What We Like Absorbs quickly into the skin Wears well underneath makeup and doesn’t pill No sticky residue What We Don't Like Product can build-up in the dropper Strong fragrance Might cause skin irritation or breakouts If you’re looking for an affordable vitamin C serum that will hydrate the skin and absorbs well, this is a great product to incorporate into your daily skincare routine. We put the InstaNaturals Vitamin C Serum to the test after receiving a complimentary sample from the brand. Keep reading for our full product review. Dermatologists can’t rave enough about vitamin C serums and there’s good reason for it. From brightening your skin to helping in reducing dark spots and uneven texture, vitamin C serums have been widely used in daily skincare routines and aren’t going away anytime soon. If you’re in the market for a new vitamin C serum or you’ve never tried it for yourself, we’ve tested one of the most popular and affordable serums out there, and the results are absolutely worth testing it out for yourself. Ahead—our real thoughts on InstaNaturals Vitamin C serum and all the reasons why it might be worth space in your skincare regime. About My Skin I'm a daily vitamin C user I have combination and sensitive skin with type 1 rosacea. I use a vitamin C serum every single morning after cleansing and before sunscreen. I don’t have any texture issues at the moment, but it’s important for me to continue to protect my skin at all costs and help brighten up my complexion. The most notable vitamin C serum I’ve used in the past is Skinceuticals C E Ferulic Acid Serum. One of the greatest attributes of the serum is how well it wears under makeup and it absolutely doesn’t pill. My skin looked hydrated and bright, which are two incredible results. Byrdie / Ashley Rebecca How To Apply Pat it in with your fingers After cleansing you’ll want to dispense a dropper full on the palms of your hands and pat all over the face and neck if you choose until the serum is absorbed. While a lot of people tend to rub skincare products in, you can also choose to do that if you’re more comfortable with it. I will say that patting the serum helps the skin to absorb it well. Wait until the serum has fully dried before moving onto your moisturizer. If you only want to wear the serum, it’s best practice to follow up with sunscreen as your last step. Byrdie / Ashley Rebecca The Results My Skin Felt Hydrated A few things I noticed after applying the serum were how quickly it absorbed into my skin and that it wasn’t sticky or greasy. I am not the biggest fan of strong fragrance in my skincare products, so it’s important to keep in mind this serum does have fragrance for anyone who might be sensitive. There are some days that I applied makeup right after the serum, and others that I applied sunscreen and then my makeup to test out how well it worked with foundation and concealer. Byrdie / Ashley Rebecca The Value Too good to be true For the ingredients this serum contains and how well it wears on the skin, the price of $22 feels almost too good to be true. It’s an incredible value for the results it gives and is incredibly budget-friendly for skincare making it a total win in our book.

People / Kristin Kempa Vitamin C is one of the most searched skincare ingredients on the ‘net.

Why you ask? Firstly, the science and clinical testing behind the brand's products In this serum's cases, it's patented and clinically proven to reduce combined oxidative damage from free radicals generated by UV, Ozone, and diesel exhaust by up to 41 percent. Additionally, the serum improves signs of photodamage, lines, and wrinkles while brightening the skin and even fading dark spots. Though this didn’t earn our highest score — it was close at — we found that this product is worth the hype. Not only is it brightening and glowifying, but it smoothes fine lines and texture on our skin. We do want to call out that our tester, who has used vitamin C daily in her morning routine for eight years, wasn’t expecting a notable difference.

Our tester absolutely loved this product and said she will continue to use it at home until she uses the very last drop. She did note that the packaging can be tricky because while it's securely packaged for delivery, there are a few steps to opening the cap that took a second to figure out. But her acne-prone skin with post-breakout hyperpigmentation saw a reduction in the appearance of those spots while the formula felt light on the skin.

The brand's proprietary C-Firma is designed to be mixed by you before its first use. This helps maximize potency and keep the antioxidant complex of the L-ascorbic and ferulic acids fresh; each bottle is proven to maintain almost 95 percent efficacy up to one year after mixing. As for real-world results, we found that our skin was softer and plumper by the end of the six weeks, and our monthly chin breakouts were significantly reduced. One of our testers even started receiving compliments on her skin and said after three to four weeks of use, she'd catch herself in the mirror and think, "Wow, my skin looks so bright and smooth!" That self-confidence boost helps justify the price tag. However, this Drunk Elephant serum has a 15 percent vitamin C concentration, so if you're just starting out with a vitamin C step in your skincare routine, it's better to start with a 10 percent concentration.

