Tocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.
Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.
Another benefit is a bit of UV protection. Vitamin E helps reduce the damage caused by UVB rays. (It should not replace your sunscreen). Combining it with Vitamin C can decrease sunburned cells and hyperpigmentation after UV exposure.
You might have noticed Vitamin E + C often paired together. This is because it is great at stabilizing Vitamin C. Using the two together helps increase the effectiveness of both ingredients.
There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

Myristoyl Pentapeptide-17 isn't fungal acne safe and is a peptide.
Copper Tripeptide-1 is a peptide naturally found in body fluids. Peptides are building blocks for protein.
Studies show this ingredient tells our body to create more collagen and elastin. Collagen is a protein that makes connective tissue. Elastin is the protein responsible for giving our skin elasticity. Our bodies start to slow down collagen and elastin production with age.
Boosting collagen and elastin production can help create a healthier skin barrier. Having a healthy skin barrier means having firm and hydrated skin. It's a win-win situation!
This ingredient helps with scar healing. This is because it breaks down damaged collagen, the main component of scar tissue. It may also help with reducing sunspots, acne scars, and uneven skin tone.
On top of all this, Copper Tripeptide-1 is also an antioxidant. Antioxidants help the body fight off free-radicals. Free radicals are molecules that damage our cells, such as pollution and tobacco smoke.
More benefits: Copper Tripeptide-1 helps maintain tissues in blood vessels and promote natural hyaluronic acid in skin.

The antimicrobial property of Benzoic Acid helps elongate a product's shelf life. Its main role is to reduce fungi growth and is not found to be effective at fighting bacteria. Therefore Benzoic Acid is always added along with other preservatives.
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.
Benzoic Acid is naturally occuring in strawberries, mustard, cinnamon, and cloves. It has a slight scent but is not considered to be a fragrance.
Learn more about Benzoic AcidSodium 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.
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.
