Ceramides are critical building blocks of your skin barrier, which keeps moisture in while protecting against environmental damage like UV radiation and free radicals. As the body produces less, it becomes more susceptible to dry, aging skin before its time.

Dry skin occurs when the skin lacks sufficient moisture and essential oils to maintain normal hydration levels. This can be caused by harsh weather, drying substances or practices (e.g., excessive handwashing), and internal factors like aging and genetics.

A healthy skin barrier protects against environmental aggressors such as pollutants, toxins, and bacteria, while also preventing excessive water loss. It can deteriorate due to age, stress, or extreme weather, leading to dry skin, irritation, as well as fine lines and wrinkles.

As we age, the body produces less ceramides and the skin grows thinner. This makes it less effective at holding moisture, so it’s more susceptible to dryness - leading to a parched and less elastic look and feel.
