What is dermatology?
Dermatology is a branch of medicine dedicated to the diagnosis, treatment, and prevention of conditions affecting the skin, hair, nails, and mucous membranes. It encompasses both medical and cosmetic concerns. Cryotherapy, meaning “cold therapy,” involves the application of extremely low temperatures to treat various skin conditions. It is commonly used to remove surface lesions by freezing them with cryogenic substances. Liquid nitrogen (LN₂) is the most widely used cryogen in dermatological cryotherapy due to its safety and effectiveness.

Liquid nitrogen in dermatology
Liquid nitrogen, with a boiling point of -196°C, is a colourless, odourless cryogen that leaves no residue. Its ability to rapidly freeze tissue makes it ideal for use in cosmetic and medical dermatology. When applied to abnormal tissue, it forms ice crystals inside cells, disrupts cellular structures, denatures proteins, and restricts blood flow, leading to the controlled destruction of targeted tissue.
Common applications include:
- Benign skin lesions
- Warts
- Actinic keratoses
- Low-grade skin cancers
Liquid nitrogen cryotherapy is fast, minimally invasive, and highly effective, making it a go-to treatment in outpatient dermatological care.

Why choose liquid nitrogen generators?
Liquid nitrogen generators offer several advantages over traditional methods of liquid nitrogen supply:
- Reliable Supply: Ensures a continuous and uninterrupted supply of liquid nitrogen.
- Reduced Maintenance: Requires minimal maintenance, saving time and resources.
- Improved Safety: Eliminates the risks associated with handling and transporting large quantities of liquid nitrogen.
- Cost-Effective: Offers long-term cost savings by reducing reliance on external suppliers.
- Environmental Benefits: Reduces carbon emissions and promotes sustainable practices.
By utilizing liquid nitrogen generators, pharmaceutical companies can optimize their operations, improve efficiency, and enhance the quality of their products.

The benefits of on-site generation for dermatology
On-site liquid nitrogen generation eliminates the need for purchasing, storing, and transporting traditional bulk supplies, avoiding boil-off losses and logistical challenges. With continuous, on-demand production, practices are no longer vulnerable to supply chain disruptions.
Liquid nitrogen generators from Noblegen are energy-efficient, low-noise, and compact, making them an ideal solution for outpatient clinics, dermatology offices, and mobile medical units. They offer a more convenient, cost-effective, and reliable approach to cryotherapy.
