For Christina Kuklinski, founder of KOOK, the ocean has never been a backdrop — it’s been a teacher.
A master scuba diver with more than 200 logged dives across destinations including the Galápagos, Palau, and Sipadan, Kuklinski understands firsthand what prolonged exposure to saltwater, sun, and wind does to skin and hair. After multi-dive days, she experienced the same issues many divers accept as inevitable: brittle hair, dry scalp, dehydrated skin, and sunscreens that either washed off or contained reef-harming ingredients.
What she couldn’t find on the market was something built specifically for people who spend hours underwater.
So she created it.
From Ocean Athlete to Founder
KOOK is an ocean-first cosmetics brand designed specifically for surfers, swimmers, and divers — those who spend sustained time in sun and saltwater. The product line is engineered for prolonged sun and saltwater exposure, delivering high-performance, reef-safe protection before, during, and after time in the ocean.

Why Divers Need Different Protection
Divers experience a unique combination of environmental stressors:
- Repeated immersion in saltwater
- Extended UV exposure during surface intervals
- Wind exposure on boats
- Mask friction along the face and hairline
- Rinse cycles that strip natural oils
Over time, this can lead to scalp dryness, hair breakage, skin barrier damage, and accelerated aging. KOOK was built to address those realities — not as repair-only skincare, but as preventative protection engineered for performance.
The brand uses non-nano zinc oxide, antioxidant-rich botanicals, fermented kelp, squalane, and vitamin E to support the skin barrier and defend against environmental stress. While nutrient-dense plant oils and waxes help coat the hair shaft, reduce saltwater absorption, and reinforce moisture retention at the scalp — minimizing dryness and breakage after repeated exposure.
All formulations are tested in real-world ocean conditions (not just controlled lab environments) ensuring performance during long boat days, multiple dive cycles, and extended time in sun and salt. Just ask some of our ambassadors: Rocio Bunker, Zac Araneta, and Jillian Morris-Brake.
“The ocean will always call bullshit on any marketing ploy,” Kuklinski says. “If a formula holds up through long dive days in salt, sun, and wind, that’s credibility you can’t manufacture.”
Reef-Safe, Responsibly Built
Beyond performance, KOOK’s environmental commitment is foundational.
The brand is:
- Certified B-Corp, Vegan and Cruelty-Free
- Reef-safe and free from oxybenzone and octinoxate
- Manufactured locally in Los Angeles
For divers who are deeply invested in marine conservation, ingredient transparency matters. The rise in reef-safe legislation globally reflects a broader awareness that what goes on our bodies ends up in the water. KOOK was designed to meet that moment.
Beyond formulation integrity, KOOK has embedded environmental restoration directly into its business model through its partnership with Seatrees. A portion of every purchase supports mangrove reforestation in Laguna San Ignacio, a UNESCO World Heritage site in Baja. Mangroves are critical marine ecosystems — they stabilize shorelines, improve water quality, provide nursery habitats for marine life, and sequester up to 4x more carbon than tropical rainforests. By contributing to mangrove restoration, KOOK aligns its growth with tangible ocean impact, ensuring that the communities and ecosystems divers rely on are supported long term.
A Growing Ocean Community
KOOK’s early adopters include divers, surf athletes, and ocean advocates who spend the most time in the water and demand the most from their products. This community-driven approach has helped validate the brand’s efficacy while building grassroots advocacy.
For Kuklinski, this isn’t about chasing beauty trends — it’s about serving a lifestyle she lives herself.
“Divers don’t need to be convinced that the ocean matters,” she often says. “They already know. The goal is to give them products that perform without asking them to compromise their values.”
As ocean tourism continues to grow globally and more people seek deeper connections with marine environments, the need for high-performance, ocean-safe personal care will only increase.
KOOK represents a new category within beauty — one built from saltwater sessions, conservation awareness, and a belief that performance and planetary care should never be at odds.
For divers who spend hours exploring reefs, wrecks, and blue water, protection shouldn’t stop at their gear.
Now, it doesn’t have to.
