So what's keeping your blood pressure elevated and your circulation slow?
Your metabolism breaking down.
Here's what's actually happening—and why it's not on your radar:
After 50, your body stops processing sugar the way it used to. You eat the same foods, but your cells don't respond to insulin like they did at 30.
That insulin stays elevated in your bloodstream. All day. Every day.
High insulin causes fluid retention (that's the puffiness and bags). And it keeps your blood pressure up, which makes those blood vessels stay visible through your paper-thin under-eye skin.
A 2021 clinical study published in Dermatology Online Journal found something surprising: Men with chronic dark circles had 83% higher insulin levels than men without them—even when they had the same body weight and diet.
The researchers concluded that persistent under-eye darkness might be an early warning sign of insulin resistance—the condition that leads to prediabetes and type 2 diabetes.
Now here's the part most guys don't realize:
You probably have insulin resistance.
Think about the last 5-10 years:
- Have your dark circles gotten actually darker and more noticeable?
- Have you gained weight around your middle, even though you're eating roughly the same as you used to?
- Do you feel more tired after meals than you did in your 40s?
If you answered yes to any of these, insulin resistance might be part of the problem.
Which is why the standard advice (sleep, water, and creams) isn't enough anymore.
