Agent Nateur Holi(C) - The C Duo, Youth Skin Refining Face Vitamines is a topical antioxidant powder to be mixed with your usual skincare to help refine and even the complexion in very visible ways.

A powder made of pure patented non-GMO Calcium, Ecocert approved, and non-GMO Vitamin C, to help fight free radicals and protect the skin against external agression, diminishing ageing signs (pigmentation, wrinkles, scars...), brightening and smoothing it back to its natural radiance.

Enough for 4 to 6 weeks care, it is also available in a 15ml version, enough for 3 to 4 months use. 


Strongly antioxidant Vitamin C boosts collagen production reducing thus the appearance of scars and wrinkles. It brightens and unifies the complexion, helping reduce rosacea, acne and redness as well.
Calcium improves skin elasticity, for a tightened, smoother, firmer complexion, repairing the skin's natural barrier and helping increase its hydration level.
This Face Vitamin blend helps reverse skin fatigue and sagging by 27%, as scientifically proven.


It is ideal paired with the Holi(Oil) Refining Youth Serum for a smooth, bright and glowing skin. See our "How to use" tab for all the details.



Jena Covello, founder of Agent Nateur, couldn't find beautiful, organic and efficient deodorant when she embarked on her quest to holistic cosmetics.

The skin absorbing from 64% to 100% (underarms) of the chemicals applied to it, she began to be as careful to what she was putting on her skin as to what she was eating. 

Looking to alleviate her chronic illnesses avoiding exposition to toxins, heavy metals and endocrine disruptors, she started studying and working on a clean deodorant formula with her chemist. Abiding to Europe strict safety regulations, using organic raw material only, to steer clear of toxin-charged ingredients, the products are even made with food-grade quality.

Agent Nateur was born in her West Hollywood kitchen, first the deodorant then also a precious skincare line. Upon growing as a brand, the formulas, purity and quality requirements as well as fun, lovely to use products, remain the same, handmade with love in Los Angeles.
Jena is determined to have fun with healthy AND gorgeous cosmetics, for our greatest pleasure, changing our outlook of what luxury cosmetics should be.
