Unsure

So I’ve only used it once so far as it’s my first time using any retinal. I did breakout but I’m assuming it’s normal? I’m building my skin up to tolerate eventually. So can’t really say anything till a few months.

Noticeable difference

I have been using for three weeks and my skin does look fresher and less tired. At first it did bring out a few spots, which I do not normally get, but was told to stick with the product and I am glad I did.

Enjoying it so far

Its only been a few weeks of use, but I can tell that my skin looks more firm when using this retinoid. If you’re looking for a retinoid then you should definitely consider these products by Medik 8. Will continue using and then move to number 2.

My skin is glowing!

The first two weeks of using this product gave me spots but I had heard you have to persist with retinol and I'm so glad I stuck at using it as now my skin is so clear and GLOWING!

Simply great

I bought this to give my skin a break from prescription strength retinol, just wanted something a bit gentler for winter. I was expecting good things because I know how great Medik8 is and I'm glad to say that all my expectations were met. No breakouts, no peeling, just soft and even-toned skin. You can't really go wrong with this.

Mixed feelings

I’ve been using this product 3 times a week for about 1 - 2 months alongside with Vit C (which by the way smells amazing!) For the first few weeks my skin looks a lot more glowy and plumper but unfortunately I now have an acne breakout on my chin and jaw. It’s pretty bad. Worst breakout I’ve had since a teenager lol  I’ve researched it and it seems this can be quite common with retinol - almost like a purge! So I’m going to carry on and see if I come out the other side  … fingers crossed!

Not sure yet

I'm on my first tube of Crystal Retinal 1, and I have mixed feelings about it so far. Look. I'm 70 years old, and my wrinkles run DEEP, especially those on my upper lip .. so although I need nothing short of a miracle, I know that it's probably not going to happen. .. and so far it hasn't! Somehow, the lip lines don't seem to matter so much anymore because this cream has worked wonders on the OVERALL appearance of my skin. Fine lines are definitely reduced, my face is tauter.. and my skin is actually glowing!! So I'm going to buy a second tube, and I'll keep you posted about any improvement on the lip lines. Fingers crossed!

Gentle but effective

I started on Kedik8 CR1 as my skin can get quite sensitive. I have been able to use this every other night with no issues at all. Only on week 3 and family are already commenting on the improvement in my skin! Lovely to use and pleasant smell.
