Facetheory – Regena C20 Serum (good but could be better)

Regena C20 Serum
Regena C20 Serum


It really is no secret that I am a bit of a vitamin c addict, to feed my addiction step in the Regena C20 Serum. There is something about the brightening and sunscreen boosting effect that leaves me wanting more. (There’s an opening to a love letter if I have ever seen one!)

However, there is one BIG problem with vitamin c serums, there are lots of different varieties, and the purest form (ascorbic acid) has a habit of going bad very quickly. You can generally mitigate this by keeping the serum in the fridge, which seems to help slow down the oxidation process. I was looking for something a little less high maintenance, so sought one of the vitamin c derivatives, in this case, sodium ascorbyl phosphate. Looking at the product claims that were on offer from the Regena C20 Serum, it seemed to be the answer to my prayers!

This serum was really a good reason why you need to test products for a while before making a final judgement. Initially, I was not too fond of the Regena C20 Serum, but then grew to like it – read on to find out why.

Regena C20 Serum product claims and ingredients

The serum uses a stable derivative of vitamin c, which will not oxidise after opening, which helps with the longevity of the product. Facetheory claim that Sodium ascorbyl phosphate is just as effective as l-ascorbic acid and is packaged in a brown bottle to protect the serum from UV light. So while the serum is unlikely to oxidise it would appear can be vulnerable to UV light, so it is probably best stored in a dark area or cabinet.

The Regena C20 serum comes with the usual claims of vitamin C, namely: help to increase firmness, evening out skin tone, brightening dull skin, reduction of age spots. Facetheory also states that this serum can significantly reduce acne bacteria, which is a big plus for acne-prone skin types.

As with most Facetheory products they are vegan, paraben-free, no silicones, polyethylene glycols (PEGS) or mineral oils and not tested on animals and is made in the UK.

The main active ingredients include:

  • Aloe vera – a time tested additive to aid with soothing.
  • Dill extract – to help stimulate the generation of elastin – this protein helps the skin retain the elasticity of the skin and prevents the skin from hanging, elastin production slows down with age.
  • Ferulic acid – it is an antioxidant that helps protect against free radicals. This acid is also commonly used in vitamin c formulas as it can help to stabilise the vitamin c.
  • Hyaluronic acid – it is a popular ingredient which acts helps to draw moisture to the skin (i.e. a humectant). Some believe that this can help the absorption of products to the skin.
  • Liquorice extract – used to help reduce hyperpigmentation and helps to reduce acne-causing bacteria.
  • Panthenol (vitamin B5) – this is another humectant and helps to reduce the itching sensation you can experience with vitamin c formulas.
  • Sodium ascorbyl phosphate – a stabilised derivative of vitamin c.
  • Vitamin E – a powerful antioxidant and used to help with reducing signs of inflammation and ageing. Vitamin E and C work together like a dream and are complementary.

My final thoughts

Facetheory Regina C20 Serum Spread

Left-hand side serum directly from the bottle, middle lightly smeared, and right rubbed in. (Excuse my dry hand!)

Where to start with this one? I was not too fond of this when I first started to use it, but it eventually grew on me.

First off, the smell of the Regena C20 serum is really quite horrendous. It has a strange metallic smell and almost smells a bit spoiled. In normal circumstances, this would indicate the product has gone off, after some research, it turns out that is how it is supposed to smell. I really don’t appreciate additives in cosmetics to improve the scent, but in this case, I think that I would welcome it! Sadly the smell lingers for some time, regardless of what is layered before or after it.

The Regena C20 serum is a formula that you need to use sparingly, I think that 2-3 drops are enough to do your whole face. Use more, and you end up looking like a greasy mess! I would say that this is not a cosmetically elegant formula, in my opinion, this might have something to do with the squalene (a well-known emollient) which may prevent the serum from fully sinking in.

The reason I initially hated this serum was that I was using too much, and it would just sit on top of my skin, and anything else would not absorb. However, after limiting the amount of Regena C20 serum I used, I was happy with the effect.

I feel that this did a good job at brightening and fading, and I ended up liking it. I also found that this serum did not aggravate my acne-prone skin.

If you are interested in this serum, this can be purchased from the Facetheory website for £18.99 which lasts about 2 months, depending on how many times a day you use it (I use it in the mornings only).

I would purchase this again (hopefully they will sort out the scent!)
