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: 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,
