Glutathione and vitamin C are both antioxidants used for brighter, more even skin. People often ask which one to pick. The real answer: they work best as a team.
How they differ
Vitamin C (ascorbic acid and its derivatives)
- One of the most researched skincare antioxidants
- Helps brighten and reduce the look of dark spots
- Supports collagen, so it also helps with fine lines
- Some forms (pure L-ascorbic acid) can sting sensitive skin and oxidise quickly (turning orange)
Glutathione
- Your body’s master antioxidant
- May help balance pigment production for a more even tone
- Generally gentle on the skin
- Has less research in skincare than vitamin C
Side-by-side
| Vitamin C | Glutathione | |
|---|---|---|
| Research in skincare | Extensive | Smaller studies |
| Brightening | Yes | Yes (modest) |
| Collagen / anti-ageing | Yes | Limited |
| Gentleness | Some forms can sting | Usually gentle |
| Stability | Oxidises easily | Can also degrade |
| Best time | Often morning, under sunscreen | Often night |
Why they work better together
Glutathione helps recycle vitamin C so it stays active longer, and vitamin C helps support glutathione. That’s why many brightening products, and many oral supplements, combine the two.
A simple routine using both
- Morning: cleanser → vitamin C serum → moisturiser → sunscreen SPF 30+
- Night: cleanser → glutathione cream
Or choose one product that already combines them.
Which should you pick if you only want one?
- Anti-ageing and fine lines as well as glow → vitamin C
- Sensitive skin, want gentle brightening → glutathione
- Want the simplest routine → a product that contains both
The bottom line
Vitamin C has more research; glutathione is often gentler. They support each other, so a combination is usually the smartest choice. Whichever you use, sunscreen matters most. See also glutathione vs kojic acid.
