Lecture on Niacinamide in Skincare

Introduction

• Niacinamide (Vitamin B3 derivative) is prevalent in skincare.
• Many frustrated by lack of results.
• Misunderstandings on its usage.

What is Niacinamide?

• Known as a jack of all trades, master of none.
• Helps with various skin conditions: aging, acne, skin barrier health.
• Not a hero ingredient; it's a supporting actor.

Common Issues with Niacinamide

• Present in many skincare products.
• Overuse can cause irritation.
• Effective concentration: Less than 5%, preferably 2%.
• High concentrations (>10%) are often unnecessary and can cause irritation.

Form and Efficacy

• Stable ingredient, effective in various product forms (serum, cream, etc.).
• Leave-on products more effective than rinse-off ones.
• Does not need a specific product form to be effective.

Using Niacinamide in Skincare Routine

• Dark Spots: Niacinamide helps minimally. Requires a comprehensive regimen targeting all steps of pigmentation.

  • Retinoids as primary treatment.
  • Combine with ingredients like kojic acid, tranexamic acid, vitamin C, etc.
  • Prescription options like Truma.

• Oil Control: Niacinamide helps regulate oil production.

  • Best paired with salicylic acid.
  • Difficult to control oil without prescription treatments.

• Acne: Niacinamide alone is insufficient.

  • Best paired with retinoids like adapalene.
  • Consider azelaic acid if pregnant.

• Skin Barrier: Niacinamide supports barrier health.

  • Pair with ceramides for enhanced effect.

• Redness: Limited options over the counter; pair niacinamide with azelaic acid.

• Pores: Combine with salicylic acid or retinol for structural changes.

• Antioxidant Role: Functions uniquely through NADPH regeneration.

  • Pair with vitamin C or copper peptides for enhanced antioxidant benefits.

Additional Considerations

• Skincare is highly personalized.
• Results vary based on individual skin conditions and complete routines.
• Visiting a dermatologist can be helpful for persistent issues.

Conclusion

• Niacinamide is a versatile ingredient but should be strategically paired for best results.
• Consider skin type and specific concerns when integrating into routine.
• Seek professional advice if necessary.
