Kate Somerville Mega-C Dual Radiance Serum

What is it?
'A supercharged face serum for a double dose of radiance. This revolutionary, high-tech radiance serum is packed with 10 percent vitamin C and youth-enhancing bioactive omegas 3, 6, 9, and 7. This two-phase system is divided in the dual-chamber to preserve purity and potency of ingredients until released. It improves the appearance of dark spots and discoloration, evens out skintone, and brightens the complexion to promote an all-around healthy radiance and glow. Recommended for nightly use, it replenishes skin’s natural lipids and restores the barrier function to soften skin texture and improve moisture retention.'

Who is it for?
Anyone concerned with a lack of radiance, dullness, uneven skin tone and mild pigmentation.  

What’s in it?
Omega formula: Water, Neopentyl Glycol Diethylhexanoate, Propanediol, Methyl Glucose Sesquistearate, Glycerin, Cetyl Alcohol, Diisopropyl Dimer Dilinoleate, PEG-20 Methyl Glucose Sesquistearate, Fragrance (Parfum), HDI/Trimethylol Hexyllactone Crosspolymer, Polymethylsilsesquioxane, Phenoxyethanol, Magnesium Aluminum Silicate, Borago Officinalis Seed Oil, Tocopherol, Elaeis Guineensis (Palm) Oil, Xanthan Gum, Caprylic/Capric Triglyceride, Helianthus Annuus (Sunflower) Seed Oil, Linoleic Acid, Linolenic Acid, Oryza Sativa (Rice) Bran Extract, Rosmarinus Officinalis (Rosemary) Leaf Extract, Calcium Pantothenate, Niacinamide, Disodium EDTA, Ethylhexylglycerin, Hippophae Rhamnoides Oil, Lecithin, Maltodextrin, Pyridoxine HCl, Silica, Sodium Ascorbyl Phosphate, Sodium Benzoate, Sodium Starch Octenyl Succinate, Tocopheryl Acetate, Tocotrienols, Adenosine, Sea Whip Extract, Citric Acid, Sodium Hydroxide

Vitamin C Formula: Isododecane, Ascorbic Acid, Ethylhexyl Hydroxystearate, Polysilicone-11 

Possibly acne/allergy/troubling for some ingredients?

Natural? Organic? Man made? Vegan?
Man made

Tested on animals/sold in China?

What's not in it?
mineral oil

How do you use it?
Apply to freshly cleansed and toned skin in the evening before moisturiser. You dispense one pump from each of the two chambers into the palm of your hand, swipe across with your other palm and apply.

What’s good about it?
Immediate gratification ahoy. This works, both on a superficial level and throughout the day.
Some vitamin C products can be drying or cause too much redness on the skin. This doesn't do that for me. The vitamin c level is 10% and it is dispensed separately from the Omega section which is sea buckthorn oil pulp, an oil heavy in omega 3, 6, 9 and 7. The omega section also contains vitamin e, which helps reactivate vitamin c, essentially super-powering it if you will, whilst providing antioxidant, soothing and moisturising side-effects. They work very well together, one stimulating and active, one soothing and protective.
Skin remains healthy looking with a great glow for the day.

What’s not so good about it?
I personally found this to have a bit of a kick so if you have sensitive skin I would definitely try first. (If you can)
It doesn't make me red at all, but I definitely feel it when I apply it.

Where to use in your routine?
As serum, after toning, before moisturiser.

Exchange rate – does it punish the UK?
Kind of, because you have to order in $. Between customs and shipping you end up paying dollar for pound. (approx!) Better value than a lot of serums available in the UK market regardless.

Kate Somerville Mega-C Dual Radiance Serum is $90.00 and available on


  1. Very informative Caroline! Thanks for sharing. Is there a perfect serum to try for a first timer to serums?!

  2. This is going on my Sephora wish list for my Orlando trip :D I'm so excited for Sephora, my husband not so much ;) mwahaha!

  3. I've always wanted to try a Vitamin C Serum, I just didn't know which to get

  4. Hello Caroline

    I have the age arrest serum I was going to get theMega C but the age arrest was for both day and night have you tried that as well? Do you like this better? It's going on my list now since you know you can't have too much skincare and since I've gone through the blog from start to finish now addicted.

    1. Curious about this as well ☺ heard good things about age arrest and wonder which is the best if you had to choose.

  5. This brand is expensive but I got a couple of things from her on my last trip to the U.S. It's very good.
    Thank you for all the great info.


  6. Unfortunately KS products are not allowed to The Netherlands. I've tried thru every online chanel available to no avail. I've sent pleading emails and to KS website and other beauty depots to change policy or start stocking her products but up to now it's still only a wet dream.
    My next trip to the California will have to include a mexican food binge and a total KS extravaganza. I dont understand why she doesn't ship to Holland?

