Say Goodbye to Dull Skin and Hello to Bright Luminous Skin with our Brightening Duo.

Two products that will work in perfect synergy, with the natural botanical Super Fruit ingredient the Kakadu Plum, you can be sure to improve your skin luminosity.

Kate McIver Secret Weapon EverGlow Tonic - Combined to gently exfoliate dead skin cells, unclog pores, rehydrate, brighten, smooth, reduce wrinkles and fine lines, and improve skin luminosity.

EverGlow Tonic is powered by a gentle concentration of Glycolic Acid (3.5%) and two clinically-proven natural botanical active ingredients, the Kakadu Plum and Kombucha ferment, rich in organic acids, vitamins and antioxidants that can help to increase collagen and hyaluronic acid in the skin.

If your skin is prone to breakouts, feels dull and needs some extra cleansing after wearing a full face of makeup, you should consider adding this extra skincare step to your daily routine.

The Kate McIver Secret Weapon Hyaluronic Kakadu Serum has two results-driven ingredients brought together to Illuminate your skin and Protect and Reinforce the dermis for a beautiful skin aspect. Extracted from Kakadu Plum, the world’s highest Vitamin C source and a Hyaluronic Acid with a mixed molecular weight of low, medium and high molecules will improve skin radiance & boosts skin luminosity.

Step 1 - Soak a cotton pad with Secret Weapon EverGlow Tonic and sweep over a cleansed face, neck and décolletage, avoiding eyes. No need to rinse.

Step 2 - Splash your face with cold water, leaving your skin slightly damp. Gently smooth 5 drops of Kate McIver Secret Weapon Hyaluronic Kakadu Serum over your face and décolletage until it is fully absorbed.

For best results, precede with Secret Weapon Cleansing Balm and follow with your preferred Secret Weapon Serum to seal and maintain moisture in the skin.

I am very impressed and truly love this product. The hyaluronic goes on very smooth after the toner. I have used other good products in the past, but this one has topped them all. I am just bummed that I cannot get anymore Secret Weapon Limited Serum because I started to see my dark spots lighten.

Love this duo, absolute must for a skin care regime game changer, amazing results

Fantastic results using the brightening duo. I am on my 2nd bottles of these amazing products. My skin has never looked or felt so clear and bright. The Everglow tonic makes my skin feel fresh and so clean accompanied with the Kakadu plum serum my skin literally glows, can’t live with out them both. I also use the cleansing balm & limited edition secret weapon as a whole regime and love the results. This regime has changed my skin for the better and will never look back.
