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

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.
