What Is Kakadu Plum, and Why Natural Vitamin C Is Good for Your Skin

Published June 22, 2026 · by CMe CheerTsuMe · ~14 min read

Have you ever bought a vitamin C serum only to find it left your skin stinging or red, or used it for a long time without seeing the change you were hoping for?

That feeling isn’t unusual, because some concentrated forms of vitamin C may not suit every skin type, especially for those with fairly sensitive skin or who have been through a period of easily irritated skin before.

That’s why many people have started turning their attention to Kakadu Plum, a natural vitamin C that’s gaining interest in the skincare world.

What Is Kakadu Plum?

Kakadu Plum has the scientific name Terminalia Ferdinandiana and is a native fruit that has grown across the land of Australia for thousands of years.

This fruit is well known in nutritional science for having one of the highest levels of natural vitamin C (Ascorbic Acid) in the world, and botanical and skincare researchers have continued to study its properties with great interest.

Indigenous Australians have known and used Kakadu Plum in daily life for a very long time, before the modern beauty world brought Kakadu Plum Extract into use as an ingredient in skincare products.

How Vitamin C Is Good for Your Skin

Vitamin C, or Ascorbic Acid, is an antioxidant that our skin needs.

When skin faces pollution, sunlight, and accumulated stress each day, free radicals slowly damage skin cells, leaving skin looking dull and less radiant than it should be.

Vitamin C works to protect skin from free-radical damage and helps support the skin’s natural process of caring for itself, so skin looks brighter and more luminous in a natural way, not bleached or forced.

In addition, vitamin C also helps protect the skin when used together with sunscreen during the day, making your skincare routine more effective.

How Is Natural Vitamin C Different From Synthetic Vitamin C?

This question is fairly debated in the skincare world. Here’s a straightforward summary to make it clear.

Synthetic vitamin C such as L-Ascorbic Acid has a clearly measured and controlled concentration with plenty of research behind it, but it also has properties that can make some people’s skin feel irritated, especially at the low pH that’s necessary for its effectiveness.

Natural vitamin C from Kakadu Plum comes alongside other compounds naturally present in the plant. Many people with sensitive skin feel their skin responds better to it, and in some formulations it may also be more stable.

The thing to know is that neither form is conclusively “better.” The best choice is to see how your skin responds, and who the overall formula of that product was designed for.

How to Choose a Vitamin C Serum That Suits Sensitive Skin

Sensitive skin doesn’t mean you have to avoid vitamin C altogether. You just have to choose the right one.

What to look at before deciding:

1. Look at the whole formula, not just the hero ingredient Vitamin C works better when it’s alongside complementary ingredients, such as Niacinamide, which helps care for skin so it looks more even, or Alpha-Arbutin, which helps skin look brighter. A formula with several ingredients working together often gives better results than vitamin C on its own.

2. Look for numbers from real testing A good brand can tell you who it tested with, how many people, for how long, and at which institute. Numbers that appear out of nowhere with no source should be questioned first.

3. Always patch test first Whatever the product, if your skin is especially sensitive, try a patch test on the inner arm for 24-48 hours first. It takes very little time but gives you far more confidence.

4. Use it correctly A vitamin C serum should be applied after cleansing, and if used during the day it must always be followed with sunscreen SPF50+, because vitamin C works best alongside sunscreen to protect the skin.

We want to emphasise that this number comes from the testers’ self-assessment, not a clinical measurement, and results depend on each individual’s skin condition. But it is a real number from a real test, not an estimate.

The Real Story Behind CMe — Cheer, Founder

The reason CMe’s serum uses natural vitamin C from Kakadu Plum instead of a high-strength synthetic form comes from founder Cheer’s own experience. After a night of washing her face three times with foam, her skin’s protective barrier was damaged, leaving it reactive to many high-strength active ingredients. That experience shaped CMe’s approach: choose a gentler natural vitamin C over chasing the highest possible concentration. Read Cheer’s full story ›
