A vital nutrient that has multiple skincare benefits, Niacinamide can help minimize the appearance of acne scarring. People with skin prone to acne can relate to the frustration of having undesired marks that often crop up at the most inopportune times. Acne scars can appear just as worrying and may persist longer if improper care is not taken.

By providing the skin with the necessary nutrients for a balanced and healthy appearance, nourishing substances like niacinamide can help to reduce the appearance of acne scars.

Discover the advantages of niacinamide and begin using it in your regular skincare regimen for skin types that are prone to acne.


Nicotinamide, another name for niacinamide, is a kind of vitamin B3. It is a nutrient that is soluble in water that helps to improve skin tone and is especially good for skin that is sensitive. This important component can assist in maintaining the skin's ceramide supply, which is necessary for maintaining the skin's protective barrier and preventing skin irritants from penetrating the skin.

Niacinamide also has the added benefit of increasing the synthesis of collagen, which helps to plump up the skin, and breaking down excess melanin, which reduces the appearance of pigmentation and dark spots.

Niacinamide is a very helpful component for treating acne scars because it has so many various skin advantages in one single dose.


Oil (sebum) trapped in clogged pores causes frequent and chronic skin lesions that are associated with acne. Bacterial multiplication can exacerbate this trapped oil, which can result in the creation of a pimple.

These kinds of recurrent breakouts might cause unsightly acne scars, depending on the individual's past. Two primary forms of acne scars can appear: a raised lump on the skin or an indentation in the skin caused by a loss of skin tissue.

While some acne scars are deeper and more permanent without the help of good skincare, others are more superficial and will heal rather fast. Acne scarring is not a common occurrence in those with acne-prone skin, and it is typically the skin's reaction to these frequent breakouts.

How Does Skin React to Niacinamide?

Now, let's talk about some fundamental science. Two significant compounds, nicotinamide Adeline dinucleotide (NAD+/NADH) and nicotinamide Adeline dinucleotide phosphate (NADP+), are precursors of niacin (and hence niacinamide/nicotinamide). These substances are essential to the chemical processes that your skin cells go through in order to develop, heal, and perform as intended.

The mechanisms underlying the topical advantages of niacinamide on the skin are believed to be the same: promoting the body's production of NAD+ and damaging cell repair. 

Niacinamide's Benefits for Skin

Almost all skin types can benefit from niacinamide, and its advantages are too good to pass up:

  • Treats Rosacea, Mild Acne, and Other Inflammatory Skin Conditions:

    Niacinamide is a useful treatment for skin inflammation because of its anti-inflammatory qualities.

  • Controls Sebum:

    Topical niacinamide has the potential to reduce the production of oil, which may be advantageous for those who have acne-prone skin.

  • Diminishes Wrinkles And Fine Lines:

    Topical niacinamide helps the skin manufacture ceramides, which are lipids that support the skin's protective and safety barrier. This helps the skin retain moisture and reduces the look of wrinkles and fine lines.

  • Contributes To Plump And Youthful Skin:

    It also encourages the skin to produce more hyaluronic acid, which helps the skin retain moisture, and collagen, which gives the skin its suppleness.

  • Reduces Pore Appearance:

    Niacinamide aids in the skin's production of protein, especially keratin. Usage gradually smoothes out the texture of the skin, which reduces the visibility of pores.

  • Reduces Pigmentation And Guards Against Sun Damage:

    Niacinamide helps produce healthy skin cells and shield the skin from harmful environmental elements including pollutants, UV radiation, and toxins.

Pigmentation and Niacinamide

Let's examine how pigmentation and scarring affect our skin.

The three layers of our skin are the hypodermis, which is the innermost layer composed of connective tissue and fat, the dermis, which is the mid-layer containing sweat glands and hair follicles, and the epidermis, which is the outermost layer of protection. When the dermis is harmed (by a wound or injury), scars develop. In order to repair the damage, our body produces new collagen fiber, which gives the damaged tissue a distinct texture and quality than the surrounding tissue.

When exposed to direct sunshine, the skin also becomes tanned and pigmented. The area becomes darker as a result of the body's natural defense system producing a lot of melanin quickly.

In order to properly fade scars, it is crucial to select a formulation that allows the molecules to quickly penetrate the skin's surface and target the dermis, which is the location of the blemish root.

Since niacinamide has anti-inflammatory properties, it can be used to treat inflammation of the skin. Additionally, it fixes and shields cells from environmental harm. The molecules that carry out the chemical reactions necessary for skin cells to proliferate, heal damage, and operate normally are precursors of vitamin B3.

Therefore Niacinamide will assist in reducing inflammation, which initially causes scarring. However, it is not a treatment for tough acne scars that already exist.

With the plethora of the products in the market it really gets difficult to choose the correct serum for your healthy skin. Try out this

How to Handle Pigmentation and Acne Scars?

Effective scar treatment requires the use of exfoliating and bleaching chemicals, such as Alpha Hydroxy Acids (AHAs), which are skin-friendly acids that have strong anti-aging properties in addition to helping to lighten the skin. The most auspicious ones are:

Glycolic Acid:

Glycolic acid works well to lighten dark spots and is a mild chemical exfoliator. Dead skin cells are shed to expose fresh, younger, and more vibrant skin cells. It can disrupt the connections between dead skin cells and penetrate deeper into the skin because of its lower molecular size. It may initially produce some stinging and pinkness when it exfoliates the skin's outermost layer, but these adverse effects normally go away after a few uses as the skin becomes accustomed to the cream.

