10% Vitamin C
Brightens skin + targets uneven tone
After cleansing, apply 1–2 pumps to the face and neck, avoiding the eye area. Gently press or smooth into skin until absorbed.
Follow with a hydrating serum and moisturizer to lock in benefits. Always finish with broad-spectrum SPF as your final step to protect and maintain results.
If you're new to Vitamin C, start with every other morning. Once your skin adjusts, you can use it daily.
Patch Test:
As with any skincare, we recommend patch testing before first use. Apply a small amount to your neck or inner wrist and wait 24 hours.
Avoid using on broken, exfoliated, or irritated skin. If you have sensitive or reactive skin, patch testing is especially important.
Start with 2–3 uses per week and increase gradually as your skin builds tolerance. Discontinue use if any sensitivity occurs.
Recycling:
Please rinse the bottle and remove the label before recycling. The cap is not recyclable at this time.
Three clinically studied forms of Vitamin C—3-O-Ethyl Ascorbic Acid, Ascorbyl Tetraisopalmitate, and Sodium Ascorbyl Phosphate—work together to brighten, even tone, and protect against early signs of ageing.
Ferulic Acid
A powerful antioxidant that stabilises Vitamin C and defends against environmental stressors like UV and pollution.
Niacinamide
Soothes visible redness, refines texture, and supports the skin barrier—ideal for daily use, even on sensitive skin.
Glycerin + Plant Oils
Hydrating and softening ingredients like Glycerin, Sweet Cherry Oil, and Grape Seed Oil help balance the skin and enhance radiance without heaviness.
What changed in the updated Triple Vitamin C Serum?
We’ve listened to your feedback. The updated formula now includes an odor-neutralizing agent to address previous scent concerns. The formula has been streamlined, and the packaging is now upgraded with a lockable pump for consistent and travel-friendly dispensing.
What stayed the same?
The results you love are unchanged. Our core actives—Triple Vitamin C, Ferulic Acid, Niacinamide, and Glycerin—are all still here, working together to brighten, protect, and smooth your skin. It’s still the same lightweight, fast-absorbing formula designed for visible results.
Why does this serum use 3 forms of Vitamin C?
Each form has unique benefits and absorption rates. Using three ensures broader coverage: improved brightness, enhanced stability, and deeper antioxidant protection for all skin types.
How do I prevent my serum from oxidizing?
We use amber glass packaging to protect against light exposure. Store in a cool, dry place, out of direct sunlight, and always close the cap to maintain potency.
Can I use this serum with other actives?
Yes—this formula layers well with hydrating serums like hyaluronic acid and barrier-strengthening moisturisers. Avoid layering with strong exfoliating acids or retinol in the same routine to reduce the risk of irritation.
Customer Reviews
Overall rating: 4.3 / 5 from 16 reviews.
I love Duogen products. I use 4 of them in the morning and Triple Vitamin C serum is one of them. It is a light serum that helps hydrate too. I’m pleased with my morning and bedtime routines and with the results. I celebrated my 80th birthday last autumn and I’m happy to continue reordering!

I've been using it for over 2 years now and I'm satisfied with the results. I'm 45 and just trying to keep my skin as good as I can for a long as I can. I use it with Dr Organic moisturiser and eye cream and it all seems to work well.

Great as a first line of defense against all the pollutants in the atmosphere particularly in the city. Easy to apply and is well absorbed into the skin. For the best benefits I found this product works great with hyaluronic acid serum and a good moisturizer. I use Niacinamide as I have slightly red cheeks and nose and this moisturizer calms down any redness.

I use other duo gen products hence why I bought this. The product is a cream and not as I had expected from the title serum.
It clumps on the skin a few minutes after application.
Additionally, my face had an allergic reaction a few days after the initial use which was a little painful and sore. I thought it could have been something else so I used it again a few days ago and I had the same allergic reaction. This is so disappointing as I have loved products up until now. The reaction I have had has needed medical attention and additional treatment to resolve which will again take a couple of weeks.
