Vitamin C is one of the most reached-for ingredients in skincare, and for good reason. As an antioxidant, it helps support skin against the daily stress of a harsh environment. But not every vitamin C serum is built the same, and in a climate like Australia’s, the differences matter more than most people realise.
Here is what actually separates a good vitamin C serum from a forgettable one, and where Kessine fits in.
Look for a stable form of vitamin C
The most common form of vitamin C, pure L-ascorbic acid, is famously unstable. It oxidises when it meets air and light, which is why so many serums turn orange or brown in the bottle within weeks. Once that happens, you are paying for something that has already lost much of its value.
Kessine is formulated with Sodium Ascorbyl Phosphate, a stable derivative of vitamin C. It holds up far better over the life of the bottle, so what you apply on the last day is closer to what you applied on the first.
Look for antioxidants beyond just vitamin C
Vitamin C works hardest when it has support. Kessine pairs it with three Australian native botanicals: Kakadu Plum, Davidson Plum and Rosella. Kakadu Plum is one of the richest natural sources of vitamin C in the world, and all three are rich in antioxidants that complement the serum’s core.
The result is a serum that feels considered rather than clinical, and that carries a genuine sense of where it comes from.
Look for fragrance-free
Added fragrance is one of the most common irritants in skincare. Kessine is fragrance-free, which keeps the formula simple and lets the active ingredients do the work without anything extra along for the ride.
Why Australian-made matters
A lot of the vitamin C serums on Australian shelves are made overseas and shipped in. That is not a flaw in itself, but it does mean longer supply chains and formulas designed for other markets.
Kessine is made in Australia, with Australian native botanicals, for the conditions Australian skin actually lives in. Our sun is not gentle. A serum built with that in mind starts from a more honest place.
Where Kessine fits
Kessine Kakadu Plum Vitamin C Serum is a 30ml facial serum built around three ideas: a stable form of vitamin C, Australian native antioxidants, and a clean, fragrance-free formula. It is vegan-friendly, cruelty-free, and made in Australia.
It is designed as a simple daily step. A few drops on clean skin, morning and night, and that is the whole ritual. Skin looks fresher and brighter over time, without a complicated routine.
If you have been looking for an Australian vitamin C serum that is made here and built around native botanicals rather than imported and generic, Kessine is worth a place on your shortlist.
