C Forte
C Forte Morning Serum is packed with 16% L-ascorbic acid, the purest form of Vitamin C, combined with vitamin E and ferulic acid for maximum results. Vitamin C (Ascorbic Acid) is an anti-oxidant helping neutralise free radicals (associated with exposure to the sun). The result? A brighter, firmer, plumper looking skin with fewer fine lines apparent and a more even skin tone. Formulated at the ideal pH (2.5-3.5) and housed in airless, opaque packaging, C Forte ensures stability and effectiveness, delivering radiant skin with every use.
Featuring;
- Evidence based ingredients and formulations for superior efficacy.
- Potent skin brightening ingredients
- A plumper, more hydrated and even toned skin.
Note: C Forte can exacerbate acne and may be too strong for irritable skin.

ESK Benefits
Do not use if you have sensitive or acne prone skin. All other skin types are suitable!
L-Ascorbic Acid
Also known as Vitamin C, L-Ascorbic Acid (Vitamin C) is a well-studied antioxidant that helps improve the appearance of uneven skin tone and supports smoother-looking skin.
Vitamin E (α-Tocopherol)
Vitamin E is a well-studied antioxidant commonly used in skincare to help support an even-looking skin tone and maintain the appearance of healthy skin. It is often included in formulations alongside other ingredients, such as Vitamin C, for complementary benefits.
Ferulic Acid
Ferulic acid’s emerging evidence suggests it can improve the effectiveness of Vitamin C and help to reduce the appearance of fine lines and wrinkles.
Apply 1 – 2 pumps to fingertips and apply to face after cleansing in the morning. Also for use on décolletage, back of hands and forearms.
Brighten Your Skin
A potent antioxidant serum that supports the skin’s appearance and hydration.
The antioxidant vitamins C (L-Ascorbic Acid – 16%), E (Tocopherol – 1%) and Ferulic Acid (0.5%) are combined in a stable formulation designed to maintain the integrity of the ingredients and support the skin’s natural moisture balance. Vitamin E and Ferulic Acid help stabilise Vitamin C, preserving its effectiveness over time. Some users may notice a slight scent from Ferulic Acid, which fades quickly after application.
Full Size – 50ml (lasts 3–4 months)

Frequently Asked Questions
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.
No, just apply in the morning after cleansing.
C Forte is not recommended for sensitive or acne-prone skin, as the high concentration of L-Ascorbic Acid and its low pH can be too stimulating for reactive skin and may exacerbate breakouts. Those who only get occasional hormonal pimples may still be able to use it by applying it while avoiding blemish-prone areas. For sensitive skin, C Serum Lite is the gentler alternative.
Generally, we do not recommend oil-based products like our Vitamin C for oily or hormonal skin. However, if you only get the occasional break-out and want to incorporate Vitamin C into your regime, simply apply avoiding problematic areas.
Some users notice a slight scent from the Ferulic Acid, which is a natural characteristic of this ingredient. It fades quickly after application and is not a sign of spoilage.

"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.

"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!"

"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 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!"

"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 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've been using the Pigmentation Kit for last 4 weeks and I'm really pleased with the fading of the dark spots so far and look forward to seeing the results after 3-4 months use. The AM/PM process is easy to follow and not time consuming. My favourite product is the Calming Cleanse which leaves my skin feeling soft and fresh. Each product I apply after the cleanse glides on and feels amazing. I'm so very happy I decided to purchase the Kit and can highly recommend if you want your skin to feel smooth, target some problem areas and look younger then definitely give ESK skincare a go. My heartfelt thanks to the Team at ESK for your support and for sending through interesting additional evidence based skincare updates through email."

"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'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."
