to Show more
