Residents in Westminster and Pimlico looking to deal with minor skin blemishes without a lengthy referral process now have a nearby option: a Mayfair aesthetic clinic is offering CryoPen treatment, a precision cryotherapy technique that removes benign skin lesions in a single, same-day appointment.
CryoPen uses controlled liquid nitrous oxide to freeze targeted skin tissue with a high degree of precision, treating common lesions such as skin tags, warts, verrucas, milia, and sun or age spots. The device is FDA-cleared and CE-marked, and is increasingly used by clinics across the UK as an alternative to older freezing methods.
A common complaint, often left untreated
Skin tags, milia and age spots are among the most frequent reasons people visit a GP or dermatology clinic, yet many are left untreated for years simply because they're considered a low priority for the NHS, or because people assume removal means a referral, a wait, and a scar. That perception is often out of date. For lesions that are cosmetic rather than medically concerning, private clinics can typically assess and treat in the same visit.
How it compares to older methods
Cryotherapy itself isn't new. GPs have used liquid nitrogen to freeze warts and skin tags for decades, usually with a hand-held spray canister that treats a wider area than intended. What's changed with CryoPen is the precision. Its finer, pen-style application targets the lesion itself far more accurately, which typically means less discomfort during treatment and a lower chance of affecting the surrounding healthy skin, an issue that has historically been the biggest complaint about older freezing techniques.
"It's a treatment people often assume needs a GP referral and a long wait," says Dr Hasaneen Al Janabi, who provides CryoPen treatment in Mayfair. "In most cases we can assess and treat a lesion in the same appointment, which matters to people who've been living with something minor but visible for months or years. It's often something people have simply learned to live with, rather than something they've actively chosen to keep."
What treatment involves
Sessions are brief, typically 5 to 15 minutes per lesion depending on size and number. Patients may feel a brief stinging or freezing sensation as the device is applied, but the procedure requires no cutting, stitches or anaesthetic. Treated areas scab lightly and fall away naturally within one to two weeks, generally without scarring, revealing smooth skin underneath. Downtime is minimal, and most patients resume normal activities, including work, immediately afterwards.
As with any skin lesion, the clinic advises that anything new, changing, or of uncertain origin should be properly assessed before treatment, to rule out anything requiring dermatology referral rather than cosmetic removal.
