Everything You Ever Wanted to Know About Niacinamide: The Multitasking Skincare Ingredient You're Missing

If niacinamide has not yet found its way into your skincare routine, perhaps it's time to give it a shot. While many people are fixated on more-talked-about ingredients like retinol and vitamin C, niacinamide serves as a true multitasker that deserves attention. Known for its versatility, it can benefit almost every skin type, even sensitive skin, and addresses a multitude of issues. Dermatologists and skincare experts break down the benefits of niacinamide, how to use it, and why it should be on your radar.

What Is Niacinamide?

Niacinamide, otherwise referred to as nicotinamide, is one of the forms of vitamin B3, important for skin well-being. According to Dr. Gretchen Frieling, a dermatopathologist, a B vitamin, it controls many critical functions in skin cells, so it is very often added to skincare. Niacinamide is available naturally in various foods, including vegetables, fish, milk, and eggs. It can be applied topically through creams and serums to address a multitude of problems on the skin related to acne and aging.

Topical Versus Oral Niacinamide

Niacinamide could be used both topically and orally, though the two differ in the purposes they are used for. While topical niacinamide is safe to use on the skin for many days, oral niacinamide is generally used for the treatment of acute deficiency of vitamin B3 in the diet, especially in the management of pellagra, and always under medical supervision due to side effects.

Main Advantages of Niacinamide for Skin

1.       Acne and Oil Control

Niacinamide can be a lifesaver for acne-prone or oily skin. According to dermatologist Kenneth Howe, "Niacinamide reduces sebum production, which controls shine and prevents acne." Also, niacinamide has anti-inflammatory properties, making it suitable for acne-related redness and eczema. Look for such products as EltaMD AM Therapy Facial Moisturizer or Cosrx AC Collection Lightweight Soothing Moisturizer, which combine niacinamide with hydrating ingredients that help to keep skin both oily and sensitive.

2.   Barrier Repair

 Niacinamide boosts the barrier in the skin, which is especially helpful for sensitive skins or eczema. By strengthening the barrier, it protects the skin from moisture loss and environmental interference. Dr Howe says that it also improves hyperpigmentation as it inhibits pigment transfer to the skin, so really, it's great for dark spots too.

3.       Wrinkle Reduction and Anti-Aging

Niacinamide also supports anti-aging by encouraging healthy cell function and repairing DNA damage. Studies show using products with niacinamide over a few weeks can drastically reduce the depth of wrinkles and stimulate collagen productions to make skin more elastic. A multi-purpose fight against signs of aging is found in a daily-use niacinamide for youthful, resilient skin.

How to Use Niacinamide in Your Skincare Routine

Niacinamide can be introduced into your regime easily during the day and at night. Here's how:

Apply to Clean Skin: Niacinamide serums should be applied to freshly washed skin, otherwise it can't penetrate deeply enough.

Moisturizer and SPF: After niacinamide, apply moisturiser and, if using it in the morning, sunscreen. Leave a few minutes between applications to allow each product time to sink in.

If irritation is experienced, its use should be reduced and a dermatologist consulted. Although niacinamide is usually well tolerated, sensitive skin types always should patch test any new products.

A Combination of Niacinamide with Other Ingredients:

1. Niacinamide + Salicylic Acid

As far as oily skin, niacinamide could also be combined with salicylic acid, a beta-hydroxy acid that dissolves oil and clears pores. The combination is often used in oily skin face washes, bringing about oily control and anti-inflammatory benefits.

2. Niacinamide + AHAs Alpha-Hydroxy Acids

Alpha-hydroxy acids (like glycolic or lactic acid) pair well with niacinamide because they exfoliate the skin, thereby improving niacinamide absorption. Combining both can also help to alleviate irritation caused by stronger exfoliants, so niacinamide is a brilliant companion for smoother, clearer skin.

3. Niacinamide + Hyaluronic Acid

Both niacinamide and hyaluronic acid are hydrating. When used together, this is ideal for dryness because niacinamide holds in moisture while strengthening the barrier, and hyaluronic acid pulls moisture into the skin, creating a powerhouse duo for hydration.

4. Niacinamide + Vitamin C

While the combination of niacinamide with vitamin C is debatable, the two can be used very effectively when applied separately at least 15 minutes apart or when one is applied in the morning and the other in the evening. For those in need of combining brightening benefits without a separate application step, products are formulated with both ingredients.

5. Niacinamide + Retinol

While it is understood that retinol offers a range of anti-aging benefits, sometimes it can cause irritation. Thus, niacinamide, with its calming effects, will complement retinol without causing any discomfort and redness while maximizing the effects of retinol on wrinkles.

Who Can Use Niacinamide?

Niacinamide is versatile enough for most skin types, from dry to oily. Its soothing, barrier-strengthening properties make it ideal even for sensitive skin. "One of niacinamide's best qualities is that it's relatively gentle and well-tolerated," says Dr. Howe. As always, it's a good idea to patch-test to ensure there are no adverse reactions.
