In 1872, chemist John Watson patented a technique for making a solution of benzene and iodine to kill bacteria.
He called it a “chemical steriliser”.
That same year, in the United States, the US Patent Office gave a patent for a method of “bacterial killing” using an iodine solution.
This chemical steriliser worked by making a chemical reaction in the body and then the reaction would produce an electrical current.
This was the first of many chemical sterilisers that were patented in the US and the world.
For decades, they were used as a cheap way of sterilising surfaces.
In the early 20th century, scientists realised that using the same technique for skin was possible and the “skin” was just a collection of chemicals.
They called this “the first laser”.
In the 1960s, a team of British researchers developed the first successful laser, and by 1970, there were over 1,200 lasers in use worldwide.
The first successful skin laser in the UK, invented by chemist William Hinton in the 1940s, was used in the 1960’s.
In 1962, a French researcher invented a second laser that used the same principle of using the reaction between the iodine and benzene in the original one to make a current.
Today, there are over 2,200 laser systems in use around the world and their range of applications has been vast.
“The biggest challenge in the skin laser is to get the concentration of the iodine in the solution enough so that the reaction occurs.
We need the concentration to be high enough so the reaction will occur and the current will be strong enough to produce enough heat to generate enough heat that the bacteria die,” says Dr Michael Jervis, the director of the Skin Care Institute at the University of Sydney.
A laser skin treatment can be as simple as applying a gel containing an emulsion of water and a solution containing a small amount of titanium dioxide.
Then, a laser beam is focused onto the skin.
This laser burns through the collagen and elastin in the epidermis and can cut through the skin and the outer layer of skin, which contains fatty tissue.
At the other end of the spectrum, lasers can be used to treat deep eczema or psoriasis.
When lasers are applied to the skin, the water in the emulsion dissolves the skin’s oil, causing a reaction.
The skin then releases the oil as a liquid, which can be injected into a catheter.
The water from the laser reacts with the skin to form a solution that is then injected into the catheter to be flushed away.
One of the first tests was to use a laser to treat the skin of a man who had eczematous keratitis.
He was given a topical corticosteroid cream and asked to apply it to his arm and then on his thigh.
Within 48 hours, he noticed a dramatic improvement in his eczymatous skin.
The next test was to take a sample of his skin from his forearm and compare it to that of someone who had not been treated with the laser.
The results showed that the person who had been treated was more sensitive to the laser treatment.
These lasers can have a wide range of effects.
One of the biggest advantages of lasers is that they are easily used on sensitive skin.
However, it is also possible to damage skin or damage the underlying cells.
Dr Jervises says it is important to use caution with laser treatments.
“It’s a very delicate and delicate process.
The next big thing is that lasers can also be used for other applications, like skin cancer research, where it is possible to make the reaction in a lab and then test the results. “
We recommend that you have a skin test to make sure you’re safe to use them.”
