The Ultimate Guide to Vitamin C Serum in Skincare: Benefits, Usage & What To Look For Before Buying

If you’re looking for radiant, glowing skin, there’s one powerhouse ingredient you need in your skincare routine: Vitamin C. 
Known for its brightening, anti-ageing, and skin-protecting benefits, Vitamin C serum is a must-have for anyone starting their super natural skincare journey. But what makes this wonder ingredient so special, and how should you be using it for the best results? 
Read on as we break down everything you need to know about Vitamin C serum—including why a hybrid formula like UKLASH Vitamin C Serum with Hyaluronic Acid is your best bet for hydrated, luminous skin.

What Does Vitamin C Serum Do for Your Skin?

Vitamin C is a powerful antioxidant that works wonders for your complexion. Here’s why it deserves a prime spot in your skincare routine:
✔ Brightens Skin Tone – Vitamin C restricts melanin production, helping to fade dark spots and hyperpigmentation, leaving you with an even, glowing complexion.
✔ Boosts Collagen Production – Collagen keeps skin firm and youthful. Vitamin C stimulates collagen production, reducing the appearance of fine lines and wrinkles.
✔ Fights Environmental Damage – Pollution, UV rays, and other environmental aggressors can speed up skin ageing. Vitamin C is famed for neutralising free radicals and protecting your skin from premature ageing.
✔ Enhances Sun Protection – While it’s not a replacement for SPF, Vitamin C can work alongside your sunscreen to enhance protection against sun damage.
✔ Evens Out Texture – Regular use of Vitamin C can improve skin texture, making it feel smoother, plumper, and more refined.

How to Use Vitamin C Serum for Maximum Results

To get the most out of your Vitamin C serum, follow these simple steps:

1. Apply on Clean Skin – After cleansing with the UKLASH Micellar Water or using the soothing Hydra-Gel Eye Patches, apply a few drops of the UKSKIN by UKLASH Vitamin C+HA Eye Serum to dry skin. This helps the serum penetrate deeply for maximum effectiveness.
2. Use in the Morning – Vitamin C is best applied in the morning to protect your skin from environmental stressors throughout the day.
3. Follow with Moisturiser & SPF – Lock in hydration with a moisturiser, and always finish with SPF 30+ to shield your skin from UV damage.
4. Pair with Complementary Ingredients – To avoid irritation, don’t mix Vitamin C with retinol or benzoyl peroxide. However, it pairs beautifully with Hyaluronic Acid, as in our Vitamin C+HA Eye Serum for added hydration (more on that below!).

What to Look for When Buying a Vitamin C Serum

Not all Vitamin C serums are created equal! Here’s what to consider when shopping for the perfect one:

✔ Stable Form of Vitamin C – Unstable forms of Vitamin C can often cause irritation, don’t have a long shelf life and don’t interact well with other skincare products. Look for a stabilised form of Vitamin C for a gentler experience, especially if you’re new to the ingredient, with all the added benefits and long shelf life!
✔ Added Hydrating Ingredients – Pure Vitamin C can sometimes be drying, so look for a formula with Hyaluronic Acid, like our Vitamin C+HA Eye Serum, to maintain moisture levels.
✔ Free from Irritants – Avoid serums with artificial fragrances or unnecessary fillers that can cause sensitivity.
✔ Air-Tight Packaging – Vitamin C degrades when exposed to air and light, so opt for a serum in a dark glass, air-tight bottle to maintain potency.

FAQs About Vitamin C+HA Eye Serum

Is Vitamin C irritating?

In high percentages, it can cause irritation for those with sensitive skin, which is why we’ve used a stabilised derivative in our serum instead! This brings the benefits of brightening and reducing pigmentation without the harsh effects that come along with pure Vitamin C.

Is this serum suitable for all skin types?

This serum is best suited to those with oily, normal or combination skin types but can also be introduced to other skin types, starting on a once-weekly basis and slowly building up a tolerance.

How do I incorporate the serum into my daily routine?

We recommend applying it in the morning after cleansing your face and following up with your favourite SPF to boost your defence against harmful pollutants and UV rays. 

How long will it take to see results?

We recommend using once a day for around four to six weeks before looking to see visible results.

Does the serum work as sun protection?

Vitamin C is an ingredient which is known to boost the effectiveness of an SPF when layered underneath, which is why we recommend applying the serum before following up with your favourite SPF to help in defending your under-eye area from harmful UV rays and pollutants.
