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!)
