Medik8 Crystal Retinal 20 Serum
I have been using Medik8 Crystal Retinal for years and would not be without it. Excellent product.

Very poor pump action
The pump doesn't work very well at all. I only want, and need, to use a minimal amount so I try to give a gentle pump to squeeze out a very little but that doesn't work. I have to pump 3 or 4 times for any to come out, but unfortunately by then, it pumps far too much out.

I think this actually works.
I know skincare takes a while, but I've used a few tubes of this (when it's on sale 😊) and my skin is looking more consistent in tone and smoother. I use it after cleansing with nothing else about 5 times a week. So many products seem to clog my skin up and make it breakout, but this is great.
