Vitamin C is a very tricky and sneaky ingredient, as it can be found in different ascorbyl forms, concentrations. Depending on their formulation they can also be irritating for certain sensitive skins. In general, l-ascorbic acid, which is a form of Vitamin C used most in skincare formulations, should be avoided for sensitive skin or those with a compromised barrier function.
Our favourite types of Vitamin C for sensitive skin are:
Magnesium ascorbyl phosphate : It is a water soluble compound that is more stable in water & less potent than it’s cousin l-ascorbic acid. It doesn’t mean that it works “less” as this compound is significantly effective in lower concentrations. It doesn’t have the exfoliating effects that other forms of Vitamin C do.
Sodium ascorbyl phosphate: This one is also a water soluble derivative of ascorbic acid. It is believed to provide the same benefits as l-ascorbic acid, without the risk of oxidation and irritation. If your skin is sensitive due to acne or breakouts this is your go-to! There is some research showing amounts of 1% and 5% concentrations of sodium ascorbyl phosphate can influence factors linked to breakouts!
** Best for**: Reinforcing the skin and protecting it from environmental damage. It’s been shown to work in synergy with the antioxidant Vitamin E!
