This 5% vitamin C complex visibly brightens and illuminates your skin with its antioxidant packed formula, to tackle hyperpigmentation and smooth fine lines.

This next-generation vitamin C formulation brightens skin while protecting it from environmental aggressors. The lightweight yet nourishing formula helps to even skin tone and texture and smoothens fine lines.  It is supported by other key ingredients such as ferulic acid to boost the effectiveness of the vitamin C, along with niacinamide for brightening and vitamin E for for soothing and hydrating

Why use a complex?

Pure ascorbic acid is known to be unstable & highly susceptible to oxidation via heat, light, air & water. This means using more stable derivatives of vitamin C in our products ensures less discolouration and a longer shelf life. These more stable forms also oxidise at slower rates within the product, and therefore are more available to the skin, to deliver all that vitamin C has to offer.

How it works:

5% vitamin C complex: An innovative complex of 3 stabilised forms of vitamin C to ensure a more stable and effective brightening formula.

Ferulic acid: A versatile antioxidant that boosts effectiveness of vitamin C.

Vitamin E: Rich in antioxidants known to help support skin and provide hydration.

Niacinamide: Helps to even skin tone and diminishes pore size.

How to use
Step 2 of your skincare routine – treat

Can be used daily in the AM and PM

Massage 1-2 pumps onto cleansed skin.

For best results, use as part of a full Vitamin C Fix routine:

Step 1: Cleanse using the Vitamin C Fix Cleanser
Step 2: Follow with the Vitamin C Fix Brightening Pads
Step 3: Apply the Vitamin C Fix Eye Cream 10%
Step 4: Use 1-2 pumps of the Vitamin C Fix Serum 5%
Step 5: Finish with the Vitamin C Fix Hybrid Gel Cream

If you are going to layer this serum over a concentrate, we recommend our Hyaluronic Fix Extreme4 Concentrate which deeply hydrates the skin. This combination is perfect for those with sensitive skin, or those new to vitamin C, as it minimises the chances of irritation.

Using vitamin C and retinol together is a powerful way to reduce fine lines and wrinkles, we don’t recommend using them together in the same routine, so stick to one in the morning and the other at night; use the Vitamin C Fix Serum in your AM routine and the Retinol Fix Serum in the PM.

Use SPF the morning after – we recommend our Illuminating SPF 30 as the final step in your routine. This SPF was specifically designed to protect and illuminate skin after using Vitamin C Fix

The Science

Ascorbic acid – vitamin C's purest form – is hard to stabilise in an effective formula: when it comes into contact with heat, light, air and water, it starts to oxidise and form dehydroascorbic acid, which is not the active form of the molecule, meaning potency and antioxidant abilities have been compromised. Our upgraded complex stabilises the formula, slowing the oxidation rate right down and making it less likely to destruct. It means we’ve been able to deliver a higher concentration of vitamin C without compromising stability and effectiveness. The higher concentration of vitamin C means that you’ll see brighter, more even-toned skin than ever before, and the stable formula means it’s long-lasting, both in terms of efficacy on skin and shelf-life duration.

Why you need it

Our next generation Vitamin C formula tackles multiple skin concerns in one bottle. Whether you're looking to even out your skin tone, fade marks or reduce signs of ageing, do it all while keeping your skin hydrated and plump with this high performance serum.

The 5% Vitamin C Complex

  • Stay-C® 50

    Has a proven conversion into ascorbic acid - vitamin C's purest form - once it has penetrated the skin's surface and is the only derivative with a use level of up to 15%.

  • L-VCG

    Is metabolised into ascorbic acid more gradually on contact with the skin compared to other derivatives, giving it a unique time-released effect - you'll experience the benefits for longer.

  • Specwhite VCE

    An ethered derivative, meaning it is both hydrophilic (water-loving) and lipophilic (oil-loving), which results in better skin penetration compared to ascorbic acid.

5% complex

Potent, next-generation 5% complex with three stabilised forms of vitamin C, each with its own supercharged benefit.

Stabilised formula

Stabilised formula means less chance of oxidisation, which affects vitamin C's impact on skin. Our upgraded formula means a better concentration of vitamin C that doesn't compromise stability or effectiveness.

Brighter skin

Skin is left brighter and more even toned than ever before, with fine lines smoothened for a glowing, youthful complexion, We believe these results rival more expensive formulas.
