The Pro Balance Biotics Toner by Dr. Ceuracle is a toner that strengthens the skin barrier, which is essential for maintaining skin health. Enriched with G.Fer-kefir and a 5 Probiotics Complex to support the skin's microbiome and reinforce its natural barrier, this lightweight toner helps restore moisture loss and eliminate dull, tired-looking skin. Infused with biomimetic water—a blend of mineral water, L-theanine, glutathione, and milk lipids that mimics the skin's natural hydration—this toner acts as a quick-absorbing thirst quencher, hydrating, plumping, and softening the skin. Incredibly lightweight with a soft and comforting texture, its probiotic-rich formula is also gentle enough to help soothe your skin if you've overused acids or active ingredients in your skincare routine.
