What is Salicylic Acid?

Salicylic acid is a beta-hydroxy acid (BHA) – a skincare superhero renowned for its exfoliating prowess.

Editor’s tip: The BHA family also includes betaine salicylate and willow bark extract, which are gentler alternatives.

What Does Salicylic Acid Do for Your Skin?

Here’s what salicylic acid and other BHAs do for your skin:

  • Deep-cleans pores: Since salicylic acid and other BHAs are oil-soluble, they penetrate deep into your pores, remove excess oil, and loosen clogged sebum. (Source)
  • Clears acne: Salicylic acid can help keep your pores clean and remove excess oil and dead skin cells. Thus, it can clear acne and prevents blackheads when used regularly.
  • Exfoliates and smooths: Salicylic acid exfoliates dead skin cells, improving your skin’s overall texture and keeping it smoother.
  • Reduces pore size: Salicylic acid helps smooth your skin’s surface, reducing the appearance of pores. Also, it penetrates deep into pores, keeping them clean and thus minimizing their size. (Source)
  • Controls sebum production: It helps regulate sebum production, which can help with oily skin. (Source)
  • Fades acne scars and marks: Salicylic acid can fade and minimize the appearance of post-acne marks and scars.

What is Niacinamide?

Niacinamide is a form of vitamin B3 – unsung hero among active ingredients in skincare, offering a myriad of benefits.

What Does Niacinamide Do for Your Skin?

Here’s what niacinamide does for your skin:

  • Reduces redness: Niacinamide can help fight redness (even rosacea) and reduce skin irritation. (Source)
  • Controls excess oil: It balances out sebum production and can be beneficial for people with oily skin. (Source)
  • Minimizes pores: Niacinamide reduces pore size by reducing oil production.
  • Strengthens skin barrier: It helps your skin retain moisture and prevent trans-epidermal water loss to keep your skin healthy and strong.
  • Reduces wrinkles and fine lines: Because niacinamide boosts collagen production, it can help reduce the appearance of fine lines and wrinkles. (Source)
  • Fades pigmentation and evens skin tone: It can face hyperpigmentation and improve your skin tone.

Needless to say, this water-soluble active ingredient is a true multitasker, leaving your skin looking and feeling fabulous.

Niacinamide can be used alone or layered with other ingredients like retinol or tretinoin for added benefits.

In fact, many dermatologists recommend using niacinamide with prescription retinoids because it helps prevent irritation from the medication while still providing similar results.

Can You Use Salicylic Acid and Niacinamide Simultaneously?

If you want to reap the benefits of both ingredients, how should you go about it?

How should you layer salicylic acid and niacinamide in your skincare routine?

And most importantly: Should you layer salicylic acid and niacinamide on your skin in the first place?

These two active ingredients are like a power couple working in tandem, addressing various skin concerns. While salicylic acid dives deep to cleanse your pores, niacinamide swoops in to soothe and nourish your skin. Together, they’re a dream team for a complexion that radiates health.

So yes, you can use salicylic acid and niacinamide in your skincare routine. But whether you should use them simultaneously and how you should layer them depends on your skin type.

Let’s see how you should use these ingredients to get the best results next.

How to Start Using Salicylic Acid and Niacinamide?

Clearly, salicylic adic and niacinamide deliver great benefits for a variety of skincare concerns.

But if you’re new to these ingredients, you should start slowly and see how your skin reacts. You don’t want to irritate your skin and cause any redness.

With that said:

Avoid layering salicylic acid and niacinamide altogether when you first introduce them to your skincare regime.

Both ingredients can be quite harsh especially if you have sensitive skin. That’s why you want to give your complexion some time to get used to them gradually.

So how should you use salicylic acid and niacinamide, then?

Why You Shouldn’t Layer Salicylic Acid and Niacinamide

Contrary to popular belief, mixing salicylic acid and niacinamide together or layering one ingredient on top of the other at the same time can actually hinder their effectiveness and even lead to unpleasant side effects.

Here are two reasons why you shouldn’t layer salicylic acid and niacinamide:

Reason 1: Decreased Absorption of Salicylic Acid

Salicylic acid is a beta-hydroxy acid (BHA) that works best at an acidic pH level, typically between 3.0 and 4.0. At this pH, it can effectively penetrate the skin and unclog pores.

However, when mixed with niacinamide, which typically has a neutral pH of around 6.0, the overall pH of the mixture increases, reducing salicylic acid’s effectiveness.

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. This means that mixing salicylic acid and niacinamide can significantly reduce the amount of salicylic acid that reaches the deeper layers of the skin, hindering its ability to clear pores and treat acne.

Reason 2: The “Niacin Flush”

Niacinamide, a form of vitamin B3, is generally well-tolerated by the skin. However, when combined with salicylic acid, it can trigger a reaction known as the “niacin flush.”

