Vitamin C - one of the products most coveted skin care - addresses the lack of glare, dark spots and skin elasticity.
You may realize that it is not working for you if you have the opposite of the benefits of vitamin C placement, or you do not notice any change after long use.
Some possible reasons why a product is not working are:
- has expired
- is located in a sunny or humid place
- does not have enough active ingredients
- is of poor quality
But, if you are sure that there is none of the above alternatives, it is likely that the product you have chosen is not suitable for your skin. There are several brands of vitamin C and its various forms.
If you have sensitive skin, avoid vitamin C products with L-ascorbic acid as it may cause irritation. Instead, use magnesium sorbent phosphate, a water-soluble derivative of vitamin C, which is softer on the skin.
