Glow Definition
In skincare, fermented refers to ingredients that have been biologically broken down by microorganisms like yeast or bacteria. This process is used to transform natural actives — often plant-based extracts — into smaller or more bioavailable forms, creating new byproducts with different properties than the original material.
Fermented skincare formulas may feature ingredients like galactomyces, bifida ferment lysate, or fermented versions of rice, soy, and ginseng. While fermentation is rooted in tradition (especially in K-beauty), its role in modern routines often centers on skin-friendly support — especially in formulas focused on barrier support, hydration layering, and even tone.

Why It Matters
Fermented skincare fits naturally into routines that prioritize layering, balance, and glow without excess. These formulas often feel weightless but purposeful — designed for skin that craves hydration, calm, and texture refinement without adding noise.
It also ties into skincare cultures that see glow as a lifestyle, not a finish. Fermented ingredients show up in quiet achiever products: essences, milky toners, and light emulsions that support the skin’s natural rhythm and resilience over time.
GLOW TIP Layer fermented essences or milky serums right after cleansing to create a softened base for the rest of your glow routine — especially if your skin runs sensitive, reactive, or easily thrown off by too many actives.
Why We Love It For Glow
Fermented skincare is glow without the performance. It doesn’t rely on shimmer, acids, or heavy actives — it’s quiet, intuitive, and builds skin harmony over time. That makes it especially powerful in routines where you want radiance that feels rooted, not rushed.
We love how seamlessly these formulas layer, especially in routines built around hydration layering, barrier support, or skin resilience. They’re the in-between step that makes the rest of your skincare feel more connected.

FAQ
What makes fermented skincare different from regular skincare?
Fermented skincare focuses on ingredients that have been transformed through natural fermentation, often making them gentler, more compatible for layering, and better suited for routines that prioritize skin balance and hydration.
Is fermented skincare good for sensitive skin?
It’s often a quiet favorite in sensitive routines. Many fermented formulas skip heavy actives and instead lean into hydration and barrier-friendly ingredients that support skin without triggering disruption.
Do fermented ingredients work well with actives like retinol or acids?
Yes — they’re typically used to buffer stronger actives or restore balance in glow cycles. Apply fermented products first to help soften the impact of stronger treatments layered later.
