Frequently Asked Questions
No, just apply in the morning after cleansing.
Yes, Vitamin C typically starts off clear and will gradually transition to a light yellow, darker yellow, and eventually dark orange/brown as it oxidises (exposed to light, heat, and air). Over time, once your Vitamin C becomes brown, it's time to dispose of the product as it loses efficacy and may be harder to tolerate.

"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."

"Have really noticed a difference in my rosacea in the short time I have been using the ESK products in the rosacea kit. The bottles are numbered which makes them a breeze to use and the products themselves feel amazing on my skin. Will continue to use these products (and add a few more!) as am sure I will continue to see results the longer I continue to use them."

"I started using ESK hoping it would help reduce the redness on my cheeks. My other area of concern was the crepey skin on my neck. I have been using the rosacea kit for a month now and really love the products. The texture of my skin feels amazing and I think the redness has reduced.... hopefully more in the coming months! I think my neck has seen the biggest improvement. I think Enlighten is my favourite product, but I love using them all. I love the simplicity of the routine and how beautiful my skin feels after using it. Thank you"

"I was searching for an Australian product that could assist me in my ageing skin and came across E.S.K. I was really impressed with the quality of their products and the customer service was extremely knowledgeable and helpful. After starting the pigmentation product line several weeks ago, my skin is feeling more hydrated and I am looking forward to seeing further results with my pigmentation and texture over the coming months."

"I've had significant freckles since I was a kid (and yes, my parents were strict on
sunscreen use!) and as I have aged they have darkened and 'age spots' have appeared.
I was keen to try the ESK products and see if they would soften the pigmentation. I
noticed a reduction in pigmentation after using the ESK Enlighten Gold (with daily
sunscreen) for approx 6 months and this has been improved by adding the Ultimate Gold
in the evening.
I didn't expect fast results based on my history and from explanations in the articles on
pigmentation written by Dr Ginni.
I'm very happy with the results so far, I love the products and also learning of the science
behind them.
Congratulations on a fabulous science backed Australian-made product!"

"I found the whole range very easy to use and great quality. I found the number 3 worked really well for me. I have used similar products in other high end ranges with the same UV properties and your number 3 impressed me. I couldn’t feel it on my face and it sat perfectly under my make up all day. Wonderful as a primer."

"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."

"Have been using the Pigmentation Kit for 4 weeks now and have noticed an improvement in my overall skin tone, my hyperpigmentation has lightened a little (in the smaller spots) and I feel that I can go out without makeup on (maybe some blush and mascara). Very happy that the kit didn't react with my skin as I have sensitive skin. My skin feels more supple and smooth too. I cannot wait to see what another month or two brings with the kit!"

"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!"
