Sapphire FUE

Microchannels

The blade does create microchannels and is both harder and sharper than steel.

However, the trauma is arguably greater, as sapphire blades are nearly twice the thickness of steel cut blades.

If the sapphire blade was the same size as a regular blade, it would make the same wound, cutting the same tissue and the same blood vessels.

Tumescence

Prior to FUE clinicians inject a saline solution into the scalp. This solution is known as tumescence, and there's nothing particularly special or harmful about it.

Injecting tumescence is a precaution taken to improve the density of the cuts. Clinicians don't inject an unreasonable amount to begin with.

Clinicians will not simply avoid using normal precautions because we chose a tool with a different blade.

Depth Management

Sapphire FUE doesn't improve depth management one way or the other. A human controls the tool.

It will go as deep or as shallow as the clinician makes it go, regardless of whether they use a steel blade, a sapphire blade, or a ball-point pen. Obviously no surgeon would use a pen, but the point remains the same.

Depth management is about skill, not blades.

Sharpness

It's true that sapphire is very hard and the blades are very sharp.

Follicle Preservation

The site making tool never interacts with the graft unless the graft is loaded into a DHI tool. Even then, unless the handler damages the graft, the damage factor is equivalent.

Antibacterial and Antimicrobial Properties

There is no supporting evidence and no studies that support this claim. It also doesn't matter.
