Live Probiotic Serum 7.5 / 10

The full breakdown

Four Lactobacillus species at 1 billion CFU/ml make this a genuinely innovative microbiome approach — Esse cites a German Dermatest study showing +16% firmness in 28 days as a brand-supplied claim. Premium, and the clinical evidence base is still niche.

Ingredient breakdown

• Live Lactobacillus Cultures
  Moderate evidence

  Commonly used to help rebalance the skin microbiome and calm inflammation. A GRADE systematic review and meta-analysis of randomized controlled trials found Lactobacillus-based microbiome therapy effective for acne vulgaris with a favorable safety profile, and a separate randomized double-blind trial found Lactobacillus-derived postbiotics improved a chronic inflammatory skin condition.

• Prebiotics
  Limited evidence

  Commonly used to help support a balanced skin microbiome. A review of microbiome-modulatory treatments for acne found some evidence supporting probiotics/prebiotics/synbiotics, while honestly noting most existing studies are small, in vitro, or animal-model based rather than robust human clinical trials; a separate 12-week clinical trial found oral probiotic and prebiotic supplementation improved psoriasis disease activity measures alongside standard topical therapy.
