Kessine

Kessine, vitamin C serum for skin exposed to the Australian sun

Kessine is an Australian cosmetics brand that sells a single product: a 30 ml vitamin C serum formulated around three Australian native botanicals. The company presents itself as a small, independent business, operated by Eagle Reborn PTY LTD T/A Kessine, based in Tarneit, Victoria, with the product made in Australia and shipped from an Australian fulfilment centre.

The brand maintains that most vitamin C serums are formulated for mild, overcast markets, and that its starting point was different: working with ingredients from environments that are heavily exposed to the sun. Its founder, Muhammad Y, created the company with the stated aim of developing a serum designed for Australian conditions rather than adapting a formula conceived for a milder climate.

Kakadu plum, Davidson plum and rosella

The formula combines three Australian native botanicals: Kakadu plum, Davidson plum and rosella, all three described by the company as rich in antioxidants. The brand argues that these plants grow in some of the most sun-battered territories on the planet, and that there is a logic in turning to botanicals from the same type of climate that skin has to face.

The product is sold as a vitamin C serum with Kakadu plum, in a 30 ml format, at a listed price of A$44.95. According to the information on its own website, it has a 5.0 out of 5 rating on Amazon Australia as at August 2026.

A stable form of vitamin C and a fragrance-free formula

Kessine uses sodium ascorbyl phosphate instead of pure L-ascorbic acid. The company justifies this choice because it is the more stable of the two, which allows the serum to keep its colour and clarity instead of turning amber on a bathroom shelf, and also because it is gentler on reactive skin. The brand stresses that this is a deliberate decision and not a cost issue.

The serum is fragrance-free, vegan-friendly and cruelty-free. The company publishes the full INCI ingredient list on the product page rather than summarising it, so that buyers can review the entire formula before purchasing.

How to apply

The brand describes a one-step ritual: apply two to three drops to clean skin, morning and evening.

What the brand claims and what it does not claim

Kessine defines itself as a cosmetic product and states that it talks about how skin looks, not about treating, preventing or curing any condition, and that it does not make claims it cannot stand behind. The company expressly states that its serum is not a sunscreen and is not a substitute for one, and that nothing replaces proper sun protection.

Direct sales and on Amazon Australia

The product can be bought directly on the brand's website and is also available on Amazon Australia. The company offers 10% off the first order to those who subscribe to its mailing list, with the code sent by email.
