Are there any chemical peels that don't affect or lighten freckles? ( I'm not looking to get rid of them)

I have fair skin, quite pale, with rosy cheeks and freckles scattered across my cheeks and nose, as well as on my forehead. Although I don't have anything close to acne, because my skin is so fair, any and all pimple scars are very prominent. I was hoping that perhaps a gentle chemical peel could maybe lighten those scars and uncover firmer, clearer skin, without necessarily altering my pigment or lightening my freckles. I am not very educated on this subject and I would really like some tips. Thank you!!
