Is Glycolic Acid or Niacinamide Better for Hyperpigmentation?

Published in Skincare 2 mins read

Both glycolic acid and niacinamide are popular ingredients for treating hyperpigmentation, but they work in different ways.

Glycolic Acid for Hyperpigmentation

Glycolic acid is an alpha hydroxy acid (AHA) that acts as a chemical exfoliant. It helps to remove dead skin cells and brighten the skin by promoting cell turnover. This can help to reduce the appearance of dark spots and uneven skin tone.

  • How it works: Glycolic acid breaks down the bonds that hold dead skin cells together, allowing them to slough off and reveal brighter skin underneath.
  • Benefits:
    • Reduces the appearance of hyperpigmentation
    • Improves skin texture and tone
    • Stimulates collagen production
  • Considerations: Glycolic acid can be irritating for some people, especially those with sensitive skin. It's important to start with a low concentration and gradually increase as tolerated.

Niacinamide for Hyperpigmentation

Niacinamide, a form of vitamin B3, is a powerful ingredient that can help to reduce inflammation and even out skin tone. It works by inhibiting melanin production and strengthening the skin barrier, which can help to prevent future hyperpigmentation.

  • How it works: Niacinamide reduces the activity of tyrosinase, an enzyme that plays a key role in melanin production.
  • Benefits:
    • Reduces the appearance of dark spots and uneven skin tone
    • Improves skin texture and clarity
    • Reduces inflammation and redness
  • Considerations: Niacinamide is generally well-tolerated, but some people may experience mild irritation or redness.

Which is Better?

The best ingredient for hyperpigmentation depends on your individual skin type and concerns.

  • For those with sensitive skin or a history of irritation: Niacinamide may be a better option.
  • For those with stubborn hyperpigmentation: Glycolic acid may be more effective at removing dead skin cells and revealing brighter skin.

It's important to note that both glycolic acid and niacinamide can be effective for hyperpigmentation, and they can even be used together for optimal results. Consult with a dermatologist to determine the best approach for your specific skin concerns.
