Anyone knows the importance of sleep, let alone beauty sleep. Here are some essentials that celebrities use to keep looking gorgeous as they go to bed.

Lucy Watson knows the importance of a good complexion. The "Made In Chelsea" star swears by Witch Skincare Overnight Clearing Serum to retain flawless skin.

"If I have a spot or blemish appearing I will always use this," she says about the product. The serum gives the skin essential vitamins and moisturizing effects even when snoozing.

Many stars have been using The Dr. Organic Snail Gel Cream, and singer Ashley Roberts is no exception. The Aloe Vera extract and Shea butter infused cream both "tones and hydrates lackluster skin," as said by Reveal UK. The product also has anti-aging properties, perfect in attaining that youthful glow.

Numerous celebs have also been spotted using Ciaté products as part of their regimen before getting beauty sleep. The Ciate Knight In Shining Armour Overnight Nail Mask helps create stronger nails.

The formula helps avoid nail chipping, nail breakage, and flaking. The polish can be easily washed off in the morning after waking up from a deep slumber.

The Manuka Doctor ApiNourish Restoring Night Cream is a lifesaver for those with inevitable dry spots. The cream is actually Caroline Flack's go-to moisturizer.

"I make my skincare routine as simple as possible with this cream. I try to get plenty of sleep and I always cleanse, tone and moisturize before heading off to bed," she shared.

"The Only Way Is Essex" reality star Georgia Kousoulou uses coco butter oil to help her tone her amazing body. "I use this on my legs and then pat a little bit on my bottom," she said.

"I notice the cellulite and dimples on the back of my legs disappearing a little more every single day," Kousoulou added. The Body Shop Cocoa Butter Beautifying Oil also has great hydration properties for the skin.
