LED (light emitting diode) treatment for rosacea? Part 1 of 2

This is part one of a two-part post on LED treatment for rosacea. I have asked David C, who posts regularly on rosacea forums online, to share his experiences with LED treatment for rosacea for part one. Part two, coming in a few days, will look at what if any other evidence there is to [...]

Rosacea and topical calcium dobesilate

The full paper by P Cuevas et. al is now online as a PDF download:
Theraputic Response of rosacea to Dobesilate
We have blogged about rosacea and topical dobesilate before, here.
I will post more analysis when I’ve read the paper in full, so please check back.

Dobesilate: Topical angiogenesis inhibitor for rosacea

Now that the full paper is published online, this post looks in more detail at topical dobesilate. You can see our previous dobesilate post here, which is also worth reviewing.
This is a paper describing a case study of person’s response, so that needs to be kept in mind when looking at the results. Here is [...]

New study on red and blue light for acne

A new study has been published on red and blue light (using LED’s as the non-thermal light source). The study does not use a control group or try and differentiate between red and blue light, and there is even some microdermabrasion thrown in for good measure — so not a terribly rigorous, scientific approach, [...]

Migenix develops CLS001 (formerly MX-594AN) as a topical treatment for rosacea

Migenix, using technology licensed and being developed in partnership with Cutanea Life Sciences, is developing a new topical product for rosacea. It looks to be an anti-inflammatory/anti-microbial (so may be beneficial for those rosacea sufferers with acne), based on "cationic antimicrobial peptides". Phase II trials are due to be completed in 2007.
Migenix’s financial [...]

Dr. Patrick Bitter’s phenyl-epinephrine rosacea patent

Dr. Bitter (creator of the "PhotoFacial" protocol) has submitted a patent application for the use of a topical constrictor, post-IPL treatments, or as a cosmetic lotion (to reduce redness). Most patents don’t result in commercial products/treatments being developed, but interesting nonetheless.

Zinc sulfate as a treatment for rosacea

Here’s an interesting one. A double-blind, placebo-controlled study on zinc sulfate (100mg three times a day) as a naturopathic rosacea treatment, by the University of Baghdad, Iraq. Good results and minor gastric side-effects in some patients (for what it’s worth, my personal experience with zinc is that I suffer gastric problems). The abstract [...]

Treating rhinophyma with tamoxifen?

An interesting laboratory study that speculates on the possible treatment of rhyinophyma (red, bulbous nose of rosacea, often with excess tissue) with the "breast cancer" drug, tamoxifen (also rarely used to treat retroperitoneal fibrosis).
A number of studies appear to have suggested that fibrosis (caused by overexpression of the fibrogenic protein TGF-beta 2?) is implicated in [...]

Clinuvel (epitan / melanotan) completes small Phase II trial - "ample challenges ahead"

Clinuvel (was Epitan) has completed a small Phase II trial with patients suffering from Polymorphous Light Eruption (PLE). This is part of their strategy of ensuring targeting relevant dermatological diseases that benefit from increased sun protection via melanin.
"We have made a significant step forward in the development of CUV1647, but there are ample challenges [...]

IPL (photoderm) and cancer? No link in animal experiments

A recent study looks at the occurrence of carcinogenesis (cancer) in animals exposed to Intense Pulsed Light. Since the introduction of IPL, many have wondered whether there could be the potential to increase likelihood of skin cancer. This is only one step in addressing that question, but an important one.
Carcinogenesis related to intense [...]

Effects of IPL on different size blood vessels (mathematical modelling)

An interesting study that attempts to model effects of IPL on different size blood vessels. Worth noting that small vessels were the most difficult to effectively raise the temperature of to levels for successful coagulation.
Abstract:
"Lasers Surg Med. 2006 Oct 25;
The effects of intense pulsed light (IPL) on blood vessels investigated by mathematical modeling.

Why permanent facial redness can be hard to treat - lessons from the paper on IPL modelling

One of the authors, Gal Shaferstein Ph.D, was kind enough to send me a copy of the paper I blogged about last week, "The effects of intense pulsed light (IPL) on blood vessels investigated by mathematical modeling"… Here are some of my observations an an interested observer (but not a doctor!)
Re-iterates what I have read [...]

IPL and cancer/DNA damage - another study raises questions

New study looks at whether repeated non-ablative IPL or laser exposure causes DNA damage (which may lead to cancer) in an animal model.
No tumors were caused or any health affects noted in the mice during the 6-month study, but expression of two potential "markers" of DNA damage were increased - particularly with 1320 Nd:YAG treatments.
The [...]

New ideas for protecting the face and nose during winter

New protective garments that I’ve been experimenting with recently have revolutionised what outdoor activities I can take part in during winter, especially long-distance hiking which previously I avoided like the plague during the colder months.
I wanted to share my experience for anyone else whose face and nose turn red and hurt during and after cold [...]

Taking accurate photos pre/post IPL treatment to measure skin redness

A new paper deals with how to accurately take before and after pictures and maintain consistant colours. Before and after photos of rosacea sufferers or those with facial redness are often of poor quality and dubious in terms of reliability, indeed sometimes it may be deliberate "marketing" in order to try and entice [...]

SansRosa / COL-118 Phase II "highly positive"

COL-118, Collagenex’s topical (i.e. "cream" based) treatment for the redness and flushing associated with rosacea has had "highly positive" results in their Phase II studies. I was recently wondering what was happening with COL-118 and had started to suspect it was not progressing so this is suprising and pleasing news to me.
They are expecting [...]

New study: "Successful Treatment of the Erythema and Flushing of Rosacea"

Interesting sounding new study:

Title:
Successful Treatment of the Erythema and Flushing of rosacea Using a Topically Applied Selective {alpha}1-Adrenergic Receptor Agonist, Oxymetazoline.

SansRosa, now aka COL-118

From a Collagenex press release:
"CollaGenex is also developing COL-118, utilizing the technology acquired in the SansRosa acquisition, as a preclinical topical compound for the treatment of redness associated with rosacea and other skin disorders. "
Under the 2006 financial guidance section:
"Research and development expenses: R&D expense is expected to be approximately million and is
