Why do I still have dark spots after cryotherapy for seborrheic keratosis removal?

Question

Dr. treated several SK’s via cryotherapy on my neck, some treated twice. Now a month later there are still brown spots, some pin-head sized and some larger. Doctor said they will fade with time. Is that true and if so, how much time? Can I do something else to even out the skin tone? Thank you for your advice.

The amount of time it takes for fading of pigmented spots following treatment to fade will depend on several factors.

Location of treatment - cell turnover is fastest on the face and slower as you move down on the body.  It could take months. (Do use sun protection.)

Genetic background - if you have genes with darker pigment potential, it will take longer than if you have a Scandinavian background.

Skin care - keep the area moisturized and don't use scented products or perfume in the treated area.

You can expect months for fading to occur.

This is difficult to answer without pictures. Dark spots can be improved with a combination of Cosmelan, lasers, Aerolase, microneedling/prp, skin lightening, peels, and skin care. Sun protection is essential. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer

Hyperpigmentation or darkening of the skin is a common side effect or risk with cryosurgery. Your skin type also plays a major factor in whether you’ll darken as a result of a skin procedure.  It is common, will most likely fade or lighten with time. To speed up results a topical regimen of hydroquinone can be added before or after treatments.

Thank you for your question.  Pictures would have been incredibly helpful.  It sounds like you have Post Inflammatory Hyperpigmentation (PIH).  If so, you have multiple options   If you are a skin type I-III, an series of IPL photofacials may be helpful.  We have also been very successful using the PicoSure laser with the FOCUS and / or Flat Lenses eliminating hyperpigmentation with a series of treatments.  FOCUS lens treatments have the extra benefit of reducing fine lines and wrinkles.  This is one of our go to treatments for patients older than 40 and worried about the signs of aging.  This laser is safe for all skin types.  Start with sunscreen every day!  Once you have treated your hyperpigmentation to your satisfaction, you will probably need a follow treatment every 6 to 12 months depending your level of re-pigmentation.  Best of luck.
