Whitening serums for scarring/red marks?

I have noticed a recent increase in the number of skin whitening products on the market, and was wondering if anyone has had any experience/success with using whitening/brightening serums or other solutions as a treatment for red marks and acne scarring?

SMALL BUMPS...???

i've just recently started using bp gel (DDF's 5% w/ tea tree oil) and i've changed my regimen entirely, and i'm noticing alot of small non-acne-looking bumps all over my skin, especially on my forehead. they look almost like blocked pores, about the size of a small blackhead, only they dont seem to have bacteria in them or anything.. none of them have gotten bigger or felt irritated. my skin is almost completely clear except for a couple of scars that are still fading, but the texture is all bumpy and rough and i can't figure out why. has this happened to anyone else??

here's what i've been doing for the past week or so: (a.m and p.m)

- cleansing w/ SpectroJel (for sensitive/problem prone skin)
- wait 5-10 mins after patting dry (i never used to, but dan recommends it... anyone know why?)
- apply 5% bp w/ tea tree
- once dry, apply oil-free moisturizer (i've been using mary kay's velocity moisturizer for a while, never a problem before)

- when skin is extra-dry, i use jojoba oil at night only (i've used it in the past when the cold weather makes my skin really dry, and i know it doesn't make me break out)
- every other day or so, i'm using DDF's Pumice Acne Scrub w/ 2.5% bp, which is fantastic and makes my skin feel soft, but doesn't seem to be getting rid of these little bumps

someone please help!!
