K-beauty has a new addition to the Australian skincare shelf, and this one is designed to be used just once a week.

Skin Republic’s Microdart Serum Ampoule + Spicule has arrived at Chemist Warehouse for $18.99, offering a six-treatment introduction to the increasingly popular spicule skincare trend.

The treatment uses tiny natural spicules rather than traditional needles, creating a micro-stimulation sensation when applied to the skin.

It is paired with familiar skincare ingredients including niacinamide and moringa, with the formula designed to leave skin looking smoother, more even and refreshed.

For anyone whose bathroom shelf is already overflowing with serums, creams and masks, the once-a-week format is perhaps the most appealing part.

One sachet, once a week

The treatment comes in six individually sealed 2ml sachets, with each sachet designed for one application.

The routine is deliberately straightforward. After cleansing, apply the serum to the skin while avoiding the eye and lip areas, then gently pat and press it in to absorb.

A mild tingling sensation or temporary redness may occur following application, according to the product information, so it is worth following the directions carefully when introducing the treatment into your routine.

The sachets also have a three-year shelf life, making the format particularly convenient for anyone who does not want to commit to opening a larger treatment bottle and using it several times a week.

What is inside the formula?

Niacinamide is one of the better-known ingredients in the formula. In skincare, it is commonly used in products formulated to help skin look more even and refined while supporting the appearance of the skin barrier.

Moringa is also included, adding antioxidant properties to the formula alongside its moisturising and soothing qualities.

The combination is designed to complement the spicule technology while keeping the routine focused on the overall appearance and feel of the skin.

The clinical testing

Skin Republic says independent testing was conducted on 22 participants over four weeks using Antera 3D CS, an instrumental skin analysis system from Miravex Limited in Ireland.

The testing recorded a 34 per cent reduction in visible pore count and a 31 per cent reduction in wrinkle depth over the study period. Participants also showed improvements in the appearance of skin texture and pigmentation during the testing period.

A separate consumer questionnaire involving the same 22 participants supported the reported findings.

These results should be considered in the context of the study size and timeframe rather than as a guarantee of individual results. Skincare can perform differently from person to person, and introducing a new active treatment should always be done according to the product directions. Results may vary.

The K-beauty treatment costs less than $20

At $18.99, the Skin Republic Microdart Serum Ampoule + Spicule works out at a little over $3 per sachet, giving shoppers six weekly applications in the box.

It is also dermatologically tested and cruelty-free.

The product is now available at Chemist Warehouse, making it an easy addition for shoppers keen to try the latest K-beauty-inspired skincare trend without committing to an elaborate multi-step routine.

For those intrigued by spicule skincare, now is your chance to try the six individual sachets, one treatment a week and a routine that takes only a few minutes.
