The power couple for oily and acne-prone skin.
Salicylic acid and niacinamide are two topical ingredients that are trending in the skincare world—and as someone who’s been using them for years, I couldn’t be happier. One is a beta-hydroxy acid (BHA), and the other is a form of vitamin B3. Together, they’re especially helpful for oily skin, enlarged pores and adult acne. But even if you don’t deal with those conditions, they actually offer a long list of benefits for every skin type. However, figuring out where these ingredients go in your skincare routine can be confusing. Can you apply them at the same time, or even in the same product? Will one inactivate the other? And in what order should you layer them? I’ll be answering all of those questions and more in this tutorial. You will learn what salicylic acid and niacinamide can do for your skin, how to use them in your routine the right way, and the best products that I recommend trying. What Does Salicylic Acid Do for Your Skin?Salicylic acid is a chemical exfoliant and the most well-known BHA or beta-hydroxy acid. The BHA family also includes betaine salicylate and willow bark extract, which are gentler alternatives. Here’s what salicylic acid and other BHAs do for your skin:
What Does Niacinamide Do for Your Skin?Niacinamide is a form of vitamin B3, a water-soluble vitamin that plays an important role in restoring cellular energy and helping cells to carry out their functions. Here’s what niacinamide does for your skin:
Should You Use Both Salicylic Acid and Niacinamide in Your Routine?While salicylic acid and niacinamide are each effective on their own, there are synergistic benefits from using both in one routine. If you’re only using salicylic acid, then you won’t get the barrier-strengthening support of niacinamide. Since it is a chemical exfoliant, salicylic acid can make your skin feel drier, especially when you’re first starting treatment. (That said, it is still far less irritating than glycolic acid, due to its higher molecular weight.) Adding niacinamide to your routine can help to counteract any side effects from the acid by increasing your skin’s ability to retain moisture, supporting barrier function and reducing redness. On the flip side, if you’re only using niacinamide, then your pores won’t get the deep-cleaning that salicylic acid can provide. While niacinamide has shown positive results for mild to moderate acne, it plays more of a supporting role by reducing oil. It can’t remove dead skin cells or dislodge clogged sebum like salicylic acid can. Adding salicylic acid to your routine will do more to clear existing breakouts and prevent future acne. As you’ve probably noticed, there’s also an overlap in what these two ingredients can do. They control excess oil, smooth the skin texture, minimize pores and fade discolourations. But they work through different pathways—so by using both, you can target these issues in two different ways for the best possible results. Can You Mix Salicylic Acid and Niacinamide Together?Mixing salicylic acid and niacinamide together, or layering one ingredient on top of the other at the same time, is a no-no. Here’s why. Decreased Absorption of Salicylic AcidIn order to penetrate the skin and work as it should, salicylic acid is formulated with an acidic pH, typically between 3.0 and 4.0. A study comparing salicylic acid at various pH levels (pH 2.0, 5.0 and 7.0) found that the higher the pH, the less the skin absorbs.[22] In contrast, niacinamide is formulated with a neutral pH, usually around 6.0. So if you mix salicylic acid and niacinamide together, the niacinamide can raise the pH level of the acid, making it less acidic. That means less salicylic acid will be able to get into your skin, so it won’t be as effective. The “Niacin Flush”Mixing salicylic acid and niacinamide can also affect the performance of your niacinamide. Like I said, it normally has a neutral pH, but acidic conditions can trigger its conversion into niacin, another form of vitamin B3.[23] Niacin is notorious for producing the “niacin flush”—an episode of hot, red, flushed skin due the release of prostaglandin D2.[24] If you’ve ever taken an oral niacin supplement, you’ve no doubt experienced it, but it can also happen when you use salicylic acid and niacinamide at the same time. Fortunately, it’s only temporary, but when this happened to me, it lasted a couple hours (and there’s no way I could have covered it up with makeup!). I suspect this may be why some people believe that they are having a “reaction” to salicylic acid, niacinamide or both. It could simply be from applying them too close together in your routine. Scroll to Continue How to Use Salicylic Acid and Niacinamide the Right WayFortunately, you can still use salicylic acid and niacinamide in the same routine. Here are your best options: 1. Apply Them in a Single ProductTaking two separate products and mixing them together isn’t a good idea, but you can try a pre-made formula that includes both salicylic acid and niacinamide in its ingredients list. Unlike a DIY concoction, it’ll be expertly formulated to be stable and effective at certain pH (which brands often disclose). The downside is that it likely won’t be as potent. The concentration of active ingredients will probably be lower, and the pH level may not be as acidic. However, this trade-off may be worth it to you for a convenient, all-in-one product. If so, here are a few options:
