Ingredients Explained
Hydroquinone is used to treat hyperpigmentation, acne scars, and age spots.
It works by decreasing the melanocytes in your skin. Melanocytes are cells that create melanin (the color pigment in skin).
Be sure to use this ingredient as prescribed by your doctor. Wearing sunscreen is also a must (you should be wearing sunscreen anyway!).
Most hydroquinone prescriptions are not to be used for longer than 3 months. Long term usage can cause ochronosis, or a condition in which the skin darkens more than before.
This ingredient is banned in the EU for being skin sensitizer. In the US, this ingredient is not allowed for over-the-counter sale.
However, it is still possible to get hydroquinone in the EU, US, Canada, Australia, and Japan from a doctor's prescription.
There is no known research backing this ingredient to be carcinogenic in humans.

Gentle reminder that all skin tones are beautiful!

Glyceryl Stearate is used to stabilize the mixing of water and oil ingredients. By preventing these ingredients from separating, it can help elongate shelf life. It can also help thicken the product's texture.
As an emollient, it helps soften skin and supports barrier-replenishing ingredients.
In cosmetics, Glyceryl Stearate is often made from vegetable oils or synthetically produced. The human body also creates Glyceryl Stearate naturally.

Like other oils, Paraffinum Liquidum has emollient properties. Emollients help soothe and soften the skin. By creating a barrier to trap moisture within, emollients help keep your skin hydrated.
Paraffinum Liquidum does not irritate the skin and is non-comedogenic. However, this ingredient may not work well for those with oily skin or fungal acne.
If you have concerns about using this ingredient in your routine, we recommend speaking with a professional.

This ingredient may not be Malassezia folliculitis, or fungal-acne safe.

Another role of this ingredient is preventing a product from melting or freezing. Propylene glycol also adds antimicrobrial properties to a product, elongating product lifespan.
This ingredient is considered an organic alcohol and commonly added into both cosmetics and foods.
Those with sensitive skin or conditions may deliver a rash when using this ingredient.
Learn more about Propylene GlycolPropylparaben is a preservative and is a paraben with antifungal and antimicrobial properties.
This ingredient can be naturally found in plants and insects, but most of it is synthetically manufactured for human use. In cosmetics, it is usually created by reacting para-aminobenzoic acid and propanol (an alcohol).
You can usually find this ingredient in water-based products.
Parabens have come under controversy due to the claim they are hormone disruptors. Studies show conflicting results. We recommend speaking with a professional if you have any concerns.
Propylparaben is commonly found in food, medicine, and cosmetics.

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. If you see this, drink a glass of water. Stay hydrated!

Squalane is an emollient that helps the skin hold onto moisture. It's an oily liquid that occurs naturally in certain types of fish and plant oils.
Because squalane boosts hydration in the skin, it also comes with plenty of benefits: it is an antioxidant and can help fight free radicals and skin damage. Squalane is also found to have a detoxifying effect when applied.
Squalane comes from squalene, which occurs naturally within the sebum of our skin. It is one of the oils our skin produces to keep itself hydrated. Squalane is the hydrogenated version of squalene and has a longer shelf life.
Research shows that squalane is non-irritating (even at 100% concentration).
In general, it's a fantastic ingredient. It does a great job at hydrating the skin, and it's suitable for those with sensitive skin.
The source of squalane may impact malassezia / fungal acne. This is because olive oil derived squalane can contain impurities such as fatty acids and plant waxes. Sugarcane derived squalane is recommended for anyone with malassezia concerns.
Is squalane vegan?
This depends on the source. Squalane can be derived from both plants and animals. Most squalane used in skincare comes from plants.
Please note: the source of squalane is only known if disclosed by the brand. We recommend reaching out to the brand if you have any questions about their squalane.

As an emollient, stearic acid helps soften skin. It aids the skin's protective barrier by preventing water loss. It also provides a gentle cleansing effect without stripping away natural oils.
Stearic acid may also be used to enhance the texture of products. It can add volume and stabilize ingredients such as water and oil. This can help water and oil ingredients from separating.
Sources of stearic acid include animal or vegetable fats/oils such as coconut or shea. It can be naturally found in butter, cocoa butter, shea butter, vegetable fats, and animal tallow.
This ingredient may not be Malassezia folliculitis, or fungal-acne safe.
