I have had so much of my acne clear up! Which I didn’t even think was possible anymore after I’ve tried literally everything, including 6 months of accutane!

worth it!!

i have noticed my acne starting to subside and decrease! i have also noticed a glowier texture and more soft skin on my face and not as much texture as before!!!

holy grail

oh my gosh i have been using g it for a month now & wowww its prevented my hormonal breakouts that come around y period and i haven’t even gotten a single pimple since using it. obsessed. it does burn a little but moisturizing right after helps. great lifesaver product

Works so good!

An essential

Long time sufferer of fungal acne and perioral dermatitis and this serum has been sooooo helpful. Gentle enough to not flare up my PD but effective in preventing FA flares

I’ve been using every other day since Tuesday. The first day after use my skin was softer! I have small bumps and rosacea on cheeks and it was already lighter! I still am having a few breakouts but I have very sensitive skin to new products and just stopped my acne meds so I don’t blame the serum for it! I’m super hopeful for the next few weeks/months! So far I’m loving it! I’ve had cystic, small red bumps, rosacea, and just breakouts on forehead for 3-4 years now and I’ve tried multiple acne products and nothing has shown me results like this has so fast! I definitely recommend! As you can see the close up; my skin is red and have breakouts. The 2nd pic my skin is clearly less red and brighter, breakouts clearing up!

Life changing!

Less discoloration, acne reduction almost immediately.

i haven’t been using this product long, but so far i love it! it’s clearing my acne and more even/smooth skin

I’ve been using this for a little bit less than a week, but I can tell a difference! This is literally the only thing that has been helping my very hormonal acne, I can’t wait to see what my skin looks like in a month!


So fluffy and cute

best purchase <3

Stay faithful to the process

It took me a little over 3 months to see serious results. But they came ! The bumps on my forehead are almost all gone!!if you’re like me and it takes a second to see results don’t give up! The results are worth the price. I’m starting to feel confident in my skin again.

Holy shit this works!!!

I’ve noticed such a big difference after only using it for about 4 days! My skin feels smoother, glowy & has definitely helped with my acne and pigmentation on my problem areas of my skin.
I love this stuff! The only downfall is it took me too long to find it! :)

Wonderfully Surprising

I recently started getting terrible hormonal acne after going off BC. Although I always have struggled with random cystic acne this is the worse my skin has ever been. I saw on TikTok this Lissy Mandelic serum and thought, there’s no way this will help my skin, I’ve tried everything for years! This serum completely surprised me because within a week I started noticing a change in my skin. Now within 14 days it’s only getting better each day. So far this is serum amazing and has changed the game! Will continue to order and highly recommend!

Seriously amazing stuff!

I didn’t realize how much my skin needed brightening until I started using this serum! My skin did purge, but the results were worth it.

I am in awe. I have had painful persistent acne for months. And when I say persistent I mean it. Break outs in the same spot over and over again with daily breakouts. Nothing was helping clear my skin even prescription topicals or medications. I was feeling so defeated but kept seeing Lissy on my FYP. I have use this serum twice. TWICE! And I am already seeing improvement and have no painful spots on my face. My only regret about this product was honestly not buying it sooner.

This is HG!

This has quickly reached holy grail status! I don't normally leave reviews to be honest but this product really is worth it and i don't ever want to be without it. I saw immediate results in my skin looking brighter, redness diminished and no negative reactions at all. It feels great going on and absorbs with no residue or sticky feeling. I love it!

immediate results !

Under the skin cystic pimples that usually never go away fading, dryness but nothing crazy in comparison to medications I’ve always used from dermatologist
