Two Essentials Your Skin Needs for Its Best Health
As our skin evolves, it often feels different than it once did—drier, more sensitive, or just harder to keep balanced. And while we’re flooded with advice about what to use, the truth is simple: your skin needs both oil and water to thrive.
Hydration (water) and moisture (oil) are not the same. Without this duo, your skin barrier can’t function at its best.
Another common mix-up? Dryness versus dehydration. Dry skin lacks oil, while dehydrated skin lacks water. If you’re not sure which one you’re dealing with, check out our blog post: Dry Skin vs. Dehydrated Skin: How To Tell The Difference. Understanding this difference—and how oil and water work together—will change the way you care for your skin and help restore its natural vitality.
Why Your Skin Needs Water
Our bodies are mostly made of water—it’s essential for every function, including your skin. Just as we feel sluggish or unwell without hydration, our skin can’t do its job when it’s dehydrated.
As we move through life, hydration levels are impacted by so many factors: hormonal changes, climate, stress, diet, caffeine, alcohol, and even the products we use. If your skincare routine doesn’t replenish water, your skin can quickly slip into dehydration.
Water is critical because it keeps your skin barrier intact. A hydrated barrier protects against stressors like pollution, sun, and wind, while keeping moisture locked deep inside.
How to Keep Water in Your Skin
In your daily ritual, think of hydrators like hyaluronic acid, tremella mushroom, trehalose, ectoin, betaine, saccharide isomerate and floral waters as a refreshing drink for your skin. These water-based ingredients flood your cells with hydration, help your serums and creams absorb better, and reduce trans-epidermal water loss (TEWL)—that sneaky process that leaves skin feeling tight and lined.
Why Your Skin Needs Oil
Our skin naturally produces lipids like triglycerides, waxes, fatty acids, squalene, and cholesterol—collectively known as sebum. This built-in blend keeps skin lubricated, balanced, and protected.
But as hormones shift, our natural oil production slows, and the skin barrier weakens. That’s where plant oils shine. They’re biocompatible with skin and packed with essential fatty acids and antioxidants. Oils provide emollience (softness), occlusion (a protective seal), and barrier support—helping to lock in hydration and accelerate repair.
Internally, eating foods rich in healthy fats and antioxidants helps. Externally, using oils and balms suited to your skin supports the lipid barrier, leaving skin more supple, resilient, and radiant.
Oil & Water: The Yin and Yang of Skincare
Oil and water may seem like opposites, but together they’re the yin and yang of skin health. Hydration replenishes your cells, while oils seal it in and strengthen the barrier.
When both are present, your skin barrier thrives—and so does your glow.
At Skin Alchemy, this philosophy is at the heart of everything we create: oil + water working in harmony to nourish, protect, and restore balance to evolving skin.
