The serum contains 15% L-ascorbic acid, which is a potent form of vitamin C. Vitamin C is a powerful antioxidant that helps protect the skin from damaging free radicals, which can cause premature aging. It also helps brighten the skin and improve its overall texture.

It helps to protect the skin from damage caused by free radicals and strengthens the skin’s moisture barrier so the skin looks plump and hydrated.

Truth Serum by Ole Henriksen is like popping a daily multivitamin for your face.

From the get-go, Ole Henriksen has been a staunch believer in the power of vitamin C. The serum contains a combination of sodium ascorbyl phosphate (SAP) and calcium ascorbate. Some experts say this is a more stable form of vitamin C compared to L-ascorbic acid.

While the percentage isn’t indicated, it’s quite low, making this the best serum to buy if you have sensitive skin or aren’t sure if your skin will tolerate it.

The serum also contains collagen, orange and green tea extracts, and aloe juice. This will calm down hyperpigmentation and boost skin elasticity. It contains hydrating ingredients and stimulates the production of collagen, leaving you with smoother and more radiant skin.

The Ole Henriksen serum has a refreshing citrus scent that makes putting it on the face a real treat. It comes in a slightly opaque glass bottle with a pump for easy dispensing. Application is a breeze and there are no pesky waiting periods.

A disadvantage of this serum is the form of vitamin C it uses. Derivatives are less powerful than L-ascorbic acid but if the goal is to avoid irritation and slowly build up a tolerance, it’s a great starter product. I also wish they disclosed the exact concentration of vitamin C in the serum but it’s still an effective product, nonetheless.


  • Contains a vitamin C derivative that is said to be more stable than pure vitamin C
  • Has a low vitamin C percentage, good for sensitive skin
  • Contains collage, orange and green tea extracts and aloe juice
  • Fades dark spots and improves elasticity
  • Comes in a semi-opaque bottle with a pump

Say hello to brighter days with the Drunk Elephant C-Firma Day Serum! Yes, you read that right–this is a vitamin C serum for daytime use. While I preach about using your restorative and active ingredients at night, vitamin C is actually best used during the day. It supports sunscreen and amplifies its protective benefits. This vitamin C serum helps block UV exposure and fend off pollutants and free radicals.

The main ingredient is 15 per cent L-ascorbic acid, which is an anti-ageing workhorse. It brightens, firms and protects the skin. Working together with vitamin C is pumpkin ferment and pomegranate extract, which refine pores and slough off dead skin cells so you get a more even skin tone.

Drunk Elephant also added Indian gooseberry to reduce the signs of ageing caused by stress (a skincare benefit we all need nowadays). The Day Serum is as much of a corrective brightener as it is a preventive vitamin c serum.

The effects last 72 hours after you apply it. It’s like a tonic for the face because it visibly wakes up a tired-looking face while preventing lines and wrinkles.

The Drunk Elephant C-Firma Day Serum is stored in the cutest of bottles. The packaging is functional, too, since it’s tightly sealed to keep the serum from oxidizing.

In terms of texture, it’s a lightweight oil-type serum. It does feel a bit sticky at first but that fades away the more you work it into your face.

While this isn’t as pricey as the SkinCeuticals C E Ferulic Serum, it’s still quite a steep investment. You should also take note that this serum has a divisive scent. It doesn’t smell like a fragrant or perfumey serum so it might irritate a sensitive nose.


  • Contains 15 per cent L-ascorbic acid, pumpkin ferment, pomegranate extract and Indian gooseberry
  • Brightens the complexion and fights the signs of ageing
  • Retexturizes the skin and dissolves dead skin cells
  • Effects last for 72 hours
  • Sealed in an airtight bottle

Alpha-H has formulated of the best Vitamin C serums for those with sensitive skin.

It’s made in Australia and is vegan and cruelty-free. The Alpha-H serum contains ethyl ascorbic acid. Supporting it are liquorice extract, hyaluronic acid and grape seed extract. This antioxidant blend boosts skin radiance, increases elasticity and protects the skin from oxidative damage.

The ethyl ascorbic acid stimulates collagen production so skin looks more youthful and smooth. Liquorice reduces the formation of melanin and grape seed extract boosts the serum’s antioxidant effects.

Hyaluronic acid draws water into the skin and minimizes potential irritation caused by vitamin C. Your skin will look firmer and the appearance of pores will be minimized.

The serum is very easy to use and absorbs quickly into the skin. It leaves a velvety feeling after application and makeup sits on top of the serum quite well since the formula is water-based.

