Cala-Duo Lotion provides an established, clinically unified topical antipruritic and skin-protective therapy carefully developed for the rapid management, symptom containment, and stabilization of acute dermal itching and inflammation. When the skin barrier is stressed by solar radiation, heavy sweating, or insect saliva deposits, localized mast cells flood the surrounding tissue with histamine. This biochemical surge triggers intense sensory nerve flaring (itching), capillary dilation (redness), and hot, painful swelling. This advanced formulation delivers a protective astringent barrier combined with a localized histamine blocker within a standard 120 ml liquid suspension layout, restoring immediate skin comfort safely over a regular home care routine.
The synchronized formulation operates dynamically across multiple dermatological fronts:
-
Topical Antihistamine Action (Diphenhydramine HCl): Functions as a potent inverse agonist that blocks localized $H_1$ histamine receptors along the nerve endings of the skin. By systematically shutting down histamine binding paths, it intercepts the itch transmission signal before it triggers scratching reflexes, stopping the itch-scratch cycle around the clock.
-
Astringent Guard & Evaporative Cooling (Calamine & Camphor): Calamine forms a physical zinc-oxide-based protective shield over damaged skin layers, absorbing oozing fluids from raw rashes and exerting a natural protective tightening action. Concurrently, Camphor provides a gentle, localized anesthetic and counter-irritant property—evaporating rapidly from the skin surface to generate a refreshing cooling wave that instantly masks burning pain.

Directions for Use
-
For External Topical Use Only. Strictly do not ingest orally or apply inside the mouth, eyes, or genital tracts.
-
Shake the bottle thoroughly immediately before every single application. Calamine is a heavy mineral suspension that naturally settles at the bottom; shaking guarantees a uniform, medication-rich blend.
-
Standard Application Layout: Cleanse the affected skin area gently with mild soap and cool water, then pat it completely dry. Pour a small pool of Cala-Duo Lotion onto a sterile cotton pad or your clean fingertips and spread it smoothly over the irritated skin patches.
-
Allow the pink lotion to air-dry completely into a fine, protective mineral crust. Do not wash or rub it off prematurely.
-
Reapply 3 to 4 times daily, or precisely as directed by your dermatologist to maintain continuous skin containment.
Safety & Precautions
-
Strictly avoid contact with your eyes, eyelids, nose, or inner lip linings. In case of accidental contact, flush the mucous membranes immediately with large streams of cool, plain water for several minutes.
-
Do not apply over raw, open wounds, deep skin punctures, severe weeping infections, or raw blistered skin coverings, as systemic absorption of diphenhydramine through broken flesh should be restricted.
-
Do not apply wrapping bandages or tight plastic dressings over the freshly treated skin area without explicit medical guidance.
-
Discontinue use instantly and seek specialist advice if your skin irritation worsens noticeably, or if a sudden, unprovoked burning skin rash develops.
-
Keep out of reach of children.
Storage
-
Store in a cool, dry place below 30°C. Do not freeze.
-
Protect the bottle from direct sunlight exposure, high shelf heat channels, and excessive humidity arrays.
-
Always screw the dark metal cap back on perfectly tight immediately after use to prevent the liquid base from drying out or drawing in floating room dust.
