THE LISSY DIFFERENCE
-
Acne-safe, fungal acne-safe, and pregnancy-safe
Many acne treatments tend to be too harsh, trigger fungal acne, or are not recommended during pregnancy. Our mandelic formula was designed to effectively target breakouts while remaining gentle and safe for all three.
-
Gentle exfoliation without irritation
Mandelic acid naturally works at a slower pace than traditional acids, helping clear congestion and smooth texture while being well-tolerated by sensitive and reactive skin.
-
Treats acne and discoloration at the same time
Helps reduce active breakouts while visibly fading post-acne marks and improving overall tone and texture over time.

Gives my skin a smooth texture!!
I’ve struggled with my skin for as long as I can remember. Lissy Skincare has truly been a game changer for me. I’ve dealt with it all — cystic acne, fungal acne, perioral dermatitis — and I have super sensitive skin, so I’m really careful about what I use. I do my research, and Lissy Skincare is gentle but effective. I’ve recommended it to so many people because it’s made such a difference for me.
The photos I’m sharing are mild compared to when my skin was at its worst!
The best serum ever. Changed my skin so much!!
I have noticed an actual difference when using this product vs prescription tretinoin or adapalene. If you get tiny forehead acne or even cystic acne this works better (at least for me). And I have really sensitive skin so this is saying a lot!
I’ve been using the Mandelic serum for about a month now after struggling with hormonal acne for the last 6 months. I used to use benzoyl peroxide which really stripped my skin and I could tell that the mandelic serum made a difference immediately in bringing the moisture back into my skin. It has made a noticeable difference in my scar healing and redness and it also helped with preventing breakouts on my back. I feel good about the fact that this company is transparent with their ingredients and makes sure it’s safe for sensitive skin. I am planning to buy more of their products and ditch the ones I was using before that I don’t feel like I can fully trust. I’m sure it will take awhile for my skin to bounce back from the hormonal acne but this is the only thing that I have used that I could actually tell it made a difference!
I love this product! I was able to stop tretinoin by using this! It clears up my cystic acne so well!
I almost went on Acutaine for the third time. I tried the Pink bottle and O MY it is my holy grail. I am obsessed.
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!
