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 AcidMalic Acid is an acid with both AHA and BHA properties, but is considered an AHA because its AHA properties are stronger.
Like other AHAs, it removes the top layer of old and dead skin to reveal the newer layer underneath. It also helps with improving fine lines, wrinkles, skin tone, skin texture, and acne blemishes.
Due to its exfoliating properties, you should wear SPF when using Malic Acid.
Fun fact: The word "Malic" comes from the word "Malum". In Latin, "Malum" means apple. This ingredient is often derived from unripe fruit.

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.

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 AcidPhenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.
It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Lecithin is a term for a group of substances found in the cell membranes of plants, animals, and humans. They are made up of mixture of phospholipids.
This ingredient has emollient and emulsifying properties.
As an emollient, lecithen helps soften the skin and creates a barrier to keep moisture in.
As an emulsifier, it also helps prevent water and oil ingredients from separating. Lecithin can also help ingredients be better absorbed by the skin.
This is because the phospholipids in lecithin produce liposomes. Liposomes help other ingredients get through the skin barrier.
Depending on the source of this ingredient, lecithin may not be fungal acne safe. This is because some sources of lecithin come from soybean oil, which may feed the malassezia yeast that feeds fungal acne.
We recommend reaching out to the brand you are purchasing from to inquire about the source of their lecithin.
