FDA Clearance and Clinical Assessment

The Norseld Dual Yellow D10B received U.S. FDA 510(k) clearance for specified benign vascular and pigmented skin lesions. FDA clearance does not guarantee a particular cosmetic result. Moles, warts, skin tags, and growths around the eyes require physician diagnosis before treatment; lesion-removal settings may cause crusting or require wound care.

Who Should Avoid or Postpone Treatment?

Treatment may need to be postponed or modified during pregnancy, with an active infection, open wound, uncontrolled dermatitis, recent tanning or sunburn, photosensitizing medication, a history of abnormal scarring, or an undiagnosed skin lesion. Tell the physician about all medicines and supplements before treatment.

Possible Side Effects

Temporary redness, swelling, warmth, stinging, bruising, pigment darkening, or crusting may occur. Blistering, infection, prolonged pigment change, and scarring are uncommon but possible. Contact the clinic if symptoms are severe, worsening, or unusual.
