Kildare's Sonia Deasy, the founder of Pestle & Mortar, is a skincare entrepreneur with a unique story. Her journey into the beauty industry began with a personal struggle, as she faced skin issues and felt overwhelmed by the complexity of skincare routines. Drawing on her family's rich history of Indian natural healing, she embarked on a mission to simplify skincare without compromising on results.
Deasy's interest in business started early, with her father running a clothing and footwear store in Newbridge. Her hands-on experience in retail, combined with a UCD Philosophy degree, prepared her for the challenges of entrepreneurship. After managing the family store and setting up a wholesale fashion business, she married photographer Padraic Deasy and joined him in running a successful studio.
The Deasy's studio, located on Cutlery Road in Newbridge, was highly regarded, with Padraic being named European Photographer of the Year in 2011. However, the couple decided to close the studio in 2017 as Pestle & Mortar continued to grow. This decision marked a shift towards her skincare brand, which has since become an internationally recognized name.
Pestle & Mortar's success lies in its focus on science and simplicity. Deasy emphasizes that science always leads, and beauty follows. The brand starts with clinically proven ingredients and strips away any unnecessary components. This approach results in clean formulations, thoughtful textures, and products that deliver on their promises. Deasy's hands-on involvement in testing ensures that only the most effective products make it into the range.
As the beauty industry evolves, Deasy sees a shift towards results-driven minimalism. She believes that consumers are becoming more educated and demanding transparency, evidence, and integrity. Pestle & Mortar's commitment to these values positions it as a leader in the clean beauty movement.
Sustainability is another key aspect of Pestle & Mortar's mission. Deasy acknowledges the importance of long-term responsibility, not just quick wins. The brand focuses on reducing excess packaging, making smarter material choices, and creating products that people finish rather than discard. They are also constantly reviewing their supply chain to find better, more responsible solutions.
One of the hardest lessons Deasy has learned is letting go of perfection. She recognizes the importance of trusting her team, making decisions with incomplete information, and keeping the brand moving forward, especially during uncertain times. This mindset has been crucial in achieving work-life balance as a mother of five and a global skincare company founder.
Deasy's local roots in Kildare are deeply ingrained in the brand's identity. She believes that staying connected to her community keeps Pestle & Mortar authentic. This connection to real people, real skin, and real lives is what drives her and the brand's success. As Pestle & Mortar continues to grow, Deasy's advice to her younger self remains relevant: trust your instincts, take action, and embrace resilience.
