A recommendation for a good Vitamin C serum?

I was wondering if you could recommend a good Vitamin C serum that I could purchase in Canada. Can I use a moisturizer with the C serum. I use Retin A at night and was considering using a c serum and moisturizer in the morning. I am 54 years old. Thanks

The SkinCeuticals (try the Phloretin CF or the AOX 20, the C&E Ferrulic is probably the best but a little more irritating) and Cellex-C serums are excellent.  They can be a little sticky under makeup which bothers some people.  Try the SkinMedica Vitamin C if you think that might bother you.  Put your sunscreen or moisturizer over it.

Use the 20% if you’re skin is NOT easily irritated and try the 10% if it is.  The 10% can still be too strong for some in which case try going with the Replenix green tea 90% polyphenol cream.  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!