    1. Hi was just reading your comment and wondered if you had investigated using a parcel forwarding company? Here in New Zealand we have the same problem. I use MyUS.Com. They will give you a personal address at their US warehouse that you can have your parcel sent to. They then forward your parcel on to your home address for a small fee and shipping charge. Works really well. Good luck!

  7. Why is this an evening treatment? Could you use it in the morning?


    1. I was wondering this also!
      Is it because of the oil chamber?

    2. I would like to know as well please? I use the skinceuticals plorentin in the morning. I thought vitamin c was for morning use?

  8. freaky coincidence, i'd just spent a solid amount of time researching this very product & reading all the sephora reviews then boom, inbox caroline hirons

  9. Caroline, when you use it am or pm?

  10. Here's an odd question (from left field)....why do you have the category "Sold in China"? Thanks and have fun the L.A.

    1. To be sold in China, products must be tested on animals

  11. Out of interest I thought I would see if this was reviewed by Paula Begoun. It isn't (yet) but have you seen her review of Nourish??!!
    Oh dear......

  12. how come every useful ingredient is listed AFTER parfum in the omega inci list? parfum is usually around 1% so everything that comes after that is pretty much pointless, isn't it? am I missing something?

  13. Hi Caroline!

    i just ordered a 20% Vitamin C serum 2 days ago right before this post posted :( i wonder if it's too strong? i never used a vitamin C serum before so i'm a bit wonder which level i should start off with.
    also can i use Vitamin C serum in the evening in conjunction with Retinol serum?

    thank you!

    PS: this is the ingredients list of the vitamin C serum i ordered. Would you "approve" it?
    (and this is the page i bought my serum:

    Water, Ascorbic Acid, Alcohol, Sodium Lactate, Ethyl Ascorbyl Ether, PEG-60 Hydrogenated Castor Oil,
    Butylene Glycol, Phenoxyethanol, 1,2-Hexanediol, Sodium Hyaluronate, Bis-PEG-18 Methyl Ether Dimethyl Silane,
    Diethoxyethyl Succinate, Carthamus Tinctorius (Safflower) Flower Extract, Caprylyl Glycol,
    Camellia Sinensis Leaf Extract, Xanthan Gum, Glucose , Citrus Aurantium Dulcis (Orange) Oil,
    Beta-Glucan, Adenosine, Glycerin, Caprylhydroxamic Acid, Sodium Metabisulfite, Zinc PCA,
    Rosa Davurica Bud Extract, Panthenol, Niacinamide, Ammonium Acryloyldimethyltaurate/VP Copolymer,
    Liquiritigenin, Tocopheryl Acetate, Lecithin, Caprylic/Capric Triglyceride, Ubiquinone, Diisopropyl Adipate

    1. I'm not an expert, nor do I claim to be, but I would NEVER put that on my skin. My skin is VERY dry. Alcohol is the third ingredient. There's also orange oil which is another trigger for sensitive skin. There are conflicting reports on alcohol in skincare, some studies show that it will kill your skin cells, while others show that it actually helps the ingredients penetrate better. I personally don't want alcohol in my skin care because it dries out my skin. Let me know how you get on with it though.

    2. oh gosh. thank you for pointing out the alcohol. how could i even miss out that when i was reading the ingre. list >_< my skin & alcohol are not friends either -_- too bad. i will have to find another thing to used then & give this 1 to my friend instead.

  14. Ah, I still need some Vitamin C in my life, so I will look into this.

  15. Can you please do a review / share your opinion on The Body Shop Vitamin C glow boosting moisturiser?

  16. Definitely going to be getting this on my next trip to the states I love me some vitamin c. Though I am loving kiehls line reducing concentrate at the moment which is 10.5% vitc and goes warm on the skin

  17. Would you compare this to Kiehl's serum "Powerful Strengh Line-Reducing Concentrate", that claims to have 10.5% of pure vit.C?

    Here's the product:

    And here's the ingredients: Propylene Glycol, Cyclopentasiloxane, Ascorbic Acid, Glycerin, Cetyl PEG/PPG-10/1 Dimethicone, Dimethicone Crosspolymer, Lauroyl Lysine, Acrylates Copolymer, Adenosine.

    No oil, fragrance or alcohol... (although it has some silicone).

    1. Yes, I am using the Kiehl's one now too! But it's not easy to spread which means I wind up using more. So I am looking for an alternative day Vit C serum.

      Currently debating between KS and Algenist's Genius Ultimate Anti-Aging Vitamin C+ Serum.

      Caroline, please compare! I am curious which is most effective in terms of antioxidation and prevention/protection. If Kiehl's is more potent/effective I would stick to it despite it's lack of spreadbility!
