Hydration vs. Moisture: The Secret to Plump, Dewy Skin

This is one of the most common points of confusion in skincare, but understanding the difference is key to achieving that coveted "glass skin" look.

Hydration is about attracting water to your skin cells. It makes your skin look plump, supple, and healthy. Ingredients like hyaluronic acid and glycerin are humectants, meaning they draw water from the air and deeper skin layers to the surface. If your skin feels tight or looks dull, it’s likely dehydrated.

Moisture is about creating a protective barrier to prevent water from escaping. It keeps your skin soft and smooth. Ingredients like ceramides, fatty acids, and squalane are emollients and occlusives that lock in hydration and repair your skin's natural barrier. If your skin feels rough, flaky, or dry, it needs moisture.

To get the best results, you need both. Hydrate with a good toner or essence, then apply a moisturiser to seal it all in. This layering technique is a core principle of K-beauty and ensures your skin stays balanced and resilient.
