Probiotics rebalance the skin microbiome by increasing beneficial bacteria and reducing the inflammation-causing strains linked to breakouts, redness, and conditions like acne, eczema, and psoriasis. They also strengthen the skin barrier, helping skin retain moisture and resist environmental stressors.

Exponent uses fermented microorganisms that are microencapsulated for stability and preserved in powder form until activation. Microencapsulation in a non-aqueous format protects the live cultures from degrading before they reach your skin, ensuring you get the full benefit of the active cultures with every dose.

No. Clear Comeback is formulated and clinically tested on sensitive skin types with no irritation. Probiotics work with your skin's natural biology rather than disrupting it, making them suitable for daily use from the start.

Yes. Probiotics pair well with most actives including CoQ10, Hyaluronic Acid, and Vitamin C. If layering with Retinol, alternate nights rather than using both simultaneously, as the Willow Bark in Clear Comeback may increase sensitivity in combination with retinol.

Probiotic serums are particularly effective for acne-prone, sensitive, and reactive skin types, as well as anyone whose barrier has been compromised by harsh actives or over-exfoliation. They are also well suited as a daily maintenance step for anyone focused on long-term skin health, enlarged pores and congestion, and microbiome balance.

With consistent use, probiotic serums help reduce breakout frequency, calm redness and inflammation, reduce blackheads and the look of enlarged pores, and strengthen the skin barrier over time. Skin typically appears calmer and more balanced within the first few weeks of daily use.
