i'm asian with very fair skin that freckles easily. I'm in my late 30's and have light brown/green eyes and medium brown hair. I'd like to tighten my skin a little bit (increase collagen) without doing a procedure that is drastic. I've heard that IPL increases collagen and tightens skin a little bit. I've also heard the same of a low-grade TCA peel. Which is better for me? I have a keloid scar from when a dermatologist removed a mole. Will that affect which procedure is best? For TCA peels-should I do a series of 8% peels? Or how many IPL's?
