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!

Lactic Acid is an AHA that is derived from fermenting lactose, a carbohydrate from milk. It removes the top layer of old and dead skin cells and helps increase cell turnover.

Benefits of Lactic Acid are that it can help to reduce large pores and reduce the effects of aging. Some potential downsides are that it can be bad for dry skin, cause irritation, worsen eczema, and worsen rosacea.

Not only does it help exfoliate the skin, it helps strengthen the skin's barrier. When applied, lactic acid helps the skin create ceramides.

Lactic acid is an over-the-counter chemical exfoliant that comes from the fermentation of lactose — a carbohydrate found in milk.

Legend has it that Cleopatra used to bathe in sour milk to help reduce wrinkles.

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

I patch tested this on my inner arm, and brown spots began to appear. I wasn't sure if this was the causal factor, so I tested it on my other arm. Same thing. Small brown spots began to appear where I placed the product. I couldn't find anything on line that explained this phenomenon, so I'm presuming it is too strong. If anyone has seen anything like this, please post a comment!
