The Advantages of Vitamin C for Skin, and the Skincare Combinations That Work Best

Vitamin C has earned its place as one of the most researched and widely recommended ingredients in skincare. From dermatologists to formulation experts, it is consistently cited for its ability to support brighter, healthier-looking skin when used correctly.

But while vitamin C is often talked about as a miracle ingredient, understanding how it works and what it should be paired with is what makes the real difference.

Here is a clear, evidence-led look at the advantages of vitamin C for skin, and the skincare combinations that help it perform at its best.

Why Vitamin C Matters in Skincare

Vitamin C, also known as ascorbic acid or its derivatives, is a powerful antioxidant. In skincare, antioxidants help protect the skin from environmental stressors such as pollution and UV exposure, which are known to accelerate skin ageing.

When applied topically, vitamin C works at the surface and deeper layers of the skin to support tone, texture and overall clarity.

The Key Benefits of Vitamin C for Skin

Brighter, More Even Skin Tone 
Vitamin C helps inhibit excess melanin production, which can reduce the appearance of dark spots, pigmentation and uneven skin tone over time.

Supports Collagen Production 
Vitamin C plays a direct role in collagen synthesis, helping to support skin elasticity and reduce the appearance of fine lines.

Antioxidant Protection 
Vitamin C neutralises free radicals caused by pollution and UV exposure, helping protect the skin barrier.

Improves Skin Texture 
Regular use of vitamin C skincare can help smooth uneven texture and support a healthier-looking complexion.

How to Use Vitamin C in Your Skincare Routine

Vitamin C is most effective when used in the morning, after cleansing and before moisturiser and SPF.

The Bottom Line
