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.

Tranexamic Acid is best used for treating hyperpigmentation, discoloration, and melasma. It can also help build a stronger skin barrier.
Once applied, Tranexamic Acid starts decreasing inflammation from UV exposure. Tranexamic Acid also prevents our skin cells from meeting the pigment production cells.
Fun fact: Tranexamic Acid is also a medication used to reduce heavy bleeding.
This acid is derived from lysine, an amino acid.

SkinCeuticals Discoloration Defense Dark Spot Serum contains this as ingredient number 6.
Kojic acid comes from fungi and can also be from fermented foods.
Kojic Acid helps even out skin tone and reduce hyperpigmentation. It works by blocking tyrosine, an enzyme that starts the process of skin darkening.
Kojic Acid is antifungal and often used to treat fungal infections. Additionally, Kojic Acid can help fight bacteria with its antimicrobrial properties. A side effect may be treating acne caused by bacteria.
Kojic Acid has similar benefits to arbutin.

SkinCeuticals Discoloration Defense Dark Spot Serum contains this as ingredient number 9.
Caprylyl Glycol is a humectant and emollient, meaning it attracts and preserves moisture.
It is a common ingredient in many products, especially those designed to hydrate skin. The primary benefits are retaining moisture, skin softening, and promoting a healthy skin barrier.
Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.
This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.
