Rosacea Skincare Kit - Anti Redness

"I am so pleased with the progress my skin has made. Due to health reasons I have never been able to treat my rosacea with medication and in the past all the topical treatments I tried didn't seem to work for me. I just found good makeup and didn't go outside without wearing it.

(Side point - I love the blog tips about rosacea since they are really good information for people who are still struggling with it)

Now I feel much better about myself now my skin is improving, thank you so much for this. Because my skin is improving I finally convinced my husband to buy ESK too!

Thanks, Leslie"

"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!"

Really enjoyed these acne microneedle patches! I always have random breakouts so I will definitely will be carrying these around for those emergency breakouts...

Smooth Serum

“I had the worst breakout at 40 and needed to change the products I had been using. I came across ESK and after doing some research felt this would be the best treatment for me to try. After 5 days of using the acne package my skin had changed for the better. A month along and my skin has improved so much. Hardly any breakouts and my skin is glowing with pigmentation lightening. Cannot recommend ESK enough”

I feel like I have a brand new face. My skin is smoother and softer, dark spots have faded. It's taken years off in a really short time.

Everyone needs to know about ESK!"

Spotless: Microneedle Patches

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!!

"I noticed a massive difference in the redness and protrusion of my pimple. It make the breakout completely flat against my skin and heal way faster than my pimples usually do! Usually the bump from a pimple is raised for a while, but spotless made the bump go back to normal overnight."

"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."

Ageless: Microneedle Patches

ESK eye patch trial. Super easy to use. Once applied the patch blends in well against the skin. I applied the patch at night after my normal evening skincare routine (using ESK 4 & 5+) and left it until morning. As a 60 year old with sun damaged skin, I found this product to be brilliant with noticeable results to skin tone and pigmentation after the 12 day trial.

Ageless: Microneedle Patches

Please find attached my before and after pics for the patch review. Left eye before, right eye after 12 days of every second day applying a patch to my under eye.

I found the patches easy to use and I think they added more moisture to the fine skin under my eye.
They made the under eye more plump and my dark circle didn’t seem so dark.
Thanks for the opportunity to try these, I love trying your new creations. 😊

Repair +

As for the Repair +, I absolutely loved it. It was exactly what my skin needed. It's super moisturising without feeling heavy or greasy. My skin feels so much softer and I think it looks better as well...I'll be adding it to my skincare routine.

ESK has been the one and only thing that has helped my skin - and quickly! I have suffered from hormonal acne for years, it was red, and sore, and I would barely leave the house without make up on, I was so embarrassed. Within a few weeks, all of the redness was gone, half of my acne settled down and it has just kept on getting better and better. Not only did these products get my acne under control, but the texture of my skin became smooth, my pores shrunk in size and the fine lines I had started to get around my eyes have even smoothed out! What! Even my scars are disappearing, and I have been previously told the only way I would be able to get rid of them would be laser procedures...I tell everyone I can about ESK, as it's been some of the best products I have used in my life!

"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"

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."
