For a vitamin C serum to be effective, dermatologists say there are a few key things to consider:<\/p>\n<p>Type of vitamin C: According to our experts, the vitamin C type will also determine its effectiveness. Pure vitamin C, known as L ascorbic acid, is the most effective antioxidant when formulated correctly. But this is also the most irritating form, making it less than ideal for <a href=\"https:\/\/www.nbcnews.com\/select\/shopping\/best-sensitive-skin-products-ncna1303313\" target=\"_blank\" rel=\"nofollow noopener\">sensitive skin<\/a>. Other forms of vitamin C are slightly less effective but gentler, including sodium ascorbyl palmitate (a fat-soluble molecule often found in creamier skin care products), and tetrahexyldecyl ascorbate (an oil-based form of vitamin C that penetrates skin deeply and is less irritating). Vitamin C products must be formulated at a low pH level (between 2.5 and 3.5) to effectively penetrate the skin, which some brands will list on the packaging. (Products with a low pH level are slightly acidic, which is one reason vitamin C can irritate. If you have sensitive skin, introduce a low-pH product slowly.) Concentration: Most vitamin C serums on the market are formulated with a concentration between 10% and 20%. \u201cBeyond that, it\u2019s just irritating and not necessarily more effective,\u201d says Castilla.<\/p>\n<p id=\"anchor-9c8d25\" class=\"body-graf\">Want more from NBC Select? <a href=\"https:\/\/link.nbcnews.com\/join\/5cj\/nbc-news-select-signup-pd\" target=\"_blank\" rel=\"nofollow noopener\">Sign up<\/a> for our newsletter, The Selection, and shop smarter.<\/p>\n<p><a href=\"http:\/\/www.nbcnews.com\/select\/shopping\/best-vitamin-c-serums-rcna240620#anchor-ba541a\" id=\"anchor-ba541a\" class=\"scrollLink\" rel=\"nofollow noopener\" target=\"_blank\">The best vitamin C serums in 2025<\/a><\/p>\n<p id=\"anchor-dcaf80\" class=\"body-graf\">To get the antioxidant benefits of vitamin C in your <a href=\"https:\/\/www.nbcnews.com\/select\/shopping\/best-skin-care-routine-rcna105133\" target=\"_blank\" rel=\"nofollow noopener\">skin care routine<\/a>, experts recommend looking for a serum with a concentration between 10% and 20%.

It\u2019s often referred to as the gold standard in vitamin C serums by dermatologists. \u201cIt probably has the most evidence behind it,\u201d says Castilla, referring to the clinical studies conducted by the brand that show a 41% reduction in oxidative damage in the skin. It\u2019s also one of the more stable formulas on the market, thanks to the inclusion of vitamin E and ferulic acid, according to <a href=\"https:\/\/smarterskindermatology.com\/about-us\/\" target=\"_blank\" rel=\"nofollow noopener\">Dr. Sejal Shah<\/a>, board-certified dermatologist and founder of SmarterSkin Dermatology in New York. \u201cThis combination makes vitamin C more potent,\u201d says Ilyas, and helps prevent the L-ascorbic acid from oxidizing before it can reach your skin. <\/p>\n<p id=\"anchor-bf705a\" class=\"body-graf\">\ufeff<a href=\"https:\/\/www.nbcnews.com\/author\/lindsay-schneider-ncpn1303947\" target=\"_blank\" rel=\"nofollow noopener\">Lindsay Schneider<\/a>, NBC Select commerce editor, says that when using this serum, she genuinely feels like it makes her skin look healthier, brighter and better. The one caveat our experts call out is the packaging: the dropper bottle means this serum is exposed to more air. According to the brand, however, the formula should remain stable and effective for up to six months after it\u2019s opened. <\/p>\n<p><a href=\"http:\/\/www.nbcnews.com\/select\/shopping\/best-vitamin-c-serums-rcna240620#anchor-e8dabb\" id=\"anchor-e8dabb\" class=\"scrollLink\" rel=\"nofollow