400,000 I.U's of Vitamin A which is a source of Retinol. No other information given. Be sure not to overuse---as Vit. A can cause irritation.

According to Wikipedia, 1 IU of retinol is 0.3ug, so to convert to % w/w: ((0.3ug x 400,000)/63g)*100 = 0.2% retinol. This would be functionally equivalent to about 0.002% retinoic acid.

Any Retinol product is going to make you peel one way or another. Some have a regular problem with peeling so I would use a 2% product, I have had very little peeling with any Retinol product.

The ingredients does not state the percentages. It only list each one. So I am not sure how much salicylic acid is in the bottle. It is a great product that I use on a daily basis.

The current formulation is what we have found to be the most successful balance of retinol and other ingredients to make sure skin isnt too dry or too oily, that is at 7% retinol.

The bottle does not state a percentage. That being said, I have always found NOW to be a reputable and effective brand. I use the oregano and have had good results.

Not sure what you mean by "percentage". If you mean % of US RDA, then Vitamin D3 600 IU = 150%; Calcium 1g (1,000 mg) = 100%; Magnesium 500 mg = 125%; Zinc 10 mg = 67%. Hope that helps.

I am unsure of the retinol percentage. I am an avid user of this product, unfortunately I can't afford it right now, so I am currently taking a break. As soon as I can, I will be restocking it. I have acne (cystic/hormonal)prone skin, I have seen a pleasant difference in my skin tone, acne, and wrinkles very shortly after starting this product. I miss it- my face misses it!

That 10 parts of the ingredients in the entire container should be Retinol.

Sure, no problem. You can take a look at the Supplement Facts image (I think it is the second image in the gallery), the chart shows there the vitamins percents per each serving. You can always find out more by emailing the company directly at service@solandsam.com, I had a question about purchasing it locally and they were very helpful.

Actually it says it has 1000,000 IU's of vitamin a per ounce, hope this helps, does not say anything about the retinol.

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

They must have added those percentages since this question was posted cuz it is stated in the title: Vitamin C Serum 22% C + 11% Hyaluronic Acid + 1% Vitamin E + 1% Ferulic, also Contains Organic Aloe & Jojoba Oil + Advanced Amino Complex

It doesn't specified the amount of retinol as I had hope. But I just looked it up and retinol is a simplify form of Vitamin A of which this products states clearly in the front of having 1000,000 IU per ounce. There is 2oz. in the jar so I guess it has double the amount. I hope this helps. I really do like how soft and subtle this product makes my facial skin and even the rest of my body. I've only been using it almost a month and I don't have wrinkles for being a women near 50 to be able to tell if it helps reduce wrinkles. But I'm hoping it keeps them away longer now that I'm getting older. Good Luck! It doesn't specified the amount of retinol as I had hope.

It doesn't list the percentage. It is the 4th ingredient listed on the label. I can tell you this company is wonderful, and you really can't go wrong ordering from them. Their customer service is the best I've ever seen. Try it, if you're not thrilled with the product, they will give you a refund, no questions asked.

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.
