Line Smoothing Serum features Paracress extract (Gatuline Expression) a clinically tested active to smooth expression lines and wrinkles.  Works similarly to well known injectables but is safe, non-toxic and pain free.

This serum is gel based and rapidly asborbed, and can be used by all skin types.

This product is receiving rave reviews: "I received a sample of this product and gave it to my mum to try. It absorbed quickly, and immediately her skin tightened and wrinkles smoothed. The best thing was that it didn't irritate her skin or eyes, unlike other products she has tried. It ticks all the boxes: non-irritant, Aussie made, organic, cruelty free, palm oil free, vegan and actually works! " - Kim

  3. Amazing Review by Rebekha
    Average Rating

    First I have to say this is one of the fastest absorbing serum I have tried as well as the fact that it doesn’t leave behind any residue making it ideal to apply a moisturiser straight away.

    I saw results in a few days and it did help fill out fine lines and firm the skin around the eye area. My skin looks and feels a lot smoother.

  6. Just lovely and lightweight Review by Annie
    Average Rating

    This serum is lovely. I also use it around my other fine lines and wrinkles and it is very lightweight and firming. It works beautifully with all my other sensitive products and does not inflame or irritate my rosacea. (Posted on 5/10/2015)

    I first came across this product via another site while looking for honest to goodness health & beauty products. I bought the line smoothing serum and i loved it from the very first application. It lasts me several months & i just took advantage of the buy 1 get 1 free offer during September....WOW, what a great offer for such a beautiful product.

    Very happy with the serum & i am looking forward to trying other products.

    Also very happy with my shopping experience with ZK'in and the emails come in at just the right time for that gentle little reminder not, every day :)

    Thanks again

  8. Complete convert to this incredible product Review by Sandy
    Average Rating

    I received a free sample of this product and after I tried it immediately bought it. It's much more than an eye serum and is working wonders on my newly emerged forehead frown lines. A tiny amount goes a long, long way and it is light and easily absorbed. I'm not sure how I managed without it! (Posted on 1/09/2015)

  9. a little goes a long way Review by Deb
    Average Rating

    I have been using this product since May 2015. From the first use I felt it tighten the skin around my eyes but still leave it nourished. At 42 I don't look my age and Zk'in is helping to keep my youthful appearance longer and it feels fabulous, is cruelty free, vegan and organic!!
    I recommend this and the other Zk'in products to anyone with oil combination skin.
    Love it! (Posted on 29/08/2015)

  10. love it Review by Tati
    Average Rating

    I bought this to use as an eye cream, but found it to be much more than just that. I use a very light amount all over my face before my daily moisturizer as it tightens my pores and works beautifully as a base. My skin looks much fresher and younger all day thanks to this product!

    After receiving a sample of this, I ordered a sample of the whole range and have since ordered the serum in full size. I love the smell and how fresh my skin feels after application. It is not greasy, absorbs quickly and my skin looks so much better. A beautiful product, have been recommending it to my friends :) (Posted on 27/04/2015)

    I could feel something happening as soon as I applied this product. I also use this around the lines I started getting around my mouth, and noticed a big difference in my skin's appearance. I use this day and night. Not sure what I would do without it now! (Posted on 22/04/2015)

  14. Promising Review by Cath
    Average Rating

    The only reason I am giving it 4 stars only is because I have only tried the sample and not used it sufficiently yet. But I liked the feel of it enough to order myself the full size. I am looking forward to the results. Love the fact that am supporting an Australian clean product. (Posted on 7/04/2015)

  15. Great results and product! Review by Abla
    Average Rating

    I purchased a sample of the Line Smoothing Serum and I noticed results instantly. My fine lines around my eyes and forehead tightened and smoothed straight away! I purchased the Serum for my mum who has puffy eyes and has tried a wide range of products on the market, but this was the only product that worked instantly. We both look forward to the long term results. (Posted on 6/04/2015)

    I purchased this after receiving a trial product as I wanted to try it out on a longer term basis. When I use it I notice an immediate tightening effect on the sensitive under eye skin and it keeps my skin well hydrated. A really wonderful product. (Posted on 17/01/2015)

Product Faqs

Ask a Question

  • My lips are starting to have lines. When wearing bright lipstick the lipstick bleeds which is awful. Will this product help diminish the lines? Marian, Canada.

    Hi Marion, you certainly can use zk'in Line Smoothing Serum for lip lines.    The serum can be used on the forehead, crows feet, nasal folds, lip lines and marionette laugh lines.    Just please don't use it as a lip balm.   We suggest you apply the serum to lip lines with a cotton tip, to help direct its application.  Some other tips to help with lip lines: ensure your lips are hydrated before applying your lipstick, recommend applying some whipped shea butter overnight as this will help plump and hydrate the lips.  In the morning apply the zk'in Line Smoothing Serum followed by a lip liner as this will also help to minimise the lip colour bleeding.  Always opt for matte lipsticks, not gloss as gloss tends to bleed more, matte will stay in place better.

    How much this was helpful

  • Hi,I have sensitive skin and cannot use most eye creams because they leave me with little bumps/pimples underneath my eyes. Just wondering if you think this serum could work for me?Thanks very much

    zk'in Line Smoothing Serum has been dermatologically tested and proven non irritant to sensitive skin types so we can definitely recommend for you!  Also, the serum is gel based so it doesn't cause milia (the tiny white bumps that can appear under the eye) the way thicker creams can.  This means you can use the serum on delicate skin around and under the eye.  Application tip - apply a drop of the serum to your ring finger and gently pat into delicate skin - a little goes a long way.
