Q&A
- Is it worth buying menstrual underwear?
Among women who swapped pads, tampons or cups for menstrual underwear, opinions are very positive. Most admit that Silver Care underwear performs well even on the first days of the period with heavy bleeding.
- Do you use pads or tampons at the same time with menstrual underwear?
Menstrual underwear are designed to provide protection themselves during menstruation. There is no need to wear an additional pad, but if you feel more comfortable with a pad, you can use it identically to normal underwear. You can also wear underwear for additional protection during your period when using a tampon or menstrual cup.
- Are menstrual underwear expensive?
Menstrual underwear are very economical and durable, so their purchase is financially sensible. One pair can serve us for 3-4 years without loss of absorbency. Following the manufacturer’s washing and drying instructions, this period can even reach 6 years (remember that underwear can last even longer, but their absorbency will gradually decrease – this process will not be noticeable for you). The cost of purchasing pads or tampons over a similar period is 3 to 6 times higher (depending on the brand of pads or tampons used) than purchasing 2-3 pairs of underwear. On top of that, there is incomparably greater comfort of using underwear due to the longer time between changes – 12 h for underwear vs 3-4 h for pads or tampons.
- Do menstrual underwear leak?
No, menstrual underwear do not leak, provided they are used and cared for properly. However, you should monitor your body and adjust the duration of wearing underwear according to your needs depending on the intensity of the period.
- Do menstrual underwear feel damp?
If menstrual underwear are washed properly, they do not lose absorbency and should keep up with absorbing moisture into the absorbent layer.
- Does menstrual underwear cause an unpleasant smell?
No, an unpleasant smell may occur sometimes if you have a vaginal infection.
- How often should I change menstrual underwear?
Replace a pad or tampon every 3-4 hours depending on period intensity. Menstrual underwear should be changed only twice a day.
- How many pairs of menstrual underwear should I buy?
We recommend buying 2 pairs of underwear. One pair we wear, the other is ready fresh for changing, but if you want to be sure there will always be a clean pair waiting, you can get more. The optimal amount is 3 pieces.

Tailored to your body – available in 4 sizes: S, M, L and XL
How to wash and care for the products?
- Wash before first use.
- After use, we recommend rinsing and/or soaking before washing.

- If using a washing machine, wash at a temperature not higher than 40º.
- For proper care, use neutral soaps. Do not use chlorine, bleach, fabric softeners, natural oils, or Marseille soap, as they may affect absorbency.
- Do not use a tumble dryer, as it may reduce absorbency.

1. How are Silver Care period underwear different from other menstrual underwear?
Silver Care underwear stand out from the competition thanks to 100% GOTS-certified organic cotton, free from plastic, polyester, or synthetics, which minimizes the risk of irritation and infections (e.g., vulvitis, TSS), as confirmed by independent lab tests. They offer the highest absorbency (77-166 g vs. 25-50 g for other brands) and guarantee absorbency for up to 100 washes (competition max 60), with no rustling noise when worn or when sitting down. They are biodegradable and hypoallergenic. Allegro rankings from 2022-2024 rated them the best on the market. Try the difference at masmi.com.pl!
2. Are Silver Care menstrual underwear safe for sensitive skin?
Yes, Silver Care menstrual underwear are 100% safe for sensitive skin! Made from certified organic cotton (GOTS-certified), they are hypoallergenic and free from toxins, pesticides, dioxins, chlorine, perfumes, or superabsorbents that can cause irritation or intimate infections such as vulvitis. Studies by independent labs confirm that organic cotton minimizes the risk of allergies and vaginal microbiome disturbances compared to synthetic materials. Experience the comfort and safety of Silver Care products – check them out at masmi.com.pl!
3. Why should you choose organic cotton over cheaper alternatives?
Organic cotton, like that used in Silver Care underwear, is healthier for intimate health because it is grown without chemical pesticides and fertilizers, eliminating the risk of harmful substances entering the body – the vaginal mucosa absorbs them within 4-8 seconds! On the other hand, synthetic materials, such as polymers or viscose, can increase the risk of irritation, yeast infections, or even long-term issues like endometriosis, as indicated by the American Endometriosis Association. Silver Care offers the natural quality and protection that cheaper products can't provide.
3. What does the GOTS certificate mean and why is it important?
The GOTS (Global Organic Textile Standard) certificate guarantees that Silver Care underwear are made from organic cotton produced in an environmentally and health-friendly way, without toxic chemicals or heavy metals. It confirms the highest safety standards – no pesticides, dioxins, or chlorine, minimizing the risk of infections and allergies. Silver Care is the only brand to apply such strict criteria, which sets it apart on the market. See the details at masmi.com.pl and see for yourself how important this is for your health!
4. Are Silver Care menstrual underwear worth it, even though they're more expensive than pads?
Yes, Silver Care underwear is an investment that lasts for years! One pair is guaranteed to maintain absorbency for up to 100 washes, which means up to 5 years (around 60 periods), while 10 packs of pads or tampons only last for 10–12 periods. With absorbency ranging from 77g to 166g (much more than the 25–50g offered by competitors) and no need for frequent changes, you save both time and money. It's a smart, long-term economic choice.
5. Can Silver Care underwear help with health issues, such as endometriosis?
Yes, Silver Care underwear can support intimate health, including for those with endometriosis. Organic cotton, free from dioxins and chemicals, reduces the risk of irritation and hormonal imbalances that can worsen endometriosis symptoms—WHO studies indicate a link between dioxins and this condition. The breathable structure and hypoallergenic properties of organic cotton also help protect against infections.
6. How long can I wear Silver Care menstrual underwear during my period?
Silver Care underwear is designed for up to 12 hours of use, thanks to absorbency levels from 77g (standard) to 166g (triple absorbency), outperforming competitors (25–50g). They're perfect for day or night, or while traveling—no need to change every 2–3 hours like with tampons or pads, ensuring exceptional comfort. Care for them as instructed (wash up to 40°C without bleach), and they’ll last you for years. Learn more at masmi.com.pl!
7. Are Silver Care underwear eco-friendly?
Yes, Silver Care underwear is 100% biodegradable thanks to organic cotton instead of plastic. They reduce menstrual waste, which adds up to 500 billion single-use products globally each year. The Silver Care factory uses solar panels and a closed water system, minimizing environmental impact. Make a conscious choice—see details at masmi.com.pl!
8. How should I wash Silver Care menstrual underwear to maintain their effectiveness?
