great results

You only need a drop in the AM & PM to see rapid clearing of skin & a reduction in lines. It's good to know that this product is REAL & works!

I really wanted to be wowed by this product but I feel a little underwhelmed by it. I haven’t noticed any changes in my skin at all. Maybe it’s more of a long term thing? I’m not sure but I’m a little cut up about it :(

  2. First time retinol user - definitely recommend

    Lauren

    verified purchaser
    This was my first retinol product i used on my skin, i noticed a different pretty quickly with how plump it makes my skin feel and helping my fine lines even after using it sparingly/every few days, will definitely purchase again.
  3. Cant' go past it

    Clauds

    verified purchaser
    I really love this serum. I have tried may other vitamin A serums but keep going back to this one. It is no irritating, very hydrating and hopefully will keep my skin youthful in the years to come!
  4. Great intro to retinol

    Karen

    verified purchaser
    This was the first retinol serum I ever used, and it was a lovely gentle introduction into my routine. I noticed an improvement in my congestion, brightness and plumpness of my skin within a week. Highly recommend for first time retinol users.
  5. redness reduced

    s

    helps reduce my rosacea and make my skin appear more unified in tone. i love the luminous smoothing and plumping effect that it gives my skin
  6. Could be your 1st retinol

    willow

    verified purchaser
    Everyone should begin to use retinol products as young as possible. I'm 22 and I have read numerous recommendations and finally choose it as my 1st retinol. So happy to see it works quickly on my skin in 3 days. My skin texture is so smooth!

    And it has really perfect ingredients like Hamamelis Virginiana (Witch Hazel) Water, nice smell.
  7. Sensitive skin can tolerate this

    Vic

    verified purchaser
    Sensitive skin can tolerate this product. I suffer rosacea and allergies and this product is one of the few that doesn't irritate my skin. I have gone from 2 a week to 2 days on 1 day off. And my skin is starting to improve after 4 weeks I can notice less pigment on my forehead. I have started to introduce it near my eyes and so far it's working well without irritation. There are other stronger pr...

  8. Great retinol

    Laura

    verified purchaser
    I've been using this retinol for about two years now after I was recommended it at Melanie Grant's clinic in Double Bay (Sydney). This retinol never irritated my skin (which I know can happen to some people with retinols). It goes on smoothly, and absorbs into my skin really well.

    The packaging is elegant, and the pump size that it dispenses is quite good (I usually need two or three...

  9. Must have!

    Robyn

    Incredible product which for the first time in years leases me with normal feeling and texture skin that’s not always clogged and covered in bad acne.

    Even if a few spots appear the skin texture is so lovely and healthy looking overall that they barely stand out. They also shrink overnight with this product. I love that it includes moisturising elements as I haven’t used a moisturiser...

    Claudia

    verified purchaser
    This is my nightly retinol, it has never irritated my sensitive skin and leaves it soft and hydrated.
  11. Great product

    Olivia

    This is really making my skin look a lot healthier as I’ve been using it over the past week or so. My skin is brighter and more even toned and my pores definitely look smaller after each use. Love this serum!
  12. Quite effective

    Samantha

    This is the first time I’ve bought this product after reading positive reviews. It’s fairly strong and effective so I’ll probably purchase again and would recommend to others.
  13. Not sure

    Bre

    I’ve been using this product and haven’t really noticed any difference in my skin. I’m 29 so my skin isn’t too bad but I did expect some change. I also don’t like the smell and the consistency is very thick. Would probably suit someone with older skin
  14. Good entry retinol

    LJ

    This was recommended to me by a skincare professional and really was the introduction to cosmeceuticals to me. I found it definitely delivered visible effect, and didn't irritate my skin. My skin feels brighter and more refreshed after having used a full bottle. I've now moved onto a higher strength retinol but I'd definitely recommend this as an entry level v A product.
  15. Good beginner retinol

    brenda

    This stuff is quite gentle so a good choice for beginners. But I run out of it quite quickly - a bottle lasts for about 3 months if you use 2-3 pumps nightly. Given that it's kinda pricey I would recommend getting a sample if you can to at least test it.
  16. Found a permanent place in my daily routine!

    Katty

    Since I started using this product I've noticed a change in the texture, how clear my skin is and the elasticity. It is now more hydrated than ever. Even my beauty therapist commented on how good it looks.

    Zhaowei

    This formula goes on smoothly, feeling face left moisturized, calmed, and smooth.
  19. One of my favs

    Lisa

    This is one of the best retinol's I've tried. It helps keep my skin really clear and the skin tonne much more even. Even after being a long time retinol user, I still noticed the impact that this had on my skin when going from an alternative brand of similar strength.
  20. The only one that gives noticeable results

    JardiB

    I love this for so many reasons. It has a high degree of potency and the sustained release formulation does not make my skin peel like other retinol products. Best of all it is very moisturising and smells so good. The only criticism is that it’s expensive, I used Cosmedix and the tried a neostrata retinol but it didn’t give me the same outcome. I noticed that my skin look lacklustre after not usi...

  21. Fast results!

    Alisia

    I started using this product 2 weeks ago. After 3 nights I saw a huge difference in the texture, clarity and elasticity of my skin.
    Probably the fastest results I’ve experienced! I have sensitive skin and this retinol serum is gentle enough not to irritate or cause any redness/reaction. I’ve experienced some light dry flaking around my mouth but I’ve been using the product nightly - so perh...

