We Tested No.4 Concentrate from kit, a Plant-Based Alternative to Retinol


“Modern formulas for all skinkind” is the motto over at Melbourne-based kit and the skincare brand has the products to prove it. Since launching in 2022, kit has been using simple, effective ingredients to deliver palpable results across all skin types. Already a success story, it’s also a work in progress as its team continues to search both near and far for the best plants, adaptogens, oils, and extracts, all in a conscious effort to leave no user behind. Combine that with eco-friendly practices and packaging choices and you’re looking at a modern brand indeed.

We were fortunate enough to join kit on a recent wellness trip to Hobart, Tasmania for the launch of its latest innovative product launch, the No.4 Concentrate, a plant-based alternative to retinol. In between visits to Dark Mofo, facials, nature hikes, icy river plunges and more, we had the opportunity to trial not only the newest release but a whole range of products that make up the kit ecosystem.

This allowed us to discover exactly what it is that makes this skincare stand out. Not only is the branding impeccable, but the brand ethos is something we can really get behind; consciously formulated, sustainable and hard-working ingredients that don’t cost an arm and a leg.

Discover No. 4 Concentrate and the Wonders of Bakuchiol

If you maintain a regular skincare routine, you’re probably familiar with a widely-used ingredient known as retinol. While effective on many skin types, retinol is also known to irritate the skin of certain users, meaning it isn’t suited for everyone. Knowing as much, kit sought a healthy alternative when formulating the new No. 4 Concentrate. This journey brought the brand to bakuchiol, a plant-based ingredient that delivers retinol-like results with less risk of irritation.

Bakuchiol is naturally derived from the babchi plant with a long history of use in Western medicine. Like retinol, it helps support skin cell turnover and collagen production, making it a perfect smoothing solution for sensitive skin. It also helps reduce the appearance of fine lines and wrinkles to round out its retinol-like functionality.

In addition to bakuchiol, No. 4 Concentrate features the following ingredients:

  • Bladderwrack is a seaweed extract with moisturising, antioxidant, and soothing properties.
  • Blueberry extract is chock full of polyphenol antioxidants.
  • Aloe Vera remains best known for its ability to soothe and hydrate the skin.
  • Tasmanian Pepper Berry is an Australian botanical that’s used for its antioxidant properties.
