Why is Vitamin C Essential for Your Skin?

Powerful Antioxidant Protection

Vitamin C is an essential superhero ingredient that fights free radicals and strengthens the skin. Free radicals are unstable molecules that can cause premature skin ageing such as fine lines, wrinkles, loss of elasticity and pigmentation. Vitamin C in serum form is incredibly effective at neutralising free radicals thanks to its antioxidant properties, providing an invisible shield of protection against premature skin ageing.

Collagen Boosting Benefits

As we age, collagen production naturally decreases from our early 20’s onwards, leading to line formation and of skin sagging. The beauty of Vitamin C and a serum is that it can help stimulate collagen synthesis to promote a more firm and bouncy complexion.

Brightening and Even Skin Tone

Vitamin C is a tyrosinase inhibitor, meaning it can reduce the production of melanin, which helps prevent dark spots and hyperpigmentation. The best Vitamin C serum for hyperpigmentation will not only suppress the formation of dark spots, but will also help create a more unified skin tone and clarified complexion. It’s one of the best brightening skincare ingredients for glowing skin.

How to Choose the Best Vitamin C Serum Australia Has to Offer

There are countless Vitamin C serums down every beauty isle, but the potency and use of high-quality stable ingredients is key. Some formulations may oxidise and leave you disappointed. When selecting the best Vitamin C serum Australia has available, there are a few factors to be mindful of.

Key Ingredients to Look for in Vitamin C Serums

1. L-Ascorbic Acid: This is the most potent form of Vitamin C, known for its ability to penetrate deeply down to the dermis to deliver results. However, L-Ascorbic acid can be unstable, so make sure the serum is stored in an airtight, amber glass container. Alternatively, seek an encapsulated Vitamin C formulation to ensure the pure potency actually reaches your skin before oxidising.
2. Ferulic Acid: The addition of this antioxidant helps to stabilise Vitamin C, also enhancing its effectiveness and longevity. Many of the best Vitamin C serums contain ferulic acid for amplified protection against environmental stressors and a great choice for dry skin.
3. Vitamin E: Quite often, you’ll spot Vitamin E paired with Vitamin C in formulation. This is because Vitamin E boosts its antioxidant properties by about eight times and helps protect the skin from oxidative stress, potentially making it the right antioxidant for you especially is you have dry skin.

How to Use Vitamin C Serums for Maximum Effectiveness

The Right Application Routine

To get the most out of your Vitamin C in serum, gently press a few drops of the serum to your face and neck immediately after cleansing. From here, layer your preferred moisturiser, sunscreen and makeup if desired. Some skin types can experience mild sensitivity to the sun when using Vitamin C, so ensure daily SPF application isn’t overlooked.

Start Slowly

Like with all active ingredients, it's essential to gradually introduce the Vitamin C to your skincare routine. Start by applying your serum every second morning, slowly increasing the frequency as comfortable. This will reduce the chance of irritation, for sensitive skin in particular.

Combine with Other Actives

Vitamin C works very well with other skincare ingredients like Niacinamide, Hyaluronic acid and Peptides. We recommend avoiding the use of Vitamin C at the same time as strong exfoliating acids (like AHAs and BHAs) and even retinol products, to prevent skin irritation.
