I've used many other retinol products, but this is by far my favorite. Helps a lot with stubborn cystic acne and dark spots, my skin cycles much faster.

I have sensitive skin and this product works great. Any redness I have goes away almost instantly after I use it. I use retinol mostly for aging prevention. I don't get bad acne but if I have any breakouts it makes them heal so much faster and look visibly smaller and less red almost instantly. Hasn't dried me out. The only down side is I noticed it tends to pill up or peel when putting on moisturizers, some more than others. Its not a huge deal, I just a moisturizer that doesn't make that happen, or I put the moisturizer on a bit quicker than I would normally after the serum so it soaks in cohesively. Also, I've noticed if you don't rub the moisturizer in too much it helps. Other than that though, amazing retinol, very happy with it.

I have only been using this for a week but I already love the results. Right now I am applying this serum every other night to avoid irritation. I wake up with soft and glowing skin the mornings after I use this product. Over time I'm hopeful to see more dramatic results in the reduction of some post acne hyperpigmentation.

This was recommended by my esthetician to use twice a week at night. I have been following her instruction and my skin looks and feels great.

I have been unable to use other retinol products in the past because they were too harsh for my skin. This works great for me- no irrigation at all.

My derm recommended this over the Tazorac I had been using (for anti aging & acne). I hated Retin A (terrible breakouts), so I was nervous, but this stuff is great. No breakouts & smooth, healthy,firm skin. I'm back to buy another bottle!
