Masterclass Monday: Understanding the Fundamentals of Clinical Trials in Skincare ft. Timeline and Dr. Brad Currier
In the third installment of the Skin Anarchy and Timeline Masterclass, Dr. Ekta Yadav sits down with Dr. Brad Currier, Manager of Clinical Trials at Timeline, for a behind-the-scenes look at what real evidence in longevity science and skincare actually requires.
With a foundation in muscle physiology, exercise science, and aging research, Dr. Currier brings a performance-driven lens to longevity — reframing skin not as a cosmetic surface, but as a mitochondria-dense longevity organ, biologically linked to muscle health, metabolic resilience, and cellular energy. The episode explores why mitochondrial function may be one of the most underappreciated drivers of how both skin and the body age.
At the center of the conversation is Timeline’s research on urolithin A, a postbiotic shown to support mitochondrial renewal. Rather than relying on marketing narratives, Timeline has built its platform on mechanism-first science, translating years of cellular research into human clinical trials — including biopsy-based studies that reveal measurable changes in collagen synthesis and skin structure.
Dr. Currier also pulls back the curtain on the truth about clinical claims in beauty — explaining why many “clinically tested” labels lack rigor, how underpowered or biased studies distort results, and what separates meaningful, published human data from perception-based marketing. From wrinkle depth to hydration to barrier function, he outlines how Timeline measures outcomes that reflect real biological change — not just surface-level improvement.
The episode ultimately reframes longevity as precision science, not hype — emphasizing the importance of human trials, mitochondrial health, and transparent evidence in an industry flooded with buzzwords.
Listen to the full episode of Skin Anarchy to hear Dr. Brad Currier unpack what clinical validation should look like — and why the future of longevity skincare depends on measurable biology, not marketing promises.
