Glow Definition
Peptides are short chains of amino acids that serve as the foundational components of proteins like collagen, elastin, and keratin — all of which play structural roles in skin. Peptides in skincare are lab-formulated to mimic or support certain skin functions, depending on their sequence and size. While they don’t act as actives in the same way as acids or retinoids, they’re often used to complement glow routines focused on hydration, texture, or skin resilience.
Not all peptides serve the same purpose — some are designed to help buffer the skin against dryness, while others are included in formulas meant to support a more balanced barrier. Their gentleness makes them a go-to in serums, moisturizers, and treatments formulated for layering. Within a glow-focused routine, peptides can offer a consistent, low-interference layer that helps support the skin’s visible bounce and overall suppleness over time.

Why It Matters
Peptides in skincare show up in routines that aim to support overall skin function, especially when glow is approached as more than just surface-level radiance. While they’re often featured in moisturizers and serums, their real role is in rounding out a routine that already prioritizes hydration, barrier care, and consistency.
Because peptides can be formulated in many ways, they tend to show up in products designed for daily use — especially in routines that emphasize prevention, replenishment, or recovery. Their presence reflects a broader shift toward ingredient layering that works in rhythm with skin rather than trying to push dramatic overnight changes.
GLOW TIP Apply peptide serums after cleansing and before heavier moisturizers to help them layer seamlessly and support your skin’s natural rhythm.
Why We Love It For Glow
Peptides offer a kind of quiet utility in skincare — they’re not trend-driven, but they consistently show up in routines focused on long-term skin resilience. Their versatility makes them ideal for routines that prioritize layering and support without overload.
What makes peptides stand out in glow routines is how well they pair with both hydrating and barrier-focused products. Whether you’re rebuilding after exfoliants or just streamlining a simple routine, peptides add a supportive layer that feels intentional, not extra.

FAQ
What do peptides do in skincare routines?
Peptides in skincare help support the skin’s surface by acting as building blocks that complement ingredients like ceramides, hyaluronic acid, and fatty acids. They’re often used to add structure to glow routines, especially when layering lightweight serums and moisturizers.
Are peptides better in a serum or moisturizer?
Peptides can be found in both serums and moisturizers, but the best option depends on your overall routine. Serums may allow for more targeted layering, while moisturizers with peptides offer a more cushioned, sealing effect — ideal for barrier support or nighttime routines.
Can I use peptides with retinol or exfoliants?
Yes, peptides are generally considered compatible with a wide range of skincare ingredients. In glow routines, they’re often paired with retinoids or exfoliants to balance intensity and introduce support between active days.
