Your questions, answered

WHAT DO THE DIFFERENT ABSORBENCY LEVELS MEAN?


Super Light: Holds up to 1 teaspoon, which is equal less than 1 regular tampons or 1 liner. It’s the perfect everyday underwear for light leaks and discharge, even when you’re not on your period.

Light: Holds up to 3 teaspoons, which is equal to 2 regular tampons or 1 pad, making them perfect for saving you from pesky drips, discharge, and lighter flows.

Moderate: Holds up to 5 teaspoons, which is equal to 3 regular tampons or 2 pads. Wear on moderate dates, or as extra defence on heavy days with our Period Cup. 

Heavy: Holds up to 7 teaspoons, which is equal to 4 regular tampons or 3 pads, making them great to wear on their own, day or night. 

HOW DOES LEAKPROOF PERIOD UNDERWEAR WORK?

Scarlet Period Underwear is designed to fit like normal underwear, and feature a multi-layered leak-proof technology that wicks away moisture, absorbs and contains fluid 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.

DO I NEED TO WEAR A CUP, TAMPON OR LINER TOO?

Depending on the absorbency level you choose and the heaviness of your flow, you can wear our period panties on their own or as backup protection along with a Period Cup or tampon. Take the time to explore a routine that works for you.

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!). Hang out to dry (the sunnier the better) or tumble dry on low - that’s it! 

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.

WHAT IS YOUR 30-DAY RISK-FREE TRIAL? 

This is a new way to period, and we understand fit may take a couple of goes to get into the swing of things. So, we have a 30-day risk-free trial to support you to find the perfect pair. Basically, if it’s your first time shopping with us and you’re not happy with your product, you may be eligible to claim a refund on that product, even if it’s used. Just email us at support@scarletperiod.com.

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. For extra ass-urance, make sure to whip out your trusty measuring tape. (Most likely stashed at the bottom of your junk drawer.) Make sure to check both our numeric or letter sizing so no confusion (ie. Our large is a 12). And when in doubt, feedback tells us better to size up.
