If you’ve ever battled acne, chances are you’ve tried a handful of spot treatments, detox masks, or harsh cleansers hoping to calm the breakouts and fade the scars. Maybe some of the acne treatments worked temporarily, but chances are that they left your skin irritated, dry, or worse, made everything flare up again. You might be left grasping at ideas to clear up your skin, which has led you to wonder - does niacinamide help with acne?
The truth is, when it comes to managing oily skin, breakouts, and long-term discoloration, the goal isn’t just drying pimples out, but it’s about balancing your skin for optimum health. And one ingredient that does just that? Niacinamide.
Niacinamide, also known as vitamin B3, is one of the most versatile and gentle active ingredients in modern skincare. It tackles breakouts by calming inflammation, reducing excess oil, shrinking the look of enlarged pores, and fading stubborn acne scars over time. It's no wonder dermatologists love recommending niacinamide for acne, and why this powerhouse ingredient has become a must-have in countless skincare routines for young and old alike.
One serious perk of niacinamide that cannot be overlooked is that it plays nicely with other acne-fighting ingredients like salicylic acid, making it easy to build a successful skincare regimen that works without overwhelming your skin.
In this guide, we’ll break down exactly how niacinamide helps reduce breakouts and heal acne scars, how to choose the best niacinamide serum (we LOVE Eight Saints’ Original Cin Niacinamide 10% Facial Serum), and how to add it to your daily skincare routine, especially if you have oily skin or deal with clogged pores. By the end, you’ll see why niacinamide is more than just a trend; it’s your skin’s new best friend.
What Is Niacinamide and Why It’s a Skincare Superstar
Niacinamide, also known as vitamin B3, is a well-researched, dermatologist-favorite ingredient in skincare products. It delivers multiple benefits for acne-prone skin:
- Reduces sebum production, helping oily and acne-prone skin stay matte.
- Anti-inflammatory action calms redness and irritation around blemishes
- Unclogs and tightens pores, reducing the appearance of clogged pores and enlarged openings.
- Brightens dark spots and acne scars, as niacinamide helps block pigment transfer and promote cell turnover.
- Strengthens the skin barrier, increasing resistance to irritants and locking in moisture.
These perks make niacinamide a cornerstone for treating oily skin, acne, and visible acne scars, plus it pairs smoothly with other active components like salicylic acid.
Salicylic Acid + Niacinamide: The Clear-Skin Power Duo
When you team up niacinamide with salicylic acid, you create an acne-fighting powerhouse that is sure to impress you with real results.
Salicylic acid, a beta-hydroxy acid (BHA), is known for:
- Penetrating deep into pores to dissolve oil, debris, and dead cells
- Acting as a keratolytic agent to prevent clogged pores and reduce acne.
- Offering anti-inflammatory benefits, further reducing swelling around breakouts.
Used together in a routine, niacinamide calms the skin and controls surface oil, while salicylic acid clears pores from within. This balanced approach addresses pores, oil, acne, and acne scars effectively and gently.
Niacinamide and Acne: Proven Benefits
Let’s explore the benefits of using niacinamide to combat acne and prevent scarring.
Sebum Regulation
Overactive sebaceous glands produce excess oil that clogs pores, leading to acne. Niacinamide helps regulate oil flow, preventing new blemishes
Pore Unclogging
By reducing debris and controlling oil, niacinamide helps keep pores clear, which reduces blackheads and whiteheads.
Scar and Dark Spot Reduction
Topical niacinamide inhibits pigment transfer and supports healing, fading acne scars and hyperpigmentation over time.
Barrier Repair & Calm
Its anti-inflammatory nature soothes irritated acne-prone skin and strengthens the protective barrier.
Choosing the Best Niacinamide Serum
Look for:
- Concentration: 5–10% niacinamide is ideal for gentle but effective results, with 10% being common in high-performance serums.
- Empty fillers: Opt for lightweight, non-greasy bases (e.g., glycerin, hyaluronic acid—not heavy emollients).
- Synergy boosters: Ingredients like hyaluronic acid hydrate, while zinc PCA adds oil control.
