Yon-Ka Paris is proud to announce its new partnership with Opal Collection, becoming the exclusive professional-grade skincare line offered at all 12 of the brand’s luxury spa destinations.

Found in iconic coastal settings – from Maine, New York and New Hampshire to the Gulf and Atlantic coasts of Florida – Opal Spas will now feature Yon-Ka Paris in both face and body treatments, as well as in curated retail offerings.

Renowned for its expertise in phyto-aromatic therapies and its decades-long legacy of excellence in spa care, Yon-Ka Paris has set the gold standard in professional skincare since 1954.

Its formulations, rooted in essential oils and botanical science, have long been trusted by licensed aestheticians and medical spa professionals worldwide for their visible results and personalised approach to skin health.

“When selecting a skincare partner for Opal Collection, we were searching for a line that aligned with our values of wellness, integrity, and elevated guest experiences,” said a spokesperson from Opal Group. “Yon-Ka felt like a natural extension of what we strive to offer at Opal: thoughtful, intentional and deeply restorative spa experiences, guided by professional expertise.”

Trusted by professionals, loved by editors

From Vogue to Harper’s Bazaar, InStyle and Women’s Health, Yon-Ka Paris is frequently cited as a must-have by beauty editors. The brand’s success lies in more than just acclaim though. Used in over 6,000 spas across five continents – including 1,600 locations in the United States – Yon-Ka has become the go-to brand for skin professionals seeking results-driven, customisable treatments that deliver real, lasting benefits.

“We pride ourselves on being a brand that professionals trust,” said Antoine Lamarche, CEO of Yon-Ka Paris. “Each Yon-Ka facial begins with a personalised assessment by a trained aesthetician, followed by a fully customised protocol. From lymphatic drainage massage to advanced concentrates and age-corrective boosters, the experience is entirely tailored to the client’s skin condition and lifestyle.”

A shared legacy of family and excellence

The partnership also reflects a deep connection between the two brands. Yon-Ka was founded on the Mühlethaler family farm outside Paris in 1954 and remains independently owned and operated by the third generation, much like the Opal Collection itself.

“That shared value of family-run heritage and purpose-driven leadership was incredibly meaningful to us,” the Opal Group spokesperson continued. “At Opal, we’re not just creating luxury spa treatments – we’re crafting moments of connection, care and wellbeing. Yon-Ka helps us deliver on that promise.”
