The Benefits of Combining Collagen with Vitamin C

 

Slowing the ageing process is one of the key goals of skincare – but the underlying cause of ageing is often overlooked. Because changes in your skin aren’t defined by the date on your birth certificate, but rather by how much collagen your skin contains¹. From your mid-20s, collagen production declines by around 1% each year¹. And, as this slows, your skin loses structural support, which shows up as the first signs of ageing.

 

Below, we take a closer look at our Liftactiv collection combines collagen and vitamin C interact to support brighter, firmer, more structured-looking skin.

 

How does collagen support your skin?

 

Collagen is the most abundant protein in your body and forms the structural framework of your skin, helping maintain firmness and elasticity¹. Collagen sits within the dermis – the thick middle layer of your skin located between the outer epidermis and inner hypodermis – where it supports the skin’s shape and helps it withstand movement.

 

Your body produces collagen naturally, but this process slows with age. When this happens, support for the skin’s structure declines, which is when you start to see softer contours and fine lines¹. You can’t replace collagen by applying it to your skin, but you can support your collagen with other skincare ingredients that help your skin produce and maintain its levels.

 

What does vitamin C do for your skin?

 

Vitamin C (L-ascorbic acid) is an active ingredient, meaning it penetrates the skin to support internal processes, rather than remaining on the surface. It works as an antioxidant, helping neutralise free radicals (unstable molecules created by factors such as sun exposure and pollution that can interfere with normal skin processes and lead to visible damage)².

 

By limiting this damage (called “oxidative stress”), your skin can continue its natural renewal cycle without interruption. This helps prevent the build-up of damaged surface cells, so your complexion appears even and bright².

 

Why collagen and vitamin C work better together

 

So, can you use vitamin C with collagen? Yes – and in fact, they work best together³.

 

Vitamin C supports how your skin produces collagen and helps protect it once it’s formed². It supports the enzymes – proteins that drive key processes in your skin – that stabilise and strengthen collagen fibres. Without enough vitamin C, the collagen your skin produces isn’t as strong or effective³. At the same time, vitamin C helps reduce the oxidative stress that breaks collagen down².

 

Our Liftactiv 16% Vitamin C Serum delivers pure vitamin C for collagen production, alongside hyaluronic acid and glycerin to preserve the hydration levels needed for optimal skin function. Designed to deliver visible results with consistent use, skin appears 40% brighter and 51% more even, while fine lines look 17% less visible*. Formulated with just 11 carefully selected ingredients, it is suitable for all skin types, including sensitive skin.

5 key benefits of combining collagen with vitamin C

 

Collagen and vitamin C work together to support firmer-, brighter- and more resilient-looking skin. By helping maintain collagen levels while protecting against environmental stressors, this pairing delivers multiple anti-ageing advantages.

 

Read on to explore five vitamin C and collagen benefits.

 

1. Supports firmer-looking skin

 

Vitamin C helps your skin form stronger collagen fibres, allowing your skin to maintain its structure. As collagen support improves, your skin can appear firmer and more lifted, especially around the cheeks and jawline³.

 

2. Boosts radiance and brightness

 

Collagen and vitamin C help support your skin’s renewal cycle: clearing built-up surface cells so newer, clearer skin comes through – making your skin appear brighter and more even².

 

3. Prevents dark spots and uneven skin tone

 

Vitamin C slows tyrosinase, the enzyme that drives melanin production, helping limit excess pigment from forming in your skin². This prevents dark spots from deepening and becoming more noticeable.

 

4. Protects against environmental damage

 

Vitamin C can protect your skin from daily exposure to UV and pollution (both of which can lead to breakouts and uneven texture). By working to limit this environmental stress before it disrupts collagen production, vitamin C helps your skin maintain its structure and function².

 

5. Holds hydration for longer

 

Using vitamin C for collagen production helps support the skin structure that maintains your skin moisture barrier. By helping your skin retain hydration more effectively, vitamin C can leave the complexion feeling plumper, smoother, and more supple, while working to reduce dryness long-term.

 

How to use collagen and vitamin C in your routine

 

Vitamin C is one of the easiest ingredients to introduce into your routine because it is generally well-tolerated, and layers well with other skincare staples².

 

For example, incorporating vitamin C into a routine that also includes ingredients such as collagen peptides and hyaluronic acid can help your skin produce and maintain stronger collagen structures³. Read on to learn how to build a morning and evening routine with these collagen-supporting ingredients in mind, and which skincare products from Vichy can help.

 

Collagen and vitamin C: Morning routine

 

In the morning, vitamin C helps defend your existing collagen from daily oxidative stress.

 

Collagen loss is driven by ongoing damage as much as natural ageing, so pairing vitamin C with hydration and SPF helps maintain collagen integrity throughout the day.

 

Find your morning collagen and vitamin C routine below.

 

1. Cleanse your face: Use a cleanser to remove overnight oil, sweat, and skincare residue. Focus on a thorough but gentle cleanse so your skin is clear and ready to absorb the products and ingredients to follow.
2. Apply Liftactiv 16% Vitamin C Serum: Dispense four to five drops into your palm and press into your face and neck. This delivers a high concentration of pure vitamin C, which supports collagen while neutralising the free radicals that can break it down.
3. Smooth in Liftactiv Hyaluronic Acid Eye Cream for Anti Wrinkles: Apply a rice-grain amount across each under-eye using gentle circular motions. Enriched with vitamin C and caffeine, it helps hydrate, support collagen, and reduce the look of puffiness and fine lines.
4. Layer on Liftactiv Collagen Specialist 16 Day Cream: Apply a pea-sized amount to your face and neck. With peptides and vitamin C for collagen production, it supports skin structure while maintaining hydration levels.
5. Finish with SPF: Apply a broad-spectrum sunscreen at least 20 minutes before sun exposure.

 

Collagen and vitamin C: Evening routine

 

At night, your skin’s renewal cycle becomes more active. This creates an optimal window to use vitamin C for collagen production, as your skin is more receptive to ingredients while you sleep⁴.

 

Read on to explore your evening collagen and vitamin C routine.

 

1. Cleanse your face: Remove makeup, SPF, and daily buildup. If you’ve worn makeup or sunscreen, double cleanse – first with an oil-based cleanser to break down residue, followed by a water-based cleanser to clear the skin.
2. Apply Liftactiv Collagen Specialist 16 Bonding Serum: Dispense several drops into your palm and press gently into your skin, avoiding the eye area. This peptide-infused serum targets 16 visible signs of ageing³, including collagen decline.
3. Swipe on Liftactiv Hyaluronic Acid Eye Cream for Anti Wrinkles: Apply a pea-sized amount using light tapping motions. Vitamin C supports overnight skin cell renewal, helping reduce the appearance of puffiness by morning.
4. Finish with Hyaluronic Specialist H.A. Anti-Wrinkle Night Moisturiser: Massage a pea-sized amount into your face and neck. Formulated with hyaluronic acid and vitamin C, it helps maintain hydration while supporting collagen production overnight.
