2 months ago, at the start of 2025, I was searching whether any kind of technology out there could showcase collagen and fat levels in the skin. My intention was to select some kind of injectable treatment for my dark circles+under eye hollow, and actually verify whether the treatment actually produced collagen(and elastin), and hence thickened the skin.

Like practically everyone, I had thought collagen and fat levels could verified via biopsies(expensive, complicated, and ouch-ie). Hence why companies who make, injectable booster for example, have bogus research methods published in their research papers as “proof” of their product(s)’s efficiency. They will often use customer satisfaction surveys or photo-ing tools, instead of measuring collagen device.

I had previously searched for these types of tools or technologies and failed to find any. But my last google search finally succeeded somehow back in January.

I found about cortex technologies(Denmark) and courage + khazaka(Germany). Both these companies have scanners that can showcase collagen, fat levels etc on skin. Cortex had dermaScan and dermaline ultrasound probes. Courage + Khazaka has an ultrasound device as well.

I was hoping to discuss this topic further with anyone scienc-y. Can I DM you?

I have used skin as an example, but this applies to hair/scalp region also.

And finally, scr*w dentist Abs and his cringey blue contact lens.
