The anti-acne and anti-aging skincare brand that promises to formulate its products with no pore-clogging ingredients has appointed beauty industry veteran Diana Dennett as President.
Before joining Clearstem, Dennett held leadership roles with leading beauty brands including Oliveda (Olive Tree People), Dermalogica (Unilever Prestige), and Juice Beauty, driving growth across retail, professional, and direct-to-consumer channels. A dual-licensed esthetician and cosmetologist, Dennett began her career in the treatment room as a salon owner, bringing a deep understanding of the professional beauty community and a unique perspective on brand growth and consumer needs.
In a new role, Diana Dennett will lead the company’s commercial strategy and operational growth across direct-to-consumer, retail, and professional channels as the brand continues to expand its presence in the skincare industry.
"Diana’s extensive experience across beauty, retail, and operations makes her an incredible addition to Clearstem’s leadership team," commented Danielle Gronich, CEO and Co-Founder of Clearstem. "Her ability to connect brand vision with strategic execution will play a key role in strengthening our brand and supporting upcoming phases of growth."
Founded by Danielle Gronich, also known as "The Acne Guru" and Integrative Healthcare Practitioner Kayleigh Christina, Clearstem targets breakouts and aging at the same time with no pore-clogging ingredients.
"The beauty industry doesn’t need more products; it needs education-backed innovation that actually solves complex skin issues," said Diana Dennett. "Clearstem solved a massive industry void by addressing acne and aging together, eliminating the frustrating choice between harsh acne treatments or pore-clogging anti-aging creams. Moving forward, we aren’t just scaling a brand; we are redefining the benchmark for what skincare can achieve. I am thrilled to join this powerhouse team as we push the boundaries of skincare and shape the future of the industry."
