Does Vitamin C Serum Darken Skin? Myth vs. Reality | CITTA
Introduction
If you've been on the internet recently, you must have seen, “Vitamin C oxidises and darkens your skin.” But is it another internet viral reel or another myth floating around? Vitamin C serum has gained major popularity amongst the skincare junkies for obvious reasons. It is, therefore, imperative to bust myths surrounding vitamin C.
This blog is your ultimate guide to busting the popular myth “Does vitamin C serum darken skin?” We will learn how it is a potent ingredient to target common skin concerns. And of course, we will help you choose the best vitamin C brightening serum.
Where the Myth Came From
Let’s begin by understanding where it all started. The myth perhaps originated from a misunderstanding that stated when vitamin C serum oxidises, it turns yellow or amber in colour. Especially L-ascorbic acid, which is a form of vitamin C. People viewed this colour change as discolouration and concluded that it tanned their skin.
In the internet age, it doesn’t take too long for something to travel across platforms and reels. But dermatologists disagree. While it is true that oxidised serum loses its potency and can possibly tint the skin briefly, to say it darkens the skin by promoting melanin production is completely false.
In fact, studies show that Vitamin C makes the skin brighter, and not the other way around.
The Real Science — How Vitamin C Affects Pigmentation
Tyrosinase Inhibition & Melanin Synthesis
Our skin produces melanin by using an enzyme called tyrosinase. Vitamin C bars this enzyme and slows down hyperpigmentation, brightening your skin tone. A good vitamin C brightening serum thus makes for the number one choice for treating stubborn dark spots.
UV Protection via Antioxidant Action
Vitamin C serum is known to neutralise free radicals. When you pair it with a sunblock, it shields your skin from the pigmentation caused by the UV rays. In simple words, it enhances the SPF effect.
Collagen Support for Overall Brightness
As vitamin C promotes collagen production in the skin, your skin appears visibly smooth, bright, healthy and plump.

Situations That Can Make Skin Look Darker
To be clear, vitamin C doesn’t tan your skin. However, a few mistakes in applying it can make your skin appear stained briefly. What are those mistakes? Let’s find out:
- Using expired or oxidised products: Just as we check the expiry date when purchasing medicines, similarly it is important to ensure that you don't end up buying/using expired products. If your serum’s colour changes to orange or brown, it could tint your skin temporarily. Don’t confuse it with tanning; rather, it's a reminder to trash the product.
- Not wearing SPF: Always remember that vitamin C is not an alternative to sunscreen. It amplifies the sunblock effect, shielding your skin from environmental stressors.
- Irritation → post-inflammatory hyperpigmentation: Since vitamin C is highly potent, overusing it or using high concentrations can cause irritation which may lead to hyperpigmentation.
If you’re using a vitamin C serum, don’t forget to layer it with a high-SPF sunscreen for overall protection.
