I’ve only been using in my age spots for a couple of weeks so far but they seem to be fading. Hoping to see more improvements with continued use

Most Helpful Criticism

Didn't make a difference for me.

Janine

I have tried this serum a couple of times now for my pigmentation and I can tell it is quite powerful in its ingredients but it does not have that oomph in it. The bottle is quite small so that doesn't exactly help as well to give a 6 month trial. I am looking for not an overnight fix, but something at least you can tell after 4 weeks has made a visible difference and unfortunately this did not do that for me. I am trialing the Estee Lauder brightening serum now. I have trialled so many products and probably could of owed another house if I didn't waste so much money trying to find a product which works for me.
  1. No visible improvement after 1 bottle

    Momo

    I used it everyday until I finished the whole bottle and I didn’t see any improvements on my skin. Given the price tag, I’m now hesitant to give it a second chance.
  2. Powerful product

    Nicky133

    This is clearly a very powerful product, you can tell from its potency. I bought this to try and combat the melasma on my forehead, caused by my implanon implant. I broke out with itchy pimple-looking hives all over my forehead. The hives lasted for over one week and were impossible to conceal with make up due their protrusion. I still don't know what is in this that caused me to break out. I don'...

  5. Seems to work so far

    Maggie

    I have used this for about a month now and it would seem that my hyper-pigmentation is not getting worse. Will keep using to see if there is further fading; I think it's important to understand this is going to take time, but anything to stop further pigmentation is a plus. A lot sees to go a long way.
  6. Decent product, maybe too soon to see full results?

    Amanda

    I've been using this for a few months now to combat post-inflammatory hyperpigmentation, and while I haven't noticed any super drastic results I think it has helped to lessen the severity of the PIH that does appear after a breakout. This is great for people with oily/combo skin as it has a water-like texture that sinks into your skin almost immediately, and it spreads easily so you don't have to ...

    amazing serum to treat post-inflammatory hyperpigmentation.
  8. Brightening serum

    Leonie

    Only started using this serum for a few weeks so probably too soon for me to comment on whether it is effective for hyperpigmentation or not. However it definitely does help give a glowier complexion. It feels oil based rather than water based but is not heavy. I quite like the smell, it smells a bit like pineapple juice. It wears well under sunscreen and makeup and doesn't cause any pilling. Will...

  9. Interesting

    Jo

    This serum is quite different from serums I have used before. It has this kind of orange transparent colour and has a distinct smell which my partner doesn't like. I find that it moisturises quite well. I have used it for about a month now and haven't seen visible brightening effect, maybe potentially a little bit. After I finish the bottle, I will try something else instead of repurchasing.
  10. dark girl's dream

    Rey

    This is a MUST HAVE for particularly my dark girls who suffer from hyperpigmentation or just a generally uneven skin tone. I apply this to my face every day for 2 weeks before getting laser treatments to even the skin tone. It may be expensive, but a pea-sized amount goes a long way.
    Put onto cleansed, toned skin and just make sure to layer a moisturizer on top, because it can leave your sk...

  11. Effective!

    Olive

    This product is an effective and essential part of my skincare arsenal to tackle pigmentation on a daily basis. I have used this product consistently at night (before I apply moisturiser) over several months and have noticed a marked improvement with respect to existing pigmentation on my skin - it ticks the value-for-money box for me!

    Note: I have not used this product as a standalo...

  12. Lovely pigment inhibitor

    Allison

    I like this one because it stops new pigment but also works to repair old damage. I didn’t notice any crazy differences but felt lovely and my pigment hasn’t gotten worse.
  13. Best Brightener

    Hayley

    This serum is incredible. I have been using it for over a year and it's the only brightening product I've had success with. It helps reduce redness and pigmentation and I like that it's got active ingredients to help exfoliate. I like to add the Cosmedix Vitamin C Crystals for added brightening benefit.

  15. PIH Killer!

    Em

    I've been using this serum every morning for about 3 weeks now, and I'm not sure if its wishful thinking, but my post inflammatory pigmentation seems to be much lighter! I also had some nearly healed cystic acne when I started using this serum, and as far as I can tell those breakouts haven't left the usual red mark that lingers! Yes the serum has quite a strong and slightly unusual smell, but it ...

