Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

BHT
Masking, Antioxidant

BHT is a synthetic antioxidant and preservative.

As an antioxidant, it helps your body fight off free-radicals. Free-radicals are molecules that may damage your skin cells.

As a preservative, it is used to stabilize products and prevent them from degrading. Specifically, BHT prevents degradation from oxidation.

The concerns related to BHT come from oral studies; this ingredient is currently allowed for use by both the FDA and EU.

However, it was recently restricted for use in the UK as of April 2024.

Cetyl Alcohol is a fatty alcohol. Fatty Alcohols are most often used as an emollient or to thicken a product.

Its main roles are:

Though it has "alcohol" in the name, it is not related to denatured alcohol or ethyl alcohol.

The FDA allows products labeled "alcohol-free" to have fatty alcohols.

Emollient, Emulsifying

Glyceryl Stearate is a mix of glycerin and stearic acid.

It 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.

This ingredient may not be fungal-acne safe

Fun fact: The human body also creates Glyceryl Stearate naturally.

Stabilising

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!

Emollient, Solvent

Isododecane is a fragrance, emollient, and solvent.

As an emollient, it helps your skin stay soft and hydrated. Emollients help trap moisture into your skin.

Isododecane's role as a solvent makes it a great texture enhancer. It spreads smoothly on skin and does not leave a sticky feeling behind. Isododecane also helps prevent color transfer in makeup products.

Isododecane is not absorbed into skin.

PEG-75 Stearate isn't fungal acne safe.

Preservative

Sorbic Acid is a preservative. It is the most commonly used food preservative in the world.

Sorbic Acid is a natural antibiotic and highly effective at preventing the growth of fungus. It is less effective against bacteria.

Potassium Sorbate, another commonly-used preservative, is the potassium salt of Sorbic Acid.

Sorbic Acid may worsen eczema. We recommend speaking with a professional if you have any concerns.

Potassium sorbate and sorbic acid can be found in baked goods, cheeses, dried meats, dried fruit, ice cream, pickles, wine, yogurt, and more.
