I’ve been using the retinol for a week every other day and I’ve seen some improvement. Roc retinol has not irritated my skin. One pump of the serum goes a long way.

Been using the product for 2 weeks and can already see improved texture in my skin. This translates into a smoother foundation application and not needing to use as much primer on my skin. Great price point at Sam's!

Usually great product but unfortunately this was a bad batch. I have used this product for years but this batch blistered my neck and broke me out in welts

I have been using this product for a month or more and I do see an improvement in my skin. I didn't have much wrinkling but it does look better. I plan on continuing to using this product.

Very impressed after two weeks, although I may revisit my review after a month. I have had prescription Retin-A, which is effective but expensive. My research indicates that the "level" of retinol in this ROC product is fairly strong. I have already seen an improvement in pore size and a reduction of fine lines. The serum has a smooth consistency. The smell is not great, but it dissipates after a few minutes. One tip for this product (and most powerful retinols) is that it's best used a night.

I love this stuff.

Great product

My dermatologist recommended this to me three years ago and I did not take advantage of it at first, but once I tried it and saw the results and people started commenting on how young I looked: I was hooked. Then, when my dermatologist remarked on what a difference it had made in my appearance, I was really hooked: this stuff WORKS. I had an ER visit and whent he doctor came in he remarked that he must have the wrong room because I looked 30 years younger that what he had expected to see.

Burns every time I apply

Love this!
