Here's some simple ipl 101. I wanted my hair gone, so a couple years back instead of paying 10k for the total body hair removal for my mostly baby blonde hair, I bought a professional unit from china that has 3 different tools from ipl, laser, and 2 pole rf.. I bought it from some of my overseas connections, so I got it around 4k instead, may sound expensive, but you get what you pay for(in other words, keep reading).. my mistake was thinking a manual would come with it:( it took over a year to find the correct ipl manuals and textbooks on the net..
This next part explains how an ipl works.. sadly after this, it's your choice if you still only want to pay up to 450 for an ipl machine. Basically that could in theory help dark haired people with very light skin. But with the head that is 1 inch square, good luck doing your body:(
Ok, so you got your ipl, now do you have filters in it that filter out the light below 640nm. What is the power output of the unit. For my blonde hair it takes 18 joules of energy per shot.. then there is the duration, with this being said, it's not just a flash, but how long is that flash? Again for a blonde I set my unit for 15ms, then off for 5ms skin cooling, then another 12ms heat, so basically in that shot, I get 27ms of heat. This is designed with the head of my unit since it uses a cooling head that's always 35f to keep the skin cool and prevent burns, the time is so the light penetrates far into the hair folic to heat the hair up to cauterize the blood flow to the hair. Lost ya yet:) Ok within that same shot, now it sends a pulse of rf, just like electrolosis that causes the hair folicles in between the ipl head to cause a galvanic action that produces sodium hydroxide in the hair folicle. This helps ensure the hair doesn't heal and come back.. the setting for this action is 450ms at an rf rating of 20w, I should go higher and longer on this setting, but I'm not too fond of electric shocks! now if all this worked, the hairs in this section should fall out in a couple days by themselves.. and if all your settings were at max if you could stand the pain, you may kill up to 90% of the hair in the active growth cycle at that time in that location..
Last piece, there are different growth cycles, usually 3 main cycles that go from 4 to 8 weeks. You will notice no hair for a couple weeks, then a cluster of hair start growing, so time to start over again..
There is soo much I didn't talk about on this, such as gels, numbing creams, other setting, the sun, post treatment.. I just wanted to show you how a pro unit works so you can see that an even $450 unit lacking half the stuff to accomplish the job in just that one flash. It may work for dark hair, but it's a long shot, plus it can cause damage and scars if your skin is not right due to tan, skin color, or even stuff you may put on your skin..
And yes, with my ipl, I've removed almost all my body hair, hair down there:) and some facial hair.. now the facial hair is a different animal, most of those cheaper units say not to use on the face for that factor that they are not truly controlled and the head is not thermally cooled and some people could acquire permanent scars:(
I still use the unit every 5 weeks on my face at lower settings to remove hair do I don't have to spend the next few years at the electrolosis.. now those hurt and it gets expensive, so I'm trying to shorten that time.. Basically if you notice scaring or pain while doing your skin elsewhere, do not touch your face! Just removing 10% of the hair at lower settings is better than a perm scar!
Ok, hope I have helped cover some questions? Pm me or email if you have more questions:) i may see if i can upload some documents to the site on ipl tech and use.. my suggestion is to make a group and go in for a pro unit, then take turns on each other. It's soo much easier when you have a buddy helping todo it.. a pro unit lasts 100k to 500k flashes before you spend over another grand to buy a new head, but that is 20 to 30 people or more over its life.. oh, and use plenty of lube;)
Last, again the smaller unit may work for you, but best results if you have dark, thin hair, with light skin, and can tolerate the pain so it can be on high to no scars! Good luck!
