Most Helpful Positive

Soft, clear skin

Joy

Great intro to retinol. Best one I’ve used so far. It goes on light and absorbs straight away. Only tingles for about 10 seconds. I layer a moisturiser over this and in the morning, my skin is so smooth, glowing and clear. Going to try refine next which is the next level up in this range now I’ve been using this for about a year. A bottle lasts ages so a good investment.

Most Helpful Criticism

Not my favourite

Lachlan

Very pricey but it’s decent... I like this but probably wouldn’t repurchase it unfortunately.

  2. Great introduction to retinol.

    Shani

    After seeing a skincare specialist this was the first retinol product I ever purchased. I do not have sensitive skin but it definitely took a little while for my skin to adjust to this product. For the first week or two the product made my skin a little dry, red and flaky but after a month or two I did notice my skin was smoother and plumper. I have now moved onto a stronger more expensive Cosmedix retinol product but I actually prefer this one as it does not make my skin feel as sensitive. It is definitely a pricey retinol product but my tube lasted approximately six months.
  3. Perfect beginner retinol

    CarleyP

    I had never used a retinol before, but wanted to give one a go. Mind you, one of the reasons I hadn’t used one is because I was scared for some reason. I think all the stories of people over using it and “burning their faces off” scared me off. After doing some research I settled on Cosmedix Define and I am so happy I did. My skin has handled it well and I haven’t had any trouble with it.
  4. Great for Smooth Skin

    McLemon

    Cosmedix Define makes my skin feel as smooth as a baby's bottom. It feels nice to apply and is not irritating to the skin. This product provides retinol without the dry and flaking skin that can sometimes come with it.
  5. Not my favourite

    Very pricey but it’s decent... I like this but probably wouldn’t repurchase it unfortunately.
  6. I don’t like it

    Bre

    I’m not liking this, I haven’t noticed any improvement in my skin and I also really don’t like the smell. It’s quite unpleasant
  7. Intro to Retinol

    Jo

    I bought this product as my first introduction to Retinol. I feel it does a good job, I love the smell of it and how moisturizing it is. I'm ready to go up to Refine now and hopefully so better results.
  8. Smoothed my skin quickly

    Sally

    I have been using this twice a week and have noticed my skin changing already. My chin area suffers from hormonal breakouts and the skin can be quite bumpy. The area is smoothing out already after only two weeks of use. Would definitely recommend!
  9. Great so far

    Grace

    Have only been using this product for a week but i really like the feel of this serum and wake up with noticeably brighter and clearer skin.
  10. Really Works

    Vanessa

    I love this product, it has improved my skin tone and my skin feels smoother. I find that my moisturiser absorbs better and makeup goes on more evenly when I use this.
  11. Lovely

    Lachlan

    This is so great on the skin. I really really like it although it kind of has a weird scent. Really great product! Loving it.
  12. Feels amazing

    sara

    I have dry sensitive skin and have tried a lot of products for hormonal acne which comes up around my chin and forehead.
    It’s not super bad but I feel like my skin gets bumpy and yucky.
    I have been using this cream on and off sometimes two or three days in a row then stop for a couple of days. I use over it the Avene Triacneal expert cream at night.
    My skin doesn’t react to this combination and feels amazing in the morning and clearer with fewer bumps.
    Would definitely recommend for dry sensitive skin like mine!
    The smell is a bit weird but doesn’t matter in the long run
  13. Nice texture

    Mel

    I've tried a few retinols. This one feels like a quality moisturiser as well, doesn't dry out my skin like some others. I get a little flaky/ dry skin a day or two after using it, but nothing that's not easily fixed. Only downside is the price, it's quite expensive for what it is.
  14. Cosmedix Define Resurfacing Treatment

    Zhaowei

    Very light but very effective the same time,really moisture my skin,lovely under make up.
  15. Early days but feels nice

    Hayley

    I have been using this product twice a week for a couple of weeks now. It goes on nicely and you don't need to use a lot, which is helpful given the price. I have dry sensitive skin but seem to react well to it, and my skin feels lovely and hydrated in the morning after using it. Look forward to seeing how it goes over the next few weeks.
  16. Effective retinal treatment

    roslyn

    I use this once a week. I don't think you would need more, especially if you are using the other wonderful Cosmedix products.
  17. Best Vitamin A I've Come Across

    Jacqui

    This is the best Vitamin A/Retinol I've ever used. A lot stronger than my usual aspect one but the results are so worth it. Worth the buy.
  18. Serious improvement to skin texture

    Jordi

    My beauty therapist recommended this serum for night time to help with skin texture. I have generally clear skin that is slightly dry, but suffer from hormonal acne on the chin and slightly bumpy skin texture on the jaw line. I have introduced this product every second night for a week (as per therapist's instructions) and have already noticed significant improvement in my jaw line texture. Very happy with this product.
  19. Smells awful!

