Postoperative wound care
It is crucial that the laser-treated area be kept moist by the application of copious amounts of ointment and moisturizer prescribed by the dermatologist to promote reepithelialization.
Avoid whitening or acne face wash, exfoliators, sunblocks, sunblock containing day creams, antiaging or whitening creams, makeup, skin bleaching, any kind of facials, strong sun exposures and too much heat.
Oral antibiotics/ oral antivirals/ pain killers can be given.
Treated Area After 1 Month Of Procedure
After crusting, the treated area looks pinkish.
Treated Area After 2-3 Months
The pinkish area starts gaining pigmentation or skin color starts coming back.
Post Inflammatory Hyperpigmentation (The color that starts coming back in the laser treated area is not blending with the surrounding normal skin color but is a bit darker). It is a temporary complication that can be taken care of by using dermatologist prescribed whitening creams or a few sessions of Q switch Nd Yag laser(pigment breaking laser) or Intense Pulsed Light can take care of this problem.
Persistent erythema or redness (The treated area remains pink, does not blend well with the surrounding skin color for some time)
Moles can come back and can be removed in another laser session. Patient has to pay extra for this subsequent session.
How many sessions are required to get rid of moles?
What is the minimum time interval between 2 laser sessions?
About 2 to 4 months.
Spot Testing Before Treating Moles With Ablative Laser
One or two moles are treated in one sitting and the response of the skin is monitored after a period of 1-3 months. Depending on the skin response, next treatment addressing the whole face is planned.
Spot testing is recommended in very dark and wheatish skin complexions but it is not a must.
