The liquid retinol had a watery, smooth texture that made it easy to use. It had a sweet, sugary scent (?). It didn't sting or feel sticky. I bought 10ml and used it every other day, and it was gone in a month. It was hard to see any changes in my skin, but I think if I'd used it every day, I would have noticed a difference.
It's a light liquid that you apply all over your face and let it absorb, but I've only been using it for a few days so I don't know if it's effective.
It's as smooth as water and has no scent, so it's easy to use and blends well with the skin.
It's refreshing and comfortable to use. I'm not sure about the effectiveness yet. For now, I'll try using it until it's gone. I'll also try using it in combination with elastin and vitamin E derivatives to see if it's effective. I'd be happy if it helps with sagging and fine lines... (^^;)
I started using it for the first time in several years, and I definitely feel there's a difference between having it and not having it. I only apply it around my eyes, and it doesn't improve wrinkles, but it does give me a firmer feeling.
