How can there be more fluence inside the skin than is applied at the surface???

Here’s a strange thing…. When we fire a laser or an IPL at the skin surface we usually know the fluence that is applied. So, we figure that a 10 J/cm2 will penetrate into the skin and diminish with depth. Well, bizarrely, it doesn’t!! This is entirely due to scattering. So, what is scattering? The… Continue reading How can there be more fluence inside the skin than is applied at the surface???

The WRONG way to do laser tattoo removal!

It appears many people are using their tattoo laser wrongly! They are holding it off the skin, up to 10 to 20cm away. This is just wrong!! By doing this they will invariably apply a very small spot diameter at the skin surface which generates a huge fluence (energy density). Such fluences can easily damage… Continue reading The WRONG way to do laser tattoo removal!

Treating nasal thread veins with an IPL

IPL devices output a broad range of wavelengths which can be used to treat hair, blood vessels and pigmentation. We know that blood absorbs yellow light very strongly – typically in the region 500 to 600 nm (or thereabouts!) I trained some ladies (in ‘Mona Permanent Cosmetics’), recently, to use their IPL for telangiectasias (thread… Continue reading Treating nasal thread veins with an IPL

How strongly are different laser wavelengths absorbed in melanin and blood?

These days we use a wide variety of lasers and IPLs to treat various targets in the skin. Two major targets are hair and blood vessels. But how much of the laser/IPL light is actually absorbed by these targets? Using data from two very clever scientists (Steve Jacques and Scott Prahl) it is relatively easy… Continue reading How strongly are different laser wavelengths absorbed in melanin and blood?

The world’s FIRST ever commercial laser tattoo patient…

The other day I was training some very nice ladies and showed them a couple of photos of a tattoo I had treated with a Q-switched ruby laser. I realised, as I was talking to them, that this tattoo was the very first tattoo to be treated in our new, commercial clinic. Prior to this… Continue reading The world’s FIRST ever commercial laser tattoo patient…

How strongly do blood and melanin absorb light energy and how does this affect laser/IPL treatments?

WARNING – This post is a bit more scientific than my usual stuff. BUT, it is worth persevering because you will (hopefully) understand more about your laser/IPL treatments, if you do… When we fire light energy at the skin, to treat hair, blood vessel, pigmentation etc, we know that some of the energy is absorbed… Continue reading How strongly do blood and melanin absorb light energy and how does this affect laser/IPL treatments?

Laser Tattoo Removal – wavelengths and anisotropy

I’ve just made a couple of little animations looking at the differences between the laser wavelengths we use for tattoo removal and how anisotropy comes into play. You might be surprised at what actually happens in the skin. Anisotropy is rarely discussed in the laser tattoo world, yet it has significant effects on treatment outcomes.… Continue reading Laser Tattoo Removal – wavelengths and anisotropy
