Cryotherapy in Aesthetics — Benefits and Limitations

Last updated: 5 March 2026

Cryotherapy — the therapeutic application of extreme cold — has gained significant traction in the aesthetics industry, with proponents claiming benefits ranging from skin tightening and fat reduction to improved skin tone and accelerated recovery. But how much of this is supported by clinical evidence, and where does marketing enthusiasm outpace scientific reality? This comprehensive analysis separates fact from fiction in aesthetic cryotherapy.

Types of Cryotherapy in Aesthetic Practice

Aesthetic cryotherapy encompasses several distinct modalities, each utilising cold temperatures in different ways and for different purposes. Understanding these distinctions is crucial for evaluating their respective merits and limitations.

Localised Cryotherapy (Targeted Cooling)

Localised cryotherapy applies controlled cooling to specific body areas using handheld devices or applicators. This category includes both superficial skin treatments and deeper tissue cooling. Temperatures typically range from -10°C to -30°C, applied for periods of 5-15 minutes. The controlled nature of localised application allows for more precise targeting and more predictable outcomes compared to whole-body approaches.

Cryolipolysis (Fat Freezing)

Cryolipolysis, commercialised primarily as CoolSculpting, represents the most evidence-based application of cryotherapy in aesthetics. Based on the observation that fat cells are more susceptible to cold-induced damage than surrounding tissues, cryolipolysis selectively destroys subcutaneous fat cells by cooling them to temperatures that trigger apoptosis (programmed cell death) without harming the overlying skin. Treatments typically cool tissue to approximately -11°C for 35-75 minutes.

Whole-Body Cryotherapy (WBC)

Whole-body cryotherapy involves brief exposure (2-4 minutes) to extremely cold temperatures (-110°C to -160°C) in a specialised chamber or cabin. Originally developed for the management of inflammatory conditions such as rheumatoid arthritis, WBC has been widely adopted in sports recovery and wellness settings. Its aesthetic applications remain the most contested area of cryotherapy.

Cryo Facials

Cryo facials use controlled streams of vaporised liquid nitrogen or cold air directed at the face, typically at temperatures of -30°C to -70°C for 10-15 minutes. These treatments aim to constrict blood vessels (reducing puffiness and redness), stimulate collagen production, and create an immediate tightening effect. They have become popular as “lunchtime treatments” due to their quick application and zero downtime.

Evidence-Based Benefits: What the Research Shows

Claimed Benefit	Evidence Level	Assessment
Fat reduction (cryolipolysis)	Strong (multiple RCTs)	Well-established; 20-25% fat reduction per area per treatment
Post-procedure inflammation	Moderate	Cold application reduces swelling; standard medical practice
Temporary skin tightening	Low-moderate	Temporary vasoconstriction effect; minimal lasting change
Collagen stimulation	Low	Limited human evidence; animal studies suggestive
Cellulite reduction	Very low	Insufficient evidence for meaningful improvement
Anti-ageing/wrinkle reduction	Very low	No robust clinical evidence for long-term benefit
Weight loss	Minimal	Caloric burn from WBC is negligible (approx. 80-100 kcal)

Cryolipolysis: The Gold Standard of Aesthetic Cryotherapy

Of all cryotherapy modalities, cryolipolysis has the strongest evidence base. Since its FDA clearance in 2010, numerous randomised controlled trials have demonstrated consistent fat reduction of approximately 20-25% in treated areas after a single session. The treatment works through a well-understood mechanism: controlled cooling triggers adipocyte apoptosis, followed by gradual clearance of dead fat cells through the body’s lymphatic system over 2-3 months.

Key clinical findings include results that develop gradually over 8-12 weeks as dead fat cells are metabolised, that most patients require 1-2 treatments per area for optimal results, and that results are permanent (destroyed fat cells do not regenerate), though remaining cells can enlarge with weight gain. UK pricing typically ranges from £600-£1,200 per area per session.

