Antioxidants compared
Glutathione vs Vitamin C: Which Is Better for Skin?
It’s one of the most-asked skincare questions — and the honest answer is that they’re better together than apart.
The short answer
It’s not really glutathione vs vitamin C — they’re two antioxidants that work as a team. Vitamin C helps regenerate glutathione, and glutathione helps recycle vitamin C. Used together they support radiance and an even-looking tone more effectively than either alone — which is exactly why they’re so often combined.
Two antioxidants
What each one does
Glutathione
The body’s “master antioxidant,” working inside cells to neutralise oxidative stress. Popular for supporting overall radiance and an even-looking complexion from within.
Vitamin C
A powerhouse topical antioxidant that supports brightness and helps defend against daily environmental stress. A morning-routine favourite under SPF.
The key point
They regenerate each other
Antioxidants don’t work in isolation — they hand electrons back and forth in a network. Vitamin C helps restore used-up glutathione, and glutathione helps recycle vitamin C. Together they keep your skin’s antioxidant defences topped up for longer, which is why the pairing is more than the sum of its parts.
| Glutathione | Vitamin C | |
|---|---|---|
| Best known for | Radiance & even-looking tone | Brightness & antioxidant defence |
| Where it works | Inside cells (the master antioxidant) | At the surface & in the dermis |
| Great as | A daily supplement or serum | A morning serum under SPF |
| Together | They regenerate each other — better as a pair | |
So which should you use?
Use both — ideally in one formula
If you’re choosing, don’t. The simplest, most effective approach is to get both antioxidants working together. Avara’s Glutathione + Vitamin C serum pairs them in a single step, and adding glutathione gummies supports your antioxidant status from within too.
Glutathione vs Vitamin C FAQ
Is glutathione or vitamin C better for skin?
Neither is strictly “better” — they’re complementary antioxidants that work best together. Vitamin C helps regenerate glutathione and vice versa, so combining them supports radiance more effectively than either alone.
Can you use glutathione and vitamin C together?
Yes — they’re a natural pairing and are often combined in a single serum for exactly this reason. They support and recycle each other.
Which should I apply first?
In a combined serum it’s done for you. If using separate products, apply thinner, water-based antioxidant serums to clean skin before heavier creams, and always finish with SPF in the morning.
Do I still need SPF if I use antioxidants?
Absolutely. Antioxidants support your skin’s defences, but they don’t replace sunscreen — daily SPF is the foundation of any radiance routine.
