Vitamin C helps lighten highly pigmented skin, but it doesn't affect the surrounding skin. All you need to do is clean your skin, then use 5-6 drops of a vitamin C serum on the area. You can apply it before you apply sunscreen in the morning. Just treating the dark areas will allow you to pick the parts of your skin you want to lighten. Plus, it can be easier on your budget, since you're not using it over a larger area. Typically, you apply a small amount just to the affected area, either in the morning or at night.  Look for ingredients like azelaic acid, 2% hydroquinone, kojic acid, glycolic acid, retinoid, and vitamin C. Usually, these are labelled as "spot treatment" serums. Be careful purchasing these serums online. Make sure you buy a spot treatment or medication formulated in a country with good regulatory practices, such as the U.S. or U.K. Medications produced without regulation may contain harmful ingredients, such as steroids or mercury. While spot treatments are great, a serum that works over the whole area can make your life easier. It can make your skin tone more even overall, not just lighten the darker areas. You generally apply serums like this once or twice a day. Blemish patches are made specifically for dark spots. You just put them over the area, and it helps lighten discoloration. Pimple patches may also help, as they'll unclog pores and lightly exfoliate the area. You can find these online or at most beauty stores.
