What is a common method used for achieving skin hydration?

Using hyaluronic acid serums is a common method for achieving skin hydration because hyaluronic acid is a powerful humectant. This means it has the ability to attract and retain moisture from the environment and deeper layers of the skin. Hyaluronic acid can hold up to 1,000 times its weight in water, making it an effective ingredient in hydrating serums. When applied to the skin, it helps to plump and smooth the skin's surface and can contribute significantly to an overall radiant and healthy complexion.

In contrast, while oil-based serums and heavy creams can also contribute to hydration, they primarily provide a barrier that locks moisture in rather than actively drawing moisture to the skin. These methods can be effective under certain circumstances, but they do not have the same hydrating properties that hyaluronic acid offers.

Steaming treatments can help open up the pores and may temporarily increase moisture but do not directly hydrate the skin in the way hyaluronic acid does. They are more beneficial for cleansing and preparing the skin for treatment rather than being a primary source of hydration.
