I was really eager to try this 252 Bohr pack after reading about this product before arrival, & understanding how it works. I was hesitant after hearing of some bad experiences with it. I was not 100% impressed, but it wasnt as bad as some of the reviews for it, in my own experience. It was above average. The packaging was very cute & neatly put together. I recieved the box with 1 face mask & a tube of the Co2 Therapy Gel. 😳🤔It did burn at first after putting the face mask on but I was prepared for that. I would NOT recommend this for sensitive skin though. You may put some of the gel on your wrist & test it with your skin but the burning sensation started when I applied the mask to my face/gel. It subsided after 3-4 minutes or so. I did get worried it wasnt going to ease off & only get worse for a bit. It did burn pretty bad in the beginning. Wasnt bad after that point. After removing the mask, my face did feel smoother, slightly hydrated, & moderately tighter around my cheeks & under my eyes. The only thing I did not like was how much it burned at first but its the process of how it works. Everyone’s skin reacts differently so, there may be different experiences with products like this. I dont like to leave any negative feedback or warning others with caution ⚠️ but I have to be honest so others can decide whether or not to buy it & maybe the company can resolve issues by feedback too. The burning or redness may be worse for some people so, I do recommend you use this with caution, read directions closely & if you are very uncomfortable, take it off immediatley & wash off. Follow up with soothing lotion or hydration mask. If your face gets to red, dont risk it with any further use & stop using it. This was a little above average experience & my opinion of this product is 4 stars overall. I recieved this from #08L free to try & my opinions are all my own. #252cosmetic #evenouteverything #252bohrpack #kbeauty #sheetmask #08L #beauty #trending #honestreview