noopener\" target=\"_blank\">Best for dry skin<\/a><a href=\"https:\/\/www.amazon.com\/Sunday-Riley-Vitamin-Brightening-Serum\/dp\/B074JXVVW3?tag=bestvitamincserumsrcna240620-20\" data-product-id=\"rcpd21952\" data-testid=\"product-picture-link\" data-aps-asc-tag=\"bestvitamincserumsrcna240620-20\" data-aps-asin=\"B074JXVVW3\" rel=\"sponsored noopener noreferrer nofollow\" target=\"_blank\" class=\"w-100\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2025\/10\/AMAZON-0c20f7.jpg\" alt=\"Sunday Riley C.E.O. 15% Vitamin C Brightening Serum\" height=\"500\" width=\"500\"\/><\/a><\/p>\n<p>Skin type: all\u00a0| Key ingredients: saccharide isomerate extract, glycolic acid, vitamin C (THD ascorbate)<\/p>\n<p>What we like<\/p>\n<p>Creamy consistencySkin appears plump and firmEvens tone and texture<\/p>\n<p id=\"anchor-70766c\" class=\"body-graf\">Former NBC Select associate reporter <a href=\"https:\/\/www.nbcnews.com\/author\/bianca-alvarez-ncpn1306070\" target=\"_blank\" rel=\"nofollow noopener\">Bianca Alvarez<\/a> is a huge fan of this serum, which she says has a creamy, lotion-like consistency that she loves for her <a href=\"https:\/\/www.nbcnews.com\/select\/shopping\/best-moisturizers-dry-skin-ncna1287507\" target=\"_blank\" rel=\"nofollow noopener\">dry skin<\/a>. \u201cThis is by far my absolute favorite vitamin C option I\u2019ve tried,\u201d she says.

Below, we summarized the most convincing benefits, according to our experts: <\/p>\n<p>Vitamin C helps protect your skin from sun and other harmful substances. \u201cThe most convincing evidence we have for vitamin C [in skin care] is the prevention of free radical damage,\u201d says Castilla. In scientific terms, free radicals are molecules with an unpaired electron, making them unstable and capable of damaging cells. Antioxidants like vitamin C neutralize those radicals by donating an electron, according to Castilla. Sunlight is a common source of free radical exposure as is the pollution your skin is exposed to every day, says Shah. That exposure can \u201caccelerate skin damage and aging through what we call oxidative stress,\u201d she says. Vitamin C protects skin, preventing the breakdown of collagen and elastin. It\u2019s effective at reducing hyperpigmentation. Vitamin C can also protect your skin from unwanted dark spots. \u201cIt inhibits an enzyme called tyrosinase in the skin to <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC5579659\/\" target=\"_blank\" rel=\"nofollow noopener\">reduce hyperpigmentation<\/a>,\u201d says Ilyas. It works best as a treatment for dark spots caused by sun damage and conditions like <a href=\"https:\/\/www.nbcnews.com\/select\/shopping\/best-melasma-treatments-rcna98546\" target=\"_blank\" rel=\"nofollow noopener\">melasma<\/a>, she says. \u201cNot all pigment is the same and I do not always find that acne scars respond consistently as well to vitamin C,\u201d she says.  Vitamin C can help reduce redness. Inflammation is often the culprit behind skin redness and dryness. Vitamin C can help treat these issues by inhibiting a pro-inflammatory signaling molecule, says Castilla. It can boost your skin\u2019s collagen production. Your skin needs vitamin C to produce <a href=\"https:\/\/my.clevelandclinic.org\/health\/articles\/23089-collagen\" target=\"_blank\" rel=\"nofollow noopener\">collagen<\/a>, the primary building block for skin and other connective tissues, that\u2019s responsible for skin elasticity and firmness. \u201c<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC5579659\/\" target=\"_blank\" rel=\"nofollow noopener\">Collagen hydroxylase<\/a>, an