Cannot go without it!
I’ve never left a review on anything but I couldn’t NOT for this product. I had tried everything over the counter, tretinoin, those useless hormonal balance pills…was so close to giving up and starting Accutane as a last resort. After being bombarded (kindly) with Lissy TikTok ads and hearing the founders story etc., I caved and splurged and thank God I did.
This photo shows how my skin has changed from October 2025 (when I ordered the serum) to January 2026. I had both hormonal and cystic acne for years, and now I just have some leftover scarring, but it’s easy to cover up. My skin is finally smooth and my confidence is back. $50 is literally nothing for the value and results you get, and I’m still on my first bottle so it lasts pretty long.
Thank you thank you thank you!!!
Love these products!!! My face hasn’t felt this smooth and clean in years!
I switched off of my dermatologist skincare routine because I was tired of harsh topicals on my skin. Safe to say my skin FREAKED OUT. I tried primally pure for a bit in an attempt to see if a holistic approach would help. That didn’t help at all. I found Lissy skin on Instagram and decided to go for it. The mandelic serum did wonders for skin texture within the first month and as soon as I paired it with their face wash I started seeing insane results. I still use niacinamide as well. But their products are gentle and affective - not harsh like benzoyl peroxide or other harsh topicals! If you’re making the switch from harsh ingredients but still want clear skin - you’re in the right place!
I have been struggling with hormonal acne since beginning a ton of supplements to boost fertility about 3 years ago. I have tried everything, including going to a dermatologist for recommendations. Nothing seemed to help, even the skincare I bought straight from the derm. I came across a video of lissy skincare on instagram, and within a few seconds I was checking out...the definition of an impulse buy. It has been about 5 weeks, and I am so relieved to have found something that works! Right now I only have 1 active breakout, but it never really broke through and is already going away. I am very impressed with this serum!! Thank you!
The best thing you could do for your skin is buying this!
I love this stuff! I have always struggled with acne, and have sensitive skin so it’s a challenge to find something to help without being too harsh. I purged for about 2 weeks and then started noticing clear skin and fewer breakouts. My face is much more clear, and SO smooth. I will definitely be repurchasing. Thank YOU!
Works like nothing I have ever tried.
Never before has my skin EVER been this clear. I truly felt at a loss of what to do before I decided to finally try the mandellic serum. It has CHANGED MY LIFE!
This is so hydrating yet effective in helping me with my acne without over drying my skin! I do wish there was an option for 8% mandelic acid for people with severe acne or in my case when I have big flare ups randomly so I can switch between the 5% and 8%. Overall my skin is feeling so healthy I love it!
