Not much. The package does not say but retinol is the 11th ingredient in it. SO based on the fact the ingredients are listed in order of most to least, there is only a small fraction of retinol in this product. Personally I was not impressed with this product. After using an entire container I saw no difference. My recommendation would be save your money.

Sorry for can#t helping you. As my skin is very hard-wearing I never read the package information sheet or even the product despriction. But I found a list of ingredients here http://www.dermstore.com/product_Retinol+1.0+Maximum+Strength+Refining+Night+Cream_4505.htm. Perhaps this will help you futher on.

2% Hydroquinone. I might add that users should be alert for a sudden darkening of the skin. One day I noticed a new spot--1/2 inch x 1/4 inch--that had not been there before. I quit using the product right away, but two months later the spot is still there.

I do not know the percentage. It cant be so much if you can buy it over the counter. But I have very sensitive skin and am able to tolerate this well. I think it is a fantastic product I have been using it for many years.

The % percentage of retinol is not provided in the list of ingredients. I have purchased this product elsewhere and came here to find out if the % of retinol could be determined. After reading the info here for the product, glycolic acid is listed before the retinol and I am guessing there are different ways to combine ingredients for effectiveness - my experience has been ok but I am looking for something with more retinol, up to 1% and looks like I will go with Skinceuticals but not at Amazon as the reviews haven't been good

Depending on the amount used. Need only a small amount on scalp at night time

aloha Robert, I googled the term "retinol concentration" and found that it means the highest concentration. Neutrogena's product has 2%, hence why some people report feeling a tingly feeling when they apply it. You can find more discussion about it here: http://www.vogue.com/vogue-daily/article/the-return-to-retinol/#1 Hope this helps. I use this product and find it very useful at minimizing lines and wrinkles around the eyes and forehead. People have remarked that I don't look my age. The product also has an SPF of 30, which is fabulous as I live in the tropics. Sun damages ages the skin making you look older, I'd rather get my glow from a bottle of bronzer. aloha...k aloha Robert, I googled the term "retinol concentration" and found that it means the highest concentration.

I am not a medical professional but I do use them together. However since it can be irritating I cut my tretinol back to 3X a week. I would suggest you ask your doctor. And I was told the same as the person below said to use the C in the am and the A in the pm.

It's really weak so you could for sure use it with retinol. I used it in day and Tretinoin the strongest strength at night and I was fine. It doesn't really resurface as much as it feels like it hydrates like its just hyaluronic acid or something.

I take a small spoonful at night. I've read 1/4 tsp a day, for the higher strengths. Also may be applied directly to woulnds or skin conditions, or mixed with a little yogurt etc for a facial. Enjoy!

It doesn't say on the bottle. This isn't a multivitamin though and it's the last ingredient so it's going to be less than 1%.

I don't know the percentage of retinol, but I can tell you that this is a gentle cream that leaves your skin very soft and smooth to the touch. It does not cause my skin to peel or feel tight like it would if it were high in retinol. I am over 65 and my skin is much thinner than it was in my younger years and I am more sensitive to the retinol. I also have used this same cream in the version that is not for sensitive skin and this one has a better result. If you are looking for a cream that leaves you skin feeling soft and silky, this is a great product.

The bottle doesn't say. Sorry I wasn't much help. I think I read somewhere 20%

It IS 35%. It is packaged carefully and has to be stored in the refrigerator. There is a small hole in the lid that prevents pressure explosions. Please be careful to dilute this appropriately (down to 3.5%) before you touch it. DO NOT let it touch your skin before it is diluted! If it does accidentally drip on your skin, rinse the area thoroughly under cool running water for a few minutes. What I got from this company is indeed the real 35% concentration, and you must be careful to handle it as such.

I really like the product, but I am not certain of the percentage of retinol
