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

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.

This was THE BEST toner I’ve ever used in my entire life hands down. It brightens the skin, smoothes and gives a youthful look, exfoliates and completely gets rid of dark spots and you notice a difference after not too long. By month 2 my skin was completely perfect like I’d never had dark spots or got acne or had dull uneven skin. Where I’m located I can’t consistently purchase it even trying to Show more

Texture: Like water. Absorbed easily.
Scent: No scent
Performance: BHA+AZ good for treating acne/blackhead.
Pros: Multi function serum.
Cons: Been reformulated but discontinued (until further clarification with authorities). AZ is restricted in local skincare products, but reformulated one is using AZ derivative. Confusion on product naming.
WRP/WNRP: WRP if relaunch.
