Rosacea -- resting facial blood flow is incredibly high

[drnase]

Hi Group,

I just wanted to re-emphasize the importance of abnormal blood flow in rosacea and how laser treatment and upcoming products like the constrictor SansRosa are helpful.

In this one study, measurement of facial blood flow of rosacea sufferers compared to non-rosacea sufferers is off the charts: Normal blood flow is very low and tightly controlled. An increase of resting blood flow by 2 times is incredibly high and pathologic. This study found rosacea affeced skin was 3 to 4 times higher than control subjects. In microvascular physiology, this is so high that it would ensure damage to blood vessels and the dermis.

Rosacea: a study of clinical patterns, blood flow, and the role of Demodex folliculorum.

BACKGROUND: Rosacea is a common facial eruption that has various clinical presentations. OBJECTIVE: We studied blood flow in lesional skin and explored the role of Demodex folliculorum in patients with rosacea. METHODS: A survey of clinical presentations was made in 108 patients with rosacea. Facial blood flow was studied by laser-Doppler flowmetry. The presence of Demodex was determined by microscopy of skin samples. RESULTS: The sex incidence was equal. The incidence peaked in the fourth and seventh decades of life. Lymphedema was common and was seen in 26 patients. Rhinophyma was present in 15 patients, mostly men. Eleven patients were black, an unexpectedly high number. Laser-Doppler flowmetry showed that lesional blood flow was three to four times that of control subjects. CONCLUSION: The findings indicate that the papillary dermal vasculature is dilated in rosacea. Demodex may be present.

so, are the facial blood vessels really at fault, or is our body just pumping all of this blood into the face when we are not in a resting state? It would seem to me that the facial blood vessels are normal, but become damaged due to all the blood flow. Perhaps whatever is sending all this blood to the face in the first place is the real problem, and there is no genetic issue with out blood vessels at all, at least in the face.

Awesome question. Each organ has its own mechanisms to control blood flow. So there can be normal blood flow throughout the rest of the body, but if the facial feed vessels open up, then just the face will have higher blood flow. I do remember in one article where they measured the forearm blood flow and found it normal while the face was outrageously high.

Just like you said though, the sympathetic nervous system does control many organs, so when that is activated many organs change their blood flow -- some constrict like heart blood vessels, and some dilate like the kidneys, liver, stomach, etc. Thanks for that question.

So might another possible solution be to clamp or surgically decrease the flow of the feed vessels, and cut off the blood flow at the source, rather than zap the small capillaries within the face?

I've been looking on the web for a diagram of facial blood vessels, but I can't find squat! Does anybody have a link to such a diagram?

I would love know know if we can surgically cut off the feed vessels to the face, say, through the inner mouth, so that the outer facial skin is not scarred. Would this be possible?

Thanks.

Yea guys really, how do we decrease blood flow to the face enough to stop the redness?

I am afraid there is no easy answer. Lasers can perhaps help and Dan has been explaining how vitamin D 3 might help in this area.

So theres a possibility it Vit. D could help with blood flow?
