Environmental factors such as sun, stress, and pollution can cause skin pigmentation changes and often results in what we call sun spots and age spots, even blotchy redness.  Research has shown that using a treatment infused with vitamin C is one of the most effective ways to treat these skin discolorations.

I recommend:

MURAD Essential-C Collection
Start with the cleanser, and follow with the toner and daily renewal complex, finishing up with the SPF 30 moisturizer.  Using these in combination can reduce skin clarity and tone within a few days.  (I noticed results in about 3 days).

REMEMBER, the active ingredient you are looking for is VITAMIN C, so whether you choose these or other products, go for ones with a vitamin C infusion!
