Intensive C Pro-Collagen

Pure vitamin C, kept alive

Ascorbic acid, the form with the deepest research record, degrades quickly in water. This formula suspends it in a near-waterless silicone base instead, so it stays potent in the bottle and activates on skin contact. The pay-off is real L-ascorbic acid without the short shelf life.

The collagen pairing

Vitamin C is a required cofactor in collagen synthesis; the two signal peptides, including palmitoyl tripeptide-38, associated in research with increased collagen markers, work the messaging side of the same process. That pairing is the ‘Pro-Collagen’ in the name.

Antioxidant depth

Rosmarinic acid, vitamin E and the Australian native complex extend the antioxidant network, with glycosaminoglycan-precursor sugars supporting the skin’s own matrix.

Morning by design

Antioxidants earn their keep in daylight, under sunscreen.

Skin serious about firmness, fine lines and tone, and vitamin C veterans wanting the pure form rather than an ester.

Worth knowing

Pure ascorbic acid can tingle briefly on application, especially on sensitive skin, that is the acid, not an allergy, but patch test if your skin runs reactive. For a gentler entry to vitamin C, Extreme C 20’s ester form is the softer landing.

Mornings, smooth four to five drops over clean, dry skin before moisturiser and sunscreen.

The silicone-silk texture doubles as a smoothing base under SPF and makeup.

Use alongside

Daily SPF, the defining pairing, and Multi B Plus (thinnest first). Evening retinoids complement from the other end of the day.

Keep apart from

Exfol A Plus in the same application; strong acids and pure vitamin C compete. Mornings C, evenings A.
