Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Skin Conditioning, Solvent

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!

Skin Conditioning, Solvent

Pentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.

The hydrophilic trait of Pentylene Glycol makes it a humectant. As a humectant, Pentylene Glycol helps draw moisture from the air to your skin. This can help keep your skin hydrated.

This property also makes Pentylene Glycol a great texture enhancer. It can also help thicken or stabilize a product.

Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.

Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.

Pentylene Glycol has a low molecular weight and is part of the 1,2-glycol family.

Buffering

Sodium 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.

Buffering, Masking

Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).

As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and even out skin tone.

If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.

I think Azelaic Acid is a very underrated exfoliating active ingredient, I'd say almost indispensable for acne-prone skin. It's extremely effective on large, inflamed pimples and whiteheads. And on top of that, it has a great effect on pigmentation spots and oil production. I find this facial treatment very good because it doesn't peel at all and absorbs well. It makes excellent use of all the Show more

This product was horrible for me! First I got it recommended by a pharmacist for my face, but back then it was too tingly and I stopped using it. Now because I’ve gotten a bit bacne I would use it there. Apparently I might be allergic, and now I have to throw it out for good! I don’t know who’s face can tolerate this concentrated serum :/

Worth the try for ACNE skin
I used it for about 2 years and I was more than satisfied. Upon returning on my Erasmus trip, it broke me out and made my skin dry. I don't know if anything happened during the trip but right now I don't use it. It's really good if you have taken acne treatment pills and you need smt to keep the acne away (from my experience at least).
