    Active Ingredients
    Aloe Vera
    An antibacterial and anti-inflammatory in one, great for soothing sore patches, relaxing spots, and even protecting from harsh UV rays.
    Dill Extract
    Dill can help influence elastin production - one of the few natural ingredients to do so.
    Ferulic Acid
    The best thing that ever came from bran, ferulic acid is a powerful anti-oxidant that prevents free-radical damage and stabilises essentials like vitamin E.
    Hyaluronic Acid
    A humectant, it draws water to the surface of your skin, keeping it soft, supple, and healthily hydrated. It’s also a helpful way to make sure other ingredients penetrate deep into the epidermis.
    Liqourice Extract
    Effective against dark spots, hyperpigmentation and acne-causing bacteria. Great for sensitive or redenned skin.
    Pantethenol (Vitamin B5)
    Panthenol is a humectant that gets to work on the stratum corneum to help reduce redness and itching.
    Vitamin C
    An essential anti-oxidant, vitamin C protects event the most sensitive skin against UV damage. And if the damage is already done, don’t worry – vitamin C stimulates useful collagen production, ideal for repair and restoration.
    Vitamin E
    A fat you can make friends with. Vitamin E is a clever fat soluble that hydrates and repairs your skin, leaving it full and fresh.
  • Give Regena C20 a gentle shake to activate. Apply a few drops to blemishes, fine lines, dark spots and areas of hyperpigmentation.

    Vitamin C is also great to use on acne and areas of inflammation and itching.

Brightens skin

Sarah Davies

Fantastic. Best serum I have ever bought. Skin feels firmer and more supple. Have been recommending this to friends who have commented on my skin :-)


This is my third purchase of vitamin c serum . I love the texture which sinks in, silky without being heavy or greasy. My skin looks more even and bright.


I love this product, you can notice the difference after a few days.


After using the product for a very few days my face feels very smooth and soft. Would highly recommend Regena C20. I use it in the morning before i put the daily moisturizer on

Lovely product had realy helped diminish dark brown pigmentation On face and neck


Unfortunately I found this serum much too strong . It actually felt as if it burned my skin. Unable to continue with it.

Arosha Honey

Best product. It really worked


Surprisingly I really liked this serum, it got rid of all my acne especially those hard lumpy ones in about two weeks. It hasn’t faded the scar from previous ones though.


It does leave skin more even and does not seem to clog pores on oily/combination skin. It has a very velvety feel to it. It seems to plump up the under eye area (dark circles) or so I have noticed in the last few weeks I have been using it. I use it once every few days so not very often.Overall I am happy with it. It is a good product so far, albeit the first Vit C serum I try.

I was looking for a serum that Contained Hyaluronic acid and I had heard great thinks about this serum, it feels lovely on the skin and I like to use at night when I wake my skin feels plumed and soft and glowing :) highly recommend this product


best value quality product

Caroline Tobiere

After the first use left my skin with a lovely dewy look, and is helping with scaring from post acne scars. I am very happy with all my purchases from Face Theory as has cleared my skin, and now able to go out without any makeup. Very happy!


Really great product, my skin looking so much brighter and even and I’ve had it just over a week. Really recommend for pigmentation/scarring! Bloody fantastic product

Daniel patrick Belgica

best to fade marks! significantly reduced my acne marks

Jessica Thomas

Skin feels amazing and perfect for dull skin to add a natural shine the next morning.

i’ve Been using this VitC serum each morning after exfoliating and cleansing, spreading a teaspoons amount over face and neck and follow with an spf40 primer. I’m keen to try and diffuse patches of Melasma and after 2 weeks I think there is a slight improvement. I can feel a slight tingling after applying but it’s not painful and I’ve had no issues such as irritation at all. I’m sure this will also brighten my skin and will remain a vital part of my routine now.

Reshma Shah

First time i bought the product after reading the reviews, i have been using for 2 weeks and i can see the improvement on my face . Skin is glowing best to put once u have cleaned your face and in the morning u only need one or two drops.

kathryn coombs

this is a great product but make sure you don't use too much and smooth it in well or it seems to react with the moisturizer and go a bit gritty. I have noticed a massive improvement in my p ores and the general texture and condition of my skin



Only using for a week -im not seeing Any results now, intigriends ok,

Lucy Morriss

It leaves skin feeling very soft and helps reduce pores. It also has helped to make my acne scarring slightly lighter. I've been using this product for a week or two now so I expect my skin to get better with further use.

Despoina Karagali

Great texture, easy to apply and so far (10 days of use) very gentle and stable. Glowy skin, does not peel, works well with the rest of my products.


This serum is AMAZING. When used in the evening it evens skin tone, helps to fade pigmentation and any small pimple scars. When used in the morning it provides a glowy, brightening effect which is a perfect base for make up. I was using a similar strength vitamin c serum before I switched to this but the squalene and hyaluronic acid in the Regena serum make it a game changer. I've even stopped using the separate hyaluronic acid serum I used before because I just don't need it anymore. Buy it: you won't regret it!

Cheryl Thomas

Very happy with product and delivery


This yellow cream serum really brights my skin within using a week. Love it!! Will keep using and try some other serums too!


Honestly the thing thats changed the game for my dry skin! Usually I'd just use a natural toner and a facial oil like rosehip oil, but after they absorbed dry patches would crop up again. With this i just put it on after toner and once its sunk in I spray some more toner over it to put sone water back into my skin, then put oil on. If my skin feels a bit dry and gross in the day I literally just splash some water over it and then pat dry with a towel and it rehydrates me face and makes it feel fresh again. Absolutely worth the money, was able to use a powder foundation with barely any dry patches showing up! Haven't used it for long enough to see any change in my complexion or evening out my skin tone but I'm very hopeful it'll help with that too
