"Intense Pulsed Light (IPL) is a method of permanently removing hair from the body" - true or false? I've seen various claims stating that IPL may produce a permanent result, but very few clinics in practise will claim this. It's a contentious claim - see [1]. Comments, anyone? - PeteC 16:55, 3 May 2005 (UTC)

Stem cells in hair follicles? Is there any scientific data to support such a notion? ---Peter, 6 June 2007
Certainly – a number of multipotent stem cell repositories are found in the dermis. The main purpose of these cells are to renew damaged or dead tissue structures. Please notice, these are not identical to the pluripotent stem cells that people are discussing so intensely these years. The dermal multipotent stem cells creates dermal cells only – not new organs or anything else. If you search PubMed or Google Scholar using the search term "stem cells" AND "hair follicles" a number of high quality literature is found – many of the papers are printed in peer reviewed magazines. One paper that sums things up nicely is: J Investig Dermatol Symp Proc. 2003 Jun;8(1):28-38. Hair follicle stem cells. Lavker RM, et al. A more ”popular” reference is found at this BBC news page --- Bo 212.242.116.214 21:07, 27 October 2007 (UTC)[reply]
ipl is really a good way for epilation. —Preceding unsigned comment added by 210.22.180.166 (talk) 08:53, 14 January 2009 (UTC)[reply]
This page is terrible given the commonness of this type of treatment and technology. I've researched and written many papers on hair removal over the years and will spend some time on it during coming weeks. XavierT3000 (talk) 09:38, 20 June 2012 (UTC)[reply]
The previous version of the Definition section of this page claimed that laser hair removal carries a "radiation risk". I guess the author thinks lasers cause cancer? If so, then lightbulbs do too. Whether monochromatic or not, it's all just visible light. I've changed it and added an external link to a page with a list of peer-reviewed clinical research. Please try to use these or similar sources when adding medical information to this page. Telefox (talk) 22:27, 1 August 2012 (UTC)[reply]
Good job user Pol098, that page looks a lot better now. It'd be nice if a professional could add some expert advice as well. This is a low-priority article, but it's the kind of thing people need an unbiased source of information about. Telefox (talk) 10:37, 15 October 2012 (UTC)[reply]
Regulations Regulations cover IPL under the topic of Non-ionising radiation. The EU issues directives which are then transposed into national law by the member countries. For every application several directives might be applicable. For example IPL applications will fall at least under the directive regarding non-ionising radiation and the medical device directive. Directives are general legal requirements. For application to devices there are standards, such as EN 60601-2-57 (http://shop.bsigroup.com/ProductDetail/?pid=000000000030165798) Particular requirements for the basic safety and essential performance of non-laser light source equipment intended for therapeutic, diagnostic, monitoring and cosmetic/aesthetic use EN 62471 Photobiological safety of lamps and lamp systems
Directive: minimum health and safety requirements regarding the exposure of workers to risks arising from physical agents (artificial optical radiation) (http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2006:114:0038:0059:EN:PDF) Germany: Gesetz zum Schutz vor nichtionisierender Strahlung bei der Anwendung am Menschen (NiSG) (http://www.gesetze-im-internet.de/bundesrecht/nisg/gesamt.pdf) The German wikipedia article to IPL is found under Epilation: http://de.wikipedia.org/wiki/Epilation#IPL-Technik 178.78.75.150 (talk) 08:34, 5 September 2014 (UTC)[reply]
the article states "The technology utilises a broad spectrum lightsource, with a general spectral range of 515 to 1200 nm. Various cutoff filters are commonly used to filter out lower frequencies" Where as the laser hair removal page in it's section comparison with IPL says "IPL systems typically output wavelengths between 400 nm and 1200 nm. Filters are applied to block lower wavelengths, thereby only utilising the longer, redder wavelengths for clinical applications." These two statements are in direct contradiction with each other. low wavelength is higher frequency and low frequency is high wavelength. Since all citations on this are paid journals i can't tell which is wrong. but the scientist in me is more inclined to believe that shorter wavelengths are being filtered out, as the red end of the spectrum is going to be more useful given that it will not be absorbed by the blood. which means the opening paragraph of this page is wrong. (incidentally i'm not concerned with the different lower and wavelength figures of 400nm and 515nm, as with any broad distribution determining the end of it is not straightforward.)

Agreed. It should say "Various cutoff filters are commonly used to filter out higher frequencies (shorter wavelengths), especially the damaging ultraviolet rays." https://en.wikipedia.org/wiki/Visible_spectrum — Preceding unsigned comment added by 218.101.54.25 (talk) 23:28, 12 October 2016 (UTC)[reply]

I deleted the following sentence. The source provided was a blog post from med spa that markets and sells BBL treatments. Vendor and e-commerce sources are generally to be avoided.
"The differences between IPL and BBL fundamentally come down to operating on different wave lengths. With advances in research, science and light technology, BBL provides more accurate parameters to deliver more targeted and superior results than its IPL counterpart."
I deleted the following sentence. The source provided was a paper by a doctor chronicling her experience using BBL on Asian patients. It made no reference to DNA, skin cells, or "cellular ageing."
The paper is published by Sciton. Sciton manufactures and sells the BBL technology. Vendor and e-commerce sources are generally to be avoided.
"Extensive studies and research have shown that regular BBL treatments not only prevent cellular ageing, but also "turn back the clock", causing the DNA expression of skin cells to revert to a youthful, healthy state."
