The Kate McIver Secret Weapon Limited Edition Serum fits into your daily skincare routine with ease.

For best results, it is recommended to cleanse your skin with the Kate McIver Secret Weapon Cleansing Balm, then apply the Kate McIver Secret Weapon Hyaluronic Kakadu Serum prior to using the Kate McIver Secret Weapon Limited Edition Serum.

To use the Secret Weapon Limited Edition Serum, apply a few drops to a cleansed face, massaging in until it is fully absorbed. If you're unsure, use a tissue to blot any excess away. A serum will not sit on the surface like moisturisers.

*Please note - if you have not used this product previously, we advise you to patch test the serum for 24 hours before use. To do this, apply a couple of drops behind the ear. If irritation occurs, discontinue using the product.

Love it

Great product. Feels great on my skin but also it's calmed and balanced my skin. Minimal breakouts since starting it which is great. My skin feels hydrated with lout feeling greasy. Highly recommend.

Zhane T
Couldn't recommend enough!

I have been using this serum for the past 2/3 years and when I run out my skin texture and overall appearance takes a hit and there's a noticeable difference. The only serum that is non-greasy and doesn't cause me to break out. I like in Dubai now and even in the heat, the serum is still non-greasy. It feels so lovely on my skin! I ordered the serum last week and even being in Dubai the delivery is super fast. I love this serum and the results/benefit it has had on my skin.

Alison Byrne
Best ever

This is THE best product I have ever used on my skin (and I’ve tried a lot!) my face was covered in acne December 2020 now my skin is completely clear and the texture and skin tone has changed so much! I will never use anything else it’s amazing! If your unsure about trying it I’d definitely say go for it it’s amazing!

Stephanie Upton
Great product

I love this product, I use it day and night and it makes my skin feel and look great. I even told my daughter about it and she loves it too.
I used to have problem skin, but this product erases any age pots and keeps skin clear.


Perfect for my skin when I have breakouts - spots disappear within days.
