Possible immediate side effects:
Pain – discomfort at the time and for a variable time following the procedure.
Swelling and redness – this is a normal and usually settles in a few days.
Cryotherapy close to the eyes may induce prominent puffiness of the lower
eyelids which settles within days.
Blistering – this is common and sometimes the blisters are filled with blood.
This is harmless. If painful, a blister may be burst with a clean needle. We do
not recommend this as it can introduce infection. If a blister breaks, wipe the
area with antiseptic.
Scabbing – facial scabbing lasts around 7 days. Hands often blister, then
scab, healing in 3 weeks. The legs may take 6-12 weeks to heal.
Infection – (uncommon) increased pain, redness and discharge. Please seek
prompt medical treatment from the practice as you may need antibiotics.
Possible long term side effects:
Scarring – you may be left with a pale mark or a flat white scar.
Hypertrophic/Keloid scarring – very rarely a raised firm scar can form.
Numbness - if a superficial nerve is frozen, it may result in numbness of the
area of skin supplied by that nerve. Normal feeling may return within months.
Recurrence – treatment may fail, or the growth may recur. You may need a repeat
treatment or a different treatment. It is important to return to see your doctor if the
skin lesion returns and very important if it is growing - this may be a sign of skin cancer.
