Did you know your skin has its own internal clock — and that ignoring it could be accelerating aging? In this episode of the Science of Skin podcast, board-certified dermatologist Dr. Patti Farris sits down with renowned cosmetic dermatologist and Harvard graduate Dr. Ava Shamban — founder of AvaMD Dermatology and the skincare line Althea — to break down the fascinating science of circadian rhythms and skin health.

They cover:

• What circadian rhythms actually are and why every skin cell has its own biological clock
• How clock genes control 50% of your genome — and drive collagen production, DNA repair, and barrier function
• Why screen time, blue light, and night-shift schedules are silently destroying your skin
• The emerging field of chrono cosmetics — syncing your skincare routine to your skin's natural 24-hour cycle
• Dr. Ava's science-backed skincare line Althea and its groundbreaking day/night formulations
• Her new multimodal at-home device featuring LED therapy, radio frequency, and microcurrent — pending FDA clearance

Whether you're a skincare enthusiast or a medical professional, this episode will completely change how you think about anti-aging, skin longevity, and your nighttime skincare routine.
