Removing Skin Tags, Warts and Freckles — Modern Techniques at a Dermatology Clinic

Skin tags, warts and freckles are examples of skin lesions that can affect confidence. Many people want them removed safely, without leaving scars. Dermatology clinics today use several modern techniques to achieve the best possible results. In this article, a dermatology specialist doctor explains what each lesion is, the removal techniques, safety, and aftercare.

What are skin tags, warts and freckles?

• Skin tag: A small, soft growth, usually found on the neck, armpits or under the breasts. It is a non-serious lesion.

• Wart: Caused by infection with the HPV virus and can be spread to others.

• Freckle/age spot: A dark spot on the skin caused by uneven accumulation of pigment, often related to sun exposure.

Removal methods used at the clinic

The dermatologist chooses a technique to suit the type of lesion, including:

• For skin tags: High-frequency electrocautery and carbon dioxide laser (CO2 Laser) are suitable for skin tags.

• For warts: Cautery, freezing (cryotherapy) or injections are suitable for warts.

• For freckles: Nd:YAG laser or IPL helps reduce the pigment of freckles.

• Additional technique: Radiofrequency is another option for some lesions.

The doctor always assesses the lesion first to choose the most appropriate and safest method for each patient.

Safety and telling lesions apart

Before removing a skin tag, wart or freckle, it is important to have a dermatologist examine it first, to rule out abnormal lesions such as skin cancer. A lesion that is uncertain should have a biopsy for confirmation. Removing a lesion yourself without an examination may cause a serious lesion to go undiagnosed.

Aftercare

• Wound care: Keep the wound clean as advised by your doctor.

• Sun protection: Avoid sunlight for the first 2 weeks and apply sunscreen regularly, especially after freckle removal, to prevent them from coming back.

• Medication and follow-up: Apply creams as your doctor recommends so the wound can heal fully, and attend follow-up appointments as scheduled.

Frequently asked questions

Is skin tag removal painful? Removal with laser or radiofrequency can use local anesthesia to reduce pain, so you feel more comfortable during the procedure.

Will they come back after removal? Skin tags may return if they are in an area with frequent friction, but the chance can be reduced with proper care. Freckles may reappear if you do not protect your skin from the sun.

Do I need a doctor's examination before removal? Very much so, because some lesions can look similar to skin cancer. Having a doctor examine you first helps tell them apart and plan treatment safely.

What is the difference between a wart and a skin tag? A wart is caused by the HPV virus and is contagious, while a skin tag is a non-serious growth that is not contagious. The removal method therefore differs depending on the type of lesion.
