Vitamin C is one of the most powerful skincare ingredients available today — and for good reason. It brightens, firms, protects, and repairs the skin, making it a non-negotiable part of any serious skincare routine.
At Pt78 Skin and Body, we believe in results-driven skincare that combines nature and science. That’s why we proudly stock both our own Pt78 Highlight C Collagen Serum and a full range of SkinCeuticals Vitamin C products — the gold standard of clinical skincare.
In this guide, we’ll explore why Vitamin C is essential, what to look for in a serum, and how both Pt78 and SkinCeuticals lead the industry with formulations that transform dull, tired skin into radiant, healthy skin.
Why Vitamin C Matters for Skin Health
Vitamin C (ascorbic acid) is an antioxidant powerhouse. It helps neutralise free radicals — unstable molecules caused by UV exposure, pollution, and stress — that can damage the skin’s barrier and accelerate ageing.
Beyond its protective benefits, Vitamin C also:
Stimulates collagen production, improving firmness and elasticity.
Brightens uneven tone and fades pigmentation.
Reduces inflammation and redness.
Enhances sunscreen effectiveness when used in the morning.
It’s no wonder dermatologists call Vitamin C “the holy grail” of anti-ageing skincare.
What to Look for in a Vitamin C Serum
Not all Vitamin C products are created equal. When shopping for a high-quality serum, pay attention to three key factors:
1. Concentration – Look for 10–20% Vitamin C for maximum results without irritation.
2. Formulation Stability – L-ascorbic acid (the most potent form) is highly unstable; quality brands stabilise it with other antioxidants and the right pH balance.
3. Packaging – Vitamin C oxidises easily when exposed to light or air. Always choose dark, airtight bottles or tubes.
That’s where Pt78 and SkinCeuticals excel — both brands have perfected stability, potency, and skin compatibility.
The Clinical Benchmark: SkinCeuticals Vitamin C Serums
SkinCeuticals has earned global recognition as the leader in antioxidant science. Their Vitamin C serums are backed by over 40 peer-reviewed studies and trusted by dermatologists worldwide.
Here are the top performers available through our SkinCeuticals collection:
This cult-favourite serum combines 15% L-ascorbic acid, 1% Vitamin E, and 0.5% Ferulic Acid to deliver superior antioxidant protection. It brightens dull skin, smooths fine lines, and provides up to 72 hours of environmental defence.
Perfect for normal to dry skin types, it leaves the skin feeling radiant and supple.
Ideal for oily or combination skin, this advanced antioxidant blend includes Phloretin, Vitamin C, and Ferulic Acid to even skin tone and reduce discolouration. It’s lightweight, fast-absorbing, and perfect under makeup or SPF.
This breakthrough formula targets blemish-prone and oily skin. Infused with Silymarin (milk thistle extract) and Salicylic Acid, it refines pores while preventing oxidation of sebum — a leading cause of breakouts.
While not a pure Vitamin C formula, this serum works overnight to strengthen skin with antioxidants like Resveratrol and Baicalin, complementing your morning Vitamin C routine for 24-hour protection.
Natural Radiance: Pt78 Highlight C Collagen Serum
When it comes to natural skincare in Australia, Pt78 Skin and Body stands out for combining high-performance actives with organic botanicals.
The Highlight C Collagen Serum delivers 15% Vitamin C in a lightweight, vegan-friendly formula enriched with Davidson Plum, Kakadu Plum, and Sodium Phytate. These native Australian extracts are rich in antioxidants and fruit acids, which enhance skin luminosity and boost collagen naturally.
It’s perfect for:
Sensitive or reactive skin types.
Those seeking a natural yet potent brightening solution.
Layering under moisturiser or SPF for daily protection.
Highlight C leaves the skin visibly smoother and brighter, without the tingling or irritation sometimes caused by high-strength Vitamin C products.
How to Use Vitamin C Effectively
To get the most from your Vitamin C serum:
Use it in the morning. Apply after cleansing and toning, but before moisturiser and sunscreen.
Apply 3–5 drops. Gently press into the skin (don’t rub) for better absorption.
Follow with SPF. Vitamin C boosts sunscreen performance, but doesn’t replace it.
Store properly. Keep in a cool, dark place to prevent oxidation.
For an optimal anti-ageing routine:
Morning: Cleanse → C E Ferulic → Moisturiser → Ultra Facial Defense SPF 50
Evening: Cleanse → Refine A Retinol Serum → Triple Lipid Restore 2:4:2
Can You Combine Pt78 and SkinCeuticals?
Absolutely — and doing so can give you the best of both worlds. Many clients pair SkinCeuticals C E Ferulic in the morning with Pt78 Refine A at night for a balanced blend of clinical precision and natural repair.
Because both brands focus on ingredient purity and proven performance, they complement each other perfectly.
