Alpha Hydroxy Acid

Unveil smoother skin

Alpha Hydroxy Acid

Alpha hydroxy Acids (AHAs) AKA fruit acids are naturally occurring organic acids that are used to improve wrinkles, skin elasticity, skin tone and hydration. They work by exfoliation of superficial skin cells by breaking apart the bonds that hold these cells together. This results in the sloughing off of dull and rough skin promoting the renewal of new skin cells. The result? Softer, smoother skin and less wrinkles.

Not sure how to incorporate AHAs into your skincare regime? Head to our online skin quiz. ESK has free shipping to USA and Australia as well as a money back guarantee.

"I've been using the pigmentation products for a month now, I'm very happy with the results, my brown spots have certainly faded, my overall skin is looking much better, and I'm looking forward to even greater results as I continue on using this fabulous skin care regime. I love the way my skin feels after each use and my makeup glides on to give a nice dewy effect which I haven't been able to achieve for some time. I'm feeling more confident in being able to reduce my makeup usage overall."

"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"

"E.S.K is a fabulous product. I thought I would struggle to incorporate a skincare routine in my life but after using E.S.K for a month, I realised how easy and rewarding it is to take better care of my skin. I love that all the bottles are labelled using numbers so even on a busy morning, I can certainly take care of my skin without worry."

"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."

"I have used a lot of different skincare products over the years, including professional clinical products and without a doubt, I have found ESK skincare to be the best. Their evidence based products feel lovely on my skin and my expression/age lines have softened and are less noticeable. I am lucky to be blessed with good skin, especially for my age, but ESK products are definitely making a positive difference and my skin looks and feels healthy. I am a repeat customer and will happily remain a loyal one."

"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 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."

Calming Cleanser, Reverse C Serum, Zinc Shade, Smooth Serum, Ultimate A, Pigmentation Kit, Dry Skin Anti-Aging Kit, Mature Lighten & Tighten

"My name is Marcia and at age 51 my skin is definitely on the mature side as well as being dry. I was hoping to get results to reduce pigmentation and fine lines as well as to increase the general hydration of my skin. Ive been using ESK for 1 month. My favorite product is the Reverse "C" Serum. I just love how my skin feels after it absorbs into it. I am absolutely thrilled with the way my skin is feeling so hydrated and I can really see a difference with the pigmentation. Even the skin on my neck feels soft all day long and I'm feeling confident that with continued use my results will continue to improve. Yes I would recommend E.S.K and infact, after years of breakouts and acne with no real improvement from many products, my daughter is going to try the Acne Kit range. I can't wait to see the results for her."

"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!"

"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."

"Prior to using evidence based skincare, I was suffering from chronic dryness, cystic acne and sun damage. I had tried a number of different routines; both over the counter products and prescribed. Nothing seemed to be hydrating enough! This all changed when I was introduced to ESKcare! Within days I could see a noticeable difference! My skin appeared and felt healthier, fuller and softer! My acne disappeared, my skin was finally hydrated and any irritation or itchiness was eliminated with better sun protection! The best part is that even after my purchase, the ESKcare team followed up with emails (about once per month) containing little tips to maintain healthy skin! I have absolutely loved my products and cannot recommend ESKcare products enough! This is the change everyone needs! x"

"I have been using Dry Skin Anti Aging products for almost three months and I have noticed a difference in the texture of my skin. The products are easy to use and very moisturising. When I wake in the morning, my skin feels dewy and moisturised. I also love the fact that your products are not tested on animals. I have also found the service given by E.S.K. staff is outstanding. This is the best product I have ever used."

"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!"

How do Alpha Hydroxy Acids work?

Alpha hydroxy Acids (AHAs) AKA fruit acids are naturally occurring organic acids that are used to improve wrinkles, skin elasticity, skin tone and hydration. They work by exfoliation of superficial skin cells by breaking apart the bonds that hold these cells together. This results in the sloughing off of dull and rough skin promoting the renewal of new skin cells. The result? Softer, smoother skin and less wrinkles. AHAs also work effectively against pigmentation by helping flush the pigment from the skin. Glycolic acid and Lactic acid also suppress pigment synthesis by inhibiting the activity of the enzyme, tyrosinase which is critical for making melanin. Glycolic and Lactic Acid are the two AHAs with the best evidence. Other more gentle AHAs like Malic, Tartaric and Citric acid are often included in skincare products but have much weaker supporting evidence. 

Our Alpha Hydroxy Acid skincare allows you to get your AHAs in two evidence- based ways; Our ESK Hydroxy Cleanser has 2% Glycolic acid, 1% lactic acid and Our Smooth Serum contains 3% Glycolic Acid, 1% Lactic Acid and1% Gluconolactone. Both are in many of our skin kits. Not sure how to incorporate AHAs into your skincare regime? Head to our online skin quiz.
