Vitamin C Serum is a derivative of pure vitamin C that stimulates collagen production, restores and regenerates the skin, anti-aging, improves uneven skin tone. Choose the right vitamin C serum product, use it regularly, regularly and properly to help bring higher efficiency.

Vitamin C is an antioxidant, which means it works to block environmental and sun damage to body cells. The best way to get the benefits of vitamin C is to apply it directly to the skin.
Most users do not like to apply vitamin C-rich fruit directly on the face. When you do it yourself, there's no control over the quality - and sometimes, it's not even safe. It's also not effective.
That's because when we eat, drink or take a vitamin C supplement, also known as ascorbic acid, our skin only gets a small amount into it. However, squeezing vitamin C into liquid form, after many chemical transformations, actually allows our skin to absorb more vitamin C effectively.

Reduces wrinkles Protects and boosts collagen production Supports wound healing Helps fight sun damage Reduces pigmentation Improves skin color imbalances Brightens skin Acts like an armor against infection and other free radicals.

Vitamin C serum should be applied after cleansing and toning. One study recommends that users apply a vitamin C serum every 8 hours, or twice a day, for peak protection.
Vitamin C has the property of eliminating oxidative stress from the free radicals that we encounter every day. They come from car exhaust, cigarette smoke, certain chemicals, and even alcohol and overly processed foods.
Unlike sunscreen, moisturizer, or oil, vitamin C can be wiped off or washed off easily.
Vitamin C's protection and free radical fighting power will wear off over time, but you can develop a plan to get enough vitamin C to help keep your skin healthy. This can be achieved by applying every 8 hours.
Also, UV light reduces the vitamin C level of the skin. Topical vitamin C is best applied after UV exposure, not before.

10 - 20% L-ascorbic acid Vitamin E and ferulic acid Sealed packaging A dark or colored glass bottle.

Product name: L-ascorbic acid. Vitamin C can appear on the ingredient label under a number of different names, with L-ascorbic acid products being the most effective.
Concentration: 10 - 20 %. Exceeding 20 % may lead to discomfort and will not increase the usefulness of use.
Combination ingredients: L-ascorbic acid, tocopherol (vitamin E) or glutathione, ferulic acid. Look for both vitamin C (L-ascorbic acid) and vitamin E (tocopherol) in the ingredients list.
Stable vitamin E will help vitamin C reach the maximum level of skin protection. Another antioxidant called glutathione is also a substance that combines well with vitamin C to increase the protective effect of the skin.
Test for ferulic acid, reduce the pH of vitamin C below 3.5% so that the skin can easily absorb vitamin C serum.
Packing: Dark or colored glass bottles, vacuum environment.
Exposure to air, light, and heat can degrade a vitamin C serum. Look for a dark glass bottle, dropper, rather than a spray.
Some retailers suggest storing the product in the refrigerator to extend its shelf life. Reputable brands will have instructions on the label on how to store and store the serum.
Price: Based on factors such as concentration and formula determine the quality of vitamin C serum. The price of a serum ranges from $25 to more than $100.

The combination of vitamin C with other specific ingredients, like vitamin E and ferulic acid, will help increase stability and allow for good absorption by the skin.
Therefore, making your own serum often does not bring the same results as buying a pre-made serum. However, if you are a fan of homemade products, you can use a serum of your own with all the necessary ingredients.
No matter what brand and form you buy, the bottom line about vitamin C - the best ingredient for skin with many studies proven. You should rely on the vitamin C content in the product rather than on the price to buy when choosing to buy.
