Ingredients Overview
Ingredients Explained
Aloe Barbadensis Leaf Extract is an extract of the leaves of the aloe, Aloe barbadensis, Liliaceae.
You may know Aloe to be a good sunburn reliever and inflammation reducer. This is because it contains many components that are known to help reduce irritation and itchiness. These include vitamins, amino acids, polysaccharides, and more. The high water content of aloe also helps give a cooling effect.
Aloe contains the antioxidants Vitamins A, C, and E. These vitamins neutralize free radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.
The aloe plant is naturally abundant in polysaccharides, a carbohydrate made of sugar molecules. Polysaccharides help hydrate your skin by mimicking your skin's natural carbohydrates.
As it is easily absorbed by the skin, aloe is a great moisturizer. It is both a humectant and emollient. Emollients help trap moisture in your skin, keeping your skin soft. Humectants draw water from the air to your skin.
Other components of aloe include sugars such as monosaccharides and polysaccharides, folic acid, choline, many common minerals such as calcium, fatty acids, amino acids, and Vitamin B12.
Aloe does not protect against UV rays, despite it soothing sunburns.
There are over 420 species of aloe but Aloe Barbadensis is the most commonly used for topical products.
Learn more about Aloe Barbadensis Leaf ExtractPropanediol 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.
Learn more about PropanediolArbutin is derived from the bearberry plant. It helps even out skin tone and reduce hyperpigmentation.
Arbutin blocks tyrosinase, an enzyme that starts the process of skin darkening. When applied to the skin, Arbutin works at a slow pace. This can make it less irritating than similar ingredients.
Arbutin has similar benefits to Kojic Acid
Learn more about ArbutinNiacinamide 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.
Learn more about Niacinamide1,2-Hexanediol is a multi-tasker ingredient. It acts as a preservative to increase shelf-life and can aid other preservatives in preventing microbe growth. 1,2-Hexanediol also helps the skin retain moisture as a humectant.
In products that are water-based, this ingredient can help stabilize perfumes and fragrances. It can also help make the texture of products softer and more smooth.
Hydroquinone is used to treat hyperpigmentation, acne scars, and age spots.
This ingredient is a known skin sensitizer and is banned in the EU. In the US, this ingredient is not allowed for over-the-counter sale.
According to the FDA, hydroquinone may cause permanent skin discoloration, rashes, and facial swelling.
Be sure to use this ingredient as prescribed by your doctor. Wearing sunscreen is also a must (you should be wearing sunscreen anyway!).
Hydroquinone works by decreasing the melanocytes in your skin. Melanocytes are cells that create melanin.
Gentle reminder that all skin tones are beautiful!
Learn more about HydroquinoneCitric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).
If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.
As an AHA, Citric 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.

Learn more about Citric AcidSodium Citrate is the sodium salts of citric acid. In skincare, it is used to alter pH levels and acts as a preservative.
Sodium Citrate helps maintain the pH of a product. Normal pH level of skin is slightly acidic (~4.75-5.5). The acidity of our skin is maintained by our glands and skin biome. Being slightly acidic allows our skin to create an "acid mantle". This acid mantle is a thin barrier that protects our skin from bacteria and contaminants.
Sodium Citrate is a chelating agent. It neutralizes metal ions from water and prevents them from binding to other ingredients. This ensures the other ingredients will not be altered.
Learn more about Sodium CitrateSodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.
Sodium Hyaluronate is naturally occurring in our bodies and is mostly found in eye fluid and joints.
These are some other common types of Hyaluronic Acid:
Learn more about Sodium HyaluronateSalicylic 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.

Learn more about Salicylic AcidKojic 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.
Learn more about Kojic AcidLactic 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.

Learn more about Lactic AcidHamamelis Virginiana Leaf Extract comes from the witch hazel plant.
Witch Hazel 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.
Learn more about Hamamelis Virginiana Leaf ExtractRosemary extract has antioxidant, anti-inflammatory, anti-bacterial, and astringent properties.
This ingredient has a natural fragrance due its small component of rosemary oil. The antioxidant properties from its rosmarinic acid, flavone, and phenolic acids.