enzyme in the skin that is responsible for collagen formation, is dependent on Vitamin C to function,\u201d says Ilyas. <a href=\"http:\/\/www.nbcnews.com\/select\/shopping\/best-vitamin-c-serums-rcna240620#anchor-80ac96\" id=\"anchor-80ac96\" class=\"scrollLink\" rel=\"nofollow noopener\" target=\"_blank\">How to shop for a vitamin C serum<\/a><\/p>\n<p id=\"anchor-6c2ae9\" class=\"body-graf\">Not all vitamin C skin care products are created equally. You\u2019ll often see vitamin C skin care products in acid form \u2014 at specific concentrations, though, it can be irritating, especially for sensitive skin. Vitamin C is also a highly unstable ingredient, according to experts \u2014 the same chemical properties that allow it to work as an active antioxidant in your body also make it susceptible to oxidation, which will make it inactive in your skin. That\u2019s why our experts recommend using it in the form of a serum, as they are lightweight and easy to layer with other products. <\/p>\n<p id=\"anchor-4e6340\" class=\"body-graf\">To get the most out of your serum, they recommend understanding the type and concentration of vitamin C in any formula, being mindful of how packaging can impact a serum\u2019s effectiveness, and looking for companion ingredients that support the skin barrier. <\/p>\n<p><a href=\"http:\/\/www.nbcnews.com\/select\/shopping\/best-vitamin-c-serums-rcna240620#anchor-bedf3d\" id=\"anchor-bedf3d\" class=\"scrollLink\" rel=\"nofollow noopener\" target=\"_blank\">Type of vitamin C<\/a><\/p>\n<p id=\"anchor-344296\" class=\"body-graf\">You\u2019ll commonly find vitamin C incorporated into a topical product in two ways: in its active form as L-ascorbic acid, or in an inactive form that needs to convert into L-ascorbic acid on the skin, says Shah. <\/p>\n<p id=\"anchor-5fec43\" class=\"body-graf\">In controlled settings, L-ascorbic acid is the most effective, says Castilla, but in reality the effectiveness of a vitamin C serum may depend on a variety of factors, including your skin type. \u201cL-ascorbic acid can be very unstable so whatever bottle that you get, you have to use it very quickly or it will oxidize,\u201d she says. \u201cSecondly, it has to be formulated at a low pH, meaning it\u2019s very acidic and it can be very irritating for a lot of skin types, especially <a href=\"https:\/\/www.nbcnews.com\/select\/shopping\/best-skin-care-products-rosacea-ncna1299897\" target=\"_blank\" rel=\"nofollow noopener\">rosacea-prone<\/a> skin types.\u201d<\/p>\n<p id=\"anchor-ec6919\" class=\"body-graf\">Other types of vitamin C \u2014 such as 3-O-ethyl ascorbic acid, sodium ascorbyl phosphate, and tetrahexyldecyl ascorbate \u2014 are more stable. Shah particularly likes tetrahexyldecyl ascorbate since it converts to L-ascorbic acid really well and also penetrates the skin really well, she says.<\/p>\n<p><a href=\"http:\/\/www.nbcnews.com\/select\/shopping\/best-vitamin-c-serums-rcna240620#anchor-988b7b\" id=\"anchor-988b7b\" class=\"scrollLink\" rel=\"nofollow noopener\" target=\"_blank\">Concentration <\/a><\/p>\n<p id=\"anchor-36af21\" class=\"body-graf\">The dermatologists we spoke to recommend looking for products with a concentration of vitamin C between 10% and 20%. \u201cBeyond 20%, it\u2019s just irritating and not necessarily more effective,\u201d says Castilla. <\/p>\n<p><a href=\"http:\/\/www.nbcnews.com\/select\/shopping\/best-vitamin-c-serums-rcna240620#anchor-b2a684\" id=\"anchor-b2a684\" class=\"scrollLink\" rel=\"nofollow noopener\" target=\"_blank\">Packaging <\/a><\/p>\n<p id=\"anchor-31d11a\" class=\"body-graf\">Exposure to light and air are disastrous for the unstable molecules found in vitamin C serums, according to our experts. \u201cWhat vitamin C does for free radicals is contribute electrons to the free radicals [to stabilize them],\u201d says Castilla. \u201cOnce that happens, then the vitamin C is no longer active.