Moisturisers are formulations combining emollients, humectants, and occlusives that improve skin hydration, restore barrier function, and reduce transepidermal water loss. They are foundational skincare products used both alone and as vehicles for active ingredients.

Allergic contact dermatitis | Uncommon | Triggered by specific ingredients such as fragrances, lanolin, or preservatives. |
