Saccharomyces improves acne treatment
We explored how Saccharomyces cerevisiae Hansen CBS 5926, also known as Perenterol, affects acne in a randomized, double-blind study with 139 participants.
The study revealed impressive results: approximately 74.3% of those treated reported good or very good outcomes, compared to just 21.7% in the placebo group.
More than 80% of patients who received the yeast preparation saw substantial improvement or healing, while only 26% in the placebo group experienced similar results.
Notably, there were no significant side effects reported in either group, making this treatment an increasingly popular option for those battling acne.

Cured cystic acne
20 people found this helpful
This product legitimately cured my adult cystic acne, which I had battled for years. I had large cysts on my back and chest. I stopped all other supplements and took these three times a day for a month, resulting in a cure. After stopping, the acne returned, but restarting the regimen fixed it again. I believe the issue stemmed from low-dose antibiotics in high school for regular puberty acne, which had altered my gut microbiome. This product resolved my acne and several digestive issues.

Decreased acne

I really liked this product. I took it for a month and ordered more. It kills the bad bacteria causing my acne. It’s similar to Enterol, but I’m unsure if Enterol is for long-term use.