2. Apply Them at Different Times of DayIf you’d rather maximize your results by using two separate products, the easiest way to apply them is at different times of day. Both ingredients are safe to use day or night, depending on your preference. I find that most people like to use their niacinamide serum in the morning because it has the same neutral pH level as most moisturizers and sunscreens. So, you can apply it underneath your hydrators and sun protection without needing to wait in between layers, since it won’t affect their performance. Salicylic acid needs to be separated from higher-pH products by about 30 minutes, to give it enough time to work at its lower (acidic) pH. Most of us have more time to incorporate this waiting period at night. So, you’d apply your salicylic acid to bare skin after cleansing, and then wait half an hour before proceeding with any hydrating serums or night creams. 3. Apply Them on Alternate Mornings or NightsYou can also try using your salicylic acid on alternating mornings or nights. So, one morning you could apply salicylic acid after cleansing, and the night morning, niacinamide. Or, you could do the same thing at night, depending on what works best with your skincare routine. Again, you’ll want to be mindful of pH levels when layering your other products on top of these ingredients. My general rule is that whenever two skincare products are more than about pH 1.0-2.0 apart, I incorporate a 30-minute waiting period. 4. Apply Them 30 Minutes ApartBut what if you want to apply salicylic acid and niacinamide at the same time of day? Well, you can—but you do need to allow for a waiting period in between them. Acidic products always go on first, so in this case, it would be your salicylic acid. It should be applied to clean, bare skin, and left for 30 minutes so that it can do its thing and fully absorb. This waiting period also allows time for your skin’s pH to return from an acidic state to its normal, higher level (around 5.5). After the time is up, you can proceed with the niacinamide, as well as any other hydrators and/or SPF. In my experience, 30 minutes is the “magic” number to prevent flushing from an unwanted conversion to niacin. Depending on how well your skin tolerates the acid, you can apply these ingredients as often as once or twice per day.

Conclusion + Further ReadingSalicylic acid and niacinamide are two ingredients that are always in my skincare routine. Together, they keep oil in check, calm my redness, and reduce breakouts and any dark marks left behind. Whenever I’m asked about oily skin or acne, they are my go-to recommendation as a “first line of treatment.” However, I personally believe that there’s a place for both ingredients in most skincare routines, even if you don’t deal with these skin conditions. Since salicylic acid has a high molecular weight and anti-inflammatory properties, it is actually a great exfoliant for all skin types. You just need to choose the appropriate strength and frequency for your skin. Niacinamide, of course, is non-irritating and boasts a wide range of benefits, even at low concentrations. Whether you apply them at different times of day, on alternating days or nights, or 30 minutes apart is up to you. Just remember to always use them away from each other, so that each ingredient can work at its optimal pH level for best results. Further Reading

Can we use salicylic acid hyaluronic and niacinamide together?Can I use salicylic acid with hyaluronic acid and niacinamide? Yes, you can, believe it or not! With the potent, anti-bacterial and anti-acne benefits of salicylic acid quite often there is the side effects of severe skin dryness and irritation.
Can you use hyaluronic acid and salicylic acid at the same time?Hyaluronic acid is a skin hydrator, not an exfoliant like salicylic acid. You can definitely use both. In fact, applying hyaluronic acid with your salicylic acid is a very good idea. Salicylic acid can be a little drying to the skin because it's job is to absord excess oil.
Should I use hyaluronic acid or salicylic acid first?Usually, it's recommended that you use hyaluronic acid after salicylic acid to prevent dryness. However, if your hyaluronic acid is in your cleanser and your salicylic acid is in your serum, then you would apply your hyaluronic acid first. Just be sure to use a moisturizer after your salicylic product.
