When it comes to actinic keratoses (AKs), or pre-cancerous lesions, we offer laser treatments and cryotherapy. Cryotherapy treats AKs by submersing them in liquid nitrogen; this cold or freezing therapy targets the mutated skin cells of AKs, triggering the body to slough them off. Beneath, new, healthy skin cells generate and you’ve prevented a pre-cancerous lesion from developing into skin cancer down the road. For ongoing skin cancer prevention, we always recommend a strict daily sun protection regimen.
