The ingredients and methods that help lock in moisture for dry skin include occlusives such as petrolatum, dimethicone, and shea butter. These form a protective barrier on the skin to prevent water loss. Additionally, applying moisturizer immediately after bathing or washing, when the skin is slightly damp, helps trap moisture effectively. Moisturizers containing humectants like hyaluronic acid and glycerin pull moisture to the skin surface, while emollients like ceramides smooth and soften the skin. Creams and ointments tend to be more effective than lotions for locking in moisture on dry skin due to their thicker consistency.

Key Moisture-Locking Ingredients

• Petrolatum: seals in moisture by creating a very effective barrier.
• Dimethicone: a silicone that forms a breathable barrier.
• Shea butter: a rich emollient that soothes and locks moisture.
• Ceramides: natural lipids that help restore the skin barrier.
• Glycerin and hyaluronic acid: humectants that draw moisture to the skin.

Best Practices

• Apply moisturizer immediately after bathing while skin is still damp.
• Use thicker creams or ointments rather than lotions for persistent dryness.
• Consider layering humectants under occlusive moisturizers for optimal hydration.

These combined approaches help to lock in moisture and prevent dryness effectively for dry skin.
