Beauty Osmosis® is the principle that characterizes
the entire production process of each of our products, from design to realization.
Based on scientific foundations, our method involves the use of products and raw materials that our skin recognizes as familiar.

In this way, your skin will be able to:

I numeri primi principi attivi

Absorb all the beneficial active ingredients of our organic, natural, and vegan ingredients

Home

Breathe better, forgetting pimples and other imperfections

I numeri primi principi attivi

Regenerate, resulting in a more luminous, beautiful, and youthful appearance

Prime numbers are special digits divisible only by one and themselves.
They represent a fascinating uniqueness, just like your beauty and your skin

My name is Marialetizia Benini Galeffi and based on this concept, I have developed I Numeri Primi, organic and natural skincare line.

Thanks to my pharmaceutical background and the special observatory from which my family has been studying care and beauty habits and skills for over 250 years, the Antica Farmacia Galeffi, opened in 1763 in Montevarchi, in the heart of Tuscany, what I Numeri Primi can guarantee is beauty, sustainability, and efficient products.
The Beauty Osmosis® principle characterizes all I Numeri Primi products and is based on a fundamental concept: providing our skin with natural products that can be recognized as familiar to being absorbed more effectively and derive greater benefits. I Numeri Primi product formulas are created from pure natural botanical ingredients, rich in high-performing and delicate active principles, with 100% Italian production.
Our products do not contain parabens, colorants, silicones, mineral oils, or allergens, are not tested on animals, and are organic. Because we want to offer your skin a gentle, effective, and functional treatment without having even the slightest impact on the environment.
