Ingredients Explained

These ingredients are found in both products.

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

Skin Conditioning, UV Absorber, UV Filter

You might know this ingredient as Tinosorb S or Bemotrizinol. It is a UV filter that covers both UVA and UVB rays.

This ingredient has two peak UV absorption peaks ( 310 and 340 nm) and is able to absorb both UV-A and UV-B rays. This ingredient works by preventing UV rays from reaching and damaging your skin.

On top of that - it is highly photostable and helps prevent the photodegration of other sunscreen ingredients such as avobenzone.

Tinosorb S is allowed in the EU, Australia, and Asia. It is close to being approved by the FDA and we'll hopefully get this ingredient in the U.S. by late 2025.

Fun fact: Tinosorb S is the most effective UV absorber at maximum concentration (measured by SPF) permitted in the EU.

This ingredient is oil-soluble, so your oil-cleansers will take this right off at night.

UV Absorber, UV Filter

Also known as Avobenzone, this ingredient is a chemical sunscreen filter that provides protection in the UV-A range.

Avobenzone is globally approved and is the most commonly used UV-A filter in the world.

Studies have found that avobenzone becomes ineffective when exposed to UV light (it is not photostable; meaning that it breaks down in sunlight). Because of this, formulations that include avobenzone will usually contain stabilizers such as octocrylene.

However, some modern formulations (looking at you, EU!) are able to stabilize avobenzone by coating the molecules.

Avobenzone does not protect against the UV-B range, so it's important to check that the sunscreen you're using contains other UV filters that do!

The highest concentration of avobenzone permitted is 3% in the US, and 5% in the EU.

Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) is a chemical UV-A absorber. It is formulated for high UVA protection (320-400 nm).

DHHB is well-liked for:

DHHB has been approved by the EU, Japan, Taiwan, and South America for use up to 10%. Unfortunately, it has not been approved for use in the US or Canada due to slow regulatory processes.

This ingredient is soluble in oils, fats, and lipids.

Emollient, Emulsifying, Skin Conditioning

Hydrogenated Castor Oil is created by adding hydrogen to castor oil. This helps stabilize the castor oil and raises the melting point. At room temperature, hydrogenated castor oil is solid.

Castor Oil helps moisturize the skin. It is rich in a fatty acid called ricinoleic acid. This fatty acid helps prevent moisture loss on the skin. This helps keep your skin soft and hydrated. Ricinoleic acid also has anti-inflammatory and pain reducing properties.

As a wax-like substance, Hydrogenated Castor Oil acts as an emollient. Emollients help keep your skin stay soft and smooth by creating a barrier. This barrier helps trap moisture.

Hydrogenated Castor Oil may not be fungal-acne safe. We recommend speaking with a professional.
