The skincare ingredient world is packed (and we imply filled with a capital P) with gamers. It appears as if day-after-day a brand new one hits the already-crowded scene, promising to be the subsequent neatest thing. Nonetheless, regardless of the newbies that come and go together with a predictable regularity, there are a handful of substances that stay tried-and-true, staples with scientifically-proven results. Amongst these, niacinamide and vitamin C are arguably two of the largest names on that brief listing. Every boasting a plethora of advantages, the query then turns into this: If they will do such nice issues individually, can or ought to they be used collectively? Is it a peanut-butter-and-jelly situation (you already know, the place every factor is nice by itself, however actually manner higher when paired with the opposite)? Or can combining these two powerhouses trigger issues? There’s lots of conflicting recommendation on the subject, so we requested consultants to set the document straight.
First, let’s discuss every ingredient individually.
Earlier than we get to the potential points that may come up when combining the 2, it is vital to grasp what these substances are and what they will do to your pores and skin on their very own.
Niacinamide is a type of vitamin B3 (also referred to as niacin) that’s, “a wonder ingredient with a multitude of benefits,” says Chicago dermatologist Emily Arch, MD. “Among its many attributes, it helps skin produce ceramides to improve barrier function and hydration, increases collagen production to help with the appearance of fine lines and pores, inhibits excess sebum production, and may help lighten discoloration,” she provides. As if that weren’t sufficient, it is also been proven to have anti-inflammatory results (notably helpful for these with zits and rosacea), and is a robust antioxidant, in accordance with board-certified dermatologist Charlotte Birnbaum, MD of Spring Avenue Dermatology in New York Metropolis. In different phrases, it doesn’t matter what your complexion concern could also be, niacinamide can most likely assist.
Vitamin C is not far behind in terms of boasting a prolonged listing of advantages. Arch calls it her, “favorite skincare ingredient, hands down,” lauding it for its potent antioxidant properties and skill to neutralize free radicals earlier than they will trigger injury. And like niacinamide, it additionally has anti-aging results. Vitamin C is essential for collagen manufacturing, bettering the look of superb strains and wrinkles, and reduces the manufacturing of pigment to assist lighten darkish spots, explains Birnbaum.
So, can you employ niacinamide and vitamin C collectively?
The brief reply to your query: sure, you possibly can. Something you might have learn that claims in any other case relies on outdated analysis that does not translate to an actual world situation. “Some research done in the 1960s showed a negative interaction and that the two could potentially react to produce nicotinic acid, which can cause redness and itching in the skin,” explains Perry Romanowski, an impartial beauty chemist. The massive caveat? “That occurred when using pure ascorbic acid and niacinamide held at high temperatures,” he continues. “It’s unlikely to be a problem in modern day formulations stored at room temperature.” (Price noting: Most skincare merchandise use totally different, extra steady types of vitamin C similar to ascorbyl palmitate and magnesium ascorbyl phosphate, quite than ascorbic acid.) It is also price declaring that vitamin C is of course present in our pores and skin: “If the two ingredients weren’t compatible, we’d all suffer when using topical niacinamide,” says Arch.
This is why you must use them each (and the way to take action).
Okay, so we all know combining the 2 is not going to be problematic, however will it’s helpful? Once more, the brief reply is sure. “Given the multitude of benefits of both of these ingredients, and the complimentary nature of these benefits, they’re a powerful combination,” says Arch. Despite the fact that they each goal numerous indicators of getting older, they’ve barely totally different mechanisms of motion, so that you’re addressing the problem from numerous angles. Take pores and skin brightening, for instance. Combining the 2 might be useful as a result of they’re working in numerous methods to attain this impact, notes Romanowksi. Vitamin C works by inhibiting an enzyme referred to as tyrosinase, needed for the manufacturing of pigment, whereas niacinamide is assumed to forestall the switch of pigment inside cells.
So far as the precise manner to make use of niacinamide and vitamin C collectively, you possibly can both search for one product that accommodates each or layer them individually, although the consultants we spoke with agree that layering is preferable. That is just because vitamin C is a notoriously unstable molecule, simply rendered inactive by publicity to daylight, oxygen, and even different substances. Plus, “generally speaking, vitamin C needs to be used at a low pH in order to be effective, while niacinamide works better at a higher/neutral pH,” provides Romanowski. (Its fussy nature is why many vitamin C merchandise skew on the pricier aspect; it is a powerful ingredient to formulate with.) Arch recommends utilizing a stand-alone vitamin C product for the entire aforementioned causes, although does observe that different antioxidants, particularly vitamin E and ferulic acid, can really improve the efficacy and even stability of vitamin C. (Living proof: The Skinceuticals C E Ferulic serum beloved by dermatologists and sweetness editors all over the place.) Regardless, irrespective of which vitamin C product you choose, ensure hold it out of the solar and warmth, provides Birnbaum.
Niacinamide, then again, is way much less delicate and finicky than vitamin C, says Arch. Yow will discover it in loads of serums, moisturizers, masks, and extra, at quite a lot of value factors. However in terms of which ingredient ought to go in your pores and skin first, it would not actually matter. Your finest wager is to resolve primarily based on the formulation of the actual merchandise you are utilizing, making use of them from thinnest to thickest, advises Arch. In different phrases, a serum would at all times go earlier than a moisturizer, and an oil ought to at all times be utilized final.
TL; DR: Niacinamide and vitamin C are each veritable energy gamers within the skincare world in their very own proper. And mixing them not solely is not an issue, it is really an amazing transfer in your quest for for a brighter complexion.
