Lissy skin care serum

I've only been using this product for a week and can already tell a difference! It has made my skin texture so much smoother, and I'm noticing I haven't developed any new cystic spots since using.

I Would give it 10 stars if I could! This serum has changed my skin significantly ❤️ I have sensitive acne prone skin, and this gentle yet effective serum has cleared my acne and helps maintain breakouts from my period! I will scream from the rooftops about this serum! Three of my friends favorite serum as well ❤️ team lissyskincare ( and her customer service is unmatched 🌸)

Buy this serum

Fellow esthetician here! I ordered this serum for myself and saw changes in my skin within a WEEK. I didn’t think I had much else to work on but I looked so glowy and my hormonal breakouts were fewer and didn’t last as long. I’ve recommended this to a few clients that had stubborn acne as well and they had the exact same results! It truly works for everyone.

My skin felt so glowy and evened everything out

Love it!

I’ve had crazy hormonal acne ever since I got my IUD and haven’t been able to get something that consistently works. I’m an esthetician and so I’ve tried tons of things. This serum is an absolute game changer!! Love love love it!


Looking for healthy skin? This serum is it!!! I’m on my second bottle and it’s been such a game changer, especially on my tiny texture bumps! As an esthetician whose struggled with acne for so long I’m so grateful to have found this product. I recommend it to so many of my clients as well. Thank you Lissy!❤️

Love this stuff!

I’ve been using it for a couple weeks now and my skin has been glowing. 🤩 I didn’t have much acne to begin with, but my breakouts are very small and go away super fast - plus they don’t scar!

This is my skin’s godsend!!

I am obsessed with this product. I recommend it to everyone. It’s amazing!!

A must have!

My skin has been loving this serum so far. I haven’t had any dryness or breakouts which is unusual for me. It lightens my hyperpigmentation faster than any other product I’ve tried. A true holy grail serum that will remain a staple in my skincare routine.

best serum ever.

i have been using this serum for the past 2 months now after my esthetician recommended it and i am OBSESSED. I use it every other night since I have really sensitive skin and it’s worked wonders. It makes my skin feel really soft and glowy. I’ve never been happier with my skin than I am now. Thank you for making this amazing product, I will keep purchasing forever!

Quick Results!

I've only been using the Mandelic Serum for about two weeks, and almost immediately saw brighter, healthier skin! I am pretty low maintenance on my skin care routine, but this has become an everyday staple!


There is not another mandelic acid on the market that even comes close to this product- I’d go as far as saying there’s not even another serum that compares. Lissy has blessed the skin world with this product.
Coming from a fellow esthetician you will not find another product that even comes close to transforming your skin the way this does- idk what lissy be doin but she needs to be doin more of it- the skincare world called and she answered.
If you’re still skeptical please check out my before and afters!

Cute & effective!

The packaging is so cute AND it works. 10/10!

I’m obsessed!

This is the only thing that has helped my textured skin!! I had pesky bumps under my chin and now they are completely gone! I am obsessed and I’m so happy it has cleared up!!! 🙏🏼🙌🏼


This is one of my fav products!! It truly has taken my decent skin to AMAZING so quick. I didn’t really struggle with acne before, just wanted something to give my face that extra glowy look and feel and this did the trick!!

Routine Staple!

I was in my first trimester of pregnancy and dealing with the worst acne I’ve ever had. Then Lissy suggested I start using her serum and it changed my face. I’m completely serious when I say that I haven’t had a zit since.

My Holy Grail Serum!

I absolutely love this serum. I wanted to wait a few months before posting my review, I started this product back in september and my skin has improved sooo much! I was struggling bad with cystic acne because of a different product that destroyed my skin. This serum completely changed my skin in only the first few days of use. The inflammation went down so much. My pimples clear up overnight when I use this. It’s incredible. My boyfriend has been struggling with breakouts around his forehead and temples, I’ve been using this on him too and he loves it! It helps so much. These pictures speak for themselves! Thank you Lissy for creating this amazing product!

My skin hasn’t been this clear in a very long time! The texture of my skin is so smooth and this serum doesn’t dry my skin out at all. Couldn’t recommend this product enough! 😊

My skin has never been more clear. This product is absolutely amazing! I’ve noticed a huge difference in the short time I’ve used it. What an amazing company and product!

Never received Serum..

Purchased the serum and still haven’t gotten a shipping tracking number, no updates and haven’t received the item.

Oh no!! I just tracked it and it looks like it’s lost in shipping. We will get a new one sent out right away! So sorry for the inconvenience <3