    Emily

    This cream leaves my skin smooth and it feels very rich, but I can’t stand the smell of it! I’m not sure if they all smell this way or if I have a bad batch but it’s so gross. It puts me off using it
  20. Great product

    Jennifer

    I have fairly sensitive skin which is quite dry, this product is creamy in texture and feels hydrating when it’s put on, it works overnight so in the morning your skin feels amazing! So soft, clear and even. I was definately suprised!
  21. My skin looks great

    Emma

    This leaves my skin feeling so smooth. I use this only at nighttime and when I wake up my skin looks clear and bright and glowy. Would definitely recommend
  22. Good quality retinol

    Sarah

    I started using Define as recommended by my dermatologist and went from sample size to two bottles of Define later. Don't get put off by the price as the large tube lasted me over 6 months and you definitely get your money's worth. A little goes a long way. It comes out like a thick cream and is easily spread over your entire face. I found using define my skin was more plump and lines in my forehead reduced.
    However, being quite a potent retinol cream do not apply more than recommended otherwise your skin may react and what happened to me began to develop milia from too much retinol use. Overall a good product from a good quality brand and still use but use every second night.
  23. Noticeable difference to skin

    Bee

    Been using a generous sized sample of this, a little goes a long way. This is a relatively thick cream, it glides on the skin (almost like a primer) spreads easily and dries down to a weight loss smooth finish. I only use at nights and have noticed my skin overall looking better. Clearer, tighter, more refined. Will continue with my sample then will purchase the full sized
  24. Best retinol !

    Lauren

    I have used this product for over two years and it is fantastic. My skin is a lot smother when I apply every second night, and I have noticed the difference when I have stopped using it temporarily. Highly recommend. Tube lasted me almost 12 months.
  25. Amazing!

    SOPHIE

    After a few recommendations of this I thought I’d give it a go. It definitely didn’t disappoint my skin had more clarity and smoothness after one night it also felt moisturised. I’ve been using it every few days to build up a tolerance to the retinol, no flaking so far like I thought I might. I can’t believe how quickly I’ve fallen for this product and how much of a difference it’s made in my skin in such a short time. LOVE.
  26. Worth the dollars

    Kathryn

    This is the second time I have purchased this product, I used another brand of vitamin A and just don't think it worked as well. I started using this one night a week and then after a few months went to two nights and now use it four nights a week. I have found it to be the best anti-ageing product I have ever used, it helps with skin texture and I do believe that is has slowed down any fine lines.
  27. Gentle retinol product

    Janelle

    I really like this product because it is gentle and effective, and a little goes a long way so for the price it is worth it. I add it to my night time routine a couple of nights a week and I've noticed a difference in the smoothness and clarity of my skin.
  28. Heaven

    MT

    I bought this product as my facialist recommended it. After using it my skin looks clearer and hydrated. It contains products that are highly recommended for anti aging products.
  29. Amazing introduction to retinol!

    deanna

    I had never used a retinol before and this baby left my skin so soft and supple straight away. I’d put it on before applying moisturiser before bed and I fell in love. It introduced me to the cosmedix brand and I could not be happier.
  30. Brilliant

    deanna

    I use define every second night and my skin adores it! Such a gentle exfoliation whilst I sleep and I mix it with creme de la mer. Amazing product
  31. Great product

    Meg

    I was recommended this by my nurse practitioner for my acne. It has been really great. Steep price, but you only need a little so it will last a while. Great investment for anti aging too!
  32. Results delivered!

    Esther

    A very potent product! START OFF SLOWLY and you will see results! :)

    I have combination skin, frequent breakouts and some dryness and this Resurfacing Treatment really delivered the results I desired.... clearer skin without flakiness! :)

    I started off with only using Define twice per week and moving up slowly from there :) You definitely need to use a sunscreen during the day when using this product!!

    Read the instructions carefully and a little really goes a long way as it is a strong Resurfacing Treatment! :)

    The tube has lasted me months so far, well worth the investment!
  33. Lovely

    Anita

    This has been so so lovely to use. I feel like I can already see a difference just after a week.
  34. it works

    Abbey

    Skin type: Oily/combination

    This product didn't disappoint, noticeable results after a few uses.
  35. Love it!

