What is the purpose of a moisturiser?

The primary purpose of a moisturiser is to prevent dehydration of the skin. Moisturisers are formulated to provide an external layer of hydration, which helps to lock in moisture and create a barrier that protects the skin from environmental factors. When the skin is well-hydrated, it maintains its elasticity, suppleness, and overall health.

While other benefits such as improving skin texture, enhancing radiance, and reducing the appearance of wrinkles can also be associated with the use of moisturisers, they primarily serve to combat dryness. Dehydrated skin can lead to various issues, including flakiness, dullness, and increased sensitivity, making moisture retention critical for skin health. Thus, ensuring that the skin stays hydrated is foundational to achieving other skin-related goals.
