I would recommend an egg and olive oil mask, all you need is one egg yolk and a tablespoon of olive oil.
The egg yolk contains water and fats that work to nourish and hydrate your skin whilst locking in moisture. The benefit of Olive oil is that it replenishes your skin without making it feel greasy. It also contains vitamin E, which lends greater elasticity to your skin.
The only problem with is that is can be quite runny, so I would recommend applying it with a brush. Alternatively, you could thicken up the mixture with a banana, this is recommended if you have extremely dry and/or flaky skin.
