Barrier creams are topical substances applied to the skin to supply a protective layer or “barrier” against potential irritants or harmful substances. They’re often used in various fields such as healthcare, industry, and cosmetics.
Barrier creams can:
- Help protect the skin from harmful irritants in the environment such as chemicals, acids, alkalis, oils, and solvents, often used by people whose jobs expose them to these irritants (e.g., healthcare workers, cleaners, mechanics).
- Prevent moisture-associated skin damage by forming a barrier against bodily fluids like sweat, urine, or feces. This is especially relevant for patients with incontinence or newborns who wear diapers.
- Assist in managing certain skin conditions, like eczema or dermatitis, by reducing water loss from the skin and providing a layer of protection from allergens or irritants.
- Protect the skin from extreme weather conditions (like wind or cold), preventing chapping and drying.
In skincare and cosmetics, barrier creams often contain ingredients like lanolin, zinc oxide, petroleum jelly, silicone, or dimethicone. They may also contain moisturizing agents like glycerin and hyaluronic acid to promote skin hydration. Barrier creams should be used as directed, and individuals with sensitive skin or known skin allergies should seek advice from a healthcare provider before use.
