What Is a Tyrosinase Inhibitor?

How to Prevent Pigmentation and Common Myths

Pigmentation is one of the most common concerns we treat at Richmond Skin & Laser, and also one of the most misunderstood.

Many clients come in using the “right” products but still struggling with stubborn pigment that won’t budge. Most of the time, the missing piece is understanding how pigmentation actually forms, and where tyrosinase inhibitors come in. Tyrosinase is an enzyme in the skin responsible for producing melanin (pigment).When your skin is exposed to triggers like UV, heat, inflammation, or hormones, this enzyme becomes more active leading to excess pigment production.

Tyrosinase inhibitors work by slowing down this process.
In simple terms, they help switch off the pigment production pathway before it fully develops.

Common examples you might see in your skincare include:

  • Vitamin A (retinoids)
  • Vitamin C
  • Niacinamide
  • Kojic acid
  • Azelaic acid


But here’s the key, they don’t remove pigment instantly, they prevent new pigment from forming while existing pigment is treated.

Why You’re Still Getting Pigmentation

Even if you’re using tyrosinase inhibitors, pigmentation can persist if the triggers aren’t controlled. At Richmond Skin & Laser, we often see pigmentation driven by:

  • UV exposure (even on cloudy days)
  • Heat (saunas, hot yoga, long hot showers)
  • Blue Light (phones, laptops, LED lighting an screens).
  • Inflammation (acne, over-exfoliation, aggressive treatments)
  • Hormones (melasma-prone skin)


This is why treating pigmentation is never just about one product, it’s about a holistic approach.

Habits That Help Prevent Pigmentation

If pigmentation is your concern, these daily habits are just as important as your treatments.

  • SPF every single day
    Broad spectrum Zinc SPF 50+, reapplied, no exceptions.

  • Zinc-based SPF helps physically protect the skin from UVA and UVB exposure while also being gentle on sensitised or post-treatment skin. Consistent SPF use is one of the most important steps in preventing pigmentation from worsening.

  • Manage heat exposure

  • Be mindful of excessive heat on the skin

  • Support your barrier

  • Over-exfoliating can make pigmentation worse

  • Be consistent with your activities

  • Tyrosinase inhibitors only work if used regularly

  • Treat inflammation early

  • The faster you calm the skin, the less chance pigment will form

  • Reduce unnecessary blue light exposure

  • Blue light from screens and devices may contribute to pigmentation, especially in melasma-prone skin. Antioxidants and iron oxide-containing SPF products can help provide additional protection.

Common Pigmentation Misconceptions

“I can just peel it off.”

 Not quite. While treatments like chemical peels can help lift pigment, they don’t stop it from coming back if the underlying triggers aren’t addressed.

“Once it’s gone, it’s gone.”

 Pigmentation can be a chronic condition for many people. Without maintenance it can return.

“I only need SPF when I’m outside or it's Summer."

Pigmentation can be a chronic condition for many people. Without maintenance, it can return. UV exposure happens through windows, while driving, and during daily activities. Incidental exposure adds up, Even in Winter. Blue light exposure from screens and indoor lighting can also contribute to pigmentation concerns over time.

“Stronger = better.”

Overusing actives can inflame the skin and actually worsen pigmentation.
