Science-backed beauty. Uncompromising clean ingredients. Visible results.

Agent Nateur was founded by Jena Covello following her diagnosis with stage 4 endometriosis in 2003. Determined to take a more holistic approach to her health, Jena began examining everything she was exposed to- from the food she ate to the beauty, cleaning, and fragrance products she used every day, with a particular focus on reducing her exposure to potential endocrine disruptors.

That journey ultimately led her to create holi (stick), one of the earliest luxury natural deodorants of its kind: an award-winning, aluminum-free formula that proved clean beauty could be both elevated and effective.

What began with deodorant evolved into a lifelong study of formulation. Jena continued her education in the South of France, studying green beauty, clean fragrance and clean formulation while developing Agent Nateur’s approach to skincare, body care, hair care, supplements, and fragrance.

Today, Agent Nateur brings together clinically studied actives, bioavailable nutrients, exceptional natural ingredients, and luxurious textures to create high-performance formulas designed to deliver visible results without compromising ingredient integrity. Our award-winning holi (mane) marine collagen in partnership with Dr Will Cole became an international favorite for exactly that reason: people could see and feel the difference.

Every Agent Nateur formula is created with intention- to support the skin, hair, body, and overall well-being while delivering the efficacy you expect from luxury beauty.

No unnecessary compromises. Just thoughtful formulation, exceptional ingredients, and results you can see.

Beyond the packaging are high-performance formulas designed for visible transformation.

We partner with leading European labs to source and develop the highest quality active ingredients—rigorously tested for purity, safety, and optimal absorption. Every formula is created without compromise, using only what truly works.

"I have tried other collagen supplements before but they didn't give me the same results as holi(mane) does. My hair has less fallout, my nails are stronger and grow faster, and my skin experiences less breakouts." - Sarah

"I have been using Holi Mane on and off for over 4 years. I find when I use it regularly my skin is clear, my nails grow quicker and stronger and my hair grows to my waist easily." -Sarah
