Secret Weapon Serum - Original - Normal and Dry/Sensitive Skin

2021, Beauty Shortlist Award Winner, Secret Weapon Original is an Award-Winning product. It is a Double Serum that works for Normal, Dehydrated, Sensitive Skin. It has become the go-to skincare for NHS and frontline workers when wearing PPE and experiencing 'Maskne'.  

Kate developed her Secret Weapon to diminish the effects of her treatment, darkness, skin-ageing, lack of radiance, bringing back a Glow, Firmer Skin, and reducing the appearance of fine lines.

When massaged into the Skin, the Serum works its "Magic" on the epidermis, supporting cell rejuvenation.  

The ingredients within the Secret Weapon Serum Original are combined to achieve a hydrating Glow.

We have chosen a few key ingredients to explain why the Secret Weapon Serum will help support your skin through the Winter.

GLA is a type of fatty acid that your body converts. The substance acts like a hormone in your body, helping reduce inflammation.

Borage oil is said to have the highest GLA content compared with other essential oils. It has shown promise in research for inflammation.

SEA BUCKTHORN OIL is another critical ingredient known for being a great skin repairer; the Secret Weapon Serum's smell and colour are from this oil. Olive Squalene is very similar to human sebum; therefore, it gets absorbed quickly. It helps the skin retain moisture and smooths out blemishes such as age spots. More importantly, it boosts cell regeneration and oxygenation.

NATURAL and contains absolutely NO ChemicalsParabens or EDC's. They are entirely vegan and formulated to rehydrate the epidermis and seal in the moisture, perfect for Winter Skincare. 

Skincare without Alcohol, without Perfume, without Parabens.

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!)

Eczema prone skin

This serum has literally changed my life!!! I can’t believe how amazing it is. I will never not buy this stuff. My skin has always been bad with eczema and sensitivity, this serum has changed that. I do still get eczema of course but it’s nowhere near anything like it was! My skin is glowing. Thank you so much Kate McIver you’ve given me such a confidence boost I hardly ever wear makeup now!

This is everything you NEED!

This is one of the best products I have ever used in my life and seriously i cannot recommend Kate McIver skin care products enough!!
From the serum to the cleansing balm that i even use as face mask and my skin has never been so perfect, smooth and what a GLOW - it’s just so amazing! If you haven’t order it already do it and thank me later because i know you gone love it!

Being a front line worker and has been working with corona patients sense february last year and wearing face mask all day long and same when I’m working nightshift 10-15 hours has really affected my skin, the air in the hospital and the face mask has really destroyed my skin a lot and it’s so hard to take care of yourself when you see others struggling to survive but Kate Mclver products has really been the only thing i can’t be without and that i have used every day.
After using face masks all day/night so many hours since february has created scars on my face, but these products have been a miracle for me and saved my skin, this is a luxury treat for my skin!

My skin feels and looks better today then before, I have so much more glow now, no scars and most of all you can see the difference between before and after!! My skin has never been in such good condition and i truly believe its down to this product.
I really recommend all the products from Kate but my favorite one is the Secret Weapon Serum - Original - Dry/Sensitive Skin and Cleansing Balm!

Love from Sweden

Chin saving serum!

I have always had spot prone skin however since the pandemic began and having to wear face masks in work as I am a nurse, to say my face suffered was an understatement. I was breaking out in so many spots which were very sore, some were just sore hard lumps under the skin which just did not seem to go and just got progressively worse.
A friend told me about the secret weapon serum and my face agreed with it straight away and I seen great improvements. I always have to make sure I've got the serum in otherwise even a day without it and my face will get worse again.
I now put it on my skin under my mask at work and it acts as a great barrier for the 13 hours. Thankyou so much.
