THE OXYGENC™ DIFFERENCE

Vitamin C is one of the most scientifically validated brightening actives in skincare. The problem is stability. Standard Vitamin C (L-ascorbic acid) oxidises quickly on contact with air and light — turning yellow, losing potency, and delivering a fraction of the benefit the formula promised. Most Vitamin C serums on the market are partially degraded before they ever reach your skin.

OxygenC™ is Skin Physics' stabilised Vitamin C complex, formulated to stay active from the bottle to your skin. Using Sodium Ascorbyl Phosphate — a next-generation Vitamin C derivative proven to remain stable at physiological conditions — the OxygenC™ formula maintains efficacy across its full shelf life. That means the brightening actives you're applying in week twelve are as effective as in week one.

For skin in its 40s, 50s, and beyond, this matters more. Cell renewal slows with age — meaning pigmentation lingers longer, oxidative stress accumulates, and dull, uneven tone becomes harder to shift. The OxygenC™ serum also combines two potent Vitamin C sources with Niacinamide (Provitamin B3) and Australian Lime Caviar Extract, rich in natural AHAs, to visibly brighten, support a more even complexion, and help defend against the daily environmental stressors that accelerate visible skin changes.

Paired with an Essential Mineral Blend of Copper, Zinc and Magnesium, it's a formula designed not just to brighten — but to fortify.

Uncommon science. Unmistakable skin.

FAQ

1. What does Vitamin C serum do for skin?

Vitamin C is a proven antioxidant active that visibly brightens the complexion, supports a more even skin tone, and helps defend against oxidative stress caused by UV and environmental exposure. Applied consistently, it can help reduce the appearance of pigmentation, dullness, and uneven texture; making it one of the most clinically supported ingredients in everyday skincare.

2. What is the best Vitamin C serum for mature skin in Australia?

For skin in its 40s and beyond, the key is stability and formula intelligence — not just Vitamin C concentration. The Skin Physics OxygenC™ Vitamin C Brightening Serum is specifically formulated for mature skin, combining a stabilised Vitamin C complex with Niacinamide, Australian Lime Caviar Extract, and a Mineral Blend to visibly brighten, even tone, and support skin resilience. Fragrance-free, alcohol-free, and silicone-free.

3. How long does it take for Vitamin C serum to work?

Visible brightening can typically be seen within two to four weeks of consistent use. Pigmentation and uneven tone take longer — most users notice meaningful improvement at the six to eight week mark with daily use. Vitamin C actives work progressively, so consistency and correct application (morning, after cleansing, before moisturiser) deliver the best results.

4. Can I use Vitamin C serum every day?

Yes. The OxygenC™ Vitamin C Brightening Serum is formulated for twice-daily use — morning and evening. Its stabilised Vitamin C derivative is well-tolerated by most skin types, including sensitive skin. Morning application is particularly effective, as Vitamin C's antioxidant properties support defence against daily environmental exposure. Always follow with SPF in your morning routine.

5. Can I use Vitamin C with retinol?

The most effective approach is to use Vitamin C in the morning and retinol at night. Vitamin C is an antioxidant that works well alongside SPF in your morning ritual. Retinol supports skin renewal overnight and is sensitive to light, making it a natural evening active. Using them at different times of day allows each ingredient to work optimally without potential pH interference. *

6. What makes OxygenC™ different from other Vitamin C serums?

Most Vitamin C serums use L-ascorbic acid, which is notoriously unstable — it oxidises quickly and loses potency. OxygenC™ uses a stabilised Vitamin C complex (Sodium Ascorbyl Phosphate) that maintains its activity from first use to last. Combined with Niacinamide, Kakadu Plum Extract, Australian Lime Caviar, and a Mineral Blend of Copper, Zinc and Magnesium, it's a multi-active formula engineered for visible results; not just Vitamin C in a bottle.

Generic Skincare questions - FAQ

1. How should I layer my skincare?

The best approach is to layer from thinnest to heaviest products after cleansing. This typically starts with a toner (or essence) and serums, followed my moisturisers and oils. Always finish your morning routine with an SPF and be sure not to mix too many serums to avoid potential skin irritation due to the various pH levels (for example, Vitamin C is best used in the morning, and Retinol at night).

2. When will I start to see results?

This depends on the product, but just like a new fitness regime, consistency is always key. For hydration, you'll notice a difference in skin's moisture within minutes using Dragon's Blood. For brightening and discolouration, you'll find a visibly smoother and more luminous complexion from using after 2 weeks using Vitamin C products. For facial sculpting and tightening, you'll notice a change after 1-4 weeks using Advance Superlift. For strengthening and repairing serum treatments, which require skin renewal and turnover, these can take up to 4 weeks for visible results.

3. Do I need a morning and night routine?

Yes, we recommend a unique skincare routine for both morning and night. Just like your routine throughout the day, your skin has different needs too. In the morning you want to prep and protect. Think layering Vitamin-C for brightening and defence from free-radicals, finished with a light moisturiser and an SPF to protect from the harsh, Australian sun. At night, it's all about repair, renewal and preparing skin for the next day. This is when you swap the Vitamin-C for regenerating serums like AHAs and Retinols, which are sensitive to sunlight. Your night routine should also include a heavier moisturiser, like the Dragon's Blood Ultra Plumping Night Cream, to smoothe, repair and replenish waterloss while you sleep.

4. How many products do I need my routine?

This depends on what you're trying to achieve. A basic routine requires only a cleanser, moisturiser and SPF. However this only addresses the bare minimum of skincare. To address keyareas of concern such as crepey skin, fine lines and wrinkles, discolouration, dehydration, hyperpigmentation or redness, we recommend gradually introducing high performance BOOST products — targeted serums, eye treatments and masks — to achieve your desired result. You can view our range of high performance serums and treatments here.

5. Does my product contain naturally derived ingredients?

Yes, we combine science-backed formulas with naturally derived actives to create thoughtfully designed, clinically proven skincare for every stage of your skin's journey. We carefully choose what goes into our formulas, and just as importantly, what does not, to ensure you're getting the best formulas to achieve unmistakable results.

6. How do I know if Dragon's Blood or Advance Superlift is the right LIFT for me?

Both Dragon's Blood and Advance Superlift rebuild long term strength and structure in mature skin. We recommend Dragon's Blood for those looking to restore skin resilience and youthfulness for a plump and hydrated complexion. The Advance Superlift range is perfect for those wanting their skincare regime to go even further. It targets saggy and crepey skin to visibly lift and recontour, improving firmness and bounce.
