If you\u2019re looking to achieve that perfect dewy complexion, look no further to find out what it can do for you.<\/p>\n<p>What is vitamin C serum good for? Let\u2019s explore.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_are_Vitamin_C_Serums\"><\/span>What are Vitamin C Serums?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Vitamin C is a powerful antioxidant that\u2019s getting rave reviews by skincare enthusiasts as a wonderful anti-aging ingredient in topical products such as serums. <\/p>\n<p>As a nutrient, vitamin C is essential to:<\/p>\n<ul>\n<li>Building proteins used to form skin, ligaments, tendons, and other parts of the body<\/li>\n<li>Repairing tissue and healing wounds<\/li>\n<li>Blocking free radical damage from exposure to things like radiation or pollutants<\/li>\n<\/ul>\n<p>Since it\u2019s a water-soluble vitamin, vitamin C leaves your body quickly when ingested. Your skin has a hard time getting any of the benefits from your diet alone because it doesn\u2019t have blood vessels to deliver nutrients to skin cells. Adding more vitamin C-rich foods to your diet sadly isn\u2019t going to be enough to give you that perfect glowing complexion.<\/p>\n<p>That\u2019s why applying vitamin C to the skin through a serum is seen as a fantastic way for your skin to soak up all the benefits directly. Let\u2019s take a look at what some of those benefits are.has <\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_are_the_Benefits_of_Vitamin_C_Serums\"><\/span>What are the Benefits of Vitamin C Serums?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>So what does vitamin C serum do for skin that makes it the talk of the beauty world? There are many potential benefits of adding this serum to your daily routine you can check off, including:<\/p>\n<ul>\n<li>\n<p><strong>Boost Collagen Growt<\/strong>h \u2013 Collagen is a protein that firms up the skin and keeps it from sagging. Vitamin C can help stimulate collagen growth.<\/p>\n<\/li>\n<li>\n<p><strong>Anti-Aging<\/strong> \u2013 With Vitamin C, you can take preventative measures and reduce premature wrinkling.<\/p>\n<\/li>\n<li>\n<p><strong>Protection from Sun Damage<\/strong> \u2013 In conjunction with sunscreen, vitamin C can help protect against damage from sun exposure and soothe sunburns.<\/p>\n<\/li>\n<li>\n<p><strong>Fade Hyperpigmentation<\/strong> \u2013 Hyperpigmentation (such as from acne scars, sun spots, or age spots) comes from overactive melanin production. Vitamin C can slow that down and fade some spots out.<\/p>\n<\/li>\n<li>\n<p><strong>Skin-Brightening<\/strong> \u2013 Along with the evening out of hyperpigmentation, vitamin C can brighten up your skin and give it that fresh-faced glow of youth.<\/p>\n<\/li>\n<li>\n<p><strong>Reduce Redness<\/strong> \u2013 Skin inflammations can be soothed by the ingredients in vitamin C serums.<\/p>\n<\/li>\n<li>\n<p><strong>Say Goodbye  to Your Eyebags<\/strong> \u2013 Too many late nights? Vitamin C serums can help hydrate and firm up the dark circles under your eyes.<\/p>\n<\/li>\n<\/ul>\n<p>The science behind what nutrients can do for us and our bodies is constantly growing, but vitamin C has a high safety profile. You can learn more about what vitamin C does for the skin elsewhere on our blog, or by speaking with a dermatologist.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_to_Incorporate_Vitamin_C_Serums_into_Your_Skincare_Routine\"><\/span>How to Incorporate Vitamin C Serums into Your Skincare Routine<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>With so many outstanding benefits to offer, let\u2019s figure out how to introduce vitamin C serums into your self-care routine for maximum effect. <\/p>\n<p>Serums have a liquid or gel-like consistency and are usually applied once or twice a day. Consult the label on your product for specific instructions, but in general you\u2019ll want to apply a few drops after you cleanse your face.<\/p>\n<p>Then, apply a layer of moisturizer to lock it all in. An additional layer of sunscreen in the day will also help the serum do its job in preventing sun damage.<\/p>\n<p>Vitamin C as a skincare ingredient can come in a few different derivative forms, but here are the three you should look for when researching serums:<\/p>\n<ul>\n<li>L-ascorbic acid<\/li>\n<li>Ascorbyl-6 palmitate<\/li>\n<li>Magnesium ascorbyl phosphate<\/li>\n<\/ul>\n<p>L-ascorbic acid is the most active of these derivatives, and has the most research behind it according to a 2017 study published in The Journal of Clinical and Aesthetic Dermatology. Essentially vitamin C in its purest form, a serum with l-ascorbic acid can be a highly effective option.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"For_Those_with_Sensitive_Skin\"><\/span>For Those with Sensitive Skin<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In general, vitamin C serums are compatible with most skin types, but those with sensitive skin may experience minor irritation. It\u2019s always a good idea to do a patch test on an unobtrusive spot like your arm beforehand to make sure you don\u2019t have an allergic reaction to it. <\/p>\n<p>If you do have sensitive skin, L-ascorbic might not be the option for you due to its acidity. The best vitamin C serum for sensitive skin should be gentle on the skin. Try a serum with magnesium ascorbyl phosphate instead.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Brighten_Your_Skin_and_Your_Day_with_RebateKey_Savings\"><\/span>Brighten Your Skin and Your Day with RebateKey Savings<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Serums, like many skincare products, can fall into a wide range when it comes to price point. <\/p>\n<p>Whether you decide to splurge with a luxury brand or opt for a more affordable, no-nonsense option, never pay full price with RebateKey.
