COSRX Low pH First Cleansing Milk Gel Versus Troiareuke ACSEN Oil Cut Cleansing

It's pretty compatible with most ingredients, but just sure to space out enzyme products with strong acids/retinoids to avoid over-doing it.

Maximum reported concentration is around 0.1% and most leave-on products use just 0.05%. If you see higher figures like 5-10%, this is usually the pre-diluted material from raw extract suppliers.

This ingredient has an assuring safety record and there's a lack of clinical case reports of dermatitis from using it.

The only caveat is allergy: patch test if you have a papaya or latex-fruit allergy.

On top of that, this ingredient can counteract the effects of hard water by binding to the minerals in it.

One thing worth knowing is that Disodium EDTA has been shown to be a mild penetration enhancer. It can help other ingredients absorb into skin more effectively which can be a double-edged sword (great for actives, but can also make the active too strong if you have sensitive skin).

Clinical patch testing showed no significant skin irritation at typical use concentrations and minimal dermal absorption.

You'll most likely see this ingredient near the end of an ingredient list. It's typically found in concentrations less than 1%.

Industry survey data shows use concentrations from about 0.05% up to 97%, with leave-on products typically sitting closer to 1-12%.

This exact ingredient doesn't have documented case reports but closely related PEG-7 fatty acid esters do; there's a published case of contact dermatitis from PEG-7 hydrogenated castor oil in a sunscreen, and another from PEG-7 monooleate.

A true allergy is possible but appears uncommon. Just be sure to patch test if you are unsure.

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 breaks down fatty acid esters in the C11-24 range. Since this ingredient is an ester of olive oil's fatty acids (mostly C18), it may not be fungal acne safe.

This is why "gentle" and "moisturizing" cleansers feel less stripping than basic ones.

Typical concentrations range from 1-10% and it has a solid safety record. The CIR Expert Panel has concluded this ingredient to be safe at concentrations up to 10% in leave-on products.

Dermal application tests at 50% also did not produce irritation in two studies.

This ingredient may not be fungal acne safe and in vitro studies have shown Malassezia can metabolize it.

You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
