Which order is the best for products?

Hi Dr. Irwin You recommend that you use Retin A after your moisturizer. Does the Vitamin A penetrate the skin as well as it would if you used it first and can you use a Vitamin C moisturizer in combination with the Retin A? I was also wondering if it was safe to use the Retin A around the eye area? Thanks

Yes with a couple of adjustments!   You can’t use a Retin A gel over a moisturizer but it works with the creams.  Put a light layer of moisturizer on –  WAIT 10 minutes –  and then apply the Retin A/Renova/tretinoin.    It works fine and is much less irritating.  It’s also fine to use your Retin A on your crow’s feet area.  Don’t put it on the eyelid skin itself.  Use your Vitamin C serum in the morning.   Hope this helps!  Dr. I

One of the best investments in your skin is your daily skincare. Why? Because you can prevent many problems with blotchy skin color, lack of glow, texture, some types of acne, and fine lines with good skincare products. You can also correct some of these problems with effective skincare products. Great skincare is often more expensive because quality ingredients are expensive. Some companies spend on research/development which benefits all of us and adds to the cost. Are they worth it? In general - yes!
