Probiotics are living bacteria that have a beneficial effect when applied topically to the skin. Probiotics are an emerging new trend in skin care. When applied topically they can strengthen the skins defence mechanisms and make the skin less sensitive. Probiotics can act like a shield over the skin protecting it from external aggression.
Probiotics have a calming effect on the skin, which makes it great for conditions ranging from acne to rosacea to general sensitivity. Certain probiotics can protect against UV damage occurring from sun exposure and strengthen the skin’s immune system.
In patients with acne and rosacea, living microorganisms on the skin are recognized as foreign by the body’s immune system. The immune system springs into action to counter this potential threat resulting in the inflammation, redness, or bumps common in these skin conditions.
Probiotics applied topically sit on the skin’s surface and prevent the skin cells from seeing the bad bacteria and parasites that can cause this immune system response. This is known as “bacterial interference,” as probiotics protect the skin and interfere with the ability of bad bugs (or bacteria and parasites) to provoke an immune reaction.
Sometimes the substances produced by probiotics have antimicrobial properties, meaning they can create holes in bad bacteria and kill them. Similar to the way antibiotics work in the treatment of acne and rosacea, probiotics can help fight harmful bugs from triggering inflammation
When certain types of probiotics are placed in contact with skin cells, they calm the parts of the cells that may want to react to the presence of bad bacteria that they see as a threat. These healthy signals produced by the probiotics stop the skin cells from sending “attack” messages to the immune system that result in flares of acne or rosacea.
Inflammation in the body is generally accompanied by an imbalance in microflora. That imbalance triggers an immune response from the resident bacteria, which counteracts the inflammation.
