Cryotherapy Applications in Modern Aesthetics

Last updated: 9 August 2026

Cryotherapy, the therapeutic application of extreme cold, has evolved significantly from its origins in general dermatology to become a versatile tool in modern aesthetic practice. From targeted cryolipolysis for fat reduction to whole-body cryotherapy for wellness benefits, cold-based treatments offer unique mechanisms of action that complement heat-based and injectable aesthetic procedures. We employ evidence-based cryotherapy applications as part of our comprehensive treatment portfolio.

The science of therapeutic cold

The biological response to controlled cold exposure involves a complex cascade of physiological events. When tissue temperature is reduced to specific thresholds, different cellular and molecular responses are triggered. Research published in the Journal of Clinical Investigation (Manstein et al., 2008), the pivotal paper that led to the development of cryolipolysis, demonstrated that adipocytes (fat cells) are more susceptible to cold-induced apoptosis than surrounding tissue, a phenomenon known as selective cryolysis.

At different temperature ranges, distinct biological effects occur:

• 10-15°C: Vasoconstriction followed by reactive vasodilation; anti-inflammatory effects
• 0-4°C: Reduced cellular metabolism, decreased nerve conduction velocity, analgesic effects
• -1 to -10°C: Selective adipocyte apoptosis (cryolipolysis range); crystallisation within fat cells
• Below -20°C: Tissue destruction (cryosurgery); used for benign lesion removal
• -110 to -160°C: Whole-body cryotherapy chamber temperatures; brief systemic cold exposure

Cryolipolysis: Non-surgical fat reduction

Cryolipolysis is the most established aesthetic cryotherapy application, with the most well-known commercial device being CoolSculpting. The treatment works by cooling subcutaneous fat to temperatures that trigger controlled apoptosis (programmed cell death) in adipocytes without damaging the overlying skin, muscles, or nerves.

How cryolipolysis works

During treatment, a vacuum applicator draws the target area of subcutaneous fat between two cooling panels, reducing tissue temperature to approximately -11°C for 35-60 minutes. Over the following 2-4 months, the body’s immune system gradually clears the damaged fat cells through natural inflammatory and phagocytic processes. The eliminated fat cells do not regenerate, making the results permanent provided the patient keeps a stable weight.

Cryotherapy for skin rejuvenation

Beyond fat reduction, cryotherapy principles are applied to skin rejuvenation through several modalities:

Cryo Facials

Localised cold therapy applied to the face using specialised devices or cooled gas streams produces vasoconstriction followed by reactive vasodilation. This vascular response increases blood flow and oxygen delivery to facial tissues, producing a temporary brightening and tightening effect. Whilst the evidence for long-term structural changes from cryo facials is limited, they are valued for their immediate refreshing effects and their ability to reduce post-treatment inflammation following other aesthetic procedures.

Cryosurgery for skin lesions

Liquid nitrogen cryotherapy remains one of the most widely used methods for removing benign skin lesions including seborrhoeic keratoses, skin tags, viral warts, and solar lentigines. The rapid freezing (-196°C) causes intracellular ice crystal formation, disrupting cell membranes and leading to lesion destruction. This well-established technique has been a staple of dermatological practice for over 50 years.

Whole-body cryotherapy

Whole-body cryotherapy (WBC) involves brief exposure (2-4 minutes) to extreme cold (-110 to -160°C) in a specialised chamber. Originally developed for inflammatory joint conditions, WBC has been adopted by the wellness and aesthetic industries for its proposed systemic benefits.

Published evidence for WBC includes a systematic review by Lombardi et al. (2017) in PLoS ONE which found that WBC produces measurable anti-inflammatory effects (reduced IL-6 and TNF-alpha levels), increases noradrenaline release (potentially improving mood and energy), and may temporarily increase metabolic rate. However, the authors noted that evidence for long-term aesthetic benefits such as skin improvement and fat loss remains limited, and more high-quality randomised trials are needed.

Safety Considerations

Cryotherapy treatments have specific contraindications that must be assessed during consultation:

• Cryoglobulinaemia and cold agglutinin disease
• Raynaud’s phenomenon (for the target treatment area)
• Paroxysmal cold haemoglobinuria
• Cold urticaria
• Peripheral neuropathy in the treatment area
• Poor circulation or peripheral vascular disease

Cryolipolysis carries a rare but documented risk of paradoxical adipose hyperplasia (PAH), a condition where the treated area develops increased fat volume rather than reduced volume. This risk is discussed during all consultations for cryolipolysis treatment.

Frequently asked questions

How much fat can cryolipolysis remove?

Cryolipolysis is designed for targeted fat reduction rather than weight loss, it is most effective for stubborn pockets of fat that resist diet and exercise, such as love handles, lower abdomen, and double chin.

Is cryolipolysis painful?

Most patients experience intense cold and a pulling sensation during the first 5-10 minutes of treatment, which subsides as the area becomes numb. After the applicator is removed, the treated area is massaged, which can cause temporary discomfort. Post-treatment, patients may experience numbness, tingling, redness, or mild bruising for 1-2 weeks.

How long does it take to see results from cryolipolysis?

Results develop gradually as the body clears the damaged fat cells. Most patients begin to notice changes at 4-6 weeks, with optimal results visible at 2-3 months post-treatment. Some patients continue to see improvement for up to 6 months.

Is whole-body cryotherapy scientifically proven?

Whole-body cryotherapy has documented short-term effects including reduced inflammation markers, increased noradrenaline, and temporary metabolic boost. However, the evidence for long-term aesthetic benefits is still developing. It is best viewed as a complementary wellness treatment rather than a primary aesthetic intervention.
