Good gentle retinol product - 16-04-2018 by

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.

Greal when your main concern is texture - 03-04-2018 by

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.

AMAZING!!! - 06-03-2018 by

This is a must have product, you will see a difference from the first time you use it.

Amazing, works fast! - 25-02-2018 by

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!

AMAZING! - 27-11-2017 by

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.

Holy Grail! - 12-10-2017 by

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.

Great product, but use caution - 28-08-2017 by

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.

Q & A
1 Question Ask a question
  • From Cosmedix Define Resurfacing Treatment at 20/04/161:42 PM
    • Q: How often should I use Define? I have sun-damaged skin which is also quite old.
    • A: Hi there,

      Thanks for your product question. It really depends on what products you're currently using! If you'd like a skincare recommendation, please fill out this form:

      What is recommended for this product is to use it 2 - 4 times a week, at night, on freshly washed skin. If this is your first time using a Vitamin A product, you will need to work up to it - start with once a week at first, for the first four weeks, then increase usage. If you find you feel dry or tight after application, pop a moisturiser on top, and then go to bed.

      If you have any further questions, please don't hesitate to contact our customer service team at

      Kind Regards,
