How Peptides Combat Collagen Loss

As if we didn’t have enough to deal with managing low energy, mood swings, and brain fog, within the first five years after menopause, we can expect to lose 30% of our skin’s collagen — and collagen production continues to drop another 2% every year for the next two decades!

Even if you aren’t concerned about the aesthetic impact of collagen loss (namely lines, wrinkles, and sagging skin), there’s a health component involved, which I explain in more detail below.

But what triggers these changes? Just like other symptoms common in perimenopause and menopause, it’s due to shifts in estrogen and progesterone.

The Role of Estrogen and Progesterone on Skin

  • Skin Barrier: Estrogen stimulates the production of several key proteins in the skin, keeping your skin barrier healthy and strong. However, as estrogen levels decrease, your skin can become thinner over time [*], which puts you at greater risk for moisture loss, infections, and UV damage.
  • Oil Production: Declining levels of progesterone can lead to skin that’s drier and more sensitive since this hormone is involved in the skin’s oil production.
  • Free Radicals: As estrogen levels drop, the body’s natural defense [*] against free radicals becomes less effective, leading to accelerated skin aging.
  • Hyaluronic Acid: Estrogen also stimulates the production of hyaluronic acid. Without a strong skin barrier and the estrogen-stimulated production of hyaluronic acid, the skin will feel more dehydrated [*].
  • Sun Sensitivity: When estrogen levels decrease, so does melanin, the pigment that helps protect skin from UV rays. This means, you might notice that your skin becomes lighter and that you’re more sensitive to sun damage [*].

How I Keep My Skin Healthy After 40

In addition to eating foods rich in antioxidants, using broad spectrum sunscreen, and getting quality sleep — which can all affect the health of your skin — I recently found a skincare line developed by a team of female scientists.

The company is called OneSkin. And their products, called “topical supplements,” are powered by their proprietary OS-01 peptide which is scientifically proven to counteract some of the factors caused by estrogen decline during menopause.

In lab studies, they found that OS-01 increased collagen and hyaluronic acid production in skin (1), improving firmness, elasticity, and hydration and strengthening the skin barrier (2). Not only that, their peptide is proven to reduce cellular senescence (3), one of the hallmarks of skin aging, so your skin stays younger and healthier as you age

I’ve shared with my Bettys that I’m completely up-leveling my skin this year. I’d love for you to consider how you can do the same. My absolute go-to product from the OneSkin line is OS-01 SHIELD Protect + Repair SPF 30+. This mineral-based sunscreen comes in both tinted and clear.

1) Shown in lab studies on human skin samples by measuring collagen production biomarker, COL1A1, and hyaluronic acid production biomarker, HAS2. Treatment with the OS-01 peptide displayed a significant increase compared to no treatment. (Zonari, A., et al. npj Aging, 2023)

2) Shown in a clinical study performed by a third party research organization. Skin barrier and hydration measured by a vapometer. Elasticity and firmness analyzed via double-blind expert clinical grader evaluation. Significant improvements were observed on skin treated with OS-01 FACE for 12 weeks versus baseline. (Zonari, A., et al. Journal of Cosmetic Dermatology, 2024)

3) Shown in lab studies on human skin samples and/or cells by measuring the number of senescent cells via SA-Bgal staining, senescence biomarkers (CDKN2A/P16, CDKN1A, H2A.J), and SASP biomarkers (CXCL8 and IL-6).  Treatment with the OS-01 peptide displayed a significant decrease in all mentioned markers compared to no treatment.
