Ocean-Inspired Wellness with OSEA

From sea to skin,
we’re making waves to heal our planet.

In celebration of World Oceans Day and throughout the year, Cambridge Beaches Resort & Spa and Benchmark Resorts & Hotels are partnering with OSEA to bring guests restorative wellness experiences that support the preservation of our oceans.

For every Ocean Renewal treatment reserved at Ocean Spa, we will contribute $25 to 4ocean — helping support global ocean, river, and coastline cleanup efforts through the removal of 25 pounds of plastic and debris with each treatment.

Ocean Renewal Treatments

Through exclusive OSEA facial and body treatments, we’re transforming ocean-inspired wellness experiences into meaningful moments that give back to the waters that inspire them.

OSEA is a family-founded skincare brand that is vegan, cruelty-free, clinically tested, and committed to ocean and climate responsibility.

This limited-edition treatment blends potent seaweed extracts with active botanicals to hydrate, smooth, and revitalize skin. The experience begins with OSEA’s signature calming, craniosacral therapy–inspired touch and a custom cleanse, followed by an infusion of sea minerals and hyaluronic acid for a refreshed, healthy-looking glow. A therapeutic neck, shoulder, and hand massage melts away tension.

Ocean Renewal
Body Ritual

This limited-edition ritual blends mineral-rich sea salts with potent seaweed and active botanicals to smooth, visibly firm, and replenish the skin. The experience begins with a full-body exfoliation using pink Himalayan and red Hawaiian sea salts to refine and energize, followed by a firming seaweed body mask infused with ceramides, niacinamide, aloe vera, and amino acids to deeply condition and restore. A grounding, full-body application of seaweed-infused oils, including passion fruit and açai, melts away tension.

    4ocean Impact

    Since launching its partnership with 4ocean in 2025, Cambridge Beaches Resort & Spa and Benchmark Resorts & Hotels have contributed $10 per room night when guests book the dedicated 4ocean experience — equating to an additional 10 pounds of plastic and trash removed per night.

    Guests looking to support ocean cleanup efforts without booking a specific spa or room package can also make an optional contribution through Benchmark’s reservation platforms.

    The Brand, OSEA

    Committed to Our Oceans Since 1996

    OSEA is a seaweed-based skincare brand inspired by the healing power of the ocean. Their name stands for Ocean, Sun, Earth, and Atmosphere — reflecting a philosophy rooted in protecting the natural elements they draw from.

    Since 2022, OSEA has partnered with SeaTrees to support coastal restoration projects. Through Ocean Renewal, they continue that mission by combining ocean-inspired skincare with efforts to help protect and restore our waters.
