Ideal concentration is 10-20% especially stubborn pigmentation, normal or oily skin but if you have dry,or sensitive skin, a lower percentage is advisable.
SPF should be worn with the combination of vitamin C for daytime use.
Sodium Ascorbyl Phosphate
This ingredient is great for all skin types but it is less intense. It is a mineral form sometimes referred to as "Vitamin C Salt" where it converts into Ascorbic acid when applied to the skin.
Behaves less erratically than Ascorbic acid when exposed to light and air.
This form of vitamin C is less irritating for sensitive or reactive skin which allows for stronger concentration in the formula.
It must be combined with liquid ingredients to topically applied to skin.
Magnesium Ascorbyl Phosphate (MAP)

greater stability that L-Ascorbic acid, a form of vitamin C that easily penetrates the skin. Ascorbyl glucoside is a vitamin C with sugar glucose derived from natural starch such a s rice.
