Seborrheic Keratosis at a glance
Our results speak for themselves
Also known as seborrheic keratosis /warts/age warts/age barnacles, these are benign lesions that increase in size & number with age. They are often pigmented & comprise overgrowths of normal skin cells.
Seborrheic warts commonly occur on the face, neck, trunk & lower limbs.
By definition, no, however in rare cases, seborrheic warts can contain foci of superficial skin cancers known as IEC or intraepithelial carcinoma.
The best treatments are most often the simplest, namely a curette. Seborrheic keratosis in cosmetically sensitive areas such as the face, we use ablative lasers.
In extensive areas we use numbing gel prior to the procedure. If only one or two areas are involved, local anaesthetic is used.
Ablative CO2 & erbium lasers give the best results. It takes between 20-60 seconds to treat each wart.
The treated area heals in 4-7 days. You may have some redness over the area for 4-6 weeks. Scarring using this technique is very rare, less than 1% of cases.

Compounded keratolytics can prevent or reduce recurrence but will not treat established warts.
Seborrhoeic warts increase with age. We employ treatments such as lasers, electrosurgery & minimally invasive procedures to effectively remove warts with minimal downtime & no scarring.
Nitrogen is a good treatment if you are not worried about cosmetic outcomes. They should be used in caution on the face. Aggressive treatments will result in hyperpigmentation or a white scar.
Nitrogen to the lower limbs can result in ulceration & poor wound healing.

Dermatologists can prescribe topical retinoids & exfoliating acids including salicylic, lactic, & glycolic acids.
Creams only reduce recurrence. Inflamed seborrheic warts can be treated with CS creams.
With caution & precision. Warts including age spots can be tricky in darker skin types as post inflammatory hyperpigmentation can result. On this basis we use special lasers known as picolasers- namely Picosure Pro & Picoway.
Patients will require between 2-4 sessions for optimal results.
Some warts can be treated with home liquid nitrogen kits. Another option is with Wart Kill or higher strength salicylic acid preparations. Obviously don’t spill any on normal skin.
DIY treatments are not recommended if you have warts on the face & or have a darker skin color.
