  • Amy limit to how much Retinol can be used?

    Posted by DavidW on October 25, 2017 at 7:11 pm

    Does anyone know if in the USA there is a limit set forth by the FDA as to how much retinol (not palmitate or any other form) can be used in a topical cosmetic (not OTC) skin product?  Can a product contain 3%?

    I don’t know of any limit except for use during pregnancy but 3% is very high and unnecessary .You are likely to get adverse reactions such as stinging/redness and doubt you would pass RIPT safety test.We have used it up to 0.3%  which is borderline for sting etc, although I have seen it used up to 0.5-1%.

    If you’re just using retinol for marketing purposes, 0.2-0.5% is enough. If not, you can use it up to 1% only.

    Yes 3% it is the level of a retinol peel you will have severe side effects. I also think 0.25 is more than enough in a product for daily basis.

    You can’t use 1% retinol in formula. Is to much.
    The SCCS has estimated that exposure to Vitamin A (retinol, retinyl palmitate, and retinyl acetate): 
    - via hand cream at the maximum concentration of 0.3% may lead to daily systemic
    dose of 1661 IU for an adult. This exposure could constitute up to 33% of the UL of
    5000 IU/day of Vitamin A. Therefore, the SCCS considers that the use of Vitamin A in
    hand cream products per se is safe.

    - via face cream at the maximum concentration of 0.3% may lead to daily systemic dose of 1185 IU for an adult. This exposure could constitute up to 24% of the UL of 5000 IU/day of Vitamin A. Therefore, the SCCS considers that the use of Vitamin A in face cream products per se is safe. 
    - via rinse-off products at the maximum concentration of 0.3% may lead to a daily systemic dose of 408 IU for an adult. This exposure could constitute up to 8.8% of the UL of 5000 IU/day of Vitamin A. Therefore, the SCCS considers that the use of Vitamin A in rinse-off products per se is safe.

    The max I’ve seen on a leave on formula is 600.000 IU, more than that might be a prescription cream for specific purposes.

    Here is what the CIR has to say about Retinol (and Retinyl Palmitate).  Basically, it’s safe to use <1%.

    @Perry  Good post as I was looking for it but couldn’t find it.

    Now I come to find out the customer wants 3% “retinol or retinoid complex”.  Not straight retinol.  Now the fun begins trying to find out exactly what retinoid or retinol complex means.

    Using clever marketing, “retinol complex” could be anything you want.

    In case anyone runs into the same thing I have found a product by Wacker called “Cavamax W-8 Retinol Complex”.

    Some companies with a “complex” are actually using Retinol, retinyl palmitate, retinyl acetate combination.  Others may be using a Retinol 10S at 3% but that’s not really “active” amount.

    Skinmedica has a product they call “Retinol Complex 1.0”  IS that the percentage or merely a part of the name?  Ahh, have to love marketing.

    If your customer will accept 3 percent of retinol complex,Cavamax W 8 is 8 percent of active retinol in cyclodextrin. Sooo 3 percent of the complex provides 0.24 percent which is an effective level.We have used the product but did not do hydrolytic stability which is a concern but CD complex should help.

    Thanks DrBob.  My customer did agree to use 3% of the complex itself.  This is the best resolution as it greatly reduces the safety concern.

    It should be noted that some dermatologists and estheticians use 5-10% Retinol for peels, basically to get peeling effects and the effects or regular retinol use with less frequent applications. So depends who your customer is selling to.
