BiON Bacteriostat Cleanser is a low-pH acne cleanser from BiON that controls blemish-causing bacteria without stripping or aggravating sensitive, dry, or rosacea-prone skin. At pH 3.6, it works in the skin’s optimal range for salicylic acid activity, helping keep pores clear while a blend of botanical extracts addresses the inflammation and bacterial imbalance that drive breakouts. The earthy, herbal scent from peppermint, lavender, oregano, and turmeric makes this one of those rare cleansers that people actually look forward to using.
Key Benefits
Controls blemish-causing bacteria at the source At 0.5% salicylic acid and a pH of 3.6, this cleanser penetrates into pores to dissolve excess oil and discourage the bacterial environment that leads to breakouts.
Reduces redness and inflammation Turmeric root extract (Curcuma longa) inhibits 5-alpha reductase activity to help curb sebum overproduction and visibly calm the red, inflamed skin associated with acne and rosacea.
Blocks follicular triggers of irritation Oregano leaf extract (Origanum vulgare) works within the follicle to block interleukin-6 and histamine, two key drivers of the inflammatory response that keeps skin reactive and prone to flares.
Soothes while it cleanses Licorice root extract (Glycyrrhiza glabra) delivers additional anti-inflammatory support, while sodium lauroyl oat amino acids and glycerin maintain moisture so the cleanse never feels tight or depleting.
Gentle enough for sensitive and dry skin The surfactant system, built around sodium C14-16 olefin sulfonate and cocamidopropyl betaine, produces a thorough yet non-aggressive lather that leaves even dry, reactive skin feeling clean and comfortable.
