I’ve been using bacno LHA serum for a while now. I bought it during March so it’s been good 3.5 months now. The bottle still had half of the serum yesterday ( but my sister decided to break it today so I wasn’t able to use that considering it was not exactly cheap either makes me kinda sad).  
But using it for that long I can tell it’s a very good formulation.  
Helped me with my comedones alottt. My skin has become so sensitive that it can no longer take a Salicylic acid as a leave on, Considering all of that I bought this LHA serum I use to use akmas if I felt like I need deep cleansing.  
So my routine was more like

Day 1 (LHA serum)  
Day 2 ( Azealic acid in the evening and skin A at night)  
Day 3 akmas cleanser at night ( for deep cleansing akmas is holy grail)   
After cleansing lots of moisturiser   
And repeat   
I adjusted this routine according to my skin needs too sometimes   
With this routine I used possible gentle cleanser and flexione moisturiser 

My comedones  the ones I didn’t even know existed purged. The marks faded with this serum simultaneously. It doesn’t make your skin feel very sensitive to the sun either. It’s not like salicylic acid by using salicylic acid serums religiously I noticed that at some point it damaged my barrier which lead to more CCs. So this one gives you glow and it’s 100% non comedogenic ( some serums clog pores too). LHA ph is more on a neutral side but SA is more acidic maybe that’s why it suited me better.  
So yeah that all I had to say.

As I haven’t seen much reviews on this serum so thought I should write one.
