A Personalised Guide to Moisturising and Hydrating Skin

"Hydrating" and "moisturising" are often used interchangeably, but they solve different problems — and knowing the difference is the key to a comfortable, healthy-looking complexion.

Hydration vs. moisture

  • Hydration adds water to the skin — the job of humectants like hyaluronic acid.
  • Moisture seals that water in and reinforces the barrier — the job of emollients and occlusives.

Most skin needs both: a humectant to draw water in, and a moisturiser to keep it there.

Match it to your skin

  • Dry skin — richer creams like Cream Extreme and layered hydration.
  • Oily skin — lightweight, non-comedogenic hydration (don't skip it).
  • Combination — adjust textures by zone.

Hydration that lasts

The Environmental Age Defense Moisture Cloud hydrates and protects against the environmental stress that dries skin out. Find more in our Dryness & Dehydration collection.

Frequently asked questions

Can skin be oily and dehydrated at once?

Yes — that's very common. Add a water-binding humectant rather than only heavier creams.

Do I need a separate hydrating serum and a moisturiser?

Ideally yes: the serum adds water, the moisturiser locks it in. In a pinch, a good moisturiser alone still helps.
