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. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

Glycolic Acid is arguably the most famous AHA with research to back up its benefits. Its main role is to peel the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and look more even.
Glycolic Acid has shown to boost collage production, a protein that helps skin stay firm. Overall, Glycolic Acid helps with improving uneven tone, rough patches of skin, fine lines, wrinkles, and sun damage. It also increases skin hydration by playing a role in creating molecules that create hyaluronic acid naturally.
When applying 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.
Recent studies have shown Glycolic Acid may protect the skin against UV damage. However, you should always wear SPF, especially when using exfoliants.

Hamamelis Virginiana Water is made used distilled parts of the witch hazel plant. The witch hazel plant is native to eastern North America.
The name 'Hamamelis Virginiana Water' refers to the distillation while the name 'Witch Hazel' is used when it is an active drug ingredient. Unless it is specified to be non-alcohol, many types of witch hazel are distilled in denatured alcohol.
Witch Hazel water is an astringent, anti-inflammatory, antioxidant, and antibacterial ingredient. The tannin in witch hazel has a drying effect when used on skin and constricts proteins. This helps minimize the look of large pores. The tannins present and the fragrance may be sensitizing. The catechins in witch hazel have anti-inflammatory properties while the gallic acid is antibacterial.
Indigenous groups have used witch hazel to help treat inflammation, which was then used by early settlers to North America.

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.

Salicylic Acid (also known as beta hydroxy acid or BHA) is one of the most well-known ingredients for treating skin that struggles with blackheads and acne. It helps to exfoliate both the skin's surface and pores, and also acts as an anti-inflammatory agent.
This multitasking property makes it a great ingredient for cleaning out pores, controlling oil production, and reducing inflammation.
Unlike AHAs which are water soluble, Salicylic Acid is oil soluble. This means that it's able to exfoliate the inside of pores and reduce blackheads.
Concentrations of 0.5-2% are recognized by the U.S. FDA as an over-the-counter topical acne product.
It can cause irritation and/or dryness if one's skin already has a compromised moisture barrier, so it's best to focus on repairing that before introducing a Salicylic Acid into your routine.
In general, Salicylic Acid is a great ingredient for oily acne-prone skin.
While salicylic acid does not increase sun-sensitivity, we still recommend wearing SPF.

Phospholipids are naturally found in our skin as they are the main component of cell membranes. Phospholipids have humectant, emollient, antioxidant properties.
The phospholipids in our skin can be naturally depleted. Replenishing the phospholipids in our skin can help hydrate your skin. Due to their hygroscopic nature, they act as humectants and emollients. Humectants draw moisture from the air to your skin, while emollients help trap moisture in. This ingredient is non-occlusive.
Studies show phospholipids display antioxidant activity and may help with reducing the signs of aging.
Phospholipids are complex lipids that contain glycerin, two fatty acids, and a phosphate group. Some foods that contain phospholipids include soybeans and milk. The phospholipids found in soy come from Lecithin. This ingredient can also be synthetically created.
Some types of phospholipids:

Ascorbyl Palmitate is created by combining pure Vitamin C and palmitic acid. It is an antioxidant and helps reduce hyperpigmentation.
Antioxidants help fight free-radical molecules, or molecules that may break down skin cells. Antioxdants help reduce signs of aging.
Ascorbyl Palmitate is a stable version of Vitamin C, meaning it does not disintegrate when exposed to sunlight. However, studies show it does not penetrate skin as well as pure Vitamin C.

Lecithin is a term for a group of substances found in plants, animals, and humans. They are made up of mixture of fatty acids. These fatty acids usually are a mixture of phosphoric acid's choline ester connected to stearic, oleic, and palmitic acids. Most lecithins are created from plant ingredients scuh as sunflower.
Lecithin is an emollient. Emollients help 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 help ingredients be better absorbed by the skin. The phospholipids in Lecithin can produce liposomes. Liposomes help other ingredients get through the skin barrier.

Sodium Benzoate is a preservative. It's used in both cosmetic and food products to inhibit the growth of mold and bacteria. It is typically produced synthetically.
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.
Sodium Benzoate 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.

In its pure form, Benzoic Acid looks like a white crystalline solid. It has slight solubility in water.
The name of Benzoic Acid comes from gum benzoin, which used to be the sole source of deriving this ingredient. Benzoic Acid is the most simple aromatic carboxylic acid.
