La Roche-Posay Toleriane Purifying Foaming Cream CleanserIngredients explained
Good old water, aka H2O. The most common skincare ingredient of all. You can usually find it right in the very first spot of the ingredient list, meaning it’s the biggest thing out of all the stuff that makes up the product.
It’s mainly a solvent for ingredients that do not like to dissolve in oils but rather in water.
Once inside the skin, it hydrates, but not from the outside - putting pure water on the skin (hello long baths!) is drying.
One more thing: the water used in cosmetics is purified and deionized (it means that almost all of the mineral ions inside it is removed). Like this, the products can stay more stable over time.
- A natural moisturizer that’s also in our skin
- A super common, safe, effective and cheap molecule used for more than 50 years
- Not only a simple moisturizer but knows much more: keeps the skin lipids between our skin cells in a healthy (liquid crystal) state, protects against irritation, helps to restore barrier
- Effective from as low as 3% with even more benefits at higher concentrations up to 20-40% (around 10% is a good usability-effectiveness sweet spot)
- High-glycerin moisturizers are awesome for treating severely dry skin
A 14 carbon length fatty acid that can be naturally found in nutmeg, palm kernel oil, coconut oil and butter fat. It's used as a foam building cleansing agent. Paula Begoun writes that it can be a bit drying to the skin.
It's a very alkaline stuff that helps to set the pH of the cosmetic formula to be just right. It's similar to the more often used sodium hydroxide and pretty much the same of what we wrote there applies here too.
An oily kind of ingredient that can magically blend with water all by itself. This is called self-emulsifying and SE in its name stands for that.
The difference between "normal" Glyceryl Stearate and this guy is that the SE grade contains a small amount of water-loving soap molecules, such as sodium stearate. This increases Glyceryl Stearate's affinity for water and gives it stronger emulsifying abilities.
Other than that, it’s a nice emollient that gives a smooth and soft appearance to the skin.

A common multi-tasker fatty acid. It makes your skin feel nice and smooth (emollient), gives body to cream type products and helps to stabilize water and oil mixes (aka emulsions).
A 12 carbon length fatty acid that can be found naturally in coconut milk, coconut oil, laurel oil, and palm kernel oil. It's also in breast milk. As a skincare ingredient, it can be used as an emulsifier or as a cleansing agent.
What's more, there is emerging research about lauric acid being a good anti-acne ingredient. A 2009 study found that the lowest concentration to prevent evil acne-causing P. acnes growth of lauric acid is over 15 times lower than that of gold standard anti-acne ingredient benzoyl peroxide.
Though the studies are only in-vitro (made in the lab, not on real people), and it also has a high comedogenicity index, it might be worth a try if you are prone to inflamed acne (the type that's caused by P. acnes bacteria).
A fatty acid that can be found naturally in the skin. In fact, it's the most common saturated fatty acid found in animals and plants.
As for skincare, it can make the skin feel nice and smooth in moisturizers (emollient) or it can act as a foam building cleansing agent in cleansers. It's also a very popular ingredient in shaving foams.
A vegetable origin (coconut/palm kernel oil, glucose) cleansing agent that gives moderate to high stable foam. It's also biodegradable and mild to the skin.
