Is medik 8 crystal 3 worth it

[Lottiebugz22]

And can beginners use this?

I use their intelligent retinol myself and have been really impressed, but I believe the crystal is fine for beginners. I'd introduce it really slowly though (especially if you've never used retinol before). Not sure if you've seen this but medik8 have a really good guide to their different vitamin A products which can help you decide which to go for: www.medik8.com/vitamin-a-guide.html
