Which ingredient in moisturizer is beneficial for clients with dry skin?

Lanolin is particularly beneficial for clients with dry skin due to its ability to act as an emollient. Derived from sheep wool, lanolin is known for its unique capacity to mimic the skin's natural oils, which allows it to effectively lock in moisture and create a barrier that prevents water loss. This makes it a powerful ingredient in hydrating and soothing dry, flaky, or irritated skin.

While other options can contribute to hydration, lanolin's properties are especially suitable for seriously dry skin conditions. For example, glycerin is a humectant that draws moisture into the skin, aloe vera provides soothing and anti-inflammatory benefits, and petroleum jelly also forms a barrier to retain moisture. However, lanolin stands out for its emollient qualities that specifically cater to those with persistent dryness, making it the most effective choice among the listed ingredients for this particular skin concern.
