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

We are delighted to add this product to our vegan collection, which is suitable for all skin types and is to be used by anyone who wants to GLOW wherever they go!

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.

EverGlow’s natural fragrance derives from Orange Floral water that has been used as its base for it to soothe, tone and balance your skin. EverGlow will not only brighten your skin, but your mood, as the fragrance transports you to the orange groves of Spain.

All ingredients work in synergy to refresh your skin by drawing out dirt, oil, and impurities, which ultimately shrinks pores and refines your skin’s complexion.

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.

Glycolic Acid – 3.5 % Alpha Hydroxy Acid (AHA)
Concentration at this level is considered very mild, and it is formulated at a pH between 3 and 4, considered the optimal range to exfoliate gently.

The benefits include exfoliating dead skin cells, reducing fine lines and wrinkles, fading hyperpigmentation, brightening and sooths complexion, fighting acne, hydrating dry skin and increases penetration of other ingredients.

Kakadu Plum Extract
This Australian superfruit is the world’s richest botanical source of Vitamin C – up to 100x more than oranges. This high performing ingredient is crucial for collagen production, which reduces wrinkles, improves the appearance of fine lines, induces skin brightening and improves skin luminosity. It protects and reinforces the dermis to reduce the appearance of ageing signs.

Black Tea/Kombucha Ferment
This wonder ingredient is packed with vitamins and acids, such as gluconic acid, glucuronic acid, lactic acid, vitamins B1, B2, B3, B6, B12 and C, and folic acid, which are essential for healthy skin and a more youthful appearance by boosting the energy of skin cells.

The acids in Kombucha help rid the skin of dirt, oil and dead skin trapped deep inside the pores, helping reduce acne breakouts.

Some of us are born with freckles, but sometimes, tiny dark spots form over time. The Citric Acid in Kombucha helps slow the production of melanocytes and helps fade existing dark marks. Kombucha also helps restore the natural pH balance in the skin.

Kate created this product, with her mindset of “life is too short and no matter what you are going through mentally or physically, you have the right to look and feel the best you possibly can”. Her aim was for people to ‘glow’ and ‘radiate’ after using the then unnamed product.

Whilst the formula of the tonic was complete some time ago, it was only given its name ‘EverGlow’ recently. Whilst Chris, Kate’s husband, was reviewing old pictures and videos, he came across an idyllic, almost heavenly video Kate took whilst being driven near their home through a snow-covered landscape, with her favourite Coldplay song, Everglow, gently playing in the background. The lyrics now so much more meaningful.

The name EverGlow Tonic felt like a perfect celebration and tribute to Kate. We are so excited to finally bring this to you, and couldn't be more proud of Kate.

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

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

Look this serum. A little goes far. Great skin care.


Love this, I’m on my 5th bottle!

Awesome Product!

I just love the clean skin feeling I get using the Everglow Tonic. I have used many many different products over the years (some extremely pricey!) and haven’t come across a better one for making my skin glow after using like this one and any serum/ moisturiser combo I use afterwards melts into my skin perfectly. Very happy and have just ordered my 5th bottle!!

Everglow Tonic

I never used to use a skin tonic but recently thought I would try this and now use it all the time, leaves my skin nice and fresh and clean, it has become a permanent part of my daily skin care.


Liked this but can only use once a day, twice made my skin go a bumpy. Will probably purchase again when I run out. But am waiting for the limited edition serum to come back into stock first.
