I'm 41 and my skin is oily and sensitive. I used to have a bad skincare routine, but now I'm trying to take better care of my skin. I researched and came up with a new routine. I use micellar water and a facial cleanser to clean my face. Then I use a toner and serum with glycolic acid and salicylic acid. I also use eye cream. I've been using these products for two weeks and so far, they're working well. I didn't take a before picture, but I took one on day 7 and I'll take more pictures every week until I finish the bottles. Here's what I've noticed: my skin looks brighter, I had fewer and less severe breakouts this month, and my wrinkles have improved a little. I don't use the HA (hyaluronic acid) much because I don't need that much moisture and the Vitamin C already has it. If I do use it, I use it at night because it makes my face too shiny during the day.
