White scar on nose - cryotherapy?

Our treatments use combination therapy to improve the epidermis and dermis for most deep scars. The options available for acne scars depend on the character of your scars, in terms of topography and contour. We see atrophic and hypertrophic acne scars, as well as scars that have hypo and hyperpigmentation. We begin each scar evaluation with an assessment of scar quality and subtype. Our main concern is rebuilding collagen and that is why we use a HIDEF protocol that includes combination therapy. Morpheus 8, scar subcision, fibrous release, fractional laser, CO2 laser, Thulium laser, PDL Vbeam laser, and fractional resurfacing can be used in addition to TCA Cross and chemical peels to further improve skin. Patients should start Melarase AM and Melarase PM for active hyperpigmentation. Always begin with a consultation to decide whether early subcision should be started.

I suggest posting photos, this may require microneedling or fraxel laser with PRP. but i have had people get medical tattooing with great results.  Please make a formal consultation with an expert.  Best, Dr. Emer.

I would recommend a surgical excision of the hypo pigmented scar. Cryotherapy kills melanocytes which give skin it's color therefore the skin is white. Removal of the scar and careful suture placement will likely lessen the scars appearance.
