Green Lasers and Hair Removal Theory

CO2 Lasers and Scar Removal Theory

After my previous experiment, I have now got facial scarring over my face and am still growing a beard. I heard about CO2 lasers being used to remove the effect of scarring. Should I go for a 50W or an 80W tube to do the job?

Lol, Oliver, this is quite a black humor IMO.

Lol, we have to find some humour in this don't we. Plus, I was hoping for it to be a last attempt for the idea to finally sink in. He shouldn't do it himself and this is what could possibly happen. He probably will still go ahead with it despite the fact that more people have said that it is stupid.

Humor is important, what would be life without it?

Well, it seems like telling a kid not to touch hot oven, untill the kid does not gain experience with burnt hand, no advice is listened.

To OP: You have been warned enough here and only you are responsible for your health.

Unfortunately if you hurt yourself you might do bad reputation to our laser hobby as this will be another case of stupid missuse of lasers counting to calls for stronger regulation and restrictions in reality complicating it only to legitimate and responsible users. There is enough idiots (pointing lasers at aircrafts, cars, shining to others eyes etc.) out there, do not add to them by doing that.

Howgh.

I think there is nothing more to be discussed here.

Yep, we need humour.

That is exactly what it is like. Well, I don't want to be the one to say I told you so.

Definitely go for a model over 100 watts.

If it doesn't work well for removing hair, it will be excellent for removing cataracts later in life. The coolest thing: When used to remove cataracts sutaining the beam amout a minute longer will also make it very effective in performing a lobotomy!

There is a slight risk to it though: When completing the lobotomy you may no longer be fully aware of what you are doing, and the laser could cause some damge to things like wallpaper and drapes ones it burns its way out of the back of your head. Woulds will probably be cauterized so you will not bleed to death, although chances are at some point in the future you wished you did.

:crackup: Now that's dark humour!

Lol. I've a nice comparation to evaluate these levels of black humor, but it is too racist to mention it here.

On a more serious note -a disadvantage of destroying hair follicles is that in the hair follicle, stemcells reside in a discrete microenvironment called the bulge, located at the base of the part of the follicle that is established during morphogenesis but does not degenerate during the hair cycle. The bulge contains multipotent stemcells that can be recruited during wound healing to help the repair of the epidermis.
Another disadvantage of permanent (by laser or electrolysis) hair removal is a decrease in regeneration ability of human skin, since hair follicles contain stem cells which help with healing.

Very good points Encap.
I didn't think of that. Another reason for you to shave like the rest of us then Objective.

You're right--sorry about that--thanks for the heads-up--have changed the link to a 22 March 2017 webcache page -- +rep when possible.

Here again is the webcache of the page -- you don't need an account to view it:
Hair Follicle Stem Cells--New Insights & Clinical Relevance

No problem Encap. Thanks, interesting article. +rep for you as well when I can. :beer:

Guys, please stop posting interesting stuff, I cannot manage to read everything with such a limited time. Joke. I appreciate that a lot. LPF is the most usefull "social network" for education not only about lasers for me.
Thanks again, Encap. I've repped you today already, so spread limit applies.

So shortly said it is unwise do destroy useful tissues that otherwise pose no harm to the human body?

It seems pretty logical to me - you don't go yanking out your nails with a pair of pliers so you don't have to clip them for a while either, right?

Seriously though, most parts of the body including hair in various places just serve a function. Things like eyebrows are not decorative features, they serve to keep things like sweat dripping in your eyeballs. Hair in your nose and ears keeps harmfull stuff from getting in there.

You can trim these hairs for cosmetic reasons and they will grow back if you somehow discover a disadvantage to lacking them, but if you irreversibly remove them you could have a problem at some point. These problems could be quite unexpected and dangerous, like accidentily snorting up a mosquito that stings you on the way in
