Glow Definition
Hydration in skincare refers to the process of increasing the skin’s water content, often through the use of humectant ingredients that attract and retain moisture. Unlike moisture (which relates to oils and lipids), hydration is all about replenishing water to help skin appear plumper, smoother, and more balanced.
Utilizing hydration in skincare is a foundational step in nearly every skincare routine — especially when skin feels tight, looks dull, or struggles with product absorption. Hydration doesn’t just support softness or glow; it helps create the ideal conditions for other ingredients to do their job more effectively.

Why It Matters
Hydration plays a central role in how your skin functions — and how it looks. When water levels in the skin are low, you may notice tightness, patchy absorption, or an overall lack of glow, even if you’re using “moisturizing” products. That’s because hydration sets the stage for everything else. Without enough water, the skin barrier struggles to stay supple, and actives like exfoliants or retinoids may feel harsher than they are.
Supporting hydration helps the skin stay more receptive to what you apply next. Whether you’re layering on barrier-repair ingredients or reaching for antioxidant serums, the right hydration layer helps those formulas spread evenly and absorb more predictably. It’s the difference between a routine that sits on top of your skin — and one that syncs with it.
GLOW TIP Layer your humectants — like hyaluronic acid or glycerin — while your skin is still damp, then seal them in with a moisturizer or oil to keep that hydration from evaporating.
Why We Love It For Glow
Hydration is what gives skin its bounce — not just the look of moisture, but the feel of energy beneath the surface. When your skin is well-hydrated, it reflects light more evenly, absorbs products more effectively, and feels more resilient from within.
Hydration for glow is foundational. It doesn’t ask for attention but quietly elevates everything else you do in your routine — from barrier repair to exfoliation. Without it, glow just doesn’t land the same.

FAQ
What is the difference between hydration and moisture in skincare?
Hydration refers to the water content within your skin cells, while moisture involves sealing that hydration in with ingredients like oils or occlusives. Think of hydration as the drink and moisture as the barrier that keeps it from evaporating.
How can I tell if my skin is dehydrated or just dry?
Dehydrated skin may feel tight, dull, or papery—even if it’s producing oil. Dry skin, on the other hand, lacks oil and often shows flakiness or rough texture. It’s possible to have both at once, which is why layered care is often key.
What ingredients should I look for to boost hydration in my routine?
Look for humectants like glycerin, hyaluronic acid, and aloe vera. These ingredients draw moisture into the skin and can be layered under your moisturizer for deeper hydration benefits.
