IPL improves skin texture and color. It does this by changing pigment and capillaries in the dermis as well as encouraging new collagen production. Anything placed below the dermis is not affected by IPL
You should be able to safely get IPL/ Photofacial treatment to improve redness, pigmentary irregularities and texture, as long as the "golden threads" in your cheek are not in the superficial skin layer. I cannot imagine why they would be.
