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.
Sorry to hear that you experienced something uncomfortable. Worth noting that Korean products are actually made for Asian skin, and can also have an effect on Western skin.
