    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.

Luv the ingredients in this product. Haven’t been using long enough to comment on the effectiveness but, so far so good.


The Regena 20% Vitamin C serum is great, it helped to clear my skin and make it smoother after just a couple of days from using it

I’m on my fourth purchase of this little bottle of magic. I’ve found that in my 30s my skin texture has changed and this has really improved it. It brightens and firms and is a very good base for makeup. I also find that it prevents spots and if one does appear it dries it out effectively. Love it : )

I could feel and see the difference after a week of using :)

So good for dark circles . You see a great difference very quickly

Debbie Mcgonigle

I absolutely love this product. My face feel so soft, and it's more radiant than before. My son has started using it to, and his spots are clearing up, giving a more even skin tone.


It’s a magic potion! I’ve recieved so many compliments on my complexion, my favourite is you’re “glowing” haha. I’ve converted my Mum and 2 friends so far. I will forever buy this product


Use this in the morning and then apply the day moisturiser skin feels refreshed and no break outs, my daughter's skin has improved too


Really good product. Helped clear my skin of acne scars gradually over a duration of 8-12 weeks. I saw improvements within the first weeks of treatment. Would definitely recommend to those who have a dark skin tone that is very blemish-prone and want to lighten your marks.

I'm on my 3rd bottle now. Love this serum


noticed a big difference since using this, has evened out my skin tone. Having oil skin it absorbs lovely into skin and doesn't feel heavy. Would definitely recommend


They are absolutely wicked. It didn't work for the first bottle but it does show slight difference. I am taking the 2nd bottle and I hope this freckles will fade away soon. I am very disappointed for the Regenacalm 2% Retinol and Vit C Serum. It didn't work at all. Too disappointed and I hope the second bottle its gonna works miracle.

This is amazing! The difference in my face was noticeable pretty much from day 1. My skin is brighter and patches have significantly reduced. This will be a go to favourite of mine from now on. I really love face theory products, a little goes a long way and so far I have been happy with everything I have tried. Looking forward to trying the rest of the range.

Sarah Young

I love this serum. My skin looks fresher, clearer and smoother. Scarring seems less noticeable. Excellent product.


I can never say definitively if a skincare product is working but I do think my skin looks a bit smoother. One definite bonus of this product is the nice mat, non-greasy finish. The price is great and the item arrived very quickly. I have no complaints.

Jorja Hardwick

This stuff is amazing! I've always suffered from problem skin and have to be really careful what I put on it, so was a little skeptical about using this. I didn't need to worry though as it really does what it says on the bottle! I feel it almost keeps my skin at bay and gives me a nice glow without looking like its sweat. I'm already on to my second bottle! Please do this product forever!

For me Regina all is best . This serum is not that good for me. Overall it’s ok.


The serum leaves my skin very soft and I think it is also helping with my hyoerpigmentation. Amazing costumer service is an added plus!


This is my second purchase of Vit C serum. I use it daily before moisturiser and Spf. It’s a wonderful lightweight consistency with a silky feel. It sinks in perfectly and defiantly gives me a glow. Am looking forward to purchasing the retinol version.


So good.after washing my face it looks so clear.

Tejal Patel

Excellent product. Really works well on pigmentation and problem areas. Makes skin smooth and soft.


I’m onto my second bottle of this now. I love how it makes my skin feel throughout the day, it’s softer than ever and prevents my skin from getting very oily. I’ll definitely keep on using this product

Faye James

I have pigmentation on my cheeks and I’ve really noticed a big difference. My skin texture is also very smooth and looks more even.


This is a lovely serum, you only need a small amount I use after cleansing & toning