  16. The Best

    NJP

    This is the best, worth the cost. It improves how your skin looks immediately, sometimes it makes your skin a bit red for a few minutes but once you have put moisturiser on over the top your skin looks fresh, smooth, bright and healthy.
  17. So great

    Smaddi

    This product is fine if you are starting out on your even skin tone journey and building up to stronger products. Absorbs into the skin well and your hyaluronic serum or moisturiser goes over the top nicely.
  18. AMAZING

    Jessica

    Love this especially when mixed with Pure C crystals by Cosmedix
  19. Satified with puchase

    Rainbow

    it's light, i put on only at night before moisture
    Will continue to see the result.
  20. Really wanted to love

    Sammy

    I really wanted to love this one but it just wasn’t for my skin. After using a Cosmedix product filled routine, it just didn’t do anything for my skin after going through a bottle. I might try again to give it a go but it was pretty expensive and didn’t notice a noticeable difference .
  21. My Pigmentation fighter

    howen1

    The salon I was going regularly recommended this serum to be applied and prep my skin for next laser toning treatment. I don’t think it reduced the dark spots yet but hope this will fade gradually. So far I am happy with this serum.
  22. Brightening Product

    Bonnie

    I don't really like the dark colour but I can see it has brightened some spots on my face. Does not feel too oily on my skin, absorbs quickly.
  23. Good Quality Product

    Maddie

    Recommended this product for pigmentation and discolouration caused by pimples. Has definitely made my skin brighter and has helped reduce discolouration quicker. Does have a strong smell compared to other serums I use but that does not bother me. I will continue to use the product as part of my skincare routine.
  24. I like it, my partner hates it

    Francesca

    I thought this product was quite nice. It is supposed to brighten and assist with reducing the appearance of pigmentation.
    What I don’t really like- The product itself if quite dark in colour and the next morning when I cleanse and tone.... the colour residue seems to still be sitting on my skin as so much wipes off! It also smells quite strong and reminds me of wiping iodine all over my sk...

  25. Love love love

    Olivia

    I love this serum! I've been using it for 3 weeks and I couldn't be happier. My skin feels super hydrated, soft and glowy. I have acne scars around my chin and their colour isn't as dark as it once was. I love how you only need a little bit of product, a little goes a long way! Will be purchasing again.
  26. Absorbs into skin instantly

    Sherri

    This serum absorbs into your skin straight away. I have some stubborn pigmentation and have been using separate Vitamin C and Niacinamide serums each morning, and have tried combined serums, and my pigmentation is still there. I purchased this after a report done by an Adore team member on the best products to get rid of pigmentation and, it might be wishful thinking, but I feel like my pigmentati...

  27. Best skin brightening product

    Angelique

    This product makes my skin so much brighter and gets rid of pigmentation. I don’t know what I did without it. I just use it under my moisturiser before bed and it is amazing how well it works.
  28. It's okay

    Irene

    This serum felt nice for the first few applications, but doesn't really add much to my skin routine anymore. It also takes a while to seep into the skin.
  29. Good buy

    Alejandra

    As my first serum, I wanted to make sure to get an excellent product regardless of the price tag (which is considerable). I have been using it for a couple of months, and it does brighten your tone and leaves a nourished, healthy skin. However, as I have come across other serums now, I wouldn't repurchase this one as I found other brands to deliver more for half the price.

    I am my ...

  30. Potent but not gentle

    Sandee

    I like this product a lot but be careful in using a pea size amount. I found a smaller amount is about all my skin can handle and I have pretty tough skin.
  31. Waiting to see if it works long term

    Abel

    I've been trying to brighten a dark spot on my forehead with this. It seems to be making a bit of an improvement, but I'm waiting to see if it has lasting results.
  32. Cosmedix Simply Brilliant 24/7 Brightening Serum

    Zhaowei

    I bought this two weeks ago and I already started feeling difference in my skin. I love it. It’s so light on my skin and moisturise without oiliness.
  33. mild potency for price

    BeautyObsessed

    This product is fine if you are starting out on your even skin tone journey and building up to stronger products. If like me you have been using retinol, C, BHA's, lactic acid products for a long time, this doesn't pack enough punch to make a noticeable difference. Absorbs into the skin well and your hyaluronic serum or moisturiser goes over the top nicely.
  34. So far so good

    Em

    I recently purchased this product for the first time. I do think its starting to make a change to my skin, but really it is too early to tell. Very strong citrus smell, but product goes on well and is easily absorbed.
  35. Dont love it

    Abbey

    I'm generally a big fan of Cosmedix, but this just hasn't done it for me. I have quite a few active products on the go, so this one might just get lost in the mix, but unlike my retinol or vit b and c products, if I don't use this, I can't see the difference like with the others.
  36. Amazing

    Margaret

    This product is the most amazing product you can use it makes your face feel soft and bright.
  37. Still waiting to see results

    Kate

    I've been using this product religiously to treat my melasma and have noticed no obvious difference to my skin tone at all. It doesn't smell great but isn't unpleasant to apply. As it's so expensive I'll use the remainder of the bottle but won't be buying it again unless some miracle occurs
  38. Pigment reduced

    Sarah

    I started using Simply Brilliant when I first made the switch to cosmeceutical skin care in order to target pigmentation. I began using Simply Brilliant in conjunction with a good moisturiser/ sunscreen and took photos to see the change. Overtime Simply Brilliant has reduced the freckles/ pigment on my face, therefore brightening my complexion and making me one very happy customer. I've gone throu...

