Balea Waschcreme Gentle Washing Cream Versus ISANA Pflegendes Reinigungsöl

Older ingredient lists label it as "Octyl Stearate" and it turns up the most often in makeup products.

Industry data shows usage concentration goes up to ~40% in makeup and up to 10% in moisturizer or sunscreen.

Human repeat insult patch tests with a 25.9% lip gloss and 38.8% eyebrow pencil found no sensitization. A formula with 7.6% was also not an irritant, sensitizer, and was found to be non-phototoxic across 56, 19, and 27 subjects respectively.

True contact allergy to it is rare.

This ingredient shows up on a lot of "pore-clogging" lists but there's no real evidence behind that. It doesn't even have a comedogenic rating from an actual study; the numbers you'll find online come from blogs citing other blogs.

Ratings for other ingredients mostly come from a 1980s rabbit ear test. This test doesn't translate well to human skin or to real products because the ingredient sits at a much lower percentage.

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

The Malassezia yeast has been found to grow in the presence of fatty acids, fatty acid esters, and fatty alcohols with chains longer than 12 carbons. Ethylhexyl Stearate releases stearic acid, an 18-carbon chain, which is right inside that range; this ingredient may not be fungal acne safe.

As an emollient, it softens and hydrates skin by forming a thin barrier that locks in moisture.

Clinical studies have found it to be non-irritating and non-sensitizing. The CIR Expert Panel has evaluated the available safety data and concluded it is safe for topical use.

Because of the oleic acid content, this ingredient may not be fungal acne safe.

This ingredient does have a comedogenic rating of 3, but this doesn't mean a formula with this ingredient 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.

Topically applied tocopherol has been shown to protect against UV damage by ramping up the skin's own natural defense enzymes.

It also acts as a skin conditioning agent; some studies show that regular topical use can improve the skin's water-binding capacity over 2-4 weeks.

This ingredient is especially loved for being a team player. When combined with Vitamin C, the photoprotective effect of both ingredients roughly doubles and the combo also helps reduce UV-induced DNA damage.

This ingredient has some brightening potential but it's more of a prevention ingredient than spot-fader. Cell studies show it can slow down melanin production but it's worth noting that it's not the most powerful brightener out there.

In formulations, it also serves as a stabilizer that helps protect other oxidation-prone ingredients from degrading.

Concentrations usually range from 0.1-1% in most leave-on products.
