Why Sweet Sleep

For anyone who can’t switch off at night

Hollie created Sweet Sleep after months of broken nights with her 18 month old son. It is a soft, hand made body butter carrying magnesium chloride and calming botanicals.

Magnesium is a natural relaxant that helps soothe tension and tired muscles. You massage it in before bed, and it keeps working while you sleep.

We tested Sweet Sleep against the leading magnesium spray, on identical skin models under identical conditions.

9,388%

vs. leading spray

Greater magnesium absorption into skin surface layers.

4,442%

vs. baseline

More magnesium delivered than the control baseline.

  1. Keep a pot by your bed. Somewhere you will see it. The routine matters as much as the magnesium.
  2. Massage into the soles of your feet about 20 minutes before sleep. Shoulders, chest and legs work well too.
  3. Let it settle. No need to rinse. It absorbs as you wind down, and keeps working through the night.

Tocopherol (vitamin E)

A powerful antioxidant that locks in moisture and promotes skin healing.

Beeswax
