Dry skin produces too little oil and feels dry all over, often on your body too. Dehydrated skin loses water: it feels tight and dull, but can also be shiny. If your skin feels tight all year round, choose rich creams and a face oil. If it feels tight but sometimes oily, start with the hydration duo and a lighter cream.

Hot water and foaming cleansers strip your skin of its natural oils. Shower with lukewarm water, cleanse your face with a milk or oil instead of foam, and moisturize within three minutes of drying off to lock in moisture before it evaporates.

The Hydrating Serum provides pure, deep hydration with hyaluronic acid. The Jelly Serum also hydrates, but adds prebiotics that support your skin barrier, in a light gel texture. If you're in doubt: barrier damaged or easily irritated, choose the Jelly; just thirsty, choose the Hydrating.

Both are possible. As a last step after your cream, it locks everything in, ideal for the evening. For very dry skin, you can also mix it with your cream. Oil always comes as the last skincare step; only your SPF comes after it in the morning.

Less than you think. Drinking water is healthy, but your skin primarily dries out due to moisture loss at the surface: a weakened barrier, heating, hot showers. That's why applying creams works better than drinking water: hydration in, ceramides on.

Exactly then. Cold air and heating make every skin drier. You can scale up in winter: the Nourishing Rich Cream instead of your day cream, and the oil more often on top.
