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

Its main role is to remove the top layer of dead skin cells, allowing newer skin cells to emerge.
Specifically, AHAs work by breaking down the structural "glue" holding the old skin cells in place. Getting rid of the old skin cells allows skin to regenerate newer skin cells in its place. A build up of dead skin cells can lead to tired and dull looking skin.
Due to this, glycolic acid helps with:
Fun fact: Glycolic acid increases skin hydration by playing a role in creating molecules that create hyaluronic acid naturally.
When starting glycolic Acid, it is normal to feel slight stinging.
The pH value and concentration of glycolic acid play a role in the effectiveness of the product. Concentrations between 5-20% glycolic acid have been shown to be effective in clinical studies.
Recent studies have shown Glycolic Acid may protect the skin against UV damage. However, you should always wear SPF, especially when using exfoliants.

Learn more about Glycolic AcidSodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.
In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.
Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.
"Alkaline" refers to a high pH level. A low pH level would be considered acidic.

When applied, Gluconolactone has the same affect on skin as AHAs such as lactic acid. It helps dissolve the dead skin cells in the top layer of your skin. This improves texture and brightens the skin.
PHAs are more gentle than AHAs due to their larger structure. 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.
Gluconolactone has some interesting properties:
In a 2004 study, Gluconolactone was found to prevent UV damage in mouse skin cells and has not been found to increase sun sensitivity. However, we still recommend wearing SPF daily.
This ingredient is is an created by reacting gluconic acid with an alcohol.

This is a synthetic polymer. It helps improve the texture of products by adding thickness and gel-like feel.
It is also an emulsifer, meaning it prevents ingredients such as oil and water from separating. It also helps evenly disperse other ingredients.
Polyacrylate Crosspolymer-6 is a texture enhancer and pH adjuster.
It is be used to thicken water-based products and create a gel-texture with a velvet feel.
One manufacturer claims this ingredient to have a pH range of 2-8 and to be biodegradable.

Surfactants help reduce surface tension between ingredients with different states, such as liquids and solids. Emulsifiers help prevent oils and waters from separating.
Polysorbate 60 is sorbitol-based and created from the ethoxylation of sorbitan. Ethoxylation is a chemical reaction used to add ethylene oxide. Sorbitan is a the dehydrated version of sorbitol, a sugar found in fruits.
In this case, the 60 comes from reacting 60 units of ethylene oxide with sorbitan.
Polysorbates are commonly used in medicine and foods.

As an emulsifier, Sorbitan Isostearate prevents oils and water from separating.
Due to its isostearic acid base, it may not be safe for Malassezia or fungal acne.

brightens ur skin cz of the lemon enzyme and results within 1 week. i got rid of all active acne
I honestly didn't liked it at all. I consider my skin to be very resilient and tolerate really high concentrations of exfoliant ingredients, but this was a lot for a leave-in product. I could never use it more than twice a week so the results weren't as good as using another product with a lower concentration but on a daily basis. I ended up mixing it with my body moisturizer to help with KP Show more