- Free-from status: Clean formulations avoid parabens, silicones, and fragrances—perfect for sensitive, acne-prone skin.

How to Use Niacinamide in Your Routine
Here’s a step-by-step skincare routine:
Cleanser
Use a gentle, low-pH wash to clear impurities without disrupting your skin barrier.
Niacinamide serum
Apply 2–3 drops of Eight Saints Original Cin after salicylic acid absorbs. Pat gently over face and neck.
Hydrator
Follow with a moisturizer—ideally one containing humectants and occlusives to lock in hydration.
Sunscreen (AM only)
Finish with at least SPF 30 to shield against UV rays and prevent dark spots from worsening.
At night, incorporate a retinoid or vitamin C, but separate from niacinamide if irritation occurs. Adjust salicylic acid frequency based on sensitivity; niacinamide can be used daily.
Skincare Routine for Oily, Acne-Prone Skin
- Morning: Use a cleanser that contains salicylic acid toner/serum. Then apply a niacinamide serum followed by a lightweight moisturizer with SPF.
- Evening: Use a cleanser that contains salicylic acid. Apply a niacinamide serum followed by a richer moisturizer or retinoid formula.
Niacinamide stabilizes the benefits of salicylic acid and supports barrier repair overnight.
Addressing Acne Scars with Niacinamide
Yes, niacinamide helps with acne scars. Its dual-action—reducing inflammation and preventing further hyperpigmentation—makes it an effective tool against post-breakout marks.
Combine with treatments like chemical peels, retinoids, or laser therapy for faster, more dramatic scar fading—but niacinamide remains a gentle, everyday staple.

Frequently Asked Questions About Niacinamide for Acne-Fighting
Does niacinamide help with acne scars?
Yes, niacinamide is one of the best ingredients for fading acne scars, especially the dark marks left behind after a severe breakout. It works by slowing the transfer of melanin to the skin’s surface and supporting healthy cell turnover, which helps even out skin tone over time. While it won’t erase deep pitted scars, it’s incredibly effective for post-inflammatory hyperpigmentation (PIH). With consistent use, your scars will gradually fade and your skin tone will take on a more even appearance.
Can I use niacinamide with salicylic acid?
Absolutely! Niacinamide and salicylic acid make an excellent team for oily, acne-prone skin. Salicylic acid clears out clogged pores and exfoliates, while niacinamide calms the skin, reduces redness, and balances oil. Together, they target acne from multiple angles without over-drying or irritating the skin, which is a common problem when using harsher acne skincare products.
Is niacinamide good for oily skin?
Absolutely! Niacinamide is a powerhouse for oily skin. It helps regulate sebum production, which means less shine and fewer breakouts caused by excess oil. Plus, it tightens the look of pores and helps improve your skin’s texture, making it smoother and more refined over time, without stripping or drying your skin out like some oil-control products do.
How long does it take for niacinamide to work on acne?
Everyone’s skin is different, but most people start noticing improvements within 2 to 4 weeks of consistent use of niacinamide. Redness and inflammation may start to calm down first, followed by fewer breakouts and smoother skin texture. Fading acne scars can take longer, maybe around 6 to 8 weeks, but staying consistent with a high-quality product like Eight Saints Original Cin Niacinamide Serum can make a big difference.
Can niacinamide clog pores or cause breakouts?
Niacinamide itself is non-comedogenic, meaning it won’t clog your pores. In fact, it helps prevent clogged pores by reducing oil and calming inflammation. However, make sure the product you’re using has a clean, lightweight formula without heavy oils or fillers, like Eight Saints Original Cin, which is specifically designed for acne-prone and sensitive skin types.
When should I apply niacinamide in my skincare routine?
Niacinamide should be applied after cleansing and toning, but before heavier creams or oils. If you use salicylic acid, apply that first and let it fully absorb into your skin, then follow with your niacinamide serum. Finish your daily skincare routine with moisturizer and SPF (in the morning). This layering approach helps each product do its job effectively and keeps your routine simple but powerful. Now remember, your nighttime routine will be slightly different.
