Silk provides hydrating, anti-aging, acne-fighting and sensitive skin benefits to help your skin glow.

Hydrates and Rejuvenates

Sleek silk pillowcases are crafted from long woven fibres that helps your skin to remain hydrated overnight, by not rubbing or wicking away your skin's natural hydration. Cotton pillowcases suck moisture and skincare products from your skin. Sleek silk helps you to retain your skin's natural moisture, and keep friction and abrasion low, keeping your skin looking smooth and youthful.

Prevents Signs of Aging

Friction whilst we sleep can lead to premature aging and uneven texture. We use our pillowcases 8 hours a day! Silk glides smoothly over your skin, preventing the formation of new fine lines and wrinkles as you sleep, so you wake up radiant.

Fights Acne and Eczema

The natural anti-microbial properties of Sleek silk help prevent bacterial growth that can lead to acne and breakouts. The smooth surface of silk also minimizes friction and irritation that can worsen breakouts or irritation from eczema.

Soothes Sensitive Skin

Sleek silk is naturally hypoallergenic. Silk is free of harsh irritants and repels allergenic particles, making it ideal for sensitive conditions like eczema and psoriasis.
Silk is not a quick fix, but is effective as a long term solution to irritable skin conditions.

Sleek silk delivers multiple benefits for your healthiest, shiniest hair ever. It boosts shine, prevents frizz and damage, and reduces tangles.

Boosts Hydration and Shine

Silk doesn't absorb moisture like cotton does. This allows your hair to retain its natural oils and hydration. Your hair stays healthy, soft and shiny. Stay Sleek!

Reduces Friction and Splits

Silk fibres deliver nearly 50% less friction compared to cotton pillowcases. This friction reduction results in less frizz, hair breakage, split ends, and hair loss overnight. Over time, the benefits accumulate.

Prevents Tangles and Knots

The smooth and gentle texture of silk prevents hair tangles and knots during sleep. Wake up feeling refreshed and looking fresher. Sleek dreams!

You should follow the washing instructions on the label attached to the inside of the pillowcase. These are as below:

• We recommend hand washing gently in cool water.
  
• Dry clean safe.
  
• Machine wash safe. Use a delicate wash cycle no higher than 30°C. Use a wash bag.
  
• Do not tumble dry or wring dry by hand.
  
• To dry, lay flat on a dry towel out of direct sunlight.
  
• Do not use fabric softeners.
  
• Use non-biological colour friendly washing detergent.

We recommend washing your pillowcase each week, or at least every fortnight.

Ideally, you will have 2 or more sets that you can regularly rotate.

Here's a link to our article on this subject: How often should I wash a silk pillowcase?

We recommend washing your pillowcase before using it for the first time.

This will help remove any creasing during transit and ensure your Sleek pillowcase is as fresh as it can be for your skin.

However, your Sleek silk pillowcase will be ready to use as soon as it's unpacked!
