Pardon the ignorant question, but when I look at some of these products, I can't tell if they're designed to be used on the whole face (or an entire area) or on a targeted darkened blemish spot. I'm kinda confused by generic descriptions and product names.
Can someone help to explain it better or shed some light?
I have recently developed a nasty acne scar near my chin and I'm trying to navigate the confusing world of sun spots, age spots, lighteners, brighteners, and bleaches. I know time is of the essence.
