As more people rethink their period products, the menstruation cup is shifting from a niche solution to a mainstream, sustainable choice. Reusable cups dramatically reduce waste, last for years, and offer a healthier alternative to single‑use pads and tampons. With growing awareness of the environmental impact of disposables, the question becomes clear: which material makes the best menstruation cup?
Across medical research, sustainability studies and user experience, one material consistently stands out: medical‑grade silicone. It’s safe, durable, body‑friendly and long‑lasting - making it the preferred option for anyone seeking sustainable menstrual products.
Below, we break down the science behind menstrual cup materials and explain why silicone remains the gold standard.
WHAT MENSTRUAL CUPS ARE MADE OF?
Most menstrual cups are made from one of three materials:
- medical‑grade silicone,
- latex,
- thermoplastic elastomer (TPE).
Each behaves differently inside the body and has a distinct environmental footprint. According to organisations like the FDA and Cleveland Clinic, silicone is the safest and most reliable option for internal use. Silicone cups - such as our Lunette silicone menstrual cup - are designed for long‑term comfort and sustainability.
SILICONE VS. TPE. What’s the Difference?
Many people compare silicone and TPE when choosing a menstrual cup. Both are flexible polymers, but their performance differs significantly.

Why this matters: TPE can be a good option for single‑use medical devices, but for a product designed to last years - like a menstrual cup - silicone offers superior stability, safety and comfort.
WHY SILICONE WORKS SO WELL?
Silicone begins as silica - a natural component of sand - and is transformed into a soft, flexible, highly durable material. These properties make it uniquely suited for menstrual cups.
Safe for Your Body
Medical‑grade silicone is:
- hypoallergenic,
- non‑toxic,
- non‑porous,
- biocompatible.
It doesn’t absorb fluids or support bacterial growth, helping maintain a balanced vaginal environment - a key factor for comfort and long‑term health.
Flexible & Durable
Silicone folds easily for insertion and springs open to create a secure seal. It maintains its structure even after years of use and repeated sterilisation - a level of reliability that TPE and latex struggle to match.
Easy to Clean
Because silicone tolerates high heat, you can sterilise your cup by boiling it. This makes hygiene simple and effective - ideal for anyone seeking sustainable feminine hygiene products that are low‑maintenance.
HEALTH BENEFITS OF SILICONE CUPS
1. Good for Sensitive Skin
Latex allergies are common, and some users find TPE irritating. Silicone is gentle and hypoallergenic, making it suitable for most people.
2. Free From Harmful Chemicals and No Microplastics
High‑quality silicone cups contain no:
- BPA,
- phthalates,
- latex,
- fragrances,
- dyes.
Unlike many disposable products, silicone does not break down into microplastics - a meaningful difference for both your body and the environment.
3. Supports Vaginal Health
Because silicone is non‑porous, it doesn’t trap bacteria. A study in The Lancet Public Health found that menstrual cups are as safe as pads and tampons, with no increased risk of infection.
WHY SILICONE IS BETTER FOR THE PLANET
1. Long‑Lasting
With proper care, a silicone menstrual cup can last up to 10 years. That’s thousands of disposable pads and tampons kept out of landfill - a simple switch with a significant environmental impact.
2. Lower Environmental Footprint
Life cycle assessments show that menstrual cups have the lowest environmental impact of all menstrual products - including organic cotton options. For anyone looking to reduce
WHY CHOOSE A SILICONE MENSTRUAL CUP?
In short, silicone cups offer:
- Safety: hypoallergenic, non‑toxic, body‑friendly,
- Comfort: soft, flexible, easy to use,
- Sustainability: long‑lasting and low‑waste,
- Durability: heat‑resistant and non‑porous.
If you’re looking for a healthier, more sustainable period option, a silicone menstrual cup like Lunette is one of the most reliable choices you can make.
WHAT'S NEXT?
The future of menstrual care is moving toward:
- bio‑based elastomers,
- improved recycling systems,
- circular‑economy take‑back programmes,
- medical‑grade material innovations,
- even longer‑lasting silicone formulations.
As sustainability becomes a priority for more people, menstrual cups will continue to evolve - but silicone remains the benchmark for safety and performance.
