Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Potassium Azeloyl Diglycinate (PAD) comes from the condensation of azelaic acid mixed with glycine.
This ingredient has similar properties to azelaic acid; it can help reduce sebum production and soothe skin. PAD also inhibits tyrosinase activity to help brighten skin. Tyrosinase is an enzyme that controls melanin production.
A study from 2023 found 5% PAD combined with nicotinamide (a form of niacin) effectively reduced melanin production after 6 weeks.
Several studies from the 2010's also show PAD to be effective in alleviating symptoms of Rosacea.
Though this ingredient is considered a gentle active, higher amounts may result in irritation.
Unlike azelaic acid, this ingredient is water-soluble. This property makes it easier to formulate into skincare products.
Learn more about Potassium Azeloyl DiglycinateWater. 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!
