The Peptide Secrets to a Youthful Face : 1536

Carolina Reis de Oliveira, PhD
SpotifyApple PodcastsShow Notes

Dave Asprey talks with Carolina Reis de Oliveira about the science of skin aging, from the breakdown of the skin's barrier in menopause to the role of senescent 'zombie' cells. Carolina explains how her team developed the peptide OS-01, which was associated with a 2.5-year reduction in measured biological skin age. They also discuss why over-moisturizing and slugging can disrupt the barrier, the impact of GLP-1 weight loss on skin, and why peptide formulation matters more than just GHK-Cu content.

•
Senescent Cells as Drivers of Skin Aging00:18:20
Accumulated senescent 'zombie' cells in skin release inflammatory signals that damage nearby cells and degrade collagen, accelerating the physical signs of aging.

OS-01 Peptide Reduces Biological Skin Age
In OneSkin's research, the OS-01 senomorphic peptide was associated with a 2.5-year reduction in measured biological skin age, along with improvements in fine lines, wrinkles, and firmness.

Highlights

•
Skin Barrier Breakdown in Menopause00:04:31
Declining estrogen during perimenopause and menopause accelerates the loss of collagen, ceramides, cholesterol, hyaluronic acid, and elastin, disrupting the skin's 'brick and mortar' barrier and leading to dry, thin, and crepey skin.

•
GLP-1 Weight Loss and Loose Skin
Rapid weight loss from GLP-1 agonists can cause loose, sagging skin due to the loss of underlying fat and concurrent breakdown of collagen and elastin.

Editorial

•
Over-Moisturizing and Slugging Can Disrupt the Skin Barrier
Excessive use of heavy occlusives like Vaseline or 'slugging' can weaken the skin's natural barrier by reducing the skin's own lipid production, leading to increased water loss over time.
