Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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.

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.

Learn more about Lactic AcidLactobionic Acid is a PHA. PHAs are the gentle cousins to AHAS.
Like AHAs, they exfoliate the top layer of skin. Lactobionic acid also exhibits significant antioxidant activity.
PHAs are more gentle than AHAs due to their larger structure. This means they do not penetrate as deeply as AHAs and take a longer time to dissolve dead cells. Studies show PHAs do not cause as much irritation.
By removing dead skin cells, PHAs leave the skin brighter and with even-texture.

As an AHA, Mandelic Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and look more even.
Mandelic Acid may be an alternative to Glycolic Acid for those with sensitive skin.
Mandelic Acid may help reduce wrinkles, acne, and hyperpigmentation.

Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.

Salix Alba Bark Extract has often been described as salicylic acid's cousin. This is due to the salicin it contains. However, studies are limited showing salix alba bark to be an effective salicylic acid alternative.
Salicin does have anti-inflammatory and antioxidant properties. It has shown to decrease the formation of inflammatory mediators, such as tumor necrosis factor-α and nuclear factor-kappa B. Salicin also has a mildly exfoliating effect on the skin.
Several other components in salix alba bark extract also contain antioxidant properties, such as flavonoids and polyphenols. Antioxidants may help with anti-aging as they neutralize harmful free-radical molecules.
Willow Bark extract has been used for thousands of years. Ancient civilizations used white willow to help treat pain and fevers.

Both the US FDA and EU Health Committee have approved the use of sodium benzoate. In the US, levels of 0.1% (of the total product) are allowed.
Sodium benzoate works as a preservative by inhibiting the growth of bacteria inside of cells. It prevents the cell from fermenting a type of sugar using an enzyme called phosphofructokinase.
It is the salt of benzoic acid. Foods containing sodium benzoate include soda, salad dressings, condiments, fruit juices, wines, and snack foods.
Studies for using ascorbic acid and sodium benzoate in cosmetics are lacking, especially in skincare routines with multiple steps.
We always recommend speaking with a professional, such as a dermatologist, if you have any concerns.

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!
