I tested the product on my hand first and had no reactions. The hand became super soft and shiny. I carefully checked what not to use with the cream so I wouldn't have any chemical reactions, I do this every time I test new products. I applied the cream to my face in the evening and in the morning it looked super good.
So I did the same thing last night and today I woke up with severe rashes and swelling under my eyes. It burns, stings, itches, and hurts a lot. I eventually had to leave work because I couldn't focus due to the discomfort and pain in my face.
It seems that most people get good results and like the product, so don't be scared to try it, but a warning for those with sensitive skin to be careful.
Also, those who are prone to eczema, dermatitis, and rosacea should be extra cautious.
I think it might be due to the niacinamide that I reacted to like this.
Sad, because I use products from the same brand that work super well.
