In the recent years there has been a growing interest, from both the medical community and the patients, in the effects of probiotics on the course of seborrheic dermatitis (SD). In a previous post we have discussed the effects of Vitreoscilla filiformis probiotic applied to the skin. A double-blind study1 involving 60 patients with SD showed a reduction of itching, erythema and scaling. In two other posts (this and this) we discussed how clinical studies involving the oral administration of respectively ST112 and E. coli Nissle3 probiotics demonstrated a significant reduction in SD symptoms. These examples confirm the benefits of using various strains of probiotics when treating SD. Today, we’ll…

V. filiformis probiotic on the skin improves seborrheic dermatitis
Probiotics – the good bacteria living in our guts – have a strong impact on the health of our skin. We have previously discussed two specific bacterial strains that have been scientifically shown to be efficient in treating seborrheic dermatitis (see the articles on lactobacillus paracasei and E. coli Nissle). In both cases the treatment consisted of orally ingesting the bacteria as a dietary supplement. However, starting around 2005, scientists have been investigating the effects of applying probiotics directly to the skin (instead of ingesting). Their results show that such an approach can treat various skin conditions, such as acne, rosacea, yeast and bacterial infections, psoriasis, and dermatitis1. Clinical study…

Seborrheic dermatitis significantly improved by E. coli Nissle probiotic
In a previous post we have discussed probiotics (bacteria living in our gut) as a promising treatment for seborrheic dermatitis. That post mainly focused on the l. paracasei bacterium and its positive effects. In this post I want to briefly discuss a recent study1 that shows that oral ingestion of another probiotic, known as Escherichia coli Nissle, is very effective for treating seborrheic dermatitis. Facial dermatoses, including seborrheic dermatitis, are often associated with gastrointestinal diseases2. The mechanism by which intestinal diseases induce skin issues is not known. It is known however that intestinal-borne dermatoses are accompanied by a shift of gut bacteria population towards more aggressive types. Due to their…

Probiotics promise a cure for seborrheic dermatitis!
Seborrheic dermatitis (SD) is often seen as a condition that should be treated locally, directly at the surface. On this blog we have discussed a number of such treatments: sea salt, selenium sulfide (in Selsun), zinc oxide and zinc sulfate (in Avene Cicalfate), zinc pyrithione (in DHS Zinc Shampoo), and piroctone olamine (in Sebclair/PromiSeb). These products can definitely be very efficient and many people have reported great results. However, products applied topically (on the surface of the skin) only affect the top layers of the skin. And, as we know, those layers are shedding away constantly. To achieve positive and permanent improvements, the skin needs to be affected from the…
