Magic in a bottle
This is a beautiful formula!! I’ve always wanted to try copper peptides, but they have always had a reaction on my skin. I get pustule rosacea on my cheeks and usually flare with every other copper peptide brand. I’ve spent hundreds trying. I believe in the science of copper and really want the benefits of it, if I could find the correct formula for me. Well, this is it!! It has NO copper smell, but is a beautiful dark blue. So I know that the copper is wonderfully encapsulated in a liposome to get where it needs to go without irritation. I’ve almost used up one bottle and have had no negative reaction. It’s actually improved my skin barrier and everything looks more even and calm. It soaks right in. I use this before my night cream, but after my growth factor. I do not use it on the nights I use a retinoid, just incase they are counter indicated (the science doesn’t really say one way or another yet). I live in the states, so now I purchase a few bottles at a time because of shipping and tariffs being so expensive, but it’s so worth it! Ok, I do only have one tiny complaint though. It’s about the packaging. I have a really hard time getting even pumps and all the product out of the bottle. I would really, really, love a package upgrade to something a little more air tight. Maybe a raising airless pump, or even a squeeze tube? Other than that, I am very pleased and will keep this in my routine as long as I can get ahold of it. Good job Leitin! Keep it up.
Been using every night with my retinoid since September ( it's now end of October) and I think it's working. The combination has boosted the clarity, texture and softness of my skin. It seems to be a winner, just about to order my second bottle.
I’ve almost finished my first bottle and am buying a second. I usually have decent skin but I think this has made it even better
My sister won these amazing products for me! I am so happy that she introduced me to them as my skin feels so beautiful. I am not sure if Leitin does a sunscreen but this would be a lovely addition to my collection
My favourite Vitamin C serum Already on my 4th bottle, and I honestly can’t live without it.The glow the results it’s a forever favourite! 🧡
These 2 products together are a powerhouse. Have noticed my pigmentation is fading significantly , the longer I’m using it. It’s been about 5 / 6 weeks so far and it’s going well. My skin is very luminous. LOVE IT

This serum is so amazing. Can't wait to see more results as time goes by
Store owner replied: Hi Ashlee, Your skin looks amazing! Thanks so much for taking the time to review the LS5 Copper Peptide Serum. xx
First of all, this was my first order from LEITIN. One day I found LEITIN through TIK TOK influencers talking about this Brand. I have used The ordinary copper peptide& NIOD however it didn’t made me feeling use it for long time. I heard so many benefits of copper peptide but always struggled to find good brand which I can afford for long term. LEITIN copper peptide seems really promising. I liked everything when I use it, very hydrating and smooth feeling when I use it. Unfortunately I had to stop using it for couple of weeks because I completely damaged my skin using other activities but once my skin gets better I will start using it again❤️
Store owner replied: Thank you so much for giving Leitin a try and sharing your experience! We’re so happy to hear you’re loving the hydrating, smooth feel of our Copper Peptide Serum. We completely understand needing to pause your routine while your skin recovers, so take your time and be gentle with your skin. We’ll be here whenever you’re ready to reintroduce the serum! Reach out if we can help with anything. Thank you for your support and trust in Leitin. xx
I’ve noticed slight fading on my melasma on my right cheeks and nose. I love the feeling and smell when I use them. Hopefully in the next few weeks we’ll see some changes
Store owner replied: Hi Effie, Thank you for sharing your experience! We're so happy you're enjoying the LSP Serum and already noticing some fading. Consistency is key, and we hope you continue to see improvements over time. x
This is the highlight of my routine. It is an absolutely gorgeous product, smells divine and locks in so much hydration at the end of my routine. I’ll never be without it!
Store owner replied: Hi Kathleen, So glad the products you're using are keeping your skin feeling and looking Hydrated. x
I absolutely love this formulation. I have very minimal under eye creasing now because I'm super hydrated and virtually no crows feet (unless I laugh really hard) and this cream is helping me maintain that. I'm almost 53 (as at Aug 2026). I'm using lots of products from this brand and all of them have been amazing. Another thing I love is the amount you get!! It's huge!!
Store owner replied: Hi Michelle, We absolutely love hearing this! It’s wonderful to hear how much you’re enjoying the formulation and that your skin is feeling so hydrated! And we couldn’t agree more, getting plenty of product to enjoy is always a bonus! Thank you for trusting Leitin with your skincare routine and for your amazing support across the range. It means the world to us! ❤️ Leitin Team x
It’s only been a few weeks now and have noticed a significant amount of fading on a large pigment patch on my face. Like they say … skin care is a marathon not a sprint but this stuff is definitely doing it’s job
Store owner replied: Hi Melissa, Thank you so much for sharing your experience! 💕 We’re so happy to hear you’re noticing a difference in your skin already. You’re absolutely right, skincare is a marathon, not a sprint, and consistency is key! Thank you for being apart of the consumer trials. xx
Dear Leitin, I absolutely love your products thankyou. The LSP serum is again a winner Issues that i have is that there are so many products to apply, and it can be quite time consuming (due to some products needing absorbson time) and i lose tract of what products i have applied and which i haven't. I love being part of your research. I have noticed that there is now a 3% copper peptide on the market now just fyi. Kind regards Jo
Store owner replied: Hi Jo, Thank you so much for your lovely feedback and for being such a valued part of our research journey. We’re thrilled to hear that LSP Serum is another winner for you! We really appreciate your honest feedback about the time involved in applying multiple products and keeping track of your routine.

