Yttrium aluminium garnet

And I often think of that posterior polar case.

And you'll hear me say regularly in the cataract theatres, this is why they invented the YAG laser.

Just stop.

And I think that to me is the case which keeps me awake at night.

Nobel Prize in Physics, 2014.

And within a couple years, 1996, Nikia is selling the first commercial white LEDs, which is a blue LED with a yellow cerium-doped YAG phosphor painted on top.

Blue plus yellow makes something that looks white to the eye.

Looks white, doesn't render color.

Right.

The YAG laser operates at a longer 1064 nanometer wavelength.

This specific physical wavelength bypasses the superficial pigment entirely and safely targets the deep root of the follicle.

That is a life-saving public service announcement right there.

The type of laser is everything.

Yes, the doctors specify that an ND YAG laser operates at a wavelength that safely bypasses superficial melanin.

But if a clinic uses an alexandrite laser on brown or black skin, it will brutally target the epidermal melanin, causing severe thermal burns and permanent post-inflammatory hyperpigmentation.

You cannot blindly trust the machinery.

So I do have lasers.

I have a YAG laser, where you're, you're seeing a beam go right into the skin, and it can go into the skin, you know, different layers of the skin.

It can do damage.

It can be ablative.

I do, um, the, what I was talking about.

Yeah.

You know, a YAG laser to work on my tissue quality.

But you're lucky.
