For lichen simplex chronicus with pruritus, which statement about occlusive dressings is correct?

• A. Apply ointment before the dressing.
• B. The dressing should be applied to damp skin.
• C. Plastic wrap should not be used.
• D. Change the dressing twice daily.

Answer: (A)

Occlusion increases skin hydration and helps topical medications penetrate better, which is especially useful in lichen simplex chronicus to reduce itching and break the itch-scratch cycle. The best approach is to apply the ointment directly to the lesion first, then cover it with the occlusive dressing. This sequence ensures the medication is present on the skin and can be absorbed under the occlusion, maximizing effectiveness. Applying the dressing to damp skin can lead to maceration and washes away the medication, reducing its impact. The use of plastic wrap as an occlusive cover can be appropriate in some cases, but the critical point is that the ointment should be applied before occlusion to maintain proper delivery. Dressing changes are usually less frequent to maintain continuous absorption, rather than changing twice daily.
