A cream is distinguished from an ointment primarily by its water-based composition. Creams typically contain a higher proportion of water compared to ointments, which are more oil-based. This water content in creams provides a lighter, more easily absorbed texture that is less greasy than ointments, making them suitable for moisturizing and applying to larger areas of skin. The emulsion of oil and water in creams allows for better penetration into the skin, providing hydration without the heavy occlusive barrier that an ointment tends to create. In contrast, ointments, being more oil-dominant, are used primarily for specific therapeutic purposes, creating a protective layer on the skin that can help retain moisture and promote healing. Understanding this distinction helps in determining the appropriate formulation for various skin treatments and conditions.
