This is my favorite rationol product from Rodial. You need additional hydration if you use this serum. It requires three or four weeks for skin to adapt this serum. I was using the serum together with collagen serum from the same brand and I see very good results on my skin.

Only ever had the Rodial banana lowlighter but was desperate to try the Retinol drops. Only been using a couple of weeks but really impressed. I had sensitive skin but no issues at all. Use at night and loving it. So pleased I decided to try this product !

It might be 10% or might not be but it is more effective overnight, sratch that, imiediately effective.
I have life threatening skin autoimmune condition (not fun) and this thing keeps it in place. Nothing else works. None of the drugs anyway.
The Or....'s 5% retinoid is weaker than this. I just have to wait for sales, this is very expensive.)))
The rest of skin's surface is restructred by it too. Beauty value is there no doubt but it is actually a meficine for me. Thank Gd there is something...you have to get used to stregnth though. I had a little reaction to it first, but not now.
I do not know any other product on the market with higger efficacy. (without remortgaging your house say)

I had CO2 fractal laser treatments in January and the doctor told me that I should use some form of high quality retinol product nightly from now on.  This booster is wonderful!!  4 drops applied on clean, dry face and you wake up with glowing smooth skin.  I did not experience any adverse effects such as redness and irritation.  This fluid really glides across your face and since a little goes a very long way, it is also economical!
