Aqurea HF (Hand & Foot) Cream is a high-potency keratolytic and emollient formulation designed for the management of hyperkeratotic skin conditions. It is a specialized dermatological treatment used to address extreme dryness, thickening of the skin (tylosis), and fissuring, primarily on the palms and soles. The “HF” designation signifies its optimization for the thicker epidermal layers of the hands and feet. By utilizing a high concentration of urea in a stable vehicle, it facilitates the breakdown of hardened keratin while restoring the skin’s natural moisture-binding capacity.
Pharmacological Composition (Key Ingredients)
Urea (40%): At this high concentration, urea acts as a potent keratolytic. It softens the “intercellular cement” of the stratum corneum, allowing dead, thickened skin to shed. It also serves as a powerful humectant, drawing water into the deeper layers of the skin.
Lactic Acid: An Alpha Hydroxy Acid (AHA) that assists in exfoliation and helps regulate the skin’s pH, further softening calloused tissue.
Cream Base (Emollients): A rich blend of lipids and occlusives that forms a protective barrier to prevent Transepidermal Water Loss (TEWL) and shield cracked skin from environmental irritants.
Clinical Benefits
Hyperkeratosis Management: Effectively reduces the thickness of calluses and hardened skin patches on the heels and palms.
Fissure Repair: Deeply hydrates dry, cracked skin, promoting the healing of painful fissures by restoring elasticity to the epidermal tissue.
Intense Rehydration: Increases the water-holding capacity of the skin, providing relief from chronic xerosis (pathological dryness).
Smoothing Action: Refines skin texture by facilitating the desquamation of rough, scaly patches.
Barrier Restoration: Helps rebuild the skin’s protective lipid layer, preventing future moisture loss and protecting against friction.
Dermatological Application (How to Use)
For maximum penetration into thickened skin, the following clinical protocol is recommended:
Preparation: Soak the affected hands or feet in warm water for 5–10 minutes to soften the keratin. Pat the skin dry, leaving it slightly damp.
Application: Apply a generous amount of Aqurea HF cream to the thickened or cracked areas.
Massage: Rub the cream thoroughly into the skin until it is completely absorbed.
Occlusion (Optional for severe cases): For intense treatment, apply the cream at bedtime and cover the area with cotton socks or gloves to enhance urea penetration.
Frequency: Apply twice daily or as directed by a healthcare professional.
Hand Hygiene: Wash hands after application if the treatment was intended only for the feet, as high-strength urea can cause mild peeling on thinner skin.
Safety and Storage
Precautions: For external use only. Avoid application on highly sensitive areas, face, or mucous membranes.
Adverse Reactions: A transient stinging or burning sensation may occur, especially if applied to open fissures or broken skin. If irritation persists, discontinue use.
Contraindications: Not recommended for use on acutely inflamed or oozing skin.
Storage: Store in a cool, dry place below 25°C. Keep the tube tightly closed to prevent the cream from drying out.
