Moles, Warts & Skin Tags Scars

Over the past decade, advances in laser technology have allowed dermatologists to improve the appearance of scars and wrinkles and to remove benign skin growths using both ablative and nonablative lasers

Indications of co2 laser

Actinic and seborrheic keratosis, warts, moles, skin tags, epidermal and dermal nevi , xanthelasma Other conditions that have been shown to respond favorably to carbon dioxide laser resurfacing include rhinophyma  severe cutaneous photodamage , syringomas,  actinic cheilitis  angiofibroma scar treatment keloid neurofibroma  and diffuse actinic keratosis

Patient selection, counseling and informed consent

As with any cosmetic procedure, proper patient selection is essential.

  • History of previous laser resurfacing, dermabrasion or deep phenol peel should be noted,because these procedures could potentially delay the wound healing response due to the presence of fibrosis When applicable, patients should be discouraged from smoking before and after surgery to reduce the risk of delayed or impaired wound healing.
  • Skin to be treated should be thoroughly examined-scarring, dyschromia, rhytid formation, and skin type should be noted carefully. For patients desiring periorbital laser treatment the eyes should be carefully examined for scleral show, lid lag, and ectropion.
  • Most importantly, patients should have realistic expectations and sound reasons for deciding to undergo the cosmetic laser surgical procedure. Other cosmetic treatment options should be reviewed too so that the patient may make an informed decision.

The patient should understand that there is a postoperative healing phase with erythema and crusting that lasts for 1-2 weeks. The need to avoid sunlight during postoperative healing should be emphasized. It is worthwhile to include explicit instructions to the effect in the consent form .

While CO  2  laser resurfacing is usually a one-time procedure, many patients may need repeat treatments and if the physician thinks that a second session may be needed,


  • Absolute contraindications include, active cutaneous bacterial or viral infection in the area to be treated, and ectropion (for infraorbital resurfacing).
  • Relative contraindications include patient history of keloid formation or hypertrophic scarring, on going ultraviolet exposure, prior radiation therapy to treatment area, and collagen vascular disease.
  • Caution should be taken with patients who smoke or who have a history of previous laser resurfacing, phenol chemical peel, dermabrasion, and/or transcutaneous lower blepharoplasty.


For small lesions, EMLA cream applied under occlusion for 30-60 minutes is adequate. For localized areas, local infiltration with 1% lidocaine and epinephrine is usually sufficient to produce adequate anesthesia. For larger areas, such as full-face resurfacing, nerve blocks ( e.g ., supraorbital, supratrochlear, infraorbital, mental) may be needed along with local infiltration.

Postoperative care and complications

Carbon dioxide laser resurfacing imparts a thermal injury to denuded skin. Nearly all patients encounter minor side effects ranging from postoperative pain and edema to pruritus and tightness.

Postoperative edema (swelling) may occur, which usually subsides with cold compresses and nonsteroidal anti inflammatory drugs.

  • A mild serous (watery) discharge is seen, which subsides spontaneously by the 2nd or 3rd postop day.
  • Avoidance of undue sun exposure and use of broad spectrum sunscreens is mandatory.

Moles/Warts/skin tags scars FAQ’s

What do I expect after grafting?

Recovery and healing time after dermabrasion (removal of moles, Warts & skin tags scars ) depends on the size and depth of the area treated. Patients must:

  • Cleanse the treated area several times daily to prevent infection.
  • Change ointments and dressings to promote healing.
  • Avoid exposure to the sun.

Skin regrowth occurs within five to eight days. New skin is pink or red in appearance, fading to normal skin tones in six to 12 weeks. Pain and swelling is generally minimal after the procedure, though pain killers and steroids are prescribed in some cases. Your ASDS doctor may schedule follow-up visits to monitor your progress.

How to remove them?

The most common ways to remove them are:

Cryotherapy – Use liquid nitrogen to freeze them.
Electrocautery or Lasers – Any of the 2 methods are used to remove the moles & warts.

What are moles & skin tags ?

Moles are small grafts of skin that can develop on any part of the body over time. Skin tags are minute, soft pieces of skin that stick out on a slender stem. They appear as small growths of skin that some people develop on the face, neck, armpits, and body folds like the groin. They are known to be painless and do not cause any sort of discomfort. Moles, skin tags and other such skin defects are quite common on the face and body.

Does it cause pain?

Yes. Some people report pain associated with the removal of warts, due to the elimination of the deep root system that warts sometimes have. Others report little or no pain or discomfort. Mole removal is generally considered painless. It should be remembered that when moles, warts and skin cancers are treated and removed by freezing, acids, lasers or graftical removal there is frequently intense pain associated with the procedure.

How does skin tag removal work?

The method is quite popular, because it removes the tag safely and without causing any pain. The acid in the vinegar destroys the tissue that forms the blemish; however the surrounding skin is not damaged during this treatment.

Some people caution you to use organic apple cider vinegar, but many people claim that a cheap quality vinegar is as effective in removing blemishes as any other costly varieties.
