Vitamin C can work to strengthen collagen and elastin in the deepest layers of the skin. As collagen fibrils have excellent moisture binding properties, this is a good way of locking moisture into the skin, producing moisturized and supple skin.
However, Vitamin C, or L-ascorbic acid, is very unstable and breaks down when exposed to air or sunlight. This means that it may loose some of its effectiveness when used in creams or moisturizers.
Using Vitamin C And Dry Skin Care Products
Here are some pointers for you to remember when using vitamin C to care for your skin.
1) You can use a Vitamin C cream under your regular moisturizer.
2) Although vitamin C can protect your skin against sun damage, it is not the same as a sunscreen, so never use it alone only.
3) Eating foods rich in Vitamin C can be helpful in caring for your skin, so make sure you eat plenty of citrus fruits as part of your Vitamin C skin care routine.
If you have dry and sensitive skin, products containing Vitamin C may be too harsh and acidic for your skin type.
In such cases, alternatives such as Vitamin C derivatives ascorbyl palmitate and magnesium ascorbyl phosphate would suit you better. These two substances are found to be safer for you to use.
