Vol. 24 | How to choose absorbent pads and absorbent underwear | Comparing by flow and usage scenario

Nov 12, 2026

Conclusion: Rather than one being superior to the other, the right choice between absorbent napkins and absorbent period underwear depends on "ease of replacement," "absorbency," and "the situation in which they are used." Absorbent napkins are a good candidate for those who want to change frequently while out, while absorbent underwear is better for those who want to avoid changing clothes. For heavy flow days or extended periods of time, be sure to check the product's indicated absorbency and replacement timing.

How to choose absorbent napkins/absorbent period underwear: Compare your menstrual flow, duration of wear, skin comfort, and the burden of washing and carrying them, then choose the period products that you can use comfortably and consistently.

How to choose absorbent napkins

1. Consider whether you can change them first

If you have easy access to a restroom at work or school, absorbent napkins are an easy-to-manage option. For days with long outings, check if you can carry spares, if they are individually wrapped, and if they are easy to dispose of.

2. Check the skin-contact side and size

Check the material of the surface that touches your skin, the presence of wings, front-to-back length, and thickness. If you experience itching, redness, or stinging, stop use and re-evaluate other factors like detergents or fragrances that may be causing irritation.

3. Choose an absorbency type that matches your flow

"Daytime," "Heavy flow," and "Nighttime" labels are just guidelines. If they don't match your flow and wear time, make adjustments by changing earlier or combining with other types.

How to choose absorbent period underwear

1. Think of absorbency in terms of "the time you can safely wear them"

The ml rating on product pages is a general guide per product. On heavy days, during sleep, or long trips, do not judge based solely on maximum capacity; check if you can change during times when leaks are a concern.

2. Fit and crotch design

Look at your actual waist and hip measurements and choose a size that isn't too tight and won't slip during movement. Check the front and back coverage, crotch thickness, and breathability like mesh materials.

3. Confirm the burden of washing and drying

Pre-washing requirements, use of a laundry net, and tumble-drying compatibility vary by product. Consider the ease of maintenance, including whether you have spares and the time it takes for them to dry.

FAQ | Common Questions

Q. Can I use absorbent napkins and absorbent underwear together?

A. Depending on the product instructions, combining them can be a way to increase peace of mind. However, if it increases stuffiness or tightness, don't force it and try it for a short time to see how it feels.

Q. How many hours can I wear absorbent underwear?

A. There is no set time. It varies based on flow, product absorbency, activity level, and the season; check the product labeling and replace or wash before you feel dampness or discomfort.

Q. Are menstrual cups or discs more convenient?

A. Convenience is subjective. Compare ease of insertion, changing locations, and the hassle of cleaning and storage to choose what is easiest for you to continue using. You can also refer to the difference between menstrual discs and cups.

Q. What if I experience skin trouble?

A. Stop using the product and check for issues related to detergent, fragrance, friction, or tightness. If symptoms persist or you experience severe pain or abnormal bleeding, consult a medical institution.
