We are testing the Ren Bio Retinoid Anti-Ageing Concentrate this week.
More info about the product benefits to follow.
Ladies, the initial response I got is that the sample only lasted you three days rather than a week.
This is my error, please don’t include it in your reviews.
Again, these are small samples so if you can focus on the short-term feel of the formulation rather than the final effect which after few days cannot be that much. Thank you.
*****

Increases collagen production by 24 % (in vitro tests).

I have been using the Ren Bio Retinoid Anti-Ageing Concentrate on my combination skin. The sample has lasted for 3 nights. I have noticed my skin has felt softer after use but I haven’t noticed any other changes. Perhaps the product would have to be used for a longer period of time to see any real improvement.

I have used the product for about 4 days, the smell is lovely, really natural and fresh, I find the texture a little sticky but it does absorb well. My skin feels soft but I can’t say I have noticed anything else. I’m not sure I would buy the product although I think I would need to use it for longer to assess the benefits listed above.

My first impression of this product was that the scent was unusual, but not unpleasant.. It had a nice smooth texture and a little went a long way. I noticed even after the first use that in the morning my skin looked really plumped up, soft and smooth. I would like to try it over a longer period given the positive effect noted in such a short time.

I enjoyed using this product although didnt see any change in my skin. The smell reminded me of the Trilogy Rosehip oil which I love, although the oil is heavier than the REN product and I preferred the texture of the REN. I was a bit hap-hazard with my application of the product, perhaps I would have seen more change had I applied more product to a specific area rather than finding I had pumped too much out and feeling I needed to use it (to used it up on my neck).

Carolina’s feedback: Initially I thought the product was going to make my skin oily given the consistency, but my skin soaked up it up quickly and felt instantly hydrated. I have skin that tends to be dry but I felt I could have used it alone although I followed the instructions and applied it under my nighttime moisturizer. It has a really pleasant, light smell which I liked. In the morning my skin has felt much smoother, softer and has remained very hydrated, much more so than when I use my nighttime moisturizer on its own. This is my favourite serum I’ve used to date and would purchase it based on how my skin feels after three days.
