How to Choose Vitamin C Serum
There are several people who are looking forward to brightening their skins and repair free radical damage. Those who routinely use vitamin C serums in caring for their skins get so many benefits. But with so numerous products claiming they provide all the advantaged of vitamin C, how does one go about selecting the right one? Below are points to help you pick the best vitamin C serum.
You need to consider the form of vitamin C. There are different forms of vitamin C, for example, tetrahexyldecyl ascorbate, sodium ascorbyl phosphate, ascorbyl palmitate, and L-ascorbic acid, among more but they are not the same in terms of absorption rate and stability. It is essential that the vitamin C serum you choose be well formulated and has great bioavailability and penetration, that is, be able to go where it is needed to go and do what it is supposed to do. Most serums contain L-ascorbic acid but a number of experts consider tetrahexyldecyl ascorbate to be more active hence recommending it.
Check the concentration. Concentration is the strength of the acid in serums and vitamin C serums differ widely in concentration. For people with more sensitive skin, they should select serums of concentration of about 5% as more concentration can cause irritations. In case you want a heavier dose, you are going to see better results within a short duration the higher you go. However, some kind of a plateau is seen after 20% and you will notice results that are similar to those of twenty percent regardless of how higher the concentration is thus should not pay more.
You should check the formulation. Even though vitamin C offers a variety of advantages on its own, studies have shown that when combined with ingredients that are as powerful as it is, its efficacy increases. Combining vitamin C with ferulic acid and vitamin E makes a more potent antioxidant. Vitamin E acts as an antioxidant and enhances vitamin C function. Another antioxidant to keep your eyes on is Glutathione as it works well with vitamin C.
Ensure you check the price. A great formulation makes sure a product is bio-available and stable; two factors that are important in the manufacture of vitamin C serum. Serums with the correct formulation tend to be more expensive. However, price does not mean everything as some products of inferior quality cost more. Some of the most expensive serums may lack studies supporting their suitability and their formulation may be wanting. When buying vitamin C serum, you should seek advice from skin experts so that you do not save a penny only to end up with damaged skin.
Ensure you put the package into account. Serums packed in containers that expose them to light and clear containers are unstable and less usable hence should be avoided.
