The absorption is great. The photo below was taken in the living room lighting, so it looks a bit cleaner, but it's the same environment as the one above (before) and below (after). The dark circles also seem to have diminished a bit. Initially, my skin was quite dry and the complexion was on the darker side with many fine lines, but it seems to have improved. The ampoule contains growth factors, so it has a skin regeneration effect. They say one ampoule lasts 2-3 weeks, so I'll use one more ampoule in 3 weeks and post a review again.

Normally, the Activegen Ampoule 3 + Activegen Concentration 1 set should be used together to maintain the moisturized feel. If you just use the ampoule, it feels a bit tight. I was told that it has the effect of tightening and firming the sagging skin. Out of the 3, 2 need to be refrigerated, so while using the 1 that's not refrigerated... Like most functional cosmetics, it's a bit pricey, but if the effects are there, it's better than going to a dermatologist.
