How does vitamin c lighten skin? Vitamin C works explicitly to inhibit the production of Tyrosinase, thereby shedding light on pigmentation. So yes, when you apply it topically, it serves as a great skin-lightening warrior. It also works to prevent the skin from photodamage and dark spots caused by UV exposure.
Does Vitamin C Affect Skin Color? No. Vitamin C helps fade hyperpigmentation caused by the overproduction of melanin, but it won't change the natural color of your skin. It will lighten darkened areas caused by overexposure to the sun, free radicals, heredity and hormones.
4 weeks is usually the golden rule for beginning to see changes - it's allowed your skin to go through at least one renewal cycle with this skin-changing ingredient. At this point, your skin should have a subtle change in radiance, which is something you'll notice will stick around as long as you keep using Vitamin C.
Vitamin C does not lighten the skin permanently. It's important to have a non-toxic and nourishing skin care routine, regularly use sunscreen and protect your skin from UV rays to maintain long-term results.

Ascorbic acid oxidation
As you may already know, vitamin C in the form of ascorbic acid (specifically L-ascorbic acid) oxidises easily. This is when it decomposes and turns into a number of other substances that likely have much less benefits for skin, and it gradually darkens in colour during this process.
Many women complain of skin darkening after applying Vitamin C serum. It is probably because they fail to layer it with a hydrating moisturizer. Leaving the serum alone on the face allows it to react with the oxygen present in the air.
While most people can tolerate daily use of vitamin C serum, some people may experience redness, irritation, or even breakouts. If you have sensitive skin, it's important to start slowly when using a vitamin C serum. Begin by using it every other day, and gradually increase to daily use if your skin can tolerate it.
Nearly across the board, dermatologists recommend incorporating vitamin C serum into your morning routine (as opposed to using it at night). The reason for this recommendation relates to its ability to protect the skin.

Dr. Chiu warns that because vitamin C is a skin-care “active”—meaning it's particularly potent—applying too much of it on your face can potentially lead to more breakouts or irritation. Keep it to a max of two applications a day when a formula that has no more than 10% vitamin C each time.
