Ceramide NP is a type of ceramide.

Ceramides are intercellular lipids naturally found in our skin that bonds dead skin cells together to create a barrier. They are known for their ability to hold water and thus are a great ingredient for dry skin.

Ceramides are an important building block for our skin barrier. A stronger barrier helps the skin look more firm and hydrated. By bolstering the skin ceramides act as a barrier against irritating ingredients. This can help with inflammation as well.

If you would like to eat ceramides, sweet potatoes contain a small amount.

Phytosphingosine is a phospholipid naturally found in our skin. It helps moisturize, soothe, and protect skin.

Phytosphingosine is already present in our skin. On our skin, it is a building block for ceramides.

Phytosphingosine tells our skin to increase its natural moisturizing factor (NMF). The NMF is responsible for hydration, a strong barrier, and plasticity. Our NMF decreases with age. Increasing NMF leads to more healthy and hydrated skin.

Studies show products formulated with NMF ingredients help strengthen our skin's barrier. Having a healthy skin barrier reduces irritation and increases hydration. Our skin barrier is responsible for having plump and firm skin. It also helps protect our skin against infection, allergies, and inflammation.

Phytosphingosine is also abundant in plants and fungi.

It does feel nice on the lips, but keep in mind that it's mostly a glorified, really overpriced chapstick. You could just use chapstick. A slightly heavier chapstick will do the exact same thing--my lips did not feel any different the next morning. Personally just like to use a Burts Bees in the PM and it does exactly the same thing, if not better.

It does an amazing job at hydrating my dry-prone lips overnight, but the price is expensive for the quantity.
