Every day, your skin battles invisible enemies — UV radiation, pollution, and oxidative stress. These environmental aggressors accelerate ageing, trigger inflammation, and weaken your skin barrier. The result? Dullness, fine lines, pigmentation, and loss of elasticity.
The solution lies in antioxidant skincare, particularly Vitamin C, one of the most researched and effective ingredients in dermatology. At Pt78 Skin and Body, we combine clean Australian-made formulations with advanced SkinCeuticals antioxidant serums to help protect, repair, and brighten skin under Australian conditions — where sun exposure and air pollution are at their peak.
Understanding Oxidative Stress
When UV light and pollution interact with skin cells, they generate free radicals — unstable molecules that damage DNA, proteins, and lipids. This process, called oxidative stress, is the primary driver of premature ageing.
Antioxidants like Vitamin C, Vitamin E, and Ferulic Acid neutralise these free radicals, shielding your skin from cellular breakdown. They also enhance sunscreen performance, making antioxidants an essential part of every daytime routine.
Why Vitamin C Is Essential for Radiant Skin
Vitamin C is one of the most powerful topical antioxidants available. It:
Brightens dull skin and fades pigmentation.
Stimulates collagen synthesis, improving firmness.
Protects against UV-induced oxidative stress.
Enhances your skin’s natural healing response.
However, not all Vitamin C serums are created equal. Stability, concentration, and formulation determine effectiveness. That’s why SkinCeuticals is globally recognised for creating the gold-standard antioxidant formulas dermatologists trust.
The SkinCeuticals Vitamin C Difference
SkinCeuticals C E Ferulic Vitamin C Serum is the benchmark for antioxidant protection. It combines 15 % pure L-ascorbic acid (Vitamin C), 1 % Vitamin E, and 0.5 % Ferulic Acid — a patented triple-antioxidant blend proven to deliver 8× environmental protection against free-radical damage.
Other standouts include:
SkinCeuticals Phloretin CF — Ideal for normal-to-oily skin, brightening dull tone and refining texture.
SkinCeuticals Silymarin CF — Combines Vitamin C with Salicylic Acid to reduce oil and prevent breakouts.
SkinCeuticals AOX Eye Gel — A lightweight antioxidant gel that targets under-eye puffiness and fine lines.
These formulations penetrate deeply, working within the skin for long-lasting protection against UV, pollution, and blue-light exposure.
A Natural, Vegan Alternative: Pt78 Highlight C
For those who prefer a clean, plant-based approach, Pt78 Highlight C 15 % Vitamin C Serum offers powerful antioxidant protection using naturally derived actives.
This lightweight, Australian-made serum features:
Kakadu Plum — the world’s richest natural source of Vitamin C.
Davidson Plum — packed with antioxidants to neutralise oxidative stress.
Sodium Ascorbyl Phosphate — a stable form of Vitamin C that promotes collagen renewal.
Highlight C supports radiance and firmness while being vegan, cruelty-free, and made in Australia — perfect for those seeking effective, ethical skincare.

Beyond Vitamin C: Building an Antioxidant Shield
While Vitamin C takes centre stage, combining it with other antioxidants enhances its effectiveness.
Vitamin E protects skin lipids and strengthens barrier resilience.
Ferulic Acid stabilises Vitamin C and amplifies protection.
Niacinamide (B3) supports repair and reduces inflammation.
Plant extracts like Kakadu Plum and Green Tea deliver a natural antioxidant boost.
Together, these actives create a multi-layered shield that defends against daily environmental assaults while restoring skin’s radiance.
The Bottom Line
Antioxidants are the cornerstone of any modern skincare routine, especially for Australians exposed to high UV and pollution levels. Vitamin C isn’t just a brightening ingredient — it’s your skin’s daily defence system.
