📚 Quick Study Guide
- 🔬 Tranexamic Acid (TXA): A synthetic amino acid derivative that helps reduce the appearance of dark spots and hyperpigmentation by inhibiting melanin production.
- ☀️ Sunscreen: Essential for protecting the skin from harmful UV rays, preventing sun damage, premature aging, and skin cancer.
- 🤝 TXA + Sunscreen: Combining TXA with sunscreen provides enhanced protection against hyperpigmentation by both reducing melanin production and preventing UV-induced melanin synthesis.
- 🗓️ Consistency is Key: For optimal results, use both TXA and sunscreen daily as part of your skincare routine.
- 🧴 Application Order: Apply TXA serum or treatment before sunscreen in your morning routine.
