Ci 77891 is commonly found in sunscreens due to its ability to block UV rays.

Dimethicone comes in different viscosities:

Depending on the viscosity, dimethicone has different properties.

Ingredients lists don't always show which type is used, so we recommend reaching out to the brand if you have questions about the viscosity.

This ingredient is unlikely to cause irritation because it does not get absorbed into skin. However, people with silicone allergies should be careful about using this ingredient.

Note: Dimethicone may contribute to pilling. This is because it is not oil or water soluble, so pilling may occur when layered with products. When mixed with heavy oils in a formula, the outcome is also quite greasy.

There's no published concentration use from surveys so the best available numbers are supplier guidance: 5-10% for loose powders and 2-5% for creamy cosmetics + pressed powder binding.

The CIR Expert Panel reviewed Magnesium Myristate as part of its assessment of myristic acid and its salts and esters, and concluded the whole group is safe as used in cosmetics.

In human studies, Myristic Acid was non-irritating up to 50% and 100% Magnesium Stearate was non-irritating and non-corrosive on skin and non-irritating to the eye.

There are no published contact allergy case reports for this ingredient so allergy risk is low, but not zero for any ingredient.

There is no comedogenic data for Magnesum Myristate. The comedogenic ratings that circulate for "myristates" come from Isopropyl Myristate which is a structurally different ester.

The rabbit-ear models those comedogenic ratings come from have been shown to be unreliable for predicting whether a finished product will clog pores.

Human testing has proved that any finished product with a comedogenic ingredient won't automatically make you break out; it really comes down to concentration, formula, and your skin.

Some people still find it breaks them out. So if that's you, definitely trust your skin.

This ingredient is often coated with metal oxides like titanium dioxide. Trace amounts of heavy metals may be found in mica, but these metals are not harmful in our personal products.

Mica has been used since prehistoric times throughout the world. Ancient Egyptian, Indian, Greek, Roman, Aztec, and Chinese civilizations have used mica.

You'll likely see this in many BHA products because this is the go-to solvent for salicylic acid.

This ingredient is typically used at levels between 2-20%.

Regarding fungal acne:
In 2019, this ingredient was tested against multiple Malassezia species (the yeast that causes fungal acne) and showed no growth.

Despite being a "stearate", it has a lightweight, cushiony, and non-greasy slip.

This ingredient has shown no adverse effects in testing and is deemed safe in cosmetics at current use levels.

Typical concentrations range from 0.7-23%.

Because it is made of C-18 fatty acids (like stearic acid), this ingredient may not be fungal acne safe.

It's a well-vetted ingredient for safety and does not penetrate into skin due to its large molecule size.

Because it's a long-chain fatty acid ester, this ingredient may not be fungal acne or Malassezia safe.

The unique structure of silica enhances the spreadability and adds smoothness, making it a great texture enhancer.

It is also used as an active carrier, emulsifier, and mattifier due to its ability to absorb excess oil.

In some products, tiny microneedles called spicules are made from silica or hydrolyzed sponge. When you rub them in, they lightly polish away dead skin layers and enhance the penetration of active ingredients.

It is considered non-irritating on the skin.