\u201dWhen vitamin C molecules are exposed to oxygen, \u201cit loses those electrons and it becomes an inactive form of vitamin C,\u201d she says. <\/p>\n<p id=\"anchor-79d402\" class=\"body-graf\">Packaging and the way you store your serum are key to its effectiveness. Ilyas recommends serums in opaque or amber colored glass bottles, which block light exposure. And while many top vitamin C serums come in a glass bottle with a dropper, Castilla says those with airless pump bottles will stay active longer. Store your serum away from the sun and don\u2019t hoard it \u2014 this unstable ingredient is best used quickly. <\/p>\n<p><a href=\"http:\/\/www.nbcnews.com\/select\/shopping\/best-vitamin-c-serums-rcna240620#anchor-af18df\" id=\"anchor-af18df\" class=\"scrollLink\" rel=\"nofollow noopener\" target=\"_blank\">Companion ingredients<\/a><\/p>\n<p id=\"anchor-203594\" class=\"body-graf\">\u201cMany worthy topical vitamin C-containing serums will often be combined with ferulic acid and vitamin E because this combination can increase the effectiveness of vitamin C,\u201d says Ilyas. <\/p>\n<p id=\"anchor-d206ba\" class=\"body-graf\">Castilla also recommends pairing your vitamin C with <a href=\"https:\/\/www.nbcnews.com\/select\/shopping\/how-shop-sunscreen-ncna1305708\" target=\"_blank\" rel=\"nofollow noopener\">sunscreen<\/a>. \u201cSunscreens help block free radical damage, but not all of it,\u201d she says. \u201cPairing sunscreen with a vitamin C doesn\u2019t improve the UVA\/UVB protection, but [the vitamin C] protects against the free radicals that are being produced.\u201d<\/p>\n<p>Frequently asked questions<\/p>\n<p>Is vitamin C suitable for all skin types?<\/p>\n<p>\u201cVitamin C is a safe and reasonable product for most skin types,\u201d says Ilyas, but how and when you add it to your <a href=\"https:\/\/www.nbcnews.com\/select\/shopping\/best-skin-care-routine-rcna105133\" target=\"_blank\" rel=\"nofollow noopener\">skin care routine<\/a> depends on your skin type and the type of vitamin C you choose. Ilyas usually recommends using vitamin C starting in your 30s because that\u2019s when pigmentation changes associated with light exposure tend to reveal themselves, she says. <\/p>\n<p>If you have sensitive skin, Castilla recommends looking for a formula made with a vitamin C derivative like sodium ascorbyl phosphate or tetrahexyldecyl ascorbate to avoid irritation. <\/p>\n<p>Should you use vitamin C in your morning or evening skin care routine?<\/p>\n<p>You can use a vitamin C serum in either y our morning or evening routine, though most formulations are meant for morning use, says Castilla. When you apply it in the a .m., vitamin C can help fight free radical damage from UV light and the other oxidative stressors your skin is exposed to during the day. If you want to use vitamin C serum twice a day, she recommends sticking with a formula with a lower concentration (10% to 15%) to avoid irritation. <\/p>\n<p id=\"anchor-0108fe\" class=\"body-graf\">\ufeff<\/p>\n<p><a href=\"http:\/\/www.nbcnews.com\/select\/shopping\/best-vitamin-c-serums-rcna240620#anchor-d64cc1\" id=\"anchor-d64cc1\" class=\"scrollLink\" rel=\"nofollow noopener\" target=\"_blank\">Meet our experts<\/a><\/p>\n<p id=\"anchor-990b65\" class=\"body-graf\">At NBC Select, we work with experts who have specialized knowledge and authority based on relevant training and\/or experience.
