Hey Reader!

​

UV rays don’t just burn—they cause oxidative stress, which leads to collagen breakdown, dark spots, and premature aging. Antioxidants and tyrosinase inhibitors, especially Vitamin C, help neutralize that.

Science says: Vitamin C helps reduce UV-induced damage, boost collagen synthesis, and even enhance the efficacy of your SPF. It also prevents the formation of melanin, which can worsen post-inflammatory hyperpigmentation or cause the formation of sun spots during the summer.

What to look for:​
✔️ A serum with 10–20% L-ascorbic acid (the most studied form)
✔️ Paired with Vitamin E and Ferulic Acid for enhanced stability and performance
✔️ Store it away from light and heat to preserve potency

​
✨ Apply Vitamin C in the AM, then follow with SPF for max protection and glow.