  22. Superstar Serum!

    Hayley

    I’ve been using this serum for a little over a month now and I’m obsessed! Initially I used it every third night but am now using it every second night (alternating with overnight acids) and have had none of the usual teething problems (peeling, purging, irritation) that accompany the introduction of retinol. My skin tends to be on the dry side so I follow this with a ceramide cream and wake up to...

  23. No 1 product

    Dee

    No other product has had such a noticeably positive impact on my skin. Be sure to start slowly, as it is an active product. I have tried other products but keep coming back to this
  24. Better than prescription-strength.

    Jo

    I purchased this product after realising that my skin was fundamentally incompatible with prescription-strength tretinoin, which would cause significant peeling and a burning sensation irrespective of frequency. I've achieved better results with this product in a shorter period of time. It takes a few weeks but it's worth it. Fortunately, I didn't experience purging.
  25. Effective and non irritating

    Nicole

    Was recommended this by my esthetician and it had resulted in my skin looking clearer of pigmentation and overall fresher. It’s non irritating but really effective I’ve repurchased multiple times now
  26. Life Changing

    MT

    Was recommended this by my skincare therapist. Nice product. easy to use. Would recommend easing into daily use. Great amount of retionol in here
  27. I wish I had known about this product sooner

    KJ

    I have been using this product for around 1-2 months, I know it takes about 3 months of using retinol to actually see a real difference, however I can already see a huge difference to my skin - it feels smoother and I can see a reduction in pore size.
  28. Simple yet effective

    Larissa

    Was recommended this by my skincare therapist. Nice product. easy to use. Would recommend easing into daily use.
  29. Does the job

    Cat

    This definitely works as a powerful retinol treatment - in combination with dermal needling this has made a big difference to my pore size and skin texture! The fragrance does seem to sting my eyes a little but other than that it’s lovely to apply - a little goes a long way.
  30. My go to retinol

    Adeline

    I have been using this product for a number of years and I think it has been a great preventative and to keep my pigmentation under control. It’s gentle on skin and I use it every second night. I wake up feeling like my skin is smoother.
  31. Amazing

    Laura

    I’m furious at myself for waiting so long before buying this. It’s so good! Not going to lie, I was a little dismayed at the size of the bottle when it arrived, but I love it so much that I don’t even care anymore. It has made such a difference to the texture of my skin, and especially my pigmentation. My fine lines seem diminished, and everything just looks brighter. I was worried that such a hig...

  32. It gives results

    Abbey

    Skin type: Oily/combination

    I have been using this for about a month now and I can definitely see changes in my skins appearance, expensive but worth it for such a good serum.
  33. Overnight wonder (long term)

    Smiley

    I have dry sensitive skin and this product was recommended by my aesthetician/facialist. I use it in the night after I wash my face. When my skin is particularly dry, I use the serum and follow up with a moisturiser/mask. The serum has made my skin softer, clearer and reduced breakouts. I did not see results overnight, but definitely began seeing results in after 4-7 days of using it.
  34. Good results, non irritating

    Nicole

    I have sensitive skin and have tried several different retinol products before my racialist recommended this one to Me. My skin texture and evenness has improved a lot after using this for around 6 months (saw the smoothing benefits quite quickly). For reference I’m mid 20s with combo skin.
  35. Long term gains, short term pain

    Laura

    I have been using this for a year now. I have sensitive, rosacea prone skin and didn't think retinol products were possible for me. This works, but it was a pretty lengthy adaption process - a few months of my skin getting worse rather than better, and building up from every three nights to every night.

    Now, no problems, and really makes a difference to skin texture and fine lines, wi...

  36. LOVE LOVE LOVE

    KRISTEN

    This is my favourite night serum and has definately improved my skin tone. Also please that my complexion has evened out. I wouldn’t use during the day because of the sun sensitivity it can cause. Also feel like it’s made my skin softer after I use it.
  37. Best product I've used

    Victoria

    This is the most effective product I've used. It took a while for skin to tolerate it daily though but once you do if you back-up with C in the morning and B at night its fantastic. I've just turned 50 and I'm using it vigilantly. I have no reason to stop using this product.
  38. Love it!

    Paige

    I have used this serum for years and it remains one of my favourite products. It is great for sensitive users and keeps my skin hydrated in combination with a moisturiser as well. I alternate this every second night and use the Alpha H liquid gold on the other. My skin is clear and radiant. Very happy with the results.
  39. The perfect retinol serum for sensitised or reactive skin

    Katherine

    I love this product and have used several bottles of it, but I have also recommended it to plenty of people as well. It is a mild retinol which allows the user to enjoy the benefits of Vitamin A derivatives (eg rebuilding, strengthening, anti-ageing, antioxidant, repairing sun damage) without risking the inflammation of a full-on retinol serum or prescribed retinoid.

  40. Love this serum - works on my large pores and blemishes

    Courtney

    This was recommend by my facialist instead of the discontinued aspects one I was using.
    Works amazing one pump goes a long way.
    I was told to wet my fingers and work it onto my skin by patting gently and my skin always looks amazing the next day.
    Works on blemishes I put a small amount on them and but morning they are starting to disappear.
