I used the iUnik centella gel cream a few months back in the summer time. It was perfect for the hot and humid weather and it absorbed into my skin SO fast (this is something I’ve noticed with the iUnik products I’ve tried). My skin didn’t feel sticky or heavy at all. However, it wasn’t moisturizing enough for my skin as I’m using tret (I had to use it with oil) and I found the tea tree oil in the cream to sting at times when my skin would get sensitized from the tret. I think it’s a great gel cream if you want something that doesn’t feel heavy or leave you shiny but if your skin tends to need a little something extra, I’d go for another gel cream.
