I am not sure why cosRX reduced the percentage of BHA and didn’t make the pH level really low. One of the major complaints with the BHA Blackhead Power Cream was that people felt its pH level was too high for the percentage and now they made it even more weak. That said, I actually do like this overnight mask pack ~ it is gentle enough for me to use after I micro needle my skin ~ it won’t irritate it and I can use it nightly if I want to. I actually layer some other watery BHA acid products on my skin before applying this ~ and I can say that this product does work in the same manner as the BHA Blackhead Power Cream ~ my skin looks clearer and feels smoother and softer. However, if you have blackheads, you will need to use a stronger BHA product to tackle those, but for those who do not suffer all the time with blackheads, this is a good product. I just wish cosRX had made the pH level a 3 and had a stronger percentage of BHA in here. Maybe with the next reformulation, they will. The old formula had its issues as well, so I am not in despair over these changes ~ it works just as well, I believe and it doesn’t cause me to break out. My skin is soft, smooth, blemishes are reduced in size and my skin looks clearer. All in all, if you liked the BHA Blackhead Power Cream, you will like this product as well!
