The Benefits of Niacinamide

You might be wondering why you should even consider a niacinamide serum since there are so many other actives that address skin concerns.

What makes niacinamide so special is that it has many skincare benefits, including:

  • Reduces the appearance of fine lines and wrinkles
  • Improves uneven skin tone
  • Minimizes the size of pores
  • Improves the texture of the skin
  • Strengthens the skin’s natural moisture barrier
  • Brightens dull skin
  • Minimizes redness, inflammation, and the weakened skin barrier associated with certain skin conditions such as acne and rosacea

Niacinamide is suitable for most skin types, but as you increase concentration percentages, you increase the risk of irritation.

It is best to start with a lower concentration and gradually increase it as your skin adjusts.

How To Use Niacinamide in Your Skincare Routine

If you’re new to niacinamide or have sensitive skin, always perform a patch test. This involves applying a small amount of the product on a small patch of skin, such as the inside of your wrist, to see if there’s any adverse reaction.

Apply After Cleansing and Toning

Before applying niacinamide or any serum, ensure that your skin is clean. Begin with a gentle cleanser to prepare your skin.

In skincare (including Korean skincare), the general rule is to apply products from the thinnest to thickest consistency. Niacinamide serums usually have a lightweight texture, so apply your niacinamide serum after cleansing and toning but before heavier creams or oils.

Layering Niacinamide With Other Actives

Niacinamide can be used in combination with many other skincare ingredients like hyaluronic acid, peptides, and antioxidants.

Some suggest exercising caution when using it alongside vitamin C (ascorbic acid), as combining them might reduce the effectiveness of the ingredients. You can read more about using niacinamide and vitamin C together in my post: Can You Use Niacinamide with Vitamin C?

After applying your niacinamide serum, apply a moisturizer to lock in its benefits and provide an additional hydration layer. This is particularly essential if you have dry or combination skin.

Don’t Forget Sunscreen (AM Skincare Routine)

While niacinamide can help protect the skin from environmental damage, it doesn’t substitute for sunscreen. Ensure you apply a broad-spectrum sunscreen every morning, especially if you’re using skincare products that make your skin more sensitive to the sun.

Many Korean sunscreens offer advanced formulas that provide high sun protection and are formulated with skin-loving ingredients.

Be Consistent

Like all skincare ingredients, the benefits of niacinamide become most evident with consistent use. Keep it as a staple in your routine to see transformative results over time.

Incorporating niacinamide into your skincare routine can be a game-changer. By understanding its benefits and using it correctly, you’re on your way to brighter, more even-toned, and healthier skin.

The Bottom Line

The single best Korean niacinamide serum? It depends on your needs.

These niacinamide serums are excellent choices for combination, oily, acne prone skin since niacinamide targets acne, breakouts, and excessive oil production.

COSRX The Niacinamide 15 Serum and Neogen and Dermalogy Real Niacinamide Serum are some of my favorites for their high 15% niacinamide concentrations.

AXIS-Y Dark Spot Correcting Glow Serum is another favorite, as it has a nourishing formula and hydrates my skin, especially when irritated.
