When it comes to skincare actives, it can be confusing when you are trying to decide which ones to use for your skincare issues and concerns.
It gets even more confusing when you are trying to determine what actives can be used together in the same skincare routine, such as using salicylic acid with niacinamide, for instance.
Both niacinamide and salicylic acid are excellent skincare ingredients with multiple skincare benefits. So can you use salicylic acid with niacinamide in the same skincare routine?
First, let’s take a look at why you’d want to use each skincare ingredient in the first place.

The Benefits of Niacinamide
Niacinamide, also known as vitamin B3, a water-soluble vitamin, is a multi-benefit skincare active.
Niacinamide is known for its brightening properties and its ability to strengthen the skin barrier. It also has anti-inflammatory properties and helps to speed up cellular turnover.
Niacinamide has potent anti-aging properties.
This study demonstrated that a 5% concentration of niacinamide reduced the look of fine lines and wrinkles, hyperpigmentation and dark spots, blotchiness, and skin sallowness while improving skin elasticity.
Niacinamide also helps to stimulate collagen production, which can lead to a firmer more youthful-looking complexion.
Niacinamide also increases the skin’s antioxidant capacity.
Niacinamide is excellent for those with sensitive skin as it has anti-inflammatory properties and helps reduce skin irritation and redness.
If that weren’t enough, niacinamide could also be helpful for those who have oily skin and acne-prone skin.
Niacinamide helps to reduce/regulate sebum production and helps to reduce the look of enlarged pores.
Like with any skincare product, the anti-aging effects of niacinamide are dependent on the dosage applied to the skin.
While higher concentrations of niacinamide can be effective, most studies of niacinamide at 2% to 5% showed multiple benefits for the skin.
Niacinamide products are commonly formulated anywhere from 2% to 10% and even as high as 20%.
If your skin is sensitive, it is best to start out with a low concentration of niacinamide.
The Benefits of Salicylic Acid
Salicylic acid, derived from willow bark, wintergreen, and sweet birch, is a beta hydroxy acid (BHA) that exfoliates the skin.
It is a chemical exfoliant that is oil soluble, which allows it to deeply penetrate pores and unclog them, sweeping away sebum, dirt, dead skin cells, and other impurities while improving skin texture and clarity.
This makes salicylic acid a favorite for those with oily skin and for those who frequently experience breakouts and acne, as salicylic acid goes to work on whiteheads as well as blackheads.
Salicylic acid also has anti-inflammatory properties, which is another key benefit for those with acne, as it helps calm inflammation associated with acne.
Depending on the formula and your skin type, like other exfoliating acids, salicylic acid may cause irritation, redness, or peeling.
If you have sensitive or dry skin, you might be better off using alpha hydroxy acids (AHAs) like lactic acid or even glycolic acid, depending on the concentration.
If your skin is sensitive and you want to try a salicylic acid product, look for products containing lower concentrations.
NOTE: Salicylic acid increases your skin’s sensitivity to the sun, so it is important to apply a broad-spectrum sunscreen with an SPF of 30 or higher while using salicylic acid and for a week afterward.
How to Use Salicylic Acid with Niacinamide
Unfortunately, it’s not as easy as applying a salicylic acid product and then following with a niacinamide product. The reason why starts with a discussion of product pH.
pH and Your Skin
PH, or “potential of hydrogen,” measures hydrogen ions in a water-based solution. The pH scale runs from 0 – 14, with a pH of 7.0 being neutral (pure water).
Measurements under 7.0 are considered acidic, and measurements over 7.0 are considered alkaline.
While this study showed that the natural pH of skin is just under 5.0, skin is generally between a pH of 4.7 – 6.0. Skin’s natural pH is slightly acidic, and our skin’s acid mantle helps keep skin’s pH balanced.
Salicylic Acid pH and Niacinamide pH
- Salicylic acid is usually formulated with a pH of around 3.0-4.0 for optimal effectiveness and exfoliation. Therefore, salicylic acid lowers the skin’s pH to work correctly.
- Niacinamide, on the other hand, usually has a pH of approximately 5.0-7.0, with an optimal solution for stability at 6.0.
Niacinamide will increase salicylic acid’s pH if it is applied to the skin too soon after salicylic acid, which could make the products less effective or cause a skin reaction like redness or flushing.
Niacinamide Or Salicylic Acid First?
Apply salicylic acid first to exfoliate your skin and clear out your pores.
For best results, consider waiting about 30 minutes after applying salicylic acid to allow your skin’s pH level to return closer to normal.
Then apply niacinamide, whether it be a niacinamide serum or another type of skincare product, such as a moisturizer formulated with niacinamide.
Of course, you can keep both niacinamide and salicylic in your skincare routine and use them at different times of the day, such as niacinamide in the morning and salicylic acid in the evening.
Or you can alternate salicylic acid and niacinamide on different days of the week.

Final Thoughts on Using Salicylic Acid with Niacinamide
Can you use niacinamide with salicylic acid? Absolutely, if you follow the steps required to protect your skin’s pH.
Both offer the skin multiple benefits, from pore-clearing and wrinkle-smoothing benefits to skin brightening and skin barrier protection.
Combination, acne-prone, and oily skin types may benefit most from using salicylic acid with niacinamide since both offer multiple benefits for these skin types.
Be mindful of the pH of the salicylic acid and niacinamide formulas since using an exfoliating acid-like salicylic acid will lower your skin’s pH, making the pH environment incompatible with a higher pH product like niacinamide.
Be sure to allow about 30 minutes after applying salicylic acid for niacinamide application. Better yet, use them at different times of the day or on different days entirely.