The serum is stored in a beautiful neutral-coloured dropper bottle that shields it from light and oxygen exposure. It’s a great lightweight serum that’s gentle enough for those with sensitive skin.


  • An Australia-made serum that’s cruelty-free and vegan
  • Contains ethyl ascorbic acid, liquorice extract, hyaluronic acid and grape seed extract
  • Improves the complexion and increases skin elasticity
  • Prevents oxidative damage and stimulates the production of collagen

A Vitamin C Serum Buying Guide: All You Need to Know

What is vitamin C?

Ascorbic acid or vitamin C is a powerful, acidic antioxidant that stimulates the skin to regenerate and heal itself. It fades hyperpigmentation and soothes inflammation. It also defends the skin from harmful free radicals and boosts collagen.

You’ll often see this power ingredient infused in serums, moisturisers, cleansers and even in powder form. It’s adaptable enough to be worked into different formulas and concentrations. The most effective topical form of vitamin C, though, is called L-Ascorbic acid.

Why should you use a vitamin C serum?

Vitamin C in skincare isn’t a new thing actually but it has gained popularity, especially with a renewed interest in all things skin and beauty. It’s as much of a skin anti-ageing product as it is a complexion-enhancing ingredient.

Vitamin C helps boost vitamin E production. These 2 vitamins protect the skin from photo-ageing caused by free radicals and sun exposure. It stimulates the skin to produce collagen and resurface the outer layers. In a sense, it is an exfoliant because it encourages faster cell turnover. Dark spots become fainter, as a result. That’s why it gives users a much sought after glow.

Vitamin C also preserves the skin’s collagen reserves, resulting in a more refined skin texture and a reduction in the signs of ageing. With every use, your skin will look plumper and firmer. It’s like turning back the clock.

Who should use vitamin C serums?

Vitamin C covers a wide range of skincare concerns so all skin types from sensitive to acne-prone skin can benefit from it. It can be used as a preventative measure for young people, while for people concerned about ageing, it can treat fine lines and wrinkles.

It is particularly beneficial for people struggling with hyperpigmentation and a dull complexion. Skin that has started showing signs of sun damage will also drink up the effects of a vitamin C serum.

Is it safe to use?

Given its potency, it needs to be introduced slowly into your skincare routine, especially if you have sensitive skin.

The devil is in the details so the thing you should pay attention to is the concentration of vitamin C in a formula.

For sensitive skin types, it’s recommended to start with a baseline of 5 per cent before working your way up. A derivative (meaning something that’s diluted or a non-pure version) or a gentler form of vitamin C like vitamin C ester, could be a good introduction to the product.

Of course, the higher the dose, the better the results will be. If your skin is quite resilient, you could use a serum with between 10 to 20 per cent vitamin C. Definitely start slow and build up your tolerance. Patch test a product to see if there are any adverse reactions.

How To Choose a Vitamin C Serum


Firstly, you will want to look out for L-ascorbic acid (pure vitamin C). It’s the most effective form of vitamin C, which is also why it’s the most well-known.

Ideally, L-ascorbic acid should be in the first 5 ingredients on the serum (The order of the ingredients on the label gives you an indication of the percentage of ingredients used).


Most skin types can tolerate vitamin C serums at a 10 to 20 per cent.

Those with sensitive skin may want to start with a 10 per cent concentration or lower. If you’re the type of person who likes to go hard on their skincare, keep in mind that a 20% concentration will not necessarily mean more efficacy and has the potential to irritate your skin.

Supporting Ingredients

Look out for a Vitamin C formulated with ferulic acid and vitamin E. These ingredients enhance the effects of vitamin C.

Vitamin E is an antioxidant that stabilises vitamin C and fortifies the skin barrier. While ferulic acid, helps lower the pH level of the ingredient meaning your skin can better absorb it.

Another ingredient that supports or complements vitamin C is hyaluronic acid known for its hydrating properties, which draws water into the skin and prevents moisture loss. It has soothing effects which can act as a buffer to the irritating properties of vitamin C.


Vitamin C should not be exposed to light because light makes the actives unstable. Air and heat exposure also degrades vitamin C.

When preserved in serum form, it should come as a clear liquid. It should be stored in a dark bottle to minimise light exposure. The opening should be airtight.

Dropper bottles and air pumps are good carriers for vitamin C. Just remember to store the bottle in a cool and dark place to prolong its life further.
