Okay, I'm checking in early to say that by stopping the HA5 and TNS, I am completely back to normal. My face definitely is less smooth and hydrated, but I'm grateful to have figured out the culprit of the allergy. Something changed in their formula. Very disappointed that I spent a lot of money on these products that promote a medical type of beauty product. I am going to report back in a few weeks again because I've had a strange autoimmune anaphylaxis condition ever since I started the HA5 2 years ago. I never thought it could have been that product, but my condition has drastically improved over the last week! I'm shocked and I will keep you posted!
