Your Questions, Answered

Why is everyone obsessed with magnesium?! And it’s not even oil?

Because it’s bloody amazing! Magnesium plays a vital role in over 300 biochemical processes in the body. It impacts energy, muscle function, and stress management. It can help with improved sleep, muscle relaxation, and overall well-being. 

And you're right, Sherlock. Magnesium oil is called "oil" due to its slick texture, although you’re spot on, it's not a true oil in a chemical sense. It’s still packed with buckets of benefits, plus an ultra-nourishing sensation on the skin.

Why am I spraying magnesium? Can’t I just take a supplement?

You sure can. However, we find that spraying magnesium on our bodies allows for direct absorption through the skin, bypassing our digestive systems and potential gastrointestinal issues associated with oral supplements. Spraying can offer quicker relief; however, the choice is totally up to you.

Why add extra extracts to a magnesium spray?

Because we reckon our magnesium sprays can (and should!) do more for us. Our soothing blend of tangerine, chamomile, rosemary, and arnica is the perfect cocktail for deep relaxation and refreshment. The extracts we’ve used have been tested to potentially help reduce inflammation, relax muscles, and boost skin health. 

How do I wash them?

After use, rinse them in cold water (we recommend in the shower) until they run clear. Then, machine wash in cold water with mild detergent (no bleach!). Try our Laundry Bag to safeguard them on laundry day. Then just hang out to dry (the sunnier the better) or tumble dry on low - that’s it!

TIP: If it’s your first wear, pop them in the washing machine with your next cold cycle - washing them before wearing activates their absorbency even more.

How do they work?

Scarlet Period Underwear is designed to fit like normal underwear and features multi-layered leak-proof technology that wicks away moisture, absorbs fluid, and contains it to keep you dry and protected. 

The built-in leak-proof technology is harder working than disposable pads which means it can safely hold more liquid and last for years not hours. Loved by all; you can read some reviews.

How do I pick the right size for me?

We get it, sizing for bottoms is anything but standardised. Which is why this size guide will help break it down for you. Make sure to check both our numeric and letter sizing so no confusion (ie. our large is a 12).

When in doubt, feedback tells us better to size up. Still confused? You can also email us for help at support@scarletperiod.com.
