Ichthyosis Vulgaris: Next-Line Management After Topical Keratolytic Therapy Fails to Clear Skin
In patients with ichthyosis vulgaris, intensive topical keratolytic treatment is the established starting point. When that approach does not achieve the expected skin-clearance goals, a structured next-line protocol is indicated.
Why the Previous Step Was Insufficient
First-line treatment — regular balneotherapy with keratolytic bath additives, mechanical keratolysis, and daily topical agents such as glycerol, urea, sodium chloride, or lactic acid — targets removal of hyperkeratosis and scales, smoother skin, and healing of rhagades. When these goals remain unmet, the next protocol step is warranted.
Next-Line Approach — Partial Overview
The next step involves systemic therapy with acitretin — the only agent with regulatory approval for systemic treatment of ichthyoses — continued alongside intensive topical care, with restoration of the ability to perspire as a key clinical goal. The complete regimen and dosing strategy are available via the link below.

- Acitretin is the only agent approved for the systemic treatment of ichthyoses.
- While the acitretin dose can initially be gradually increased, the long-term goal is to reach a maintenance dose that is as low as possible.
- The improved ability to perspire can be a key reason in favor of using acitretin.
