MYTHYN’s story so far.

The Brand

Mathilde Gauvain - MYTHYN

Hi, I’m Mathilde.

Thanks for taking the time to learn about MYTHYN!

MYTHYN is my way of building a lifestyle that is more authentic and connected to nature.

Over the years I realised that the bath & body products I used invariably contained ingredients I did not understand. Did you know that many of the products we use every day lower our natural skin barrier and expose us to more and more toxins that end up staying in our system for years? Enters skin sensitivity, the new normal.

I started to build my knowledge of the ingredients, figuring out which ones were actually natural and recognising their beneficial properties. Over time I started making my own bath and cosmetic products… and then I was hooked. Blending knowledge of chemistry with herbal remedies, aromatherapy, and a holistic understanding of what feeds our bodies and mind helped me reconnect with nature and find a way that feels truly authentic and creative. After two years of experimenting, MYTHYN was launched in August 2016.

MYTHYN products are designed to nurture. I handcraft soaps, bath products, and cosmetics in small batches with high-quality natural ingredients such as nourishing oils & butters, minerals, botanicals and essential oils. My collections for MYTHYN are mindful, curated luxuries that bring a sense of wonder and delight.

I’d really love for you to get involved in our journey – say hi on Facebook, see our stories and posts on Instagram, or tag us in your tweets and we’ll reply to you!

Thank you

Sincerely, · Mathilde Gauvain
