If there was a celebrity list for serums, there’s no doubt that Vitamin C would be an A lister. Everyone is talking about Vitamin C these days with good reason; applying Vitamin C onto your skin in a serum form is one of the most effective ways of soaking up all its goodness. The list of benefits run the gauntlet for everything that anyone could ever want in a serum:\n\nPotent antioxidant and protector? Check. Vitamin C helps fight and neutralize free radicals, protecting the skin from environmental stress such as sun damage and air pollution. \nEvens out skin discoloration and hyperpigmentation? Check. Vitamin C inhibits melanin synthesis which can cause uneven skin tone.\nHelps heal and prevent acne? Check. Vitamin C has strong anti-inflammatory properties to fight blemishes. \nMinimizes wrinkles and fine lines? Check. Vitamin C stimulates collagen production which counteracts the visible signs of aging. \n\nYes! Apply Vitamin C Serum in the Morning:\nTurns out a glass of orange juice, along with 2-3 drops of Vitamin C serum for your face is a great way to start the day and get your morning glow-on! Vitamin CEF is best for daytime use with its high concentration of L-ascorbic acid to ward off the effects of the sun and other environmental stressors. In addition, applying a potent serum like 20% Vitamin C + E Ferulic Acid, may actually boost your sunscreen protection. According to the Linus Pauling Institute at Oregon State University, while it’s not recommended that Vitamin C should actually replace sunscreen, applying topical Vitamin C can boost your protection against sun damage, especially when Vitamin C is combined with these two additional antioxidants, Ferulic Acid and Vitamin E. \nBut Not all Vitamin C Serums are Equal: \nA skincare regimen that includes Vitamin C serum can help fight the effects of aging and give your skin a vibrant glow. L-Ascorbic Acid is the most pure, potent and easily absorbed by the skin, but it is also the least stable form of Vitamin C and can cause irritation for sensitive skin. \nFor the highest efficiency and longest shelf-life look for the following when it comes to using a Vitamin C serum with L-Ascorbic Acid: \n\nIncludes Vitamin E and Ferulic Acid that help to stabilize and enhance the function of Vitamin C.\nAn Opaque or amber-hued packaging to protect against sun degradation.\nAn Airless container to reduce oxidization. \n10% - 20% concentration of L-Ascorbic Acid for maximum effectiveness. \n\nIt’s Complicated- Applying a Vitamin C Serum at Night:\n‘Beauty sleep’ is really a thing, since the body switches into recovery mode as you sleep, healing and repairing itself. This is a great time to nourish the skin more deeply, using active ingredient serums and rich moisturizers. \nYes, you can certainly use a Vitamin C serum at night, which helps avoid any sensitivity that it may cause by day. But its important to take your night-time skincare regime into consideration. \n\nAHAs (such a glycolic and lactic acid) and BHAs (beta-hydroxy\/salicylic acid) with Vitamin C are traditionally not recommended, especially for dry or sensitive skin. The concern is that layering acids together can cause excessive redness, dryness and flakiness. \nFor an evening regime, when using products with ingredients such as an AHA\/BHA, prescription creams or peptides, a more stable vitamin C with hydrating benefits such as the HA Serum with Vitamin C, could prove to be more compatible in combination with other active ingredients.\n\nThere are also many Vitamin C derivatives that are not as, but also more stable, such as Magnesium Ascorbyl Phosphate in the Timeless Hyaluronic Acid + Vitamin C serum. “The Essential”, HA and Vitamin C Serum, is less concentrated and is great for more sensitive or oily skin since it does not contain Vitamin E. It’s also great if you want to use more than 1 active ingredient serum in the same skin care regimen, especially at night.
