How can I treat seborrheic keratoses (SK’s) ?

There is no need to treat seborrheic keratoses (SK’s), as they are completely harmless. Still, if one does get irritated it may be treated with liquid nitrogen in most cases. At times these are treated for cosmetic reasons, generally using liquid nitrogen as well. Other treatment options include over the counter ammonium lactate cream, prescription retinoic acid creams, electrocautery, electrodesiccation and curettage, and shave excision. Still, it is important to weigh the risks and benefits of treatment as the treatment modalities carry a risk of discoloration and/or scarring. Also, even if lesions are treated, they may not fully come off with 1 treatment, they may grow back, or others may form in their place (particularly if one has a lot of them).