Loving this eye cream, 2 weeks in and it’s the best! So many others haven’t cut it and I end up with milia from them, here’s hoping this is the one.
Store owner replied: Hi Che, Thank you so much for sharing your experience! We’re so happy to hear you’re loving the eye cream after just two weeks! We know finding the right eye cream can be tricky, so we’re delighted this one has been a great addition to your routine so far. Thank you for giving Leitin a try. xx
As an almost 53 year old, I've virtually used every formulation of Copper Peptides on the market. To me, this is comparable with the best (Medik8 Advanced Peptides MP in the black bottle) BUT WITH A MAJOR DIFFERENCE. This serum lasts a lot longer, I also think it's slightly stronger (I'm on my second bottle, so I've tried it for over 3 months without altering anything else) and I've seen fantastic improvement. I've got very high standards for Copper Peptides as I think they are just as important as retinol/tret when you get to the over 40 range, and this has proved to be exceptional. As is everything else I've tried so far (Vitamin C, Holy Oil, Eye Cream) and can't wait to try more. Love that it's an Aussie formulator too💖
Store owner replied: Hi Michelle, Thank you so much for this incredible and thoughtful review! It means so much to hear such positive feedback from someone with your experience using copper peptides. We’re thrilled that you’ve seen such fantastic improvements over the past three months and are loving not only the serum but our other products too! Your support for an Australian-formulated brand makes it even more special. Thank you for trusting Leitin with your skincare journey, we can’t wait for you to discover more! 🇦🇺✨xx
This is by far the best facial oil I've ever used. I apply every night as a last step over moisturiser to lock everything in and I wake up with the most soft skin. I'm 52 and a skincare addict with extremely high expectations and adult money. I mainly use Korean formulations, except for this brand, which I've found to be incredible with great results. I use the oil, Copper Peptides, Vitamin C & Eye Cream so far and I'm waiting for the pigmentation serum. This oil smells fantastic and has banger ingredients. Will never be without.
Store owner replied: Hi Michelle, Michelle, thank you so much for this incredible review! 🥹💕 We absolutely love hearing this, especially from someone who knows their skincare and has such high expectations! We’re thrilled that Holy Oil has earned its place in your nightly routine and that you’re loving the results from our other products too.xx
This is my second purchase of Halo and it sure won’t be my last! Love this product ❤️

It means so much to know you’re loving the product, and we look forward to being part of your skincare routine for a long time to come! Leitin team x
Love this for my more mature skin in the evening Did take my skin a bit to get use to. Need to remind myself to allow time for each of my products to absorb before putting the next one on 🤣🤣. Great to lock in all the other skincare.
Store owner replied: Hi Tracy, Thank you so much for sharing your experience! We’re so glad you’re enjoying using it as part of your evening routine and finding it a great way to lock in all your other skincare. It can take a little time to find the perfect rhythm with layering products, and allowing each one to absorb before applying the next can make all the difference. We really appreciate your support! Leitin team x

Absolutely best eye cream I couldn’t ask for more. It’s improved my eye area so much it’s made it firmer and the wrinkles don’t look as defined. Absolutely love this product and will always use it. Can’t recommend it enough.

I use this on nights when my skin feels it needs more hydration. It’s a thicker consistency but still feels light and readily absorbs. Also pairs beautifully with the Holy Oil for an extra hydration hit.
