Learn more about BetaineLecithin is a term for a group of substances found in the cell membranes of plants, animals, and humans. They are made up of mixture of phospholipids.
This ingredient has emollient and emulsifying properties.
As an emollient, lecithen helps soften the skin and creates a barrier to keep moisture in.
As an emulsifier, it also helps prevent water and oil ingredients from separating. Lecithin can also help ingredients be better absorbed by the skin.
This is because the phospholipids in lecithin produce liposomes. Liposomes help other ingredients get through the skin barrier.
Depending on the source of this ingredient, lecithin may not be fungal acne safe. This is because some sources of lecithin come from soybean oil, which may feed the malassezia yeast that feeds fungal acne.
We recommend reaching out to the brand you are purchasing from to inquire about the source of their lecithin.

In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.
Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.
"Alkaline" refers to a high pH level. A low pH level would be considered acidic.

Naturium Multi-Bright Tranexamic Acid Treatment 5% 45 ingredients
Works well but...
With ingredients like tranexamic acid, kojic acid, and alpha-arbutin, this product is effective when it comes to combating dark spots and hyperpigmentation. I did notice that my post acne marks faded quicker when using this product HOWEVER this product always left a yellowish tint to my skin wherever I applied it. I suspect something in here oxidized (the kojic acid maybe?). This Show more

A lot of my post-acne marks have faded significantly after using this. Good texture, no pilling. No discernible smell.
So great for dark spots and is not irritating!
