Dermatologists on the skincare aspect of TikTok recurrently tout the advantages of vitamin C, recommending customers incorporate it into their morning routines. However the worth factors for vitamin C serums are wildly totally different — why is ReVive’s serum $300 whereas The Strange’s might be discovered for just below $8?
Is that this distinction nothing greater than fancy advertising? Or does a higher-cost serum imply a greater product?
We spoke to board-certified dermatologists Dr. Angela Casey and Dr. Jeffrey Hsu, in addition to beauty chemist Ginger King, to seek out out the distinction between a high-priced and a low-priced vitamin C serum and whether or not it’s higher for shoppers to speculate or save with regards to this skincare product.
What are the advantages of vitamin C in skincare?
With an ever-increasing variety of influencers selling merchandise that promise a brand new marvel ingredient, it’s simple to develop into jaded and marvel, “Do I even want this ingredient?”
However in accordance with dermatologists, shoppers shouldn’t sleep on vitamin C.
“Vitamin C is a topical antioxidant,” mentioned Casey, an Ohio-based dermatologist. “It has anti-inflammatory results within the pores and skin; helps the pores and skin shed uninteresting, dry pores and skin cells and seem brighter by growing epidermal turnover; promotes collagen synthesis, permitting the pores and skin to develop into stronger and extra supple; and works in tandem with sunscreen to guard pores and skin cells from oxidative stress.”
With the plethora of advantages vitamin C offers to the pores and skin ― together with anti-aging, brightening and collagen manufacturing ― it’s no marvel this ingredient is a darling amongst many dermatologists.
“Consider vitamin C as an necessary step in outfitting your pores and skin to face the day forward,” Casey mentioned. “Topical vitamin C prepares the pores and skin to deal with the entire air pollution, irritation, UV injury that it encounters all through the day, and provides that additional layer of safety from environmental irritants.”
Why are some vitamin C serums a lot costlier than others?
As with all product, there’s all kinds of things that may have an effect on the totally different worth factors between two vitamin C serums.
Concentrations And High quality Management
“The standard and focus of vitamin C used within the formulation can considerably influence the value,” mentioned Hsu, an Illinois-based dermatologist.
Because the focus of vitamin C in a serum goes up, so does the value. And whereas extra will not be essentially higher with regards to this ingredient, shoppers ought to be sure their serum comprises sufficient vitamin C to be efficient.
“Customers ought to search for vitamin C concentrations between 10-20%,” Casey suggested. “Concentrations past 20% actually don’t supply any vital extra profit and might be extra irritating to the pores and skin. People with dry or delicate pores and skin ought to begin with a decrease focus of round 10%.”
However for all of this ingredient’s advantages, there may be one main draw back. In its pure kind ― ascorbic acid ― it’s infamous for expiring shortly. Nevertheless, there are a number of vitamin C derivatives that show to be extra steady than pure ascorbic acid. These merchandise can last more in your shelf, however the trade-off is that these derivatives carry the next price ticket.

Vitamin C in its pure state must be a transparent liquid. When it turns orange or brown, that’s an indication that the serum has oxidized and has misplaced a few of its efficacy.
“Pure ascorbic acid will not be steady until in a liposome kind,” King defined. ”Tetrahexyldecyl ascorbate and 3-o-ethyl-ascorbic acid are varieties of vitamin C which can be extra steady but in addition costlier.”
In the long term, it could additionally profit shoppers to pay somewhat extra for a serum from an organization that prioritizes high quality management.
“The manufacturing course of and manufacturing requirements may affect the fee,” Hsu mentioned. “Manufacturers that prioritize rigorous high quality management measures, superior formulation methods and use premium packaging supplies could command the next worth to cowl these bills.”
Further Components And Patents
“Vitamin C turns into unstable when dissolved in water,” Casey mentioned. “So combining vitamin C with complementary elements comparable to vitamin E, hyaluronic acid, ferulic acid and glutathione assist stabilize the vitamin C, thereby sustaining its efficiency and efficacy.”
Whereas these complementary elements can permit the product to last more, they’ll additionally make it costlier. SkinCeuticals’ vitamin C serum, which is available in at a whopping $180, makes use of a patented mix of nutritional vitamins C and E and ferulic acid for improved efficacy. Patents on a specific formulation may include the next price ticket for shoppers, as rival firms can not replicate their very own model of the product. (SkinCeuticals lists the odds of its energetic elements like L-ascorbic acid, vitamin E and ferulic acid, however to guard its patent, it doesn’t listing the odds of inactive elements, which might have an effect on the ultimate product.)
It might be tempting to attempt your hand at mixing your personal SkinCeuticals dupe through the use of numerous skincare merchandise that include elements like vitamin E and ferulic acid and a vitamin C powder comparable to The Strange’s 100% L-Ascorbic Acid Powder. Nevertheless, it’s greatest to go away it to the professionals.
“The vitamin E and ferulic acid within the SkinCeuticals serum are supposed to be an anti-oxidant to guard the vitamin C within the serum relatively than to offer extra pores and skin advantages that one may see in combining numerous lotions and lotions,” King mentioned. “Except SkinCeuticals specifies how a lot E and ferulic acid are of their serum formulations, you might not get the perfect advantages for anti-oxidant properties.”
Packaging And Advertising
Typically it’s merely the price of packaging and advertising that drive up the value of a specific serum.
“It’s value noting that sure retail manufacturers could apply the next markup to their merchandise solely primarily based on their model identify, irrespective of the particular formulation or elements,” Hsu mentioned. “In some circumstances of retail skincare, some notable manufacturers with a robust presence within the skincare market usually put money into in depth advertising and prime product placements in massive field shops, through which then they embody that expense within the pricing markup.”
