Radiant C Serum
Revitalise your skin and combat visible signs of ageing with our Radiant C Serum. Formulated using a oil soluble version of Vitamin C called Tetrahexyldecyl Ascorbate that is easily absorbed into the skin and resistant to oxidation. Combined with Hemisqualane, a new biotech ingredient derived from sugarcane that locks in moisture to the skin, this lightweight formula will illuminate your complexion, smooth away fine lines, and leave your skin looking firm and radiant. Suitable for all skin types.
The scent of this serum is a subtle sweet citrus mix, delicate enough to make it an enjoyable sensory experience that won't linger on the skin.
Radiant C Serum underwent testing at Shannon Applied Biotechnology Centre to assess its effects on the skin, with a focus on how it acts as an antioxidant and how it boosts collagen production.
The results show that when compared to skin cells without any treatment, Radiant C Serum protects the outer skin cells against oxidation which can cause damage in the cells and speed up the ageing process.
Additionally, the data shows that Radiant C Serum encouraged the production of collagen in the inner skin cells. At a concentration of 1 mg/mL, there was a 25% increase in collagen. Collagen is important for keeping the skin firm and elastic. When it breaks down, it can lead to fine lines and wrinkles as a part of the ageing process.

I never had a proper skin care routine before Doctrine. I started with the balm which made my life so much easier, the moisturiser is a must (even I always had it), but the serum for me was never part of the equasion. Since I found the other two product so good and so perfect for my needs, I decided to get the full set. Well... I have only been using the serum for a few days and I swear I can already see a difference. Great stuff!
Beautiful products, caring for my skin has reached a new level 🥰
Having wanted to support irish business this Christmas, I bought my wife both the Radiant C Serum and the Divinity Cleansing Balm. After 3 weeks of using both products she has abandoned her old skin care regime for Doctrine. The gift went down so well that they both now sit on her bed side locker. Will definitely be buying again.
Doctrine is an extremely luxurious product line. Having purchased both the divinity cleansing balm and radiant C serum, I can honestly say I have been converted!
beautiful serum, leaves my skin so soft and hydrated. Smell is so nice. Really likethe pipette. I have only been using it 2 weeks but my skin is brighter
Absolutely love love love your products!!! 🩵
Great product and texture :) I am super happy
Very nice product! :)
This is my favourite vitamin c serum, the oil is so light and gives a great glow
I love my Vitamin C Serum, it's lightweight & absorbs quickly & helps brighten my skin. Thank you. Kathryn.
I absolutely love this serum. I’ve been using it every morning for the past few months, and the difference in my skin has been remarkable. My complexion looks noticeably brighter, smoother, and healthier, with an overall refreshed appearance. What surprised me most is how versatile it is. In addition to its skincare benefits, it works incredibly well as a conditioner for my beard. It leaves my beard feeling softer, more manageable, and well nourished without feeling greasy or heavy. It’s become an essential part of my daily grooming routine, and I genuinely look forward to using it every day.
This goes on great, smells lovely and makes my skin brighter and perkier. I really like this!
I think this is my 4th or 5th serum?! I cannot be without it for long. Its beautiful and cares for my skin hugely. Delighted to be supporting Irish made goods too 🥰
Really lovely texture vitamin C. Applies and absorbs easily. Haven't used it long enough to see any major difference in my skin yet except for it gives me a lovely daily glow.
This product is so nice, non greasy and leaves skin feeling nourished, soft and smooth.
The only Vit C serum you need - my third bottle
Lasts really long and use it everyday. Great texture, just a lovely product
Really love the serum, great texture and scent, can see an improvement in my skin
I love Doctrine serum, thank you.
I absolutely love this product, it really suits my dry skin. I love to buy from Irish skincare brands, and I am keen to try more from this brand. Super fast delivery too. Definitely recommend this gorgeous brand.
I'm using the C serum & I like it except I find it takes too long to absorb before my moisturizer.
Love this serum it feels so nourishing
Only been using 2 weeks but I’m hoping in time my skin will look brighter. I wear it under my Elemis collagen factor 30 moisturizer and feel my makeup goes on smoother so that’s a plus Here’s hoping in time it will fade my pigmentation 🤞🤞
Amazing product giving such a radiant glow to my skin so quick
Love this serum. It is an oil but it is not greasy under make up. Citrus smell is gorgeous
Leaves my skin Dewy and glowy
This is my second time to purchase the Vit C oil, something I never do unless I think it is worth while. I cannot get over the difference this has made to my skin. The redness and blotchiness that I assumed were just there for life, has all but disappeared. Dark marks have cleared up and I feel my makeup goes so much better. I repurchased before I ran out to make sure I didn’t miss a day. Game changer!
Gorgeous product!
My daughter loved the divinity serum so much she told me she was running out and couldn’t wait to get it again, and I’m delighted she’s into this quality product.
It’s Early days but so far so good it’s not irritating my skin like other vitamin Cs
The best serum by far. My skins feels and looks smooth, has healthy glow, works perfect with my other daily skincare products and foundation l use looks better and stays longer.
Pleasant to use - what makes it special?How long should it last Thanks Catherine
Store owner replied: Hi Catherine, we are delighted that you are enjoying using our Radiant C Serum. Vitamin C serums are best used in the morning after cleansing and before your moisturiser. We use an oil soluble version of Vitamin C that is gentle and easily absorbed so feel free to use it every day and don’t worry about it interacting with other products. Vitamin C is a great antioxidant so will help protect your skin against pollution as well as stimulating collagen production and giving a bright radiant complexion. You only need to use a few drops a day so this product should last you 6 months. We hope you continue to enjoy using it!
There is so much I love about this serum! First off the scent is amazing and really adds to the sensory experience. The texture is gorgeous, it's like a very light oil that absorbs instantly. A little goes a long way. The pipette is great and fills with just the right amount. I always have vitamin c in my routine and feel this brand maintains skin clearness and glow. I can't wait to see what's next for Doctrine Skincare.
Love it
On my second bottle of Doctrine Vitamin C serum, enjoying the fresh feel on my skin each morning and have noticed my skin is visibly smoother and fresher since I started using the serum, thank you.
It’s my first time trying a serum and I wasn’t sure what to expect…. I love it!! You only need a tiny amount and it feels really smooth on the skin and absorbs immediately so no oily residue. My skin looks a lot brighter and moisturised since I’ve been using the serum. The scent is gorgeous too.
This is a fabulous serum. It smells divine and leaves your face hydrate. You can't go wrong with this serum.
I've been using the Radiant C Serum by Docterine for a few months and love it. It absorbs quickly, leaves my skin smooth and hydrated. Works well under makeup and doesn't irritate my sensitive skin. Highly recommend!
Really happy with purchases and service. Very speedy delivery and both the serum and the cleansing balm are gorgeous to use 💕
Really nice serum which is non greasy, smells Devine without being overpowering. Although the bottle is beautiful I would love to see into the bottle to know when I need to order the next one. Maybe a line from top to bottom just enough to see when it’s getting low. Thanks for creating beautiful products.
