For morning use. It's not that it's great, but it doesn't make my skin worse either, and I don't think it affects my makeup.
I feel firmness the day after applying it.

Who would have thought that Sofina iP would have released an all-in-one product! There were about three types (I think), but I chose this one because I was concerned about firmness. The feel is okay. Since it's anti-aging care, I thought it would be more moisturizing, but it's surprisingly refreshing! But it's probably better than the unpleasant stickiness. When I'm too lazy to do my skincare routine, I use this before going to bed. When I use it together with the carbonated foam serum, my skin is definitely softer the next morning.
