"Hi, my name is Kelly and I have suffered with problematic skin for most of my life. I had terrible acne and chicken pocks as a child that resulted in scarring. Then along came the fine lines and wrinkles. In just under two weeks, I have seen a massive change! The regime is incredibly easy to follow, you don’t need much of it and it is an Australian product! I am finally proud of my skin and cannot wait to see what my face looks like in a month! I am so grateful! Thank you Esk!"

"I would just like to say how impressed I am with ESK skin care.

I turn the big 60 this year and have be looking for a skin care for mature skin. I was watching Sunrise and Ginni came on talking about ESK. So I thought I would give it ago and I loved the fact that it was made in Australia. I love the way the cleanser made my skin feel so clean and light and the way the products sunk straight into my skin. Which I have been looking for forever. Most products just sit on top of my skin which is frustrating and can be very expensive.

My skin looks smoother and plumper. Finally something that works 😊 Thanks ESK"

"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."

"So I've been using ESK Skincare’s Hydroxy Overnight Mask a couple of nights a week for a few weeks now and I am definitely impressed. It leaves my face glowing in the morning and doesn’t let it dry at all. Super hydrating mask! I've also used it to spot treat any breakout, dry and chapped skin! Don't you just love a product that not only works, but oh so versatile too!!!"

"I have been using E.S.K now for 4 months and the difference I have seen and felt is beyond amazing. Being from the health care industry myself I know the importance of evidence based and scientifically tested products. I have searched for years to find a skin care range that is both gentle and safe but also effective, my skin has never been clearer. My pigmentation and skin tone are now even and I feel like I have a healthy glow. I am now happy to go without makeup and I can’t recommend E.S.K products more highly. Thank you."

"I had blotchy skin tone and at aged 50 wrinkles appearing. I have been using ESK for a year now and it is a top quality facial skincare product. My skin tone is much more even and the redness is gone. Both photos are taken without any makeup. I use the Pigmented/Age Spot Kit on my skin. Thank you Esk for developing this skincare range."

"I’ve been using the pigmented skin kit for a month and have noticed that my skin is now smooth and soft, whereas before it was rough and patchy. Areas of pigmentation are lighter and less apparent. I’ve found the product to be pleasant to use and I love the smell of the cleanser. My travel kit is also lasting a lot longer than I expected!"

"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."

"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."

"I had been looking at trying ESK products since reading about them in Dr Ginni’s book at Christmas time and when my sons asked what I wanted for Mothers Day I suggested the travel size Pigmented Skin Care kit to see if I liked the products. I am so glad they took me up on the suggestion…I absolutely love them (the products and my boys). I noticed a difference after a week and after 4 weeks I am super happy. My skin is softer, the pores are not as obvious and my face just feels and looks healthier. I was amazed to see the difference when I took a photo after 4 weeks."

"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 was very sceptical about this skin care range can it do what it claims to, it most certainly can I have noticed a big change to my skin it is alot clearer feel of redness and my pigmentation has improved ALOT! So if in doubt try it you will be very happy with the results and so little is needed so will last a long time alot more than other products on the market😊😊 plus not much makeup will be needed to cover skin as it glows"

I am so impressed with the products I use.I have been using my products for around 5 weeks, just re-ordered another cleanser. My face has never felt so soft and supple with a better skin tone, looks fresher & plumper. Don’t need a lot of products to achieve the results I’m after.

"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."

What is 4-n-butylresorcinol?

Looking for a skincare solution to pigmentation? Pigmentation affects a quarter of pregnant women and more and more of us as we age. Genes play a role as does sun exposure. It can be blotchy pigmentation, “age spots” or solar lentigines or can result from inflammation of the skin, after acne. 

Treating pigmentation is a marathon, not a sprint, with benefits often taking up to 3 months to appear. The ingredient, 4-n-Butylresorcinol directly inhibits the activities of tyrosinase and tyrosinase-related protein-1 (TRP-1) which are enzymes essential for making the melanin pigment in the first place. Other tyrosinase inhibitors, like Hydroquinone are as effective as 4-n-Butylresorcinol but can cause irritation and even rebound pigmentation when you stop using it. These are side effects we don’t see with 4-n-Butylresorcinol. 

ESK’s 4-n-butylresorcinol skincare uses evidence-based formulations to tackle pigmentation. Our Enlighten has 0.1% 4-n-butylresorcinol with 5% Niacinamide to deliver effective results. For optimum results for pigmentation, we recommend combining Enlighten with our other evidence-based products in our Pigmentation or Multi Fade kits.
