If you have gotten your period for the first time or are just tired of pads shifting at the worst possible time, period underwear can feel like a small but powerful upgrade. Instead of layering products or worrying about leaks, period panties for beginners work like regular underwear with built-in protection. All you have to do is just slip them on and get on with your day.
Mahina’s period underwear is designed to feel just like your favourite underwear while quietly doing the work. It features a 3-layer absorbent gusset that securely holds menstrual flow, ensuring you stay leak-free. For teens especially, this can make periods feel less overwhelming and more manageable. Here is how menstrual underwear for teens actually works:
- The top layer sits against your skin and pulls moisture away quickly, so you do not feel damp.
- The middle layer absorbs and locks in blood and discharge.
- The bottom layer acts as a leak-proof barrier that ensures you don’t stain your clothes.
Together, these layers give you protection that feels light, flexible, and secure, even on heavier days. Once you understand how it works, the next step is choosing the right pair for you.
The Two Things That Matter Most: Absorbency And Fit
Choosing The Right Absorbency
Your flow changes from day to day, and your protection should match that. One of the best things about period panties for beginners is that you can choose absorbency based on what your body needs, not the other way around.
Mahina’s period underwear for teens comes in 2 absorbency levels, each designed to support you for 12 hours.
1. Heavy absorbency
- Absorbs up to 40 ml
- Replaces around 4 pads, 5 tampons, or 2 menstrual cups in 12 hours
- Best for heavy daytime flow or when you want peace of mind
2. Super heavy absorbency
- Absorbs up to 50 ml
- Replaces around 5 pads, 7 tampons, or 2.5 menstrual cups in 12 hours
- Ideal for very heavy days or to sleep in
Choosing the right absorbency means fewer changes through the day, less worry about leaks or stains, and more freedom to focus on school, travel or rest without constant interruptions.
Choosing The Right Size
Fit matters more than you might think. The right size keeps the absorbent gusset in place so it can do its job properly.
To find your size:
- Use a measuring tape and stand in front of a mirror
- Measure around the widest part of your hips, not your waist
- Keep the tape snug but not tight, and parallel to the floor
- Match the number to Mahina’s size chart
- Use the Size Calculator on the product page if you want extra help
Mahina uses hip measurements because underwear sits on your hips, not your waist. Your period underwear should never feel tight or restrictive. When the size is right, it feels like a second skin.
How To Wash And Care For Your Period Underwear
Instead of using and throwing away several pads in one day, period underwear keeps things simple. You wear one pair, go about your day, and wash it when you’re done. No complicated steps, no extra stress. Once you know how to care for your menstrual underwear, it quickly becomes one of the easiest parts of your period routine.
