Vitamin C is one of the most potent anti-oxidants out there.

It is very well researched and can protect skin from free radical cell damage. It promotes collagen, which has the potential to thicken the skin.

It is a great anti-ageing ingredient that also brightens and prevents age spots. It is very important that you use your daily SPF when you use a Vitamin C in your routine, as this potent active ingredient can cause photosensitivity.

This is also one of those ingredients that you want to build up slowly in your routine to avoid irritation in the first weeks. If it’s a serum, mix it with your moisturizer the first week to let your skin get used to the active. In the second week, use it one day on, one day off. If no irritation occurs, you can start using it once or twice a day (followed up with your daily SPF when used in the morning)
