“Pain free” hair removal. Is it real?

We often hear, these days, about “pain free” hair removal, with various lasers, usually diodes. But, is it true? Well, let’s look at this more closely… The aim with laser, or IPL, treatment of hair is to induce enough heat in the stem cells that stimulate hair growth in the follicles. To do this, we… Continue reading “Pain free” hair removal. Is it real?

Laser/IPL Hair Removal – How many follicles do we kill each treatment?

All hair follicles grow according to a cycle – ‘anagen, catagen, telogen’. The follicle germative cells promote anagen hair growth at consistently regular intervals resulting in periods of active growth, followed by inactivity. The duration of these periods depends on the which part of the body is being considered. I created a computer model to… Continue reading Laser/IPL Hair Removal – How many follicles do we kill each treatment?

More on the ‘best’ intervals between laser/IPL hair removal sessions…

Choosing the ‘best’ time between laser/IPL hair removal sessions is not simple. It depends on the hair growth cycles of the hairs we are targeting, which is not the same across the body. That means that we need to consider the body area when deciding how long to leave between sessions. We can only target… Continue reading More on the ‘best’ intervals between laser/IPL hair removal sessions…

What is the ‘best’ interval between hair removal sessions (after treatment by lasers or IPLs)? Part 2.

I wrote a blog post back in September 2021 discussing my thoughts on the how to determine the optimum interval between laser/IPL hair sessions. It proved very popular amongst my readers. But, as soon as I posted it I began to doubt my own conclusions. Back then I suggested that we should wait for an… Continue reading What is the ‘best’ interval between hair removal sessions (after treatment by lasers or IPLs)? Part 2.

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…

The ‘best’ way to cool the skin during laser/IPL treatments

Many laser and IPL treatments require a significant temperature rise in the target cells, to effectively kill them. We use light energy to induce this temperature rise. But, calculations show that, in some cases, less than 1% of the light energy is actually doing the job we want. That means that more than 99% of… Continue reading The ‘best’ way to cool the skin during 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
