Microbiome, Probiotics & Gut Nutrition

Skincare products with probiotics worth the hype

Skin is subjected to harsh environmental conditions that favor the growth of primarily gram-positive organisms; resident bacteria are capable of reproducing and are commensal with the host when skin is healthy. When skin is compromised, resident bacteria can become pathogens as is seen in acne and folliculitis. The skin Microbiome is influenced by pH, sebum content, barrier function, and hydration, alterations in skin micro flora play a significant role in conditions such as atopic dermatitis, psoriasis, acne and skin cancer.

Probiotics are live bacterial cultures that, when applied topically, influence the composition of skin micro flora. Acidifying the skin discourages the growth of most pathogens favoring the growth of resident flora. Probiotic strains produce potent antimicrobials such as bacteriocidins, organic acids, and, H2O2 that prevent pathogen adhesion. Lactic acid acts as a natural moisturizing factor and antimicrobial and acts on epidermal and dermal remodeling

Prebiotics are non-digestible plant-based carbohydrates that discourage the growth of pathogens while preserving beneficial bacteria. Prebiotics can be readily incorporated into skin care products and are an excellent alternative to live bacteria. Bacterial cell lysates are also used in cosmetic formulations.
