light halo and bbl could work for certain stretch marks I would need to see photos to determine. I would suggest proper skincare (see link) and at home dermarolling. stretch marks need lasers, microneedling, and sometimes medical tattooing. it is best at home to be using products that stimulate collagen and improve discoloration. see emeragecosmetics.com for products like vivatia foam, emerageskin roller with anteageMD ampules to be used twice weekly, phyto plus by skinceuticals, cosmelan 2 cream, reve skin 1.0 retinol, and ISDIN lactic acid body lotion. In office radiofrequency like fractora, skinfinity, and venus viva work well. consult with us, we do free skincare consults daily at emeragecosmetics.com. Best, Dr. Emer.
