Demodex and Rosacea


Picture from "Demodex, an inhabitant of human hair follicles, and a mite which we live with in harmony" by M. Halit Umar

Rosacea flareups can be alleviated in minutes with the FSCAN. Some rosacea is associated with a Demodex infection, a common mite. I do not agree with Umar that we live in harmony with this parasite, as it affects bodily functions even when there are no observable symptoms. You are likely to feel better with this parasite gone.

In 2004, I suggested FSCAN users should try 892, 753, 558, 345, 176454. 285526, 385497, 456777. The lower frequencies are Rife octaves which can be used on machines like the EM6+ which only go up to 10000HZ. The higher frequencies are four life cycle stages of the parasite. All must be eliminated simultaneously or the infection will simply grow back from remaining larvae or eggs. Periodic treatment every few weeks may be needed to prevent flareups, although newer technologies and better frequencies can clear this parasite for extended periods. Also, I have seen rosacea infections caused by parasites other than this one, so these frequencies may or may not be the right ones.

Since this item was first published in 2004, there have been major upgrades in both technologies and frequencies for dealing with demodex. Those interested should become a subscriber to Frequency Foundation and/or request a consultation.

There is an extensive literature on Demodex in PubMed. See for example:

BACKGROUND: The cause of rosacea is unknown; among other factors a causative role has been postulated for the hair follicle mites Demodex folliculorum and Demodex brevis. OBJECTIVE: Our purpose was to compare the population density of Demodex mites in facial skin of defined categories of patients with rosacea with control subjects. We also assessed the impact of tetracycline therapy on the mite population. METHODS: The population density and distribution of Demodex mites were studied in the facial skin of 42 patients with rosacea and 42 age- and sex-matched control subjects. Mites were counted in measured skin surface biopsy specimens obtained from six standard facial sites with cyanoacrylate glue. RESULTS: The mean mite count was 49.8 (range 2 to 158) in patients with rosacea and 10.8 (range up to 97) in control subjects (p < 0.001); the highest density of mites was found on the cheeks. A statistically significant increase in mites was found in all subgroups of rosacea, being most marked in those with steroid-induced rosacea. Mite counts in patients with rosacea before and after a 1-month course of oral tetracycline showed no significant difference. CONCLUSION: Increased mites may play a part in the pathogenesis of rosacea by provoking inflammatory or allergic reactions, by mechanical blockage of follicles, or by acting as vectors for microorganisms.

The hair follicle mites Demodex folliculorum and Demodex brevis and their role in the pathogenesis of rosacea have been the subject of much debate in the past. We studied the prevalence of Demodex mites in facial skin biopsies obtained from 80 patients with rosacea, 40 with facial eczematous eruption and 40 with lupus erythematosus discoides. The mite prevalence in the rosacea group (51%) was significantly higher than in the rest of the study population (eczema 28% and lupus discoides 31%). Demodex mites were found on all facial sites. The most infested areas in the whole study group were the forehead (49%) and the cheeks (44%). Males were more frequently infested (59%) than females (30%). We did not find any significant difference in mite counts of infested follicles between rosacea and the control group. A lympho-histiocytic cell infiltration was seen around the infested hair follicles. Our results suggest that Demodex mites may play a role in the inflammatory reaction in acne rosacea.
