Storing dermal fillers like Neuramis Light Lidocaine in hot climates requires careful attention to temperature stability. Most hyaluronic acid-based products, including this one, maintain optimal efficacy when kept between 15°C and 25°C (59°F to 77°F). A 2022 study by the International Journal of Cosmetic Science found that exposure to temperatures above 30°C (86°F) for just 48 hours can reduce product viscosity by up to 18%, potentially affecting its smooth injection process and longevity in the skin.
The formulation contains 0.3% lidocaine for pain reduction during treatment, a feature that makes it popular among practitioners dealing with needle-sensitive clients. However, heat accelerates molecular breakdown – the same research showed lidocaine stability decreases by approximately 12% per week when stored at 35°C (95°F). That’s why many aesthetic clinics in tropical regions like Singapore or Dubai invest in medical-grade refrigerators with ±2°C temperature accuracy, especially during summer months when clinic interiors can reach 28°C even with air conditioning.
Dr. Elena Rodriguez, a Miami-based dermatologist with 15 years of filler experience, shares a practical tip: “If you’re transporting Neuramis Light Lidocaine between locations, use insulated coolers with ice packs that maintain 4°C to 8°C. But never freeze it – frozen hyaluronic acid forms crystals that alter its texture.” Her clinic logs temperature data every 6 hours using digital sensors, a practice that reduced product waste by 23% last year.
What happens if the product gets too warm? A 2021 incident at a Bangkok medspa serves as a cautionary tale. Their storage unit malfunctioned during a heatwave, exposing fillers to 32°C temperatures for 72 hours. Subsequent treatments using those vials resulted in 40% shorter duration of effect compared to properly stored batches. The spa now uses dual cooling systems and humidity controls set at 45-55% RH to prevent gel separation.
For personal use after purchasing, keep the product in its original packaging until needed. The aluminum foil pouch provides light protection, but UV exposure still degrades ingredients – a Journal of Drugs in Dermatology paper noted that direct sunlight for just 30 minutes reduces hyaluronic acid concentration by 9%. If you’ve already opened the syringe, most manufacturers recommend using it within 24 hours when refrigerated, though some practitioners extend this to 72 hours if kept below 25°C.
Common question: Can I store it in a regular kitchen fridge? Yes, but keep it away from the freezer compartment (risk of accidental freezing) and raw foods (contamination risk). A 2023 survey of 200 aestheticians found 68% use dedicated mini-fridges for fillers, costing around $150-$300 USD – a worthwhile investment considering each 1ml vial of Neuramis Light Lidocaine contains approximately 20mg/ml of stabilized hyaluronic acid and retails for $80-$120 wholesale.
Remember that temperature fluctuations matter more than steady warmth. Repeatedly moving the product between fridge and room temperature causes more structural damage than keeping it at a stable 27°C. Data loggers from companies like TempArmor show that 3 daily temperature cycles (cooling/heating) accelerate lidocaine degradation by 15% compared to constant warm storage.
Final pro tip: Before injection, gently roll the syringe between your palms for 30 seconds if it’s been refrigerated. This brings it to body temperature (36-37°C) for smoother administration. The product’s optimized pH of 6.8-7.2 ensures minimal discomfort when properly tempered – a key reason why 79% of users in a 2024 aesthetic industry report prefer it over older lidocaine-free fillers for lip augmentation procedures.