However, cryolipolysis is not without limitations. It is designed for spot reduction of stubborn fat deposits, not as a weight loss solution. It works best for patients within a healthy weight range who have localised fat deposits resistant to diet and exercise. Additionally, a rare but significant complication — paradoxical adipose hyperplasia (PAH), where the treated area actually increases in size — occurs in approximately 0.005-0.39% of treatments.

Cryo Facials: Temporary Glow or Lasting Improvement?

Cryo facials have become enormously popular, fuelled by celebrity endorsements and social media visibility. The immediate effects — reduced puffiness, a tighter appearance, a visible glow — are real and can be explained by basic physiology: cold exposure causes vasoconstriction (narrowing of blood vessels), which reduces fluid accumulation and creates a temporary tightening effect. When the cold is removed, reactive vasodilation brings increased blood flow to the area, creating the characteristic “glow.”

The critical question is whether these effects translate into lasting improvements in skin quality. The honest answer, based on current evidence, is that they largely do not. While regular cryo facials may provide cumulative benefits through repeated stimulation of blood flow and mild inflammatory responses, the evidence for meaningful collagen stimulation or long-term anti-ageing effects is limited. For patients seeking evidence-based skin rejuvenation, treatments such as polynucleotides, retinoids, or energy-based devices offer better-documented long-term outcomes.

Whole-Body Cryotherapy: Aesthetic Claims Under Scrutiny

Whole-body cryotherapy (WBC) has been marketed with numerous aesthetic claims, including skin tightening, improved skin tone, cellulite reduction, collagen production, and even weight loss. However, the evidence for these specific claims is limited.

The Cochrane Collaboration — the gold standard for systematic reviews of healthcare interventions — concluded in a 2015 review that there was insufficient evidence to determine whether WBC provided benefits beyond conventional cold therapy for any condition. While newer studies have shown some promise for sports recovery and inflammatory conditions, the aesthetic-specific evidence remains thin.

The weight loss claim is particularly misleading. While the body does expend energy to maintain core temperature during WBC, the caloric expenditure is modest — approximately 80-100 calories per session, equivalent to a brisk 15-minute walk. Marketing claims of 500-800 calories per session have been widely debunked.

Safety Considerations and Risks

Cryotherapy is generally safe when administered by trained professionals using appropriate equipment. However, risks include frostbite or cold burns from improper application or equipment malfunction, nerve damage from prolonged cold exposure, paradoxical adipose hyperplasia (PAH) from cryolipolysis, contraindications for patients with Raynaud’s disease, cold urticaria, or cryoglobulinaemia, and cardiovascular risks during whole-body cryotherapy for patients with uncontrolled hypertension.

In the UK, cryotherapy is not currently regulated under the Health and Care Act 2022 provisions for non-surgical cosmetic procedures, though cryolipolysis devices require CE/UKCA marking. Patients should ensure their provider uses properly maintained, certified equipment and has appropriate training and insurance.

Who Should Consider Aesthetic Cryotherapy?

The suitability of cryotherapy depends entirely on which modality and what goals are being considered:

• Cryolipolysis is suitable for: Patients at or near their ideal weight with localised fat deposits (love handles, abdominal fat, double chin, bra fat) that resist diet and exercise
• Cryo facials may be enjoyable for: Patients seeking a quick, refreshing treatment before an event; those who enjoy the sensation and temporary brightening effect; patients using it as a complement to evidence-based treatments
• Whole-body cryotherapy may benefit: Athletes seeking recovery; patients with inflammatory conditions (under medical supervision); those who enjoy the general wellness and endorphin-releasing effects

Cost Comparison: UK Pricing

Cryotherapy costs vary significantly depending on the modality. Cryo facials typically cost £50-£150 per session, with packages of 6-10 sessions often available. Cryolipolysis ranges from £600-£1,200 per treatment area. Whole-body cryotherapy sessions range from £40-£80 per session, with monthly memberships available at some facilities for £150-£300. When evaluating cost-effectiveness, it is important to consider the evidence base for each modality and whether the investment is likely to deliver meaningful, lasting results.
