"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!"

"I have been using your skincare for quite some time now. Recently I had a large break out on my chin- I ordered the kit suggested for acne. I cannot believe the results and how quickly they were reached! I’ve attached some before and after photos. This was within a week of using the products- a notable difference. Thanks for giving the confidence of great skin!! It is magical skin care!"

"I have been so grateful for ESK, after having my son, my skin became dry & irritated due to hormones and sleep deprivation! And my personalised ESK skin care routine cleared all the irritation & dryness up, plus it was a nice self-care routine to incorporate into mum life!”

"In these photos I used the mask twice- once as a full face over night mask and once as a spot treatment on my blemishes. It assisted in reducing my blemishes significantly, making them no longer inflamed and sore. I really enjoy this product as a spot treatment but also as an overnight mask I wake up with the most gorgeous and glowing skin!"

"I’ve never been so excited to share my results & most importantly my love for ESK Skincare.. I’ve been using their products for about 1 year now and I’ve never been so happy with the state of my skin. After suffering from Acne for 5+ years, I was recommended ESK from a family friend, since then I’ve never looked back.. Within 3 weeks of using the products I noticed a huge difference in the texture & size of my Acne. I love that ESK is evidence based skincare, uses scientifically tested products and really cares about their customers. After spending years and years trying skincare products, I’m so glad I found ESK.. never looking back!"

"Acne, rosacea, uneven texture and tone, hormonal breakouts resulting in a lack of confidence. I have taken a before photo with make up on (to cover up my skin issues) and an after photo with no make up on. I can not thank ESK enough for helping me feel comfortable in my own skin again and feel confident without wearing make up! It has made my morning and evening routine quicker and easier, it has strengthened my skin in a short time and most importantly, it has made me feel good about myself!"

"I absolutely loved spotless patches!! I get some super stubborn hormonal acne and adding spotless as an additional product was perfect in my regime! I saw immediate results overnight, major reduction to size and colour. I loved how easy and unnoticeable they are!!"

"My experience - My skin has always been terribly hard to control acne wise. I have struggled with acne for 15 years and have tried almost every product under the sun (or so it feels). I am used to a lot of cystic acne along the jawline and neck. After using these products, my skin broke out into a lot of tiny bumps and texture. My skin got significantly worse but I was supported all the way by Tess. I am persevering and can happily say the last few days my skin is beginning to clear. I do have significant scarring and a few big bumps but the overall skin health is beginning to improve again. I cannot fault the customer service and support from your team! I am truly hoping this line are the products I have been dreaming of in the long run!"

"My skin has never been super great but it hasn't been super problematic either. It's that traditional combination skin that gets a lot of hormonal breakouts. At 31, I'm a little bit sick of having breakouts AND developing lines as well. I'm all for aging naturally and at the same time, slowing down the process and caring for my skin is important to me. I decided to try ESK because I appreciated the evidence base and the fact that the recommended starter kits didn't have a million different things to do. I work in a rewarding yet demanding job with long days and I need a skin-care routine that is simple and effective. ESK has definitely been that! I've been using it for just over a month now and I have definitely noticed a difference. My skin is a lot more firm and pigmentation has decreased. My usual monthly-hormone breakout was greatly reduced as well. One of the most wonderful aspects of my ESK journey so far has been the customer service. I have NEVER experienced such individualised, supportive customer service and I think that demonstrates how much this company actually wants to help their customers (rather than just getting their money). I highly recommend this brand of skincare and am so glad I found it."
