Lactobacillus
Ingredient Info
Lactobacillus is a live beneficial bacterium (probiotic) that naturally exists on healthy skin and in the gut. In skincare products, it's included to help restore and maintain a balanced skin microbiome, which supports the skin's natural defenses and may reduce inflammation.
Benefits
- May help restore healthy skin microbiome balance
- Supports skin's natural defense mechanisms
- May help reduce inflammation associated with certain skin conditions
Potential concerns
- Limited evidence for topical application in skincare products
- Efficacy depends on product formulation and bacterial viability
- People with compromised immune systems should consult a doctor before use
Science: Research shows Lactobacillus levels are reduced in inflammatory skin conditions like psoriasis, and oral probiotics show promise in supporting skin health. However, most robust evidence concerns oral/gut probiotics and vaginal health; peer-reviewed data specifically supporting topical Lactobacillus in cosmetic skincare products remains limited.