  39. Not worth it for me

    Hayley

    I used about half a bottle of this and I gave up. I didn’t see any difference in my skin and I used it religiously am and pm. I can normally get past bad product smells but this I hated. For the price and big claims I wanted better results.
  40. Brightens!

    Sami

    This product does exactly what it says it will. I noticed a substantial difference in my skin upon immediate use. Although a bit pricey, i believe it's worth it.
  41. LOVE

    I have melasma, post inflammatory pigmentation and generally uneven skin. This is the first product that had actually made a noticeable difference in my melasma after a month. I’ve used many other products and this is the only one that has ever made a difference.

    Riley

    I have hormonal acne redness around my chin, and this product was recommended to me and I'm happy I purchased.

    I'm using this product morning and night and I've noticed my skin has a clearer and brighter complexion. It sits comfortably on the skin and doesn't feel irritating at all (which I was worried about for its stronger properties).

  44. Ok. But can live without it.

    Lisa

    My skin can usually tolerate a lot, but I find this can aggravate my skin a little with prolonged use. Without regular use I'm not sure I'm getting full benefits. I'm a big fan of cosmedix generally but I don't think this one is for me.
  45. did not fade dark spot

    kat

    I used it for 2 months or more every day and it didn't help fade my dark spot at all. it also didn't help to brighten my skin either.
  46. Brighter and clearer

    sloanbeauty

    This product has definitely made my skin look brighter and clearer with a more glossy and healthy appearance. I can't say pigmentation spots have significantly lightened but the overall glow of the skin has helped to probably distract a bit more from them. It is not an overly sticky formula so has been nice to use day and night. I am enjoying this product and will likely venture into Cosmedix othe...

    Tiny307

    I've been using this product for a couple of weeks now. My skin has smoothed out due to the chemical exfoliants and perhaps a lightening of the pigmentation but am waiting to give it the final ok as skin takes a good month to turn over properly. It has been a warm summer and have noticed an increase in my pigmentation so I ordered this and use it with a Vit C powder mixed in. I like the ease of ap...

    Laura

    Have been using this product for 1.5 months now, and haven't seen a huge difference in my pigmentation, have taken before photos to compare. It does make the rest of my skin feel nice though. First time I used it my skin went bright red, monitored for a while and it slowly went away, only after the first use though.
  50. Works wonders

    Kate

    I have had really bad acne scarring and this cosmetic product has made my skin almost pigment free. I can’t even see any scarring anymore! It doesn’t dry my skin out and works a treat. Definite yes!
  51. skin is amazing and pigments lightened

    aksa

    I have been using this product for 2 months now and my skin is the best it has ever been. It is brighter and pigments lighter. I have recommended/ forced two friends to buy this and they have similar results. This is a definite must buy and re buy. I hope it works as good for you as it has for me
  52. Great product

    Gabrielle

    I am late 20s - slightly oil skin, uneven skin tone. This has been a great little serum I have used each night. It hasn't blown me away but it's effective and clears up my skin
  53. I’m impressed

    Marteen

    At 60 years young my skin has been subjected to the sun I was sceptical but wanted to de-age pigmentation. I took photos before and compared them 2 weeks later. Huge difference. I Only use at night. My daughter commented on how well I look told her what I was using,showed her the before and after and was amazed.
  54. Actually does what it promises

    SOnia

    After a few applications this product has actually lightened my pigmentation. I’m really pleased with the results so far. Well-worth the investment.

    Kathlyn

    Still in early stages of use but like the feel of this product on my skin and does appear to be lightening the pigmentation on my skin. Hope this keeps going and looking forward to success.
  56. Helps keep pigments at bay!

    Wendy

    I was recommended this serum by my beauty tech to help tackle the pigmentation on my face, I love that this had inhibitors that prevents the development of additional pigmentation.
  57. skin is amazing and pigments lightened

    Aksa

    I was a bit hesitant to buy an expensive serum especially after buying numerous others to no effect but I am really happy I bought this one. I have only been using it for 2 weeks and can see an instant reduction in the color of my pigments. My skin feels healthier and makeup is looking better. Will definitely purchase again. Worth the money. I made a number of personal recommendations.

    Within a single overnight use I noticed a difference in my complexion. This serum is packed with incredible active ingredients. With continuous use I have seen a rapid decrease in acne scarring, pore size and overall texture. My skin looks plumper and brighter with every use. Would absolutely recommend. If it's good enough for Victoria Beckham it's good enough for me.

    I’ve been using this product for almost a year now, and it’s really helped my sensitive, combination skin which can be prone to acne sometimes. I’m early 30s and I’ve noticed my skin’s tone has evened out, the small pigmented areas have become smaller and my breakouts are reducing. Fantastic product, which does take a little while to see a difference (at least 2-3 months), and though a tad on the ...
