Best Vitamin C Serum For Face

Best Vitamin C Serum For Face In 2020

Vitamin C is alleged to have excellent properties for making the skin look healthier by tightening sagging skin and reducing the appearance of dark discolorations. But does it work? If so, which is the best vitamin C serum? Consider some of the following questions and answers when trying to decide whether to use vitamin C serum and which vitamin C serum product might be the best purchase for you.

​What Is Vitamin C Serum?

​Vitamin C Serum is a serum, or topical skin solution, made containing L-ascorbic acid. A solution made with less than 10% vitamin C will not be effective as a skin care treatment. The other main ingredients of a commercial vitamin C serum are typically oil and water, although the serum does not feel oily on the skin.

​Benefits of Vitamin C Serum

​Vitamin C is a natural free-radical fighter. Free radicals cause oxidation, which damages skin cells. The vitamin contains anti-oxidants, which do they opposite. They fight oxidation, which repairs skin cells.

Anti-oxidants are used to give the skin a more youthful and healthy look. Regular application of vitamin C serum also helps reduce the appearance of acne scars. Users can increase the number of topic antioxidants in the vitamin C serum by choosing a serum that contains other antioxidants, such as vitamin E.

​The human body gradually begins to produce incrementally less collagen starting around the age of 40. Vitamin C helps the body produce more collagen naturally. Collagen is the protein that binds together the cells in the body.

By helping the body produce more collagen, vitamin C helps reduce the appearance of sagging skin and wrinkles. Using vitamin C serum can be used by younger people hoping to prevent wrinkles and dark spots on their skin or by older people looking to reduce the appearance of wrinkles and skin discoloration.

​Although vitamin C serum can’t be used as a substitute for sunscreen, it does help reduce damage caused by the sun by causing the skin to become slightly thicker and therefore less vulnerable to UV rays.

For the best skin protection from the sun, and to help prevent skin cancer, one should use a combination of vitamin C serum and a sunscreen with SPF protection. Vitamin C serum can also help reduce the appearance of minor redness caused by exposure to UV rays. Also, vitamin C serum can help undo the effects of exposure to air pollution.

​Some users prefer using a vitamin C serum to using a vitamin C cream for skin care because the serum does not feel heavy or greasy on the skin.

​Choosing the Right Vitamin C Serum

​Because pure vitamin C has a short shelf life and oxidizes relatively quickly, commercial vitamin C serums for skin care are made with alternative vitamin C formulas. Two common ones are magnesium ascorbyl phosphate and sodium ascorbyl phosphate. These are considered safe ingredients.

Formulas to avoid include ascorbyl palmitate (it may be labeled as vitamin C ester), tetra hexyl decyl ascorbate (also called ascorbyl tret ais palmitate), and liposome vitamin C. These three ingredients are all derived from ascorbyl palmitate, which is known to make skin sensitive to UV light.

​When one begins to use vitamin C serum for the first time, one can start by using a serum with a 10% concentration of vitamin C. After a few weeks, one can increase the percentage of vitamin C in the serum, up to 15 to 25%.

​Because vitamin C can oxidize quickly, and even more so when exposed to light and air, users may want to choose vitamin c serum products that come packaged in airtight, opaque containers.

​How to Use Vitamin C Serum

​Using a vitamin C serum is 20% more effective as a skin treatment than taking vitamin C tablets orally. Unfortunately, upping your citrus fruit intake won’t necessarily be beneficial for your skin. However, the body also needs dietary vitamin C, so the best course is to use vitamin C serum in addition to getting enough of the vitamin in one’s diet.

​To use a vitamin C serum correctly, rinse your face with water. Start by applying the serum to your neck and face. Give the serum some time to dry. When it’s dry, apply a moisturizer with some SPF protection. When not using the serum, store it in the refrigerator.

None of the products contain AHA, which some users reported a preference for, but OZNaturals' serum does contain vitamin E and astaxanthin for added antioxidant power. What sets this serum apart from the others is its high concentration of the oil ingredient, glycerine; users seem to prefer their vitamin C serums to feel “thick” rather than “watery,” and this serum seems to deliver the most satisfying feeling on the skin.​
