Cryotherapy for Skin Rejuvenation — Benefits and Risks

Last updated: 5 March 2026

Cryotherapy — the therapeutic application of extreme cold — has evolved far beyond its origins in sports medicine to become a valued tool in the aesthetic practitioner’s arsenal. From targeted cryoprobe treatments that address individual skin lesions to whole-body cryotherapy chambers that promise systemic anti-ageing benefits, cold-based therapies are experiencing a surge in popularity across UK aesthetic clinics.

How Cryotherapy Works on the Skin

The fundamental principle of aesthetic cryotherapy is controlled cold exposure, which triggers a cascade of beneficial physiological responses. When skin is exposed to extreme cold (typically between -110°C and -160°C for whole-body treatments, or -196°C for targeted liquid nitrogen applications), several key processes occur.

Vasoconstriction followed by vasodilation creates a “pumping” effect that increases blood flow to treated areas, delivering oxygen and nutrients whilst flushing away metabolic waste. The cold stimulus activates collagen production through a controlled inflammatory response, similar to the mechanism behind microneedling and laser treatments. Additionally, cryotherapy triggers the release of endorphins and anti-inflammatory cytokines that can improve overall skin health and appearance.

Types of Aesthetic Cryotherapy

Cryofacials involve directing a stream of vaporised liquid nitrogen over the face and neck for 10 to 15 minutes. The treatment tightens pores, reduces puffiness, increases circulation, and imparts an immediate “glow” that makes it popular before special events. A course of treatments can improve skin texture and firmness over time.

CryoSlimming and CryoToning use controlled cooling applied via specialised applicators to target specific body areas. CryoSlimming employs alternating warm and cold temperatures to trigger apoptosis (natural cell death) in fat cells, whilst CryoToning uses consistent cold temperatures to stimulate collagen production and improve skin texture without targeting fat.

Cryolipolysis (CoolSculpting) is the most evidence-based form of aesthetic cryotherapy. This FDA-cleared treatment uses controlled cooling to freeze and destroy subcutaneous fat cells, which are then naturally eliminated by the body over the following weeks. Multiple clinical trials have demonstrated an average 20-25% fat reduction in treated areas after a single session.

Targeted cryotherapy using liquid nitrogen or nitrous oxide cryoprobes is commonly used to treat benign skin lesions, age spots, solar keratoses, and skin tags. This precise application causes controlled destruction of unwanted tissue whilst preserving surrounding healthy skin.

Evidence-Based Benefits

The evidence base for cryotherapy varies significantly depending on the specific application. Cryolipolysis has the strongest clinical evidence, with multiple randomised controlled trials and systematic reviews confirming its efficacy and safety for non-invasive fat reduction.

For skin rejuvenation, emerging research suggests that regular cryotherapy sessions can improve skin elasticity, reduce the appearance of fine lines, and enhance overall skin quality. A study in the Journal of Clinical and Aesthetic Dermatology found that participants who underwent a series of cryofacial treatments showed measurable improvements in skin hydration and collagen density.

Whole-body cryotherapy has demonstrated benefits for inflammation reduction and recovery, though the specific dermatological benefits require further large-scale clinical investigation. The anti-inflammatory effects may indirectly benefit skin conditions such as eczema, psoriasis, and acne, though these applications remain the subject of ongoing research.

Risks and Side Effects

Cryotherapy is generally considered safe when performed by trained professionals using properly maintained equipment, but it is not without risks. Common side effects include temporary redness, numbness, and tingling in treated areas. These typically resolve within hours of treatment.

More significant risks include frostbite or cold burns if treatment parameters are incorrect or skin is exposed for too long. Paradoxical adipose hyperplasia — a rare complication of cryolipolysis where treated fat cells enlarge rather than shrink — occurs in approximately 0.005% of treatments but can be distressing and may require surgical correction.

Individuals with cold sensitivity conditions such as Raynaud’s disease, cold urticaria, or cryoglobulinaemia should avoid cryotherapy. Pregnant women, individuals with uncontrolled hypertension, and those with peripheral vascular disease are also typically excluded from treatment.

What to Expect During Treatment

A cryofacial session typically lasts 15 to 30 minutes. After cleansing, the practitioner directs cold vapour across the face in sweeping motions, maintaining a safe distance from the skin. Patients report a cool, tingling sensation that most find invigorating rather than uncomfortable.

Cryolipolysis sessions last 35 to 60 minutes per treatment area. The applicator suctions a fold of skin and fat, then cools it to the target temperature. Initial intense cold gives way to numbness within the first few minutes. After removal, the treated area is massaged to break up crystallised fat cells.

Choosing a Practitioner

As with all aesthetic treatments, the skill and experience of the practitioner are paramount. Patients should ensure their chosen clinic uses medical-grade equipment, maintains appropriate insurance, and employs practitioners with relevant training and qualifications. A thorough consultation should always precede treatment to assess suitability and discuss realistic expectations.