This reaction occurs when niacinamide is converted into niacin, another form of vitamin B3, under acidic conditions. Niacin causes the release of prostaglandin D2, a vasodilator that dilates blood vessels, leading to a sudden flush of redness, warmth, and tingling, especially on the face and neck. (Source)

The niacin flush is usually temporary and harmless, but it can be quite uncomfortable and even embarrassing. It can also make it difficult to apply makeup, as the flushed skin may be more sensitive and prone to irritation.

I’ve experienced the niacin flush a few times when I started using these two ingredients together. It’s nothing too dangerous – just a bit unpleasant with a tingling sensation and redness. If you’re in a rush and need to apply makeup in the morning, you want to be mindful of how to prevent it.

How to Use Salicylic Acid and Niacinamide the Right Way

To avoid these adverse effects, you use salicylic acid and niacinamide separately. This way, you can maximize their effectiveness and minimize the risk of unwanted side effects.

The best way to layer salicylic acid and niacinamide is to use them at different times of day.

Our team has seen the best results and less skin irritation from this routine:

  1. Use salicylic acid in the evening – You can find this ingredient in cleansers, toners, masks, and topical spot treatments.
  2. Use niacinamide in the morning – You can find this ingredient in serums, toners, moisturizers, and sunscreens.

Alternatively, you can use these ingredients together on alternate mornings and evenings:

  1. Use salicylic acid in the morning or evening on one day.
  2. Use niacinamide in the morning or evening on the next day.

Once your skin gets used to these ingredients, you can indeed layer them in the same routine. Acidic products always go on first, so in this case, it would be your salicylic acid.

Here’s how to layer salicylic acid and niacinamide the right way:

  1. Apply salicylic acid first, as it needs a slightly acidic environment to work effectively.
  2. Wait for at least 30 minutes to allow the first product to absorb fully.
  3. Follow with niacinamide.

By using these two ingredients separately or layering them with a 30-minute break in between applications, you can maximize their effectiveness and minimize the risk of unwanted side effects.

FAQ: How to Layer Salicylic Acid and Niacinamide

How do I know if my skin can tolerate salicylic acid and niacinamide?

Before incorporating salicylic acid and niacinamide into your skincare routine, it’s important to perform a patch test. Apply a small amount of each product to an inconspicuous area of skin, such as the inner elbow, and wait 24 hours. If you experience any redness, irritation, or discomfort, discontinue use and consult a dermatologist.

What is the best order to apply salicylic acid and niacinamide?

We recommend incorporating these ingredients into your skincare routine by using them separately at first. Once your skin gets used to them and you want to layer salicylic acid and niacinamide, start with salicylic acid followed by niacinamide with a 30-minute break in between applications. Salicylic acid is a leave-on exfoliant, so it should be applied first to allow it to penetrate the skin effectively. Niacinamide, being a water-soluble ingredient, can be applied afterward.

How often should I use salicylic acid and niacinamide?

Start by using salicylic acid and niacinamide once a day, preferably in the evening. If your skin tolerates them well, you can gradually increase the frequency to twice a day if needed. However, if you experience any dryness or irritation, reduce the frequency or consult a dermatologist for personalized advice.

Can I use salicylic acid and niacinamide with other skincare products?

Yes, you can use salicylic acid and niacinamide with other skincare products and active ingredients, such as cleansers, toners, moisturizers, and sunscreens. Choose products that are gentle, non-comedogenic, and formulated for your skin type.

What are some of the best salicylic acid and niacinamide products for different skin types?

For oily and acne-prone skin, consider products with higher concentrations of salicylic acid, such as Paula’s Choice BHA 9 Liquid or COSRX Low pH Salicylic Acid Gentle Cleanser. For dry or sensitive skin, opt for products with lower concentrations of salicylic acid and a focus on hydration, such as Cerave SA Renewing Cleanser or La Roche-Posay Effaclar Medicated Gel Cleanser.

How long does it take to see results from using salicylic acid and niacinamide?

The time it takes to see noticeable results from using salicylic acid and niacinamide varies depending on individual skin concerns and skincare routine. Generally, salicylic acid delivers results within a few days, while with niacinamide you can expect to see some improvement within a few weeks.

Are there any potential side effects of using salicylic acid and niacinamide?

Salicylic acid can cause dryness, irritation, and redness, especially in individuals with sensitive skin. Niacinamide can trigger the “niacin flush,” a temporary flushing of the face and neck accompanied by warmth and tingling. Start with lower concentrations and gradually increase as your skin tolerates it.

Final thoughts

Harnessing the power of salicylic acid and niacinamide can transform your skincare routine and reveal a clearer, healthier complexion.
