Dry skin and and dehydrated skin are often interchanged or confused. But there is a big difference. 

Dry skin lacks sufficient oils (sebum) to keep the skin moisturized, whereas dehydrated skin is a temporary state where the skin lacks/loses more water. 

Dehydrated skin has the ability to come and go, depending on the environmental factors (eg. season), whereas dry skin is considered a skin type. 

Hydrating ingredients literally add hydration—water—into the skin:

> Hyaluronic acid    > Urea

> Glycerin    > Lactic acid 

> Aloe vera    > Squalane

> Sodium hyaluronate

and more

In order for hydrating serums to be effective, they require that you layer with a cream/lotion to lock in the water.

Save this post so you can refer back when you need it. 

What are your favourite hydrating serums? Or which product have you used with one or more of these?
