Most Helpful Positive

Love this product


My skin is prone to breaking out and mask-acne. This really helps to take out the redness and feels great on my skin.

Sadly Not For Me


I really wanted to love this serum. I persisted with it and tried going back to it several times. Ultimately, it just doesn't work for me. It has an overbearing lavender scent which makes my eyes water (despite keeping the product well away from my eyes). I also found that it causes my skin to break out. Whilst breakouts can be normal when adjusting to a retinol product, I have had better experiences with other products.

  3. Gentle


    verified purchaser
    This product is very gentle yet gives results. My skin is brighter and even. It won’t happen overnight but persevere. Lavender smell is strong but reminds me not to use close to eyes or use too much as it’s actually nice if you use pea size amount.

  6. One of the best


    I've used many retinols and this is one of the best. It sinks in nicely, doesn't irritate the skin and delivers results. Like all retinols, you need to give it time, but this retinol is gentle, but effective.
  7. Amazing Miracle in a Bottle


    verified purchaser
    Since using this product, I have experienced little to no breakouts (even when I've had sugar fest which tends to leave me with breakouts!). My beautician recommended this to me and I use this every second night. My skin has never looked brighter and clearer- friends have commented that I have the most glowy skin! You definitely need to wear sunscreen everyday when using this kind of product.

  8. Great for sensitive skin


    I thought I couldn’t use retinol as it was too drying - this isn’t, as long as you start slow. My sun spots are lighter, but it did does require patience as it took a long time to see results.
  9. Gentle but effective retinol.


    Loveeee. Such a high quality product with a unique delivery system. This is gentle enough for my dry, sensitive skin but still effective. I started using this once per week and built up very slowly - now my skin loves it. After two bottles this has absolutely lessened my pigmentation and brightened my skin. A crucial part of my routine!
  10. Worth every cent!


    My facialist put me onto this and I'm hooked. Have been using retinols for years but with this one I've seen the most dramatic difference in my fine lines. I also love the smell and a little goes a long way. I have sensitive skin and some retinols have caused a reaction for me, but I have never reacted to this one! Love it.
  11. Awesome results


    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
  12. Retinol for sensitive skin


    I purchased this serum to incorporate retinol into my skincare routine. I only use it once or twice a week as I have very sensitive skin. I love the smell, consistency and the packaging.

    Results-wise I am not 100% sure if I love it yet, I have only been using for a few months. I have not seen instant results but I will continue to use and test out.

  13. 1 year review using Serum 16


    I have been using serum 16 for the last twelve months. Prior to using serum 16 I have never used any retinol products so I was expecting the skin tingling and potentially the dry skin that is often reported with using retinol products. I have sensitive skin too so I was expecting this to occur and did not experience any tingling. I did notice renewed skin every now and then, but I also found the n...

  14. great intro to retinol


    I really liked this serum. Its colour is a little yellow and it has an odd smell that settles quickly. The serum goes on smoothly and feels hydrating. It was gentle enough for daily use after a slow introduction. I noticed brighter skin and improvement in breakout prone areas such as my chain and around mouth. I have not repurchased as I am hoping for something slightly stronger
  15. Didn’t work for me


    I don’t really like this, I found it made no difference to my skin and to be honest I wasn’t even sure what it’s supposed to do! It had no affect what so ever. Disappointed considering the price I paid
  16. Won’t Re-Order


    I had such high hopes for this product, having seen it recommended often. Sadly, it didn’t work for me. I can honestly say I didn’t notice any positive change in the quality of my skin. Such a let down.
  17. Not sure


    I’m not sure how I feel about this product.. I was hoping I’d see some major changes in my skin after using it but I haven’t really :(
  18. My nightly saviour


    This is my 3rd bottle, I’ve tried other retinol products but can’t go past this one. It is non irritating and leaves my skin feeling hydrated and soft.
  19. Amazing


    Nice easy to use serum. Have noticed a reduction in my fine lines and my skin tone appears more even. would highly recommend. Does not irritate or leave the skin feeling tight.
  20. 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!
  21. First time retinol user - definitely recommend


    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.
  22. Cant' go past it


    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!
  23. Great intro to retinol


    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.
  24. redness reduced


    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
  25. Could be your 1st retinol


    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.
  26. Sensitive skin can tolerate this


    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...

  27. Great retinol


    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...

  28. Must have!


    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...

  29. My go to


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


    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!
  31. Quite effective


    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.
  32. Not sure


    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
  33. Good entry retinol


    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.
  34. Good beginner retinol


    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.
  35. Found a permanent place in my daily routine!


    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.
  36. Unsure


    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 :(
  37. Cosmedix Serum 16 Featuring LG-Retinex


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


    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.
  39. The only one that gives noticeable results


    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...

  40. Fast results!


    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...

  41. Superstar Serum!


    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...

  42. I like it


    I really like this serum, very hydrating
  43. No 1 product


    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
  44. Better than prescription-strength.


    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.
  45. Effective and non irritating


    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
  46. Life Changing


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


    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.
  48. Simple yet effective


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


    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.
  50. My go to retinol


    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.
  51. Amazing


    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...

  52. It gives results


    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.
  53. Overnight wonder (long term)


    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.
  54. Good results, non irritating


    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.
  55. Long term gains, short term pain


    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...

    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.
  57. Best product I've used


    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.
  58. Love it!


    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.
  59. The perfect retinol serum for sensitised or reactive skin


    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.

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


    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.
