Look at the back of your moisturizer. What's the first ingredient?
If it's water — and it almost certainly is — you're paying for something your tap provides for free. Most skincare products are between 60 and 90 percent water. Which means most of what's in your routine is diluted before it even reaches your skin.
Leila Haj Nassar, cosmetic chemist and founder of 100and1 Cosmetics, decided to remove it entirely — replacing water with pure Moroccan botanicals: argan oil, aloe vera, rose water, and actives that actually do something. Her co-founder Fatima Rosa, a licensed esthetician with over 15 years of hands-on client experience, brings what the lab alone can never know: what real skin needs, every day, in the treatment room.
In this episode, two founders who built from opposite ends of the same belief sit down with Lia to talk about water-free formulation, Moroccan ingredient heritage, and what the chemist and esthetician dynamic that makes 100and1 different actually looks like from the inside. A conversation about what conscious beauty really means when the formula is the whole point — and why paying for what you actually get should be the standard, not the exception.
