Well worth the investment into your skin.
I have 50+ year old skin that has enjoyed regular sun exposure, I have some age spots, enlarged pores around my nose, chin and forehead and lines around my eyes and lips, plus sagging skin around my jowl line.
The bottles require the product to be pressed through the lid into the bottle and then shaken to distribute through the liquid which was easy to do.
The solution was easily absorbed into the skin and I immediately noticed brighter skin.
Over the period I used this system I noticed that my skin began to look more refreshed and supple, this was especially noticeable on my skin around my cheeks, my chin and jowl, where the sagging has noticeably improved, in particular the vertical cheek lines I had started noticing have disappeared.
My pores seem to have also diminished with a noticeable improvement in how my make up sits on my skin. I don't need to powder as much to disguise my pores hence my make up looks dewy rather than cakey and looks fresher for longer.
Overall I am very happy with this system and will continue to use it every few months to give my skin a boost.
