With all this ‘maskne’ about town lately, I put the Kate Somerville Eradikate Blemish treatment to the test and let me day this… IT IS TRULY MAGIC IN A BOTTLE! 🔮

This bottle of magical elixir contains 10% sulfur so really packs a punch to your spots! If you caught yesterday’s blog post ‘Everything You Need To Know About Sulfur’, you’ll already know that sulfur works by killing acne causing bacteria on the surface of the skin (P.acnes). It also absorbs sebum (oil) and draws out the impurities from your spots causing them to dry out and shrink. Whilst also doing all of this, sulfur also works to exfoliate the skin, removing dead skin cells and preventing further clogged pores. It manages to perform all of these tasks more gently than both benzoyl peroxide and salicylic acid. Did I mention that as well as being antibacterial, it’s also antimicrobial and an antiseptic!

Sulfur, in my opinion, really is an underrated ingredient and one that you should definitely have in your spot-fighting arsenal!


BRAND: Kate Somerville

PRODUCT: Eradikate Blemish Treatment

INGREDIENTS: Isopropyl Alcohol, Aqua/Water/Eau, Zinc Oxide, Sulfur, Camphor, Magnesium Aluminum Silicate, Salicylic Acid, CI 77491 (Iron Oxides)



  • 10% sulfur (the highest amount allowed in an acne product, per the FDA)
  • Salicylic acid (a beta-hydroxy acid that gets deep into pores and clears them out) 
  • Zinc oxide (absorbs excess sebum production)

I’ve Got *Insert Skin Type Here* Skin, Can I use It?

If you get spots then you may benefit from using this treatment, regardless of your skin type! This blemish treatment is a fast-acting spot treatment for those unexpected blemishes! 

Of course, if you have very sensitive skin then proceed with caution as this is a very strong treatment, in my opinion. Everyone who uses this should conduct a patch test first to see how their skin copes with it!

Remember, if you are taking Roaccutane this blemish treatment is not appropriate for you. Since combining Roaccutane and sulfur products could lead to excess peeling, itchiness, drying and redness.

My Experience With It

To begin, my experience with sulfur-based acne treatments is not new! Prior to trying the Kate Somerville one, I was using Mario Badescu version for around 3 years. I liked it but didn’t love it! In comparison to Eradikate, it’s nowhere near as potent in my opinion.

So, when I started experiencing ‘maskne’ back in the summer, I was really on the lookout for something a bit stronger. Despite already using salicylic acid, azelaic acid and retinoids in my routine, pesky, painful spots were still managing to form with all the mask wearing. So, I began my research and came across this Eradikate blemish treatment. The reviews seemed to be very good and I had seen lots of people in the Instagram skincare community giving it rave reviews, so I decided to give it a whirl!

From The Very First Go…

… I knew this was going to be a permanent fixture in my routine! Lately (thanks to masks… have I blamed them enough yet?!), I have been getting around the clock acne around my mouth, chin and cheeks (as opposed to just getting monthly outbreaks). The spots are often red, painful spots that slowly come to a head – the kind of spots sulfur loves!! So, as soon as this baby arrived, I cracked it open, grabbed a fresh cotton bud, dipped it down into the magical pink paste and applied it to my angry spots. Granted, I was walking around the apartment looking like a version of Mr Blobby (if you know, you know), but I didn’t mind because I had a good feeling about this product!

By morning time, the remaining bits of pink paste all over my face had turned dark pink in colour. Underneath I could visibly see my spots had gotten smaller and flatter, they were also significantly less painful and less red! Now, annoyingly, I’ve not taken any before and after shots of my spots so, you’ll just have to take my word on this one!! I will try and remember to do so though and add the photos into this blog! You probably won’t have to wait long, a spot’s most likely brewing now as I bitch about them in this blog post…

Fluke Occurrence?

Now, I did wonder if my initial experience was a fluke but no, every time I’ve turned to this product, I’ve had the same results with my spots! Of course, there have been times where the results from this pink paste have not been so dramatic. Particularly when applied to those kinds of spots that are just swollen, red lumps. Sulfur doesn’t tend to work so well on these spots (they’re called inflammatory spots), however, it has certainly helped in drying them out!

Come On, There Must Be Some Downsides?

Like with anything, you have to use this product in moderation! It can be EXTREMELY drying! I went through a very bad phase of applying this AM and PM because I was WFH so not seeing anyone. However, as you can imagine this was too much and the areas where I was applying this product became sore, dry and stingy. Especially when considering I was also using a salicylic acid serum 2-3 times per week and my retinal serum 5 nights a week. So, I had to have a chat with myself and limit my usage right down!

Another thing I noticed was that when the weather changed in the UK, becoming very cold, my skin barrier became compromised. Anything applied to my skin (including this blemish treatment) caused stinging and so I had to stop using this for around a week or so and focus on just barrier care! Once my barrier was stronger, I had no problems using this treatment again.

Lastly, I have to mention that if you check out most of these ingredients on Paula’s Choice Ingredient Dictionary, you will see that most of them are rated poor due to being potentially sensitising. Normally this would bother me! However, this is a targeted spot treatment which is applied to a spot only and not the entire face and so, in that case, I’m not worried! I also don’t have sensitive skin. Plus, I had already used this product before looking at the ingredient rating, so I myself, know this product works and doesn’t cause me irritation. It may cause me some dryness, yes, but my spots are reduced in size and clear up quicker than they would without this product! 

How Do I Use This Product?

According to the expert (Kate Somerville):

Use in the evening, after cleansing. Do not shake bottle, but simply dip a clean cotton swab to the bottom and apply only the pink sediment to the affected areas. Let applied product dry and rinse off in the morning. Use as directed. If bothersome dryness or peeling occurs, reduce frequency of use. Do not use this product if you have very sensitive skin or if you are sensitive to sulfur.

So, yes, like KS advises, I use this treatment in the evenings only and as my very last step after cleansing, toning, using serums, moisturiser and oil! I also make sure that I apply this treatment at least 30 minutes before hitting the pillow, to give the pink paste a chance to dry. Naturally as you sleep some of the pink paste that has dried falls off in a powder form but this is normal and doesn’t make the treatment less effective! For me, most of the blobs are still in place in the morning when I wake up, anyway!

The most important thing to remember is NOT TO SHAKE THE BOTTLE! If you’ve dropped it on the floor (I have many times…), just simply upright it and let the pink paste settle to the bottom of the bottle again before using.

Another thing I should mention is that, ideally you shouldn’t use this product on the same nights you’ve used your acid or retinoid products. I have, however, and haven’t experienced any irritation but proceed with caution if you plan to try it!

Eradikate, Kate Somerville

Gimme The Deets…


30ml = £22. FYI, I’ve been using this blemish treatment almost nightly since the end of September and I’m not even halfway through it yet!

Where Can I Buy It?

You can purchase this product directly from the Kate Somerville website, Space NK, and Cult Beauty, to name a few.


In regards to the time you have to use the product in, once opened, it lasts 12 months. In terms of storage, nothing special is required but just make sure it’s somewhere out of direct sunlight and on a steady surface.

Stick Or Spin Again?

STICK, STICK AND STICK AGAIN! I will, hand on heart, never be without this acne-fighting treatment! It is a game-changer! Got an active spot, pop it on and let it work its magic. Feel a spot brewing beneath the surface? Pop this pink paste on and watch it not even surface! Honestly, it’s magical and I really don’t think that you would regret trying this. 

Sam rating, 100 out of 10! 😂
