What it does:
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.

Lecithin 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.
Some other names for this ingredient include soy lecithin and deoiled soy lecithin.
