Why Your Skin Doesn’t Age on a Straight Line.
I recently read about this study and found it interesting so I thought I would share. The study states that your body doesn’t age gradually, but in bursts - with two major turning points, right around age 44 and again at age 60.
In 2024, this Stanford study tracked over 100 people for several years, measuring thousands of molecules in their blood, gut and skin. What they found: most of these markers didn’t drift slowly over time. They shifted dramatically, clustered almost entirely around two ages - 44 and 60 - with comparatively little change in between.
What’s actually shifting
In your 40’s, the biggest changes were tied to lipid metabolism, cardiovascular markers, and alcohol processing- all systemic changes with visible skin consequences. This is right around when we typically see:
-Collagen production slowing and collagen breakdown (via enzymes called MMPs) picking up
-Early hormonal shifts affecting oil production, hydration, and barrier strength
-Slower skin cell turnover
In your 60’s, the dominant shifts were in immune regulation and carbohydrate metabolism. This tends to show up as:
-Slower wound healing and longer recovery after treatments
-More inflammation-driven pigmentations and redness
-Compounding collagen/elastin loss-basically the skin has less structural “reserve” to bounce back from new stress.
The takeaway for skincare
If biological change is concentrated in these windows rather than spread evenly across decades, it makes sense to build up your skin’s resilience before you hit these benchmarks not after you start noticing the changes that occur with them.
Heading into your 40s: this is prime time to introduce or strengthen a retinoid routine, since collagen support and cell turnover are what’s under the most pressure during this transition. It’s also a good moment to shore up your barrier - ceramide and lipid-based products help offset the hormonal shifts affecting your skin. As far as professional treatments go, I love micro-needling for helping with these two things!
Heading into your 60s: barrier repair become even more important, since immune and inflammation regulation is what’s shifting. Look for barrier focused, anti-inflammatory formulations that support your skin’s own healing capacity rather than just address surface texture. Glo2 facials are great for these goals as the oxygenation action regenerates the tissue and as time goes on teaches the skin to act in a more healthful manner.
Not sure where you are in your skin’s timeline?
A consultation is the best way to figure out what your skin needs right now rather than guessing on your own.
