Q: What is the most effective vitamin C Serum?

A: A good vitamin C serum can help to accelerate the skin’s ability to heal itself. This is especially great for helping to common skin conditions like acne scarring and sunburn. A vitamin C serum can provide a bit of relief from burning and itching and can even help to reduce the appearance of redness in the skin.

Q: What are the best vitamin C skin products?

A: It IS true that the best form of Vitamin C for skin is L-ascorbic acid because it’s the most bioavailable form. Other forms are often used in skin care products (usually palmitate) and are not quite as good. Palmitate is a salt or ester of palmitic acid which is naturally occurring in plants, animals and humans.

Q: When is it best to use vitamin C Serum?

A: Some experts believe that vitamin C skin care products should be applied at night in order to help skin repair itself while other sleep-restorative functions are taking place. Some believe that it should be applied during the day in order to help fight off free-radical damage as it accumulates through the day.
