I got this in the limited edition beauty box and it is literally the best product I have ever used on my skin. Ever. Ever. I can't recommend this enough or believe the results. I've been using this every night for 3 weeks, I had deep erm..."water bottle" lines on my top lip, after years of drinking from sports bottles. Well, no longer. They are minimal. After just 3 weeks! The product feels light and dewy on your skin. I've been rubbing any excess into my hands, and it has made an incredible difference to how they look as well. I've been disappointed by so many products over the years, but for us mature ladies (and gents) this is a true game changer. It's amazing.

It's not irritating at all. Good retinol serum for beginners

it is my second bottle, I enjoyed using it, you need a lot of ancient to see the result, that will come in several month. 

This was the first product that I used with retinol and as I heard retinol is a strong ingredient and it must be used with care on your skin, so I was a bit concerned about the concentration from this product. After using it the first night I haven't had any reactions and decided to use it the second day too but with no effect. I didn't had any discomfort from it so I believe that this is not such a powerful product. I have used it for a few weeks now but I can't say I've seen any improvements on my skin. Definitely I wont buy it again!

I have tested out quite a few different skincare brands and a few months ago I thought I'd give PTR a try. I bought a set of PTR products, this included - unimpressed with all and won't be buying from this brand again. This retinol product feels oily and very runny, I've seen no long term/short term difference, it doesn't even feel like I'm putting anything on my face.
