"Prior to using ESK my skin was horrible, I tried lots of different skin care products, medication, saw a skin care specialist and nothing worked. It was my mum that actually found ESK and got me using the products and within a week my skin had already cleared up. I absolutely love how they feel and how reliable this brand is. I use my products every day morning and night and don't know what I would do without them!"

"So i’ve been using ESK for about 6 weeks now and i’m super happy with the results. Photo (no filter on either) on the left is before incase it’s not obvious. I have the pigmentation kit and it has made my skin feel amazing. I think there’s a difference in appearance as well. I love the ritual of putting on the different steps morning and night and I will continue using the kit now as it’s part of my daily ritual."

"I have been using ESK skincare products for about 8 months now and I’m absolutely loving the results. I’m in my 50’s and was concerned with ageing and dryness. I find the ESK products have really improved my dry skin and overall skin texture. I also find the pump application great and one pump gives you the right amount so you’re not wasting any product. I was initially drawn to ESK because it is Australian made, evidence based and cruelty free but have continued with it because I’m loving the results and find it’s great value for money. All in all I’m very happy with the products and couldn’t recommend them more highly."

"Here are my before and after photos taken 5 weeks apart. I am really enjoying my ESK skincare. My biggest concern was my uneven skin tone due to sun damage. I think after using these products for such a short time the difference is remarkable. My skin feels hydrated and plump and the tone is much more even. I highly recommend these products as they are very easy to use with the am and pm marked on the bottles. They really do work."

"Can you turn back the years? Perhaps not but it appears that you can minimise the damage that many of them caused. I have the Mature Pigmented Kit and I love it. These two photos were taken at the same time in the morning bot with no products on and a month apart. I think that my skin looks brighter, smoother, healthier and thankfully younger."

"After using ESK skincare for the past 2 months or so I have noticed a huge difference in the clarity of my skin. It FEELS so clean and fresh, and the size of my pores has diminished. I LOVE how these products feel, and how easily they go onto the skin. It’s such a simple process, clearly numbered, making it quick and easy to use. The customer service is outstanding, not to mention super- fast delivery. I will not be changing skin products any time soon! "

"I am extremely happy with ESK and have used it before. I do love the travel kit which I took to Europe when I last went a few years ago and loved the convenience of smaller containers. I do love your product and feel it has improved the texture of my skin and I feel the vitamin A and C helps to improve my complexion."

"WOW!!.... I thought my skin was in pretty good condition before I started using E.S.K and I wasn't sure if I was going to see any significant improvement. Well was I wrong!! After just 1 month of using E.S.K, my skin looks brighter, lighter and feels so much smoother. These products feel beautiful on your skin and with an easy to follow guide on how to use them, your skincare routine has become that much simpler. Delivery is quick and the follow-up customer service is excellent."

"It is still a work in progress but I am so relieved to finally see results. I never had any pigmentation issues until about two years ago. I have tried so many different products and treatments which has just made my pigmentation worse. I cannot be happier as ESK has given back my confidence and I am able to face the world again without makeup!"

"I have been using the range for around 5 weeks now and I really love the products. I have the range for Mature pigmented skin and the difference the products have made is noticeable for me. I had quite a lot of redness and lots of pigmentation. I always felt embarrassed not wearing a full coverage foundation. I also had skin that felt and looked tired with some dry patches. I noticed a difference in how my skin felt in the first week. By week 2 I was starting to see a softening of the pigmentation. 5 weeks in and I can really see the improvement. Simple regime, great products, practical packaging and excellent service."

"I have been using the ESK range recommended for eczema for one month and can already see pigmentation lightening and a softening of fine lines of my face. I had been using a very basic skin care regime so I had some concerns about using ESK initially given there were 5 different products (including a cleanser), but the products are very easy to use, the numbering on some of the products assists with this. They also smell great and feel wonderful on my skin, even the all important Zinc Shade."

"I followed the morning and evening routine to the letter. I noticed some improvements on my skin texture, smaller pore size and skin glowing/looking very healthy .Is it a miracle cure? My pigmentation did not disappear but I never expected that to happen in 4 weeks!! But it did noticeably improve. Did I like it? YES! So it is a big thumbs up from me from a quality perspective, it is gentle enough to apply everyday without any of the harsh side effects of general targeted treatments yet effective!"

"My tailored ESK skincare set has exceeded all my expectations. I actually didn’t realise how dull and badly pigmented my skin was until seeing my own 4 weeks progress and honestly being in complete shock of the difference it has made! I feel so much more confident now to let my natural skin be on show and not having to hide it behind a face full of makeup. I will 100% continue to use this regime as if it can make this difference in just one month imagine what the long term results can be. Would highly recommend them to anyone that is facing their own skincare issues."

"I am absolutely thrilled to share my experience with ESK. In just one month, I have witnessed incredible improvements in my skin. My complexion is now less red, and my skin feels nourished and hydrated. The best part is that the skincare routine is effortless, and my skin feels amazing instantly. I started with the trial size to test the products, and I am happy to say that I have ordered the full size, knowing that my skin will only continue to improve."

"I have noticed an overall difference in the feel of my skin, it feels more plump and the colour has evened out. Wrinkles appear to have less depth. I have just started to use eye serum which I am excited about. Extremely impressed with results so far, only regret is I wish I had started using it sooner."
Evidence-based Vitamin C Serum
When it comes to cosmeceutical skincare, L Ascorbic Acid, AKA Vitamin C delivers a powerful boost to your skin! It’s an antioxidant, helping combat damage done by the sun’s UVA and UVB rays. It helps boost collagen production and stabilization.
L Ascorbic Acid is anti-inflammatory which can help with very dry skin conditions and also inhibits the enzyme tyrosinase, which produces melanin in the skin. The result? Brighter skin, less fine lines and wrinkles, less pigmentation and better hydration!
So, shopping for L-Ascorbic Acid skincare is a no brainer. But make sure you’re using pure L-ascorbic acid, which is the evidence-based form of Vitamin C. Research tells us that we need L-ascorbic acid at concentrations around 10% to be effective and that L-ascorbic acid serums must be in a pH below 3.5 (acidic) to remain stable. Also make sure your vitamin c serum comes in an airless opaque bottle to preserve the integrity of the L- ascorbic acid.
ESK’s L-Ascorbic Acid serums use 10% L-Ascorbic Acid with Vitamin E, have a pH of 2.75-3 and come in airless, opaque bottles to ensure for the most hygienic and stable product.
