Here are some excellent occlusives that will help keep your skin hydrated too.

To provide extra protection, resist the urge to rub them in – allow them to sit on top of the skin in a thin layer to form a protective seal. Try applying them just before bed so they can work their healing magic while you sleep.
Shea Butter

Extracted from the nuts of the Vitellaria paradoxa tree, shea butter has been used for centuries by the peoples of West Africa to nourish the skin in arid climes. It works as both a moisturizing emollient and a protective occlusive.

Shea butter is a complex fat that is enriched with calcium, iron, magnesium, manganese, zinc, copper, potassium, fatty acids, and vitamin E. In addition to its anti-inflammatory properties, it also contains valuable antioxidants like Gallic acid and several catechin compounds. This blend of fatty acids, nutrients, and phenolics helps hydrate dry skin. Though it is a butter, it melts when applied to the skin and forms a non-greasy and breathable barrier against the elements.
Long used medicinally, the comfrey plant (Symphytum officinale) possesses plenty of beneficial properties for the skin.

The roots, in particular, contain small amounts of allantoin – a powerful organic compound that soothes and heals the dermis. Akin to a natural peel, it also has keratolytic properties that aid in shedding the outer layer of the skin while boosting healthy tissue formation.

Another interesting aspect of allantoin is its ability to absorb moisture when it’s applied to the skin. When added to a liquid, it becomes a lightweight occlusive that is perfect for people with sensitive skin.
