How do I apply the Secret Weapon Serum?

Two pumps morning and evening post cleansing. Massage thoroughly. You can use moisturiser also if you wish. This product works differently depending upon your type of skin. It is for full facial rejuvenation. We recommend patch testing the serum behind the ear, 24 hours before facial use. It is always advised to start off slowly, applying once per day and building up to twice daily.   It’s very important to introduce one new product every 4 weeks to ensure you know which product may not suit your skim.

If I have Acne what products and tips can you suggest?

We suggest you double cleanse and steam your face each evening followed by the application of the Secret Weapon Serum Limited Edition.

Will it help Melasma?

Customers have enjoyed amazing results and their reviews are visible on our website.  We would recommend the Secret Weapon Serum Limited Edition to support pigmentation unless you have sensitive skin then we would recommend the Original.

 Can I use your products when pregnant?

 There is nothing nasty included in our skin care. We always recommend you patch test for 24 hours prior to full application and try one new product at a time.  Also, all ingredients are listed on our website. 

What is the step by step routine for the Trio of products?

Step 1 - Cleanse your skin with our Cleansing Balm and use your Kate McIver hypoallergenic Bamboo and Cotton hot cloth to remove. Splash your face with cold water leaving your skin slightly damp⠀⠀⠀⠀⠀⠀⠀⠀⠀

Step 2 - Apply your hyaluronic serum to damp/wet skin ⠀⠀⠀⠀⠀⠀

If your skin is very dry and the air is also very dry, then leave your skin wet, not dripping wet, so that the hyaluronic serum doesn’t slide off your skin, but still wet rather than damp.

Step 3 - When the serum has absorbed into your skin, which will only take a moment, then you need to apply your Secret Weapon Serum over the top of the Hyaluronic serum, as this will seal the hyaluronic acid and VitC into your skin.

What is the Comedogenic rating of the Secret Weapon Serums?

Many skin care products contain comedogenic ingredients that can cause or exacerbate acne prone skin. If you are acne-prone, you will want to initially stick with products/ingredients that are predominantly 0's, 1's and 2's. None of the ingredients within the Secret Weapons Serums are above this rating. We suggest that you never test more than one new product at a time on your skin as it can take several weeks for a "problem" ingredient to start showing on your skin. Give at least 4 weeks before adding another product into your daily skin care routine. If you don't do this, you may be liable to blame the wrong product for your problems.

Fantastic as always

I can’t fault this trio at all. My skin is the best it’s ever been. Even down to the packaging-it’s so luxurious in my bathroom cabinet to using twice a day. I’m a loyal customer now for last couple of years and take advantage of offers too. Thanks guys!

Everything you need and more!

I highly recommend this product! I used the oil and the balm myself as well as the oil in my makeup kit. It meets all your skin care needs, it’s gentle, it’s kind and norishes.

Best product I’ve used

After having my children my skin took a turn for the worst I almost had acne all over my jaw,it was sore and really knocked my confidence.
After trying countless products I started using the secret weapon serum a few years ago which dramatically changed my skin for the better.
I now use the balm and the hyralronic serum together and I couldn’t recommend them more

It’s just amazing!

Been using this now for about 2yrs and I can honestly say I don’t think I could ever be without it. Nothing compares. It’s really helped even out my skin tone and I’m prone to dark patches. Love it!


I have an autoimmune condition which causes a fleeting butterfly-shaped redness across my nose and cheeks. My skin is also very very sensitive, especially in those parts and dry. I suffer from oiliness which is due to dryness. This serum has really helped. I used the limited at first as I am acne-prone but it was not hydrating enough for me. I use this alongside the hylauronic serum and the balm and I am so happy with the results. My skin isn’t oily, is calm and comfortable. I get the odd spot but I don’t mind those so much, as long as I’m not itchy I’m happy! (Left picture is before I started using this - it’s likely that my rash has faded somewhat due to health fluctuations but the serum has helped it along for sure!)
