Treatment near the eye may result in a puffy eyelid. The treated area is likely to blister within a few hours and a scab usually forms. Usually no special attention is needed during the healing phase. Keep the treated area clean and dry. Otherwise, when the blister dries to a scab, apply petroleum jelly and avoid picking at it.
Secondary infection is uncommon.
When it occurs it may cause increased pain, swelling, discharge and redness around the treated area. Antibiotics may be necessary. Cryotherapy may result in a white mark or a scar, particularly if a deeper freeze is required eg. for a cancerous lesion. The treatment may prove unsuccessful, necessitating further cryotherapy or surgery.
