Great review! I laughed about the jaundice comment. I have yellow undertones and one day I was standing next to my daughter who is pale with rosy undertones and I was shocked at how yellow I looked and told her I looked like o had jaundice when next to her 🤣
my skin is normal leaning dry and it works well for me. Anything with actives so depends on the person, so if you have had success with niacinamide in the past it may be worth a shot.