Nevertheless, the packaging for vitamin C serums isn’t all the time only for present. The packaging can play an necessary position within the efficacy and shelf-life of the product.
“Though the branding and the field through which your bottle of vitamin C arrives don’t have any influence on the efficacy of your vitamin C serum, the bottle or tube that holds the vitamin C does,” Casey mentioned. “Vitamin C can oxidize extra quickly when uncovered to air and light-weight, so an hermetic container that’s opaque or composed of darkish glass is greatest.”
That is additionally why it’s necessary for shoppers to retailer vitamin C serums in a darkish, cool place with the highest securely closed. “Vitamin C serums which can be saved in the dead of night endure oxidative degradation at a a lot slower price in comparison with serums which can be saved in mild,” Casey mentioned.
Is it higher to pay more cash for a higher-priced serum?
Contemplating that costlier elements, packaging and formulations are typically used to create serums with prolonged shelf lives, is it higher to pay for a costlier vitamin C serum?
“It’s not higher to put money into a costlier serum solely primarily based on pricing,” Hsu mentioned. “It’s extremely beneficial to go for a standard medical-grade vitamin C product, as medical-grade skincare formulations of vitamin C have in depth scientific information and medical research supporting their efficacy.” Medical-grade skincare merchandise are solely distributed inside dermatologists’ or medical aestheticians’ workplaces, Hsu mentioned.
Quite than relying solely on the value of the product, person rankings or influencer suggestions, it’s all the time greatest for shoppers to have a look at the chilly information to get the largest bang for his or her buck.
“As dermatologists, we favor to see medical research that objectively consider the effectiveness of a vitamin C serum. Scientific proof is one of the simplest ways to match numerous serums in the marketplace,” Casey mentioned.
Nevertheless, not all information and research are created the identical. Hsu recommends that customers think about a number of elements when evaluating these research.
“Elements comparable to research dimension, measurement strategies, and whether or not the info has undergone peer assessment all influence the credibility of the knowledge,” he mentioned. “Due to this fact, an intensive evaluation is critical to make sure the validity and accuracy of the info earlier than drawing conclusions concerning the product’s efficacy.”
How do I do know if my vitamin C serum is working?
Everybody who loves skincare is accustomed to the battle of studying the medical research that assist a product’s efficacy, taking the plunge and shopping for the skincare holy grail that everybody raves about on-line… solely to seek out it doesn’t work for his or her pores and skin.
“There isn’t a ‘one-size-fits-all’ with regards to vitamin C serums,” Casey mentioned. “Simply because a sure formulation labored on your buddy or sister doesn’t imply that it’s the perfect product for you.”
So how can shoppers be sure their serum is the correct selection?
Begin With Correct Use
“I all the time advise my sufferers to use vitamin C serum as a part of their morning skincare routine as a result of antioxidant advantages and the synergistic UV-protection vitamin C provides when layered underneath your sunscreen,” Casey mentioned.
To obtain the total advantages of vitamin C, shoppers also needs to be sure they’re making use of their skincare merchandise in the correct order.
“Vitamin C is an energetic ingredient, so that you need to apply this to dry pores and skin earlier than any moisturizers or oils which might act as a barrier to the penetration of the energetic elements,” Casey suggested.
It’s also necessary to keep away from making use of vitamin C with different energetic elements comparable to retinol, AHAs and BHAs. And with regards to these with delicate pores and skin, it’s greatest to go low and sluggish with vitamin C.
“If a vitamin C serum is inflicting redness, irritation or irritation, the timing of software must be adjusted accordingly by [decreasing] the frequency of software to a few times per week,” Casey mentioned.
Consistency, Consistency, Consistency
And as with all good issues, endurance is rewarded with regards to vitamin C. Don’t anticipate any in a single day adjustments.
“Vitamin C’s job is to spice up collagen synthesis which your pores and skin ought to really feel firmer after 28 days,” King mentioned. “It additionally brightens pores and skin, and you must start to see a distinction inside 28 days.”
Taking earlier than and after footage is one other useful manner for shoppers to get proof of whether or not a specific serum is a winner or a dud for his or her pores and skin.
“I inform sufferers to take a photograph earlier than remedy after which examine a photograph, with constant angles and lighting, three months later,” Casey mentioned.
And when unsure, it’s all the time a good suggestion to seek the advice of an expert.
“Consulting with a dermatologist or medical skincare skilled can present additional steerage and monitoring on adjustments in pores and skin,” Hsu mentioned.
Odor And Shade
As vitamin C is well-known for its instability, it’s necessary to maintain a watch — and a nostril — out for any adjustments within the serum’s coloration or odor from the time it was opened.
“Vitamin C serum must be a transparent liquid; when it turns orange/brown, that’s an indication that the serum has oxidized and has misplaced a few of its efficacy,” Casey mentioned.
Some clients could discover a “burning rubber” or a “sizzling canine” odor coming from their vitamin C serums. Does a “burning rubber” odor from a vitamin C serum imply that it’s working? Or does it imply it has expired?
“Vitamin C in its pure state doesn’t have a detectable odor, however the addition of a stabilizing agent, comparable to ferulic acid, can render a burnt odor,” Casey mentioned. “Provided that vitamin C may be very unstable by itself, the good thing about including a stabilizing agent, comparable to ferulic acid, enhances the efficacy of the vitamin C energetic ingredient.”
If the serum makes use of ferulic acid, this particular “burning rubber” odor can imply that it’s “working” within the sense that it’s stopping the vitamin C from oxidizing. Nevertheless, if a vitamin C product has a noticeably unhealthy odor ― particularly if the product didn’t odor that manner when it was first opened — it could be time to throw it out.
“Any noticeable odor must be a sign that the vitamin C product has expired or degraded,” Hsu mentioned.
