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 is decent but you gotta be careful with it if you’re sensitive. I was dealing with some intense inflammatory acne after messing up my skin barrier. My skin seemed to be on the mend so I tried this thinking my skin wouldn’t still be so sensitive and it would help clear up the remaining congestion left behind by my crazy breakout, but I think I should have waited a little longer or only used it Show more

It’s much gentler than the ordinary’s version while still being effective. Maybe a bit less of a dramatic change but my skin tolerates it much better.

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
