Clinical featuresThis section has been translated automatically.
Dermatitis occurring after exposure to the sun, initially acute to sub-acute, sharply defined, itchy or burning dermatitis, later streaky hyperpigmentation at the contact points. S.a.

TherapyThis section has been translated automatically.
Avoid the agent, otherwise blank local therapy with non-perfumed external care products (e.g. Ungt. emulsif. aq.). Short-term glucocorticoid-containing external agents, e.g. betamethasone valerate (Betnesol-V Lotio, R030 ). In case of persistent post-inflammatory hyperpigmentation chemical peeling may be necessary.
