Hydration vs. Moisturisation: Understanding the Difference for Healthier Skin

Hydration and moisturisation are two words that pop up repeatedly regarding skincare. They're used interchangeably, but they target different skin needs. 

Hydration attracts water to skin cells, while moisturisation seals water to prevent dryness. Mastering the balance between the two is the key to achieving healthy, radiant skin. Let's examine each of these steps and explore some Korean skincare products that excel at both.

Hydration: feeding skin's thirst

Hydration in skincare is all about supplying water to the skin—think of it as giving your skin a refreshing drink.

Hydrating products contain humectants to draw water into the skin. Key humectants include hyaluronic acid, glycerin, and aloe vera—all commonly found in K-beauty products. These ingredients boost the skin's hydration level, making it plumper, softer, and better able to fend off environmental stressors.

Signs your skin needs hydration

• Tightness: Especially after washing, your skin feels tight, dry, or stretched.
• Fine Lines: Lack of hydration makes fine lines more pronounced.
• Dullness: Dehydrated skin often looks dull and tired.

Moisturisation: locking in the hydration

Once the skin has absorbed water, it's time for moisturisation. This step uses occlusives and emollients to lock in hydration and prevent water from evaporating.

While hydration fills skin cells with water, moisturisation creates a protective barrier on the skin's surface. It locks in all nourishment ingredients so that your skin stays hydrated longer.

Moisturisers contain oils, ceramides, and other rich ingredients that strengthen the skin barrier, essential for preventing moisture loss.

Signs your skin needs moisturisation

• Flakiness: Dry, flaky patches signal a need for moisture.
• Rough Texture: Moisturisers smooth the skin's surface, making it feel softer.
• Sensitivity: Lack of moisture can lead to a compromised barrier, making skin more sensitive.

How hydration and moisturisation work together

Hydration and moisturisation complement each other perfectly. Balancing both is crucial for healthy, resilient skin. 

Hydrate first, then moisturise. By layering a hydrating serum or essence before applying a moisturiser, you ensure that the water absorbed by your skin doesn't evaporate, keeping your skin soft and luminous for longer.
