Debunked! 5 Common Myths About Vitamin C in Skincare

January 22, 2026

Introduction

Vitamin C is a well-known superhero when it comes to skin recovery, brightness and glow. But with its fame comes a fair share of myths. Is it really as unstable as everyone claims? And are all vitamin C products alike? Let's find out.

01.

MYTH:
The sun is your enemy while using vitamin C skincare


THE TRUTH:
These two can make good friends eventually. 

There’s a common misconception that vitamin C and sunshine don’t mix. In reality, vitamin C is your skin’s skin’s best friend in combating sun damage.


Vitamin C works as an antioxidant to neutralise free radicals caused by UV exposure. Pair it with broad spectrum sunscreen, and you’ve got a dynamic duo that protects, brightens and supports your skin’s resilience. 


Just remember that vitamin C enhances your defence—but it doesn’t replace your SPF.

02.

MYTH:
Vitamin C will make the skin lighter, stealing your tan


THE TRUTH:

It won’t lighten your skin, but will even out your tone.

Worried that vitamin C will strip away your sun-kissed glow? Don’t be. Instead of lightening your skin, vitamin C helps to improve the look of skin tone irregularities and hold back the future appearance of dark spots.



Think of it as a glow booster that restores your skin’s natural radiance and keeps it looking healthy, whether you’re pale, deeply tanned or somewhere in between. 

03.

MYTH:
Vitamin C irritates the skin


THE TRUTH:

When formulated wisely, it’s gentle enough for all skin types.

Yes, L-Ascorbic Acid can sometimes be too intense for sensitive or reactive skin. However, gentler derivatives (such as Ascorbic Acid Glucoside) deliver the same benefits without the irritation.


Vitamin C can even support skin recovery. This can be especially beneficial after those long, dark winter months to give your skin back its radiance, and keep the external stressors from stealing it away throughout the year.

04.

MYTH:
All vitamin C products are the same


THE TRUTH:
Formulation is everything.

Not all vitamin C products are created equal. From stabilised derivatives to pure L-Ascorbic Acid, vitamin C comes in many forms—which is why the type of vitamin C and the overall formulation play a huge role in its effectiveness.


Seek out stabilised forms like Ascorbyl Glucoside and steer clear of formulas with unnecessary fillers or potential irritants such as parabens, petrochemicals, synthetic colourants and artificial fragrances. 

05.

MYTH:
Natural skincare products don’t contain effective forms of vitamin C


THE TRUTH:

Not necessarily.

This myth couldn’t be further from the truth. Many natural and organic skincare brands now use stabilised, potent and bioavailable forms of vitamin C that deliver impressive results without compromising on clean ingredient standards.


In fact, MÁDARA natural skincare formulations with vitamin C are dermatologically tested and proven to deliver powerful results. Not only are they effective, but they’re also gentle on your skin and crafted with sustainability principles in mind.


With key ingredients like antioxidant-rich brown algae extract, deeply hydrating hyaluronic acid and a stabilised form of vitamin C, these formulas are designed to:

  • Reduce the appearance of dark spots
  • Brighten dull complexions
  • Help restore glow
  • Provide antioxidant defence

A tip from MÁDARA dermatologists

1. Avoid using vitamin C together in the same routine as acids, since that can irritate your skin.


2.
Sensitive skin? Go natural. Ascorbic Acid Glucoside, which is at the heart of our Vitamin C Illuminating Recovery Cream, possesses all the positive qualities of pure vitamin C, but is far gentler to the skin.