Star ingredients 15% Vitamin C Ethyl Ascorbic Acid, PHAs, and hyaluronic acid People / Ivy Ford Things to Consider Before Buying Vitamin C Serum Concentration Level and Skin Type Most everyone can benefit from layering vitamin C into their routine. However, if your skin is reactive or sensitive, Chung says to avoid high-concentration formulas as they may cause irritation. So what exactly is a high dose? Formulas with 15-20 percent vitamin C are considered a higher dose. So, stick with a 10 percent concentration if this is your first experience with the antioxidant or if you have more reactive skin. You can always work your way up. Our top pick, L'Oreal Revitalift Vitamin C Serum, has a 10 percent vitamin C concentration. Other Ingredients Vitamin C is usually thoughtfully formulated with complementary ingredients. The reason for this? "Vitamin C products often need oiler vehicles to maintain stability," Chung tells PEOPLE. However, she notes this can be problematic for some skin types think acne-prone skin. But luckily, brand founders and chemists are considering a range of skincare needs. So if you are acne-prone, seek formulas with squalane and rosehip oils, as they are And as far as the actual vitamin C goes, Chung recommends products that use L-ascorbic acid as its active ingredient, preferably with vitamin E, for the best stability. This is because L-ascorbic acid is the most potent and effective form of vitamin C. Our best daytime serum, Drunk Elephant C-Firma Fresh Vitamin C Day Serum, contains both L-ascorbic acid and vitamin E. Retinol Products When should you apply vitamin C serum? That depends on what other products you’re using as well as your skin sensitivity level. Chung recommends her patients use Vitamin C in the morning. However, she tells us it can be applied at night with another skincare must-have "If I'm going to use either retinol or Vitamin C, I'll take retinol," she shares. However, Chung does note this pairing can be a dynamic duo that gets you a little more bang for your buck if your skin isn't prone to irritation. "Retinol is your gold standard for increasing collagen and improving the turnover of skin cells while Vitamin C acts as a supporting cast," she explains. Prone to irritation? No problem. Instead, stick with vitamin C for the daytime and retinol at To find the best vitamin C serums on the market, our team used them over a period of six weeks. We tested 32 vitamin C serums altogether on a variety of different skin types. Of the 32 serums tested, seven earned a or above, and the ratings ranged from a 2 to a We rated each serum on ease of application and absorption. Then we noted how it interacted with our skin texture and whether it produced a glow or had firming capabilities. We then gave it a general rating based on the overall look of the applied vitamin C serum. Finally, the prices were revealed and we compared the retail price against the quality of the product to get our value rating. All in all, we selected 13 vitamin C serums we feel confident would work well for a variety of people. Frequently Asked Questions How often should I use vitamin C? Darden says a slow start is best if you're starting a vitamin C serum for the first time or adding a new vitamin C serum you haven't tried. "Vitamin C is a very active ingredient, and it can cause irritation," she explains. "Introducing it slowly will allow time for your skin to acclimate to the product without causing any irritation. Additionally, adding the product in slowly and by itself will make it easier to pinpoint how well it works for your skin. If you're adding in too many products at the same time, it can make it difficult to understand whether or not a product is working." So, how and when should I use vitamin C serum? Learning how to layer products and when to use them is a science, but once you get your routine down, it’s super simple. Chung encourages her patients to use vitamin C serum in the morning, but you can also apply it at night with a retinol. If your skin isn’t prone to sensitivity, the combination of vitamin C and retinol may give you faster results. In you are susceptible to irritation, use a vitamin C serum in the morning and a retinol at is one must when using vitamin C and caring for your skin in general SPF. "I recommend using vitamin C every morning before sunscreen," Los Angeles-based celebrity esthetician Shani Darden tells PEOPLE. "During the day, you want to protect your skin while you're out and exposed to environmental stressors. The combo of vitamin C serum and sunscreen is perfect for daytime protection." Among her favorite vitamin C-infused serums is iS Clinical Pro-Heal Serum. She notes it's an efficacious yet nourishing serum formulated with L-Ascorbic acid, a pure and potent form of vitamin C. It is also usually well-tolerated by most skin types, including those with sensitive skin. Why Trust PEOPLE?