Ideal for normal to oily/combination skin types is glycolic acid. Skin irritation and redness are more common adverse effects in people with dry and extremely sensitive skin. It shouldn't be combined with other strong exfoliants, such as retinoid, because it is a strong exfoliator on its own.

Lactic Acid:

The gentlest of the AHAs, lactic acid is the softer sibling to glycolic acid. It's a great choice for dry and sensitive skin because of its moisturizing qualities. It functions by sloughing off the outermost layer of skin and deeply removing debris, oil, and dead skin cells that are obstructing the pores. It is a non-friction type exfoliator that dissolves and breaks down the connections that hold dead skin cells together.

Just like other of the compounds on this list that lighten skin, lactic acid also prevents the synthesis of melanin. It is an excellent choice for treating sunburn, acne scars, uneven patches, dark spots, and wrinkles and fine lines. It also smooths out the texture of the skin. 

Alpha Arbutin:

The naturally occurring substitute for the popular skin-lightening chemical hydroquinone is arbutin. Bearberries, mulberries, blueberries, cranberries, wheat, and certain types of pears are the sources of arbutin.

Alpha Arbutin, glycosylated Hydroquinone, is the pure water-soluble, biosynthetic active component that is used in the majority of formulations. Arbutin's hydroquinone group enables it to directly suppress the formation of melanin by tyrosinase, leaving skin clearer and more radiant.

Arbutin is effective for slightly bleaching pigmentation on all skin types and tones. Arbutin functions best when combined with AHA and Vitamin C to increase its effectiveness. Research indicates that kojic acid is a more effective treatment for hyperpigmentation than arbutin.


Retinoids are one of the few chemicals on the market that have been shown to be successful in reversing the symptoms of age, making them the absolute holy grail for skin prone to acne. The broad term "retinoid" refers to the vast family of chemical compounds generated from vitamin A that brighten the skin, promote the creation of collagen, raise the cell turnover ratio, remove hyperpigmentation, and soften fine lines and wrinkles.

Because they are kinder and safer for dry and sensitive skin, retinol, retinyl esters (retinyl palmitate, retinyl acetate, and retinyl linoleate), and adapalene are typically present in lesser concentrations in the majority of over-the-counter retinoids. On the other hand, the stronger prescription retinoids target wrinkles and acne in normal skin by containing either tretinoin or retinoic acid, depending on the concentration.

Why Is Niacinamide Useful?

For treating skin issues like wrinkles, fine lines, and hyperpigmentation, niacinamide is a more gentle option. especially if you are looking for stronger choices, like prescription retinoids or other antioxidants like vitamin C, and your skin is really sensitive.  

Potential Side-effects and Considerations while using Niacinamide:

Skin Irritation:

Although most people tolerate niacinamide well, some people may find their skin becomes red or irritated, especially when using high dosages or in conjunction with other active components.

Niacinamide allergy:

Niacinamide allergy responses are uncommon but do occur. Immediately stop taking niacinamide and get medical help if you develop any side effects, including a rash, hives, swelling, or trouble breathing.

Oral niacinamide

Supplements have the potential to induce moderate gastrointestinal symptoms, including nausea, vomiting, diarrhea, and upset stomach. Reduce the chance of these adverse effects by taking niacinamide with food.

Liver Function:

Some people's liver function may be impacted by high niacinamide dosages, especially when taken orally. Before using supplements containing niacinamide, anyone with liver illness or those taking drugs that impact liver function should speak with their pharmacist.

Blood Sugar Levels

Niacinamide may have an impact on blood sugar levels, especially in persons who have diabetes or are taking blood sugar-controlling drugs. If a diabetic is using niacinamide supplements, careful monitoring of blood glucose levels is advised.

Medicine Interactions:

Blood thinners, cholesterol-lowering medicines (such statins), and niacinamide supplements may interact with some medications. If you are using any drugs at the moment, it is crucial that you speak with your doctor before beginning niacinamide supplements.

Pregnancy and breastfeeding:

Although oral supplements should only be taken under a doctor's supervision, topical niacinamide is usually regarded as safe during these times.

Sun Sensitivity:

Because niacinamide does not raise the risk of sunburn or cause photosensitivity, it is appropriate for usage in skincare products during the day. Actually, studies have demonstrated the photoprotective properties of niacinamide, which may enhance the skin's ability to withstand UV rays.

How Is Niacinamide to Be Used?

Which type of product you should use is mostly determined by your skin type. 

A water-based serum is advised for oily skin types.

Emollient moisturizers or moisturizing toners with a lower niacinamide content are recommended for dry skin.

Niacinamide: Is it safe?

It is generally accepted that topical niacinamide is safe to use, even during pregnancy and lactation. 

However, those with sensitive skin and a history of allergies are encouraged to perform a patch test before usage or see a dermatologist. If your skin is really sensitive, you might wish to start with a lesser concentration (5 percent).

When Are Results Visible?

You must be persistent and patient, just as with any skincare regimen and product. Four weeks is usually when noticeable results, such as toned, moisturized skin, and silky texture, become apparent.

Take note:

All things considered, niacinamide is a versatile, well-tolerated substance that has several advantages for both general wellbeing and skin health. If you have any worries or have any negative reactions, it's imperative that you use it safely and consult a doctor.

Always confirm your diagnosis before beginning a self-treatment program
