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!

Niacinamide has emerged as an all-star ingredient due to its many benefits.
It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.
Other benefits include smoothing wrinkles and minimizing redness.
The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.
When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.
Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

Undefined Beauty R&R Sun Serum SPF 50 PA++++ contains this as ingredient number 9.
Propanediol helps absorb ingredients into your skin, boosting their benefits. It can act as an emollient, making your skin softer. Propanediol can help products last longer by boosting the properties of preservatives within the formulation.
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.

Undefined Beauty R&R Sun Serum SPF 50 PA++++ contains this as ingredient number 4.
Caprylic/Capric Triglyceride is an emollient, solvent, and texture enhancer. It is considered a skin-softener by helping the skin prevent moisture loss.
Within a product, Caprylic Triglyceride can thicken the product and make spreadability easier by dissolving clumping compounds. An added benefit of Caprylic Triglyceride is its antioxidant properties.
Caprylic Triglyceride is made by combining glycerin with coconut oil, forming a clear liquid. Caprylic Triglyceride has not been found to be toxic for human use in concentrations under 50%.
While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this.

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.

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.