    Ash

    I was recommended this product by my beauty thearapist and it does not disappoint! You feel the acids tingling away once you put it on but that doesn’t last long. It’s a very nice textured cream that feels really lovely on the skin. I have sensitive skin and it hasn’t been me break out at all. I haven’t been using it long enough to tell if it’s hindering the age process but I’m very happy with my purchase and would highly recommend!
  36. Game changer

    Ms Zig

    I was recommended this product by my beauty therapist I really like it, does exactly what it’s says also evens my skin tone and softens my fine lines.
  37. Trusted brand for a step by step treatment

    KJ

    I'm 46 years old and had recently decided to use a Retinol product in conjunction with advice from my Cosmetologist. I had thoroughly researched the how's, why's and usage of Retinol and came to understand that this was not to be a product to be used without caution!

    I have used the Cosmedix brand for many years now and have been very happy with the results. Not to mention that Cosmedix is a highly trusted and long established brand using only the purest of ingredients.

    Cosmedix uses a step by step program that is great to follow for a Retinol regeme:

    1. Define
    2. Refine 4% (plus Defy if required)
    3. Refine 8% (plus Defy if required)
    4. Serum 16

    I've been very happy with the results thus far in using the Define and Refine 4% with the results being as expected from the product description and for the usage of Retinol results in general.

    I would safely & highly recommend this product!
  38. Use this product for all the right anti aging ingredients

    Lisa

    I bought this product as my facialist recommended it. After using it my skin looks clearer and hydrated. It contains products that are highly recommended for anti aging products. Being a product that specialists use tells me it’s unlikely to contain filler products as many brands do. I use it with a dermal roller for even better results
  39. Good gentle retinol product

    Lindsay

    I started using this product on the recommendation of my facialist when my skin was irritated and peeling from retinol use. She explained that the retinol in this product is encapsulated and therefore less irritating than conventional retinol products. This product has a nice cream-like consistency. I use it after cleansing at night and find that I don’t need to use moisturiser over the top. It tingles a bit on application (probably the effect of the acids) but hasn’t caused me any irritation. I would highly recommend this to someone with sensitive skin who wants to start using retinol, or to anyone who wants an even, glowy complexion.
  40. Greal when your main concern is texture

    Katherine

    Define is a true hero product and it's a great one when you are looking for only one product to do the work of two or three producto in your nighttime routine. It contains several different alpha hydroxy acids combined with Cosmedix's patented AGP retinal complex (an intelligent encapsulation technology which allows skin to effectively use the retinol with minimal irritation). The result is skin that starts to feel smoother in one use. Obviously results will improve over time. A couple of useful tips: personally I wouldnt stay on Define forever. Cosmedix has designed their range so you can progress through the products as your skin improves in quality and is therefore able to tolerate higher concentrations. I'd use one or two tubes of Define and then move into Refine which is a stronger retinol with no AHAs. Also, MAKE SURE YOU WEAR SUNSCREEN EVERY SINGLE DAY WHEN USING DEFINE. The ingredients really increase your risk of sunburn.
  41. AMAZING!!!

    Magz

    This is a must have product, you will see a difference from the first time you use it.
  42. Amazing, works fast!

    Lauren

    I was given a sample of this product by my beauty therapist because my skin is sensitive and I react to a lot of products. The sample worked so well I had to buy it!
    Already, over 3 nights it has changed my skin so much- more refined, less congested, has healed my pimples, more even skin tone and I’m now barley needing to wear make up. FOr a gal that always covers up that’s amazing.
    I’m using this to help my skin prewedding and I could not be happier nor more relieved at how well it works. I’ve tried a lot in the past!
  43. AMAZING!

    Steph

    The difference in my skin since using this product (together with the Aspect Extreme B17 serum) is hands down amazing!!!! I have always struggled with blackheads, whiteheads and pimples, even in my 30’s and have tried many brands without any result. I highly recommend this product.
  44. Holy Grail!

    Lauren

    This is my absolute favourite night time treatment. I use a couple of times a week after cleansing and wake with wonderfully smooth, clear skin. It is a little expensive, but a little definitely goes a long way - one tube lasts me around 9-10 months.
    I use this on recommendation from my skin therapist.
  45. Great product, but use caution

    Evie

    I love this product, I use it every second night, and it's great for spot treatment too. Having said that, I did have to build up to being able to use it this often as your skin has to adjust, and I did so under the instruction and guidance of my dermatologist.
    This product leaves skin smooth and has a lovely texture, but can be drying, and create redness if overused.
