A Guide to Occlusives for Dehydrated Skin

Dehydration in the skin is defined by a lack of water content rather than oil. When the outer layer of the skin is compromised, moisture evaporates from the surface, a process known as transepidermal water loss. Occlusives are cosmetic ingredients that sit on top of the skin to block this evaporation.

Applying an occlusive is the final step in a routine. It seals in humectants and emollients, ensuring the moisture already present in the skin remains there. This guide outlines how to select and apply an occlusive layer effectively.

1. Cleanse the skin. Begin with a mild cleanser to remove surface debris. Avoid harsh soaps that strip natural oils, as this increases the likelihood of water loss. Pat the skin dry with a clean, soft towel.
2. Apply a humectant. Apply a water-based serum or toner containing ingredients like glycerin or hyaluronic acid while the skin is still slightly damp. These ingredients draw moisture toward the skin. Allow the product to absorb for approximately sixty seconds.
3. Seal with an occlusive. Dispense a pea-sized amount of an occlusive-rich cream or balm into your palms. Gently press the product onto the face in a thin, even layer. Focus on areas prone to dryness, such as the cheeks or around the nose.
4. Allow for absorption. Wait several minutes for the product to settle. Occlusives are often dense, so they require more time to distribute across the skin. Resist the urge to rub or manipulate the skin during this time.
5. Cleanse the next morning. Because occlusives create a persistent film, they should be removed in the morning. Use a gentle cleanser to clear the residue from the night before. This prepares the skin for your daytime routine.

Occlusives do not add moisture; they keep existing moisture from leaving.
