Oily skin comes with its own set of problems like clogged pores, acne, and an uneven skin texture. In India, the humid climate, pollution, and sweating make these problems seem even more severe. This is why skincare ingredients like salicylic acid and niacinamide have become so popular in the skincare routine.
Both salicylic acid and niacinamide are great ingredients, but they have different properties and functions. Understanding the differences between salicylic acid and niacinamide can help you choose the best one according to your skin type and needs, especially if you are a beginner or intermediate in your skincare routine.
This article explores the properties of both ingredients, their differences, who should use them, and if they can be used together.
What Is Niacinamide?
Niacinamide is a vitamin B3 derivative and is known to be gentle and effective on the skin. It primarily targets improving the skin’s overall health rather than exfoliating.
A strong skin barrier helps to maintain the skin’s moisture levels and makes it more resilient to environmental stressors like pollution and heat.
Advantages of Using Niacinamide
- Controls oil production
- Improves skin barrier
- Reduces redness and irritation
- Evens out skin tone and reduces pigmentation
- Shrinks pores
Because of its soothing properties, niacinamide is considered to be safe for all skin types, including oily, sensitive, dry, and combination skin.
According to PWC, a double-blind, placebo-controlled trial showed that topical niacinamide (about 2%) significantly reduced sebum excretion (oil production) in subjects after repeated use—proving its efficacy on one of the fundamental characteristics of oily skin.
What Is Salicylic Acid?
Salicylic acid is a beta hydroxy acid (BHA) that is extracted from various sources, such as the bark of the willow tree. Salicylic acid is oil-soluble, which means it can easily pass through oil and penetrate deep into the pores.
This makes salicylic acid highly effective for oily and acne-ridden skin, where excess oil often mixes with dead skin cells to clog pores.
Advantages of Using Salicylic Acid
- Deeply cleans clogged pores
- Exfoliates dead skin cells
- Helps to reduce blackheads and whiteheads
- Helps to control excess oil on the skin
- Improves overall skin texture
However, there are also milder versions of salicylic acid, such as willow bark extract and betaine salicylate, which may be more tolerable for sensitive skin types.
According to a study published by PMC, salicylic acid is effective for mild to moderate acne, but results and potency may vary depending on the product formulation and concentration. It is recognized for its ability to improve acne lesions and excess oil over time.

Salicylic Acid vs Niacinamide: Key Differences
| Aspect | Salicylic Acid | Niacinamide |
| How it works | Exfoliates the skin and cleans pores deeply | Calms, repairs, and balances the skin |
| Main focus | Removes excess oil and dead skin cells | Regulates oil and strengthens the skin barrier |
| Targets | Clogged pores, acne, blackheads, congestion | Redness, uneven tone, enlarged pores |
| Effect on oily skin | Clears oil buildup inside pores | Helps control oil without drying the skin |
| Skin improvement type | Treats active pore-related issues | Improves overall skin quality and resilience |
| Best used for | Oily, acne-prone skin with frequent breakouts | Oily or combination skin needing balance and repair |
Salicylic Acid or Niacinamide: Which Is Better for Acne?
When acne is the priority, it is essential to know the benefits of each ingredient, as acne has various causes. It can be triggered by oily skin, clogged pores, inflammation, or a compromised skin barrier.
Salicylic acid targets clogged pores directly. It is oil-soluble, so it can penetrate pores that are congested with oil and dead skin cells. This helps to remove the blockage that usually results in blackheads, whiteheads, and active acne. Because of this, salicylic acid is more effective at treating active acne on oily skin.
Niacinamide, on the other hand, helps acne management in a more subtle way. It helps to regulate excess oil, reduce redness, and restore the skin barrier. Although it does not remove pores as effectively as salicylic acid, it is a vital component in preventing future breakouts and restoring the skin.
In short:
- For active breakouts and clogged pores → Salicylic acid
- For inflamed, sensitive, or recurring acne → Niacinamide
- For long-term acne management → Using both carefully can be helpful
Which Is Better for Oily and Acne-Prone Skin?
Oily and acne-prone skin needs both oil regulation and skin barrier restoration. This makes the salicylic acid vs niacinamide debate more about application than competition.
Salicylic acid is ideal when oily skin leads to:
- Frequent pimples
- Blackheads and whiteheads
- Congested or rough skin texture
It helps to remove excess oil and dead skin cells from deep within the pores, treating acne at its core.
Niacinamide is best suited for oily skin that:
- Shines excessively but breaks out easily
- Gets irritated or red from using harsh products
- Has large pores
It helps to regulate oil production without drying the skin and balances the skin as a whole.
How to use oily and acne-prone skin?
- Apply salicylic acid 2-3 times a week to maintain clean pores
- Apply niacinamide daily to balance oil and firm the skin
Both products can be used together for better results than using one alone.
