High-Potency Vitamin C Serum
Power-Up C Serum 25% Active Vitamin C
25% Active Vitamin C
Not all Vitamin C is equal — especially for skin over 45. This formula uses a stable, oil-soluble Vitamin C (Isopalmitate) paired with Kakadu Plum, peptides and antioxidant-rich Australian botanicals. No irritation. No oxidation. Just results.
From Founder Vanessa Jilly, 35 Year Global Skincare Educator
"L-ascorbic acid is brilliant in your 20s and 30s. After 45, the pH it needs to work becomes the very thing that irritates your skin. This serum was formulated with that in mind."
Why most Vitamin C fails after 45
Your serum might be the problem — not your skin.
Most mass-market Vitamin C serums use L-ascorbic acid. It's potent, but it needs a very low pH to penetrate skin. After 45, your skin barrier naturally thins and pH shifts — meaning L-ascorbic acid causes irritation before it ever gets the chance to work.
The solution isn't to give up on Vitamin C. It's to use the right form — stable derivatives that work with a mature barrier, not against it.
The formulation difference
Three ways this serum delivers Vitamin C where your skin actually needs it
Each pathway targets a different mechanism of mature skin renewal.
Oil-Soluble Delivery
Vitamin C Isopalmitate
An oil-soluble Vitamin C ester that penetrates deep into the dermis without disrupting the skin barrier. Exceptional for brightening and collagen support. Ideal for the drier skin that comes with peri- and post-menopause.
No irritationBotanical Vitamin C
Kakadu Plum + Quandong
Australian native botanicals with extraordinary natural Vitamin C concentrations. Kakadu Plum contains up to 100× more Vitamin C than an orange. Quandong has evolved over thousands of years to protect skin from extreme environmental stress — it does the same for yours.
Brightening + protectionCellular Renewal
Peptides + Resveratrol
Trifluoroacetyl Tripeptide-2 and Heptapeptide-8 work at a cellular level to boost collagen synthesis and improve dermal-epidermal integrity. Resveratrol amplifies antioxidant protection. Together they address visible firmness, not just surface brightness.

How to use Power-Up C Serum
The morning protocol
Cleanse
Start with a clean, dry face. Pat gently — don't rub. Residual moisture is fine; you're not looking for completely dry skin.
Apply 2–3 pumps
Warm between fingertips and press into skin from the centre of the face outward. Include the neck and décolletage — these areas show Vitamin C deficiency first.
Layer your moisturiser
Allow 60 seconds for the serum to absorb, then apply your moisturiser as normal. Vitamin C works best as a base layer under your other actives.
Always finish with SPF
Vitamin C is your antioxidant shield against UV and environmental stress — but it works best when you also block that stress at the surface. Never skip sunscreen.
"The biggest mistake I see is women applying their Vitamin C at night. Its job is to neutralise the free radicals your skin faces during the day — UV, pollution, blue light. Use it in the morning and you're giving your skin real protection."

From the founder
Why I reformulated Vitamin C for skin over 45
"I spent years watching women give up on Vitamin C because 'it doesn't agree with my skin.' In most cases it wasn't the ingredient — it was the form they were using."
For 30 years I've been in treatment rooms working with women whose skin has changed. The women who come to me in their 40s and 50s are some of the most informed skincare users in the world — they've tried everything, and they're tired of being sold things that don't work.
Power-Up C was built around one question: what does Vitamin C delivery need to look like for a skin barrier that has genuinely changed? The answer is an oil-soluble form that doesn't require an acidic environment to penetrate, paired with native botanicals that provide their own natural Vitamin C activity. No compromises on potency. No irritation as a trade-off.

Common questions
Everything you need to know
Why is this serum different from other Vitamin C products?
Most Vitamin C serums use L-ascorbic acid — effective but highly pH-dependent and irritating to mature, reactive skin. Power-Up C uses Vitamin C Isopalmitate, an oil-soluble ester that penetrates at a skin-compatible pH. Paired with Kakadu Plum and Quandong, it delivers a genuine 25% active concentration without the drawbacks of traditional formulas.
Can I use this if my skin is sensitive or reactive?
Yes — this formula was specifically designed with sensitive, post-menopausal skin in mind. Vitamin C Isopalmitate is oil-soluble and non-acidic, meaning it does not disrupt the skin's natural pH or irritate a thinning barrier. Many customers who previously reacted to Vitamin C use this daily without issue.
Should I use this in the morning or at night?
Morning. Vitamin C is an antioxidant — its role is to neutralise free radicals from UV, pollution, and blue light throughout the day. Apply 2-3 pumps after cleansing, before moisturiser, and always finish with sunscreen.
How does this work with the Collagen Boost and Repair Serum?
They complement each other. Power-Up C delivers antioxidant protection and surface brightening in the morning. Collagen Boost and Repair targets deeper cellular renewal overnight. Together they address ageing at two levels: environmental defence by day, structural repair by night.
