Why Is Vitamin C The Latest Hero Ingredient In Skincare? – ELLE
When it comes to skincare, vitamin C can come in a number of forms, including liquid, powder or crystal. Powdered formulas tend to extend the shelf life of the products. “Some companies make vitamin c in crystal form because, vitamin C can oxidise when it gets exposed to air,” Dr Hkeik explains. “However, if it’s it in a crystal form, you can just add it last minute, mixing a spoonful into one of your serums and this prevents it from oxidising.”
Often, vitamin C products need to be introduced to your skincare regime gradually, to ensure your skin doesn’t react. Once you’re sure you skin can handle a smattering of vitamin C, apply up to twice daily—morning and night.
