HYSSES values the natural sources of ingredients from mother earth as inspiration to drive product innovation. From botanical extracts to clays, we are dedicated to develop long-term relationships with all our farms, distilleries and artisans to deliver the best quality and genuine raw materials, by-passing all traders. All the ingredients are thoroughly reviewed by our Research & Development team before use. The research team not only focus on safety and efficacy of the products but also ensuring 100% compliance to the registration and registration requirement for international market needs except for Animal Testing policy. We are against Animal Testing. Ecocert or Cosmo Certification are the some of the recognition requirements for our raw material supply chain.

The Singapore manufacturing facilities and processes are governed by the GMP standards issued by Singapore Health Science Authority.

At HYSSES, every essential oil undergoes GC/MS (Gas Chromatography/Mass Spectrometry) testing to verify purity, potency, and authenticity. This certification ensures our oils are 100% uncompro—free from synthetic additives or dilution. It's our promise of uncompromising quality, so you experience nature’s true essence in every drop.

All our formulations are approved under the Cruelty Free International Leaping Bunny and PETA Programme. We do not test our products on animals except on ourselves.

We took pride in our formulations and volunteer in testing out our formulations on ourselves in addition to the safety and efficacy checks. All manufacturing batches are dispatch to third party laboratory for ensure 100% microbial free and product safety before putting them on the shelves.

Sustainability has always been central to HYSSES’ mission. From sourcing recycled PET bottles to setting annual goals of reducing our carbon footprint by 10%, we are committed to building a greener value chain. Our first refill centre, launched at the Heritage outlet in Haji Lane, allows customers to reuse their packaging through eco-friendly dispensary machines — promoting a circular economy.

Since 2015, we’ve replaced all plastic bags with recyclable alternatives, later refining them into foldable designs to encourage repeated use. In 2020, we expanded this initiative by urging customers to bring their own bags. As part of Singapore’s Green Plan 2030, HYSSES proudly supports the NEA’s “Say Yes to Waste Less” campaign, contributing to the national goal of reducing waste-to-landfill by 20% per person by 2026.

At HYSSES, we champion inclusive employment by offering equal opportunities to individuals of all backgrounds, including the physically disabled, ex-offenders, and mature workers. Through fair hiring, training, and partnerships with privately funded non-profits, we empower lives and give back to communities—creating lasting social impact beyond our workplace.
