Vitamin C vs Hyaluronic Acid: Which One Does Your Skin Need?
Standing in front of a shelf of serums, or scrolling through option after option online, it is easy to end up more confused than when you started. Vitamin C and hyaluronic acid are two of the most talked about ingredients in skincare right now, and it is tempting to assume you need to choose between them. The truth is simpler than the marketing suggests. These two ingredients are not competing for the same job, they are built for different ones. Once you understand what each actually does, choosing becomes far less complicated, and browsing Maggs London’s skincare range becomes a lot less overwhelming too.
What Vitamin C Actually Does For Your Skin
Vitamin C is best known as an antioxidant. It works by helping to neutralise the free radicals your skin comes into contact with daily, from pollution to UV exposure, both of which can contribute to a dull, tired looking complexion over time. Many people reach for vitamin C to help with uneven tone, dullness or the visible effects of sun exposure, since it supports the skin’s natural brightness with consistent use. According to the Cleveland Clinic, there is good scientific evidence that vitamin C’s antioxidant effects can reduce cell damage and improve how skin looks over time. It is typically applied in the morning, underneath sunscreen, so it can help support your skin’s defences throughout the day.
What Hyaluronic Acid Actually Does For Your Skin
Hyaluronic acid works on a different problem altogether. It is a humectant, meaning its role is to attract and hold onto water within the skin, which is why it is so closely associated with hydration. The Cleveland Clinic notes it can hold many times its own weight in water, which is what makes it so effective at helping skin look plumper and feel smoother. Unlike vitamin C, hyaluronic acid rarely causes irritation, making it one of the more forgiving ingredients to introduce and generally suitable across most skin types, including sensitive skin. It is usually used both morning and evening, applied to slightly damp skin so it has moisture nearby to draw from.
Which One Your Skin Is Actually Asking For
If your main concern is dullness, dark spots or the early signs of sun damage, vitamin C is likely to be more relevant to you right now. If your skin feels tight, dry or rough, particularly after cleansing, hyaluronic acid is probably the ingredient doing the heavier lifting. Plenty of people find they need both, just for different reasons. It is entirely possible to have skin that looks a little uneven in tone while also feeling dehydrated, especially through colder months or after long days indoors with the heating on. In cases like this, vitamin C and hyaluronic acid work well layered together rather than swapped for one another, since one is addressing tone and protection while the other is addressing moisture. Our guide to 5 Skincare Habits That Help You Look Younger covers how hydration fits into a wider routine, if you want to build on this further.
| Vitamin C | Hyaluronic Acid | |
|---|---|---|
| Main benefit | Antioxidant support, brighter tone | Deep hydration, plumper skin |
| Typical use | Once daily, usually in the morning | Once or twice daily |
| Skin concern it targets | Dullness, uneven tone, sun damage | Dryness, tightness, dehydration lines |
| Where it sits in your routine | After cleansing, before SPF | After cleansing, before moisturiser |
Introducing Vitamin C Without Irritating Your Skin
Vitamin C can cause mild tingling or redness for some people, particularly at higher concentrations, so it is worth introducing gradually rather than using it daily from the start. Beginning two to three times a week and building up as your skin adjusts tends to work better than diving straight into daily use. Choosing a well formulated serum, ideally in a dark or airtight bottle since vitamin C can lose potency when exposed to light and air, will help it stay effective for longer. Because vitamin C can leave skin slightly more sensitive to the sun, applying a broad spectrum SPF over the top every morning is not optional, it is part of what allows the ingredient to work safely in the first place.
So, Which One Should You Reach For First?
Rather than treating this as a choice between two rival products, it helps to think of vitamin C and hyaluronic acid as solving different problems. Start with whichever addresses what is bothering you most right now, whether that is dullness or dehydration, and there is nothing stopping you introducing the other once your skin has settled. Used well, the two tend to complement each other rather than compete.
